What if I told you... that you could run a website from behind Cloudflare and only have 385 daily requests miss their cache and go through to the origin service?
No biggy, unless... that was out of a total of more than 166M requests in the same period:
Yep, we just hit "five nines" of cache hit ratio on Pwned Passwords being 99.999%. Actually, it was 99.9998% but we're at the point now where that's just splitting hairs, let's talk about how we've managed to only have two requests in a million hit the origin, beginning with a bit of history:
Optimising Caching on Pwned Passwords (with Workers)- @troyhunt - https://t.co/KjBtCwmhmT pic.twitter.com/BSfJbWyxMy
— Cloudflare (@Cloudflare) August 9, 2018
Ah, memories 😊 Back then, Pwned Passwords was serving way fewer requests in a month than what we do in a day now and the cache hit ratio was somewhere around 92%. Put another way, instead of 2 in every million requests hitting the origin it was 85k. And we were happy with that! As the years progressed, the traffic grew and the caching model was optimised so our stats improved:
There it is - Pwned Passwords is now doing north of 2 *billion* requests a month, peaking at 91.59M in a day with a cache-hit ratio of 99.52%. All free, open source and out there for the community to do good with 😊 pic.twitter.com/DSJOjb2CxZ
— Troy Hunt (@troyhunt) May 24, 2022
And that's pretty much where we levelled out, at about the 99-and-a-bit percent mark. We were really happy with that as it was now only 5k requests per million hitting the origin. There was bound to be a number somewhere around that mark due to the transient nature of cache and eviction criteria inevitably meaning a Cloudflare edge node somewhere would need to reach back to the origin website and pull a new copy of the data. But what if Cloudflare never had to do that unless explicitly instructed to do so? I mean, what if it just stayed in their cache unless we actually changed the source file and told them to update their version? Welcome to Cloudflare Cache Reserve:
Ok, so I may have annotated the important bit but that's what it feels like - magic - because you just turn it on and... that's it. You still serve your content the same way, you still need the appropriate cache headers and you still have the same tiered caching as before, but now there's a "cache reserve" sitting between that and your origin. It's backed by R2 which is their persistent data store and you can keep your cached things there for as long as you want. However, per the earlier link, it's not free:
You pay based on how much you store for how long, how much you write and how much you read. Let's put that in real terms and just as a brief refresher (longer version here), remember that Pwned Passwords is essentially just 16^5 (just over 1 million) text files of about 30kb each for the SHA-1 hashes and a similar number for the NTLM ones (albeit slight smaller file sizes). Here are the Cache Reserve usage stats for the last 9 days:
We can now do some pretty simple maths with that and working on the assumption of 9 days, here's what we get:
2 bucks a day 😲 But this has taken nearly 16M requests off my origin service over this period of time so I haven't paid for the Azure Function execution (which is cheap) nor the egress bandwidth (which is not cheap). But why are there only 16M read operations over 9 days when earlier we saw 167M requests to the API in a single day? Because if you scroll back up to the "insert magic here" diagram, Cache Reserve is only a fallback position and most requests (i.e. 99.52% of them) are still served from the edge caches.
Note also that there are nearly 1M write operations and there are 2 reasons for this:
An untold number of businesses rely on Pwned Passwords as an integral part of their registration, login and password reset flows. Seriously, the number is "untold" because we have no idea who's actually using it, we just know the service got hit three and a quarter billion times in the last 30 days:
Giving consumers of the service confidence that not only is it highly resilient, but also massively fast is essential to adoption. In turn, more adoption helps drive better password practices, less account takeovers and more smiles all round 😊
As those remaining hash prefixes populate Cache Reserve, keep an eye on the "cf-cache-status" response header. If you ever see a value of "MISS" then congratulations, you're literally one in a million!
Full disclosure: Cloudflare provides services to HIBP for free and they helped in getting Cache Reserve up and running. However, they had no idea I was writing this blog post and reading it live in its entirety is the first anyone there has seen it. Surprise! 👋
I think I've pretty much captured it all in the title of this post but as of about a day ago, Pwned Passwords now has full parity between the SHA-1 hashes that have been there since day 1 and NTLM hashes. We always had both as a downloadable corpus but as of just over a year ago with the introduction of the FBI data feed, we stopped maintaining downloadable behemoths of data.
A little later, we added the downloader to make it easy to pull down the latest and greatest complete data set directly from the same API that so many of you have integrated into your own apps. But because we only had an API for SHA-1 hashes, the downloader couldn't grab the NTLM versions and increasingly, we had 2 corpuses well out of parity.
I don't know exactly why, but just over the last few weeks we've had a marked uptick in requests for an updated NTLM corpus. Obviously there's still a demand to run this against local Active Directory environments and clearly, the more up to date the hashes are the more effective they are at blocking the use of poor passwords.
So, Chief Pwned Passwords Wrangler Stefán Jökull Sigurðarson got to work and just went ahead and built it all for you. For free. In his spare time. As a community contribution. Seriously, have a look through the public GitHub repos and it's all his work ranging from the API to the Cloudflare Worker to the downloader so if you happen to come across him say, at NDC Oslo in a few months' time, show your appreciation and buy the guy a beer 🍺
Lastly, every time I look at how much this tool is being used, I'm a bit shocked at how big the numbers are getting:
That's well more than double the number of monthly requests from when I wrote the blog post about the FBI and NCA only just over a year ago, and I imagine that will only continue to increase, especially with today's announcement about NTLM hashes. Thank you to everyone that has taken this data and done great things with it, we're grateful that it's been put to good use and has undoubtedly helped an untold number of people to make better password choices 😊
Cybersecurity professionals are often perceived as sole practitioners, plying their craft in dimly lit rooms. Nothing could be further from the truth, as one of the keys to being a successful cybersecurity professional is the ability to collaborate and, more importantly, to share knowledge as far and wide as possible.
At Cisco, we have formed the Cisco Insider Advocacy program, which consists of a global community of professionals passionate about working and spreading their knowledge with others. We celebrate these individuals’ efforts with annual awards in various disciplines and locales. In 2023, Cisco will recognize top advocates by region for the Global Advocate Awards. Our first event – highlighting Cisco customers from across the EMEA region – is around the corner. It all happens at Cisco Live in Amsterdam, in a live ceremony on February 8!
I am joined on the Advocate Awards judges’ panel by my colleagues, Cindy Valladares, Director of Brand Strategy and Customer Advocacy at Cisco Secure, Caroline Surujpaul, EMEA and European Marketing Director at Cisco Secure and Sarah Stephens, Senior Security Marketing Leader for EMEA at Cisco Secure. We are pleased to introduce the nominees for the Cybersecurity Defender of the Year Award in EMEA.
We have five distinguished nominees, and while we have yet to select a winner, you will see how each of their contributions to Cisco’s cybersecurity community raised our attention.
Alessandro was featured in a recent successful case study about the Future of Work with Umbrella, as well as an earlier piece about simplified security using Cisco Meraki in Talent Garden.
Alessandro also authored a book about digital transformation long before it was a common buzzword. That is typical of Alessandro’s foresight, the ability to be proactive to changes before they are commonplace. He is indeed on the cutting edge.
Alessandro considers his involvement in the Advocacy community as “a very easy goal for me. First, because I’m very passionate about cybersecurity, and second because here I can find very valuable peers and professionals to share information with.” Alessandro’s abilities are borne from passion, drive, and adherence to a personal code of excellence; he learned security in a strictly hands-on style. He is also a member of Cisco’s “League of Cybersecurity Heroes.”
Christoffer, the newest Cisco Insider Advocacy community member, has gotten off to a brisk involvement with the group. He was recently featured in the case study “NTNU Supports a Diverse Academic and Research Community with Proactive Security,” which detailed how the Norwegian University of Science and Technology tackled the management of a dizzying 110,000 endpoints connecting to the university’s VPN.
Christoffer fully embraces the ideology of collaboration, mentioning that when he was seeking a security solution, “We didn’t want a vendor. We didn’t want a product. We wanted a partner to help us attack this large problem of cybersecurity.” He also demonstrates a fervent dedication to sharing by authoring half a dozen works in the cybersecurity realm, ranging from scientific to academic articles. His involvement in the Insider Advocacy community has earned him a spot in Cisco’s “League of Cybersecurity Heroes.”
Mark is one of the most erudite cybersecurity professionals one could meet. He has extensive educational credentials and enjoys sharing his knowledge, making him one of the Top 10 most engaged advocates of the Cybersecurity Channel within the Cisco Insider Advocates community.
Mark’s professional involvement extends beyond his local precinct, offering his knowledge of security best practices across the UK Policing community. In completing his most recent university degree, he authored a dissertation that “has led to an initiative to improve the security posture of my workplace.” Mark’s support to other Cisco customers has also led to his election as Vice-Chair of the Internet Society Cybersecurity Special Interest Group. He is also a member of Cisco’s “League of Cybersecurity Heroes.”
Luigi is a valuable member of the Insider Advocacy group and was recently featured in a video and written success story about Zero Trust and XDR.
Luigi is an agent of change who embraces the collaborative spirit of a true cybersecurity expert, as exemplified in his entire professional approach: “Since the infrastructure is now cloud-based, we had to change our mindset regarding cybersecurity as well. It was important to have the people, the process, the organisation, and the technology under the same security umbrella.”
When not working to ensure the security of the Sara Assicurazioni environment, Luigi has dedicated time to speaking at events, such as the “Experts Learning from Experts” global virtual session, a special virtual roundtable dedicated to Zero Trust and, last but not least, his presentation at Cisco Live Emea in Amsterdam about XDR and Zero Trust. His contributions to the Insider Advocacy platform reflect a tireless commitment to the cybersecurity community. Luigi is also a member of Cisco’s “League of Cybersecurity Heroes.”
Last year, Diego participated as speaker at the Tech Forum: Convergencia entre redes y seguridad. He will also be featured in a future ThreatWise TV – Cisco episode
Diego recognised early on that remote work would place his organisation outside the scope of their security and took proactive measures to meet the challenge. Part of his proactive approach is to freely communicate his ideas, leading to his involvement in the Insider Advocacy community. This has also earned him a place within Cisco’s “League of Cybersecurity Heroes.”
Diego’s view of working with Cisco’s products is summed up in a catchy phrase: “If it’s connected, it’s protected.” His involvement within the Insider Advocacy community makes us echo that sentiment by stating that he is connected, helping to keep everyone protected.
One point of note is the absence of women from the list of nominees. This was not the result of bias, as Cisco has a history of substantial diversity, equity, and inclusion. As you can see from the activities of the current nominees, the selection was based strictly on contributions to the community. We would love to see more engagement and membership in the Insider Advocacy program, not only from women but from a broader geographic area. This would increase the choices of possible nominees and add an even wider palette of inclusion to the entire nomination process.
We know that there is an entire population of cybersecurity professionals who seek more connection with like-minded individuals, and we welcome you to join this cohesive community.

There are no ifs, ands, or buts about it: A stolen identity creates a mess. Once they have a few key pieces of personally identifiable information (PII), an identity thief can open new credit lines, create convincing new identities, and ruin an innocent person’s good credit.
If you suspect you’ve been affected by identity theft, acting quickly is key to stopping the thief and repairing the damage. Here are the definitive five steps of identity remediation, or the process of restoring and protecting the privacy of your identity.
With a stolen identity in hand, thieves can open new lines of credit or apply for large loans using someone else’s excellent credit score for leverage. If undetected, fraudsters can run up huge bills, never pay them, and in turn, ruin the credit score that you spent years perfecting. When you suspect or confirm that your identity has been compromised and you’re in the United States, alert the three major credit bureaus: Equifax, TransUnion, and Experian.
Freezing your credit means that no one (not even you) can open a new credit card or bank account. This prevents criminals from misusing your identity. Initiating a credit freeze is free and it doesn’t affect your credit score.
Once you suspect a criminal has stolen your identity, file a report with the Federal Trade Commission. Its official identity theft website includes a form for you to detail the circumstances. From there, the FTC will investigate.
It’s important to file a report because law enforcement can get involved and hopefully stop the criminal from striking again. Also, an official document from law enforcement or the FTC may help your bank and the credit bureaus resolve the damage.
Whenever a company with which you have an account is breached, the first step you should take is to quickly change your password. The same goes for when your identity is compromised with the added step of getting in touch with your banks and asking their fraud department to issue you new credit and debit cards and put them on alert for possible suspicious charges.
Having unique passwords for all your accounts is crucial to keeping them secure. For instance, if one of your accounts is breached and a cybercriminal lifts that username and password combination, they may then attempt to use it on other sites. To ensure you have strong passwords and passphrases for every site, consider using password manager software. Password managers are incredibly secure and make it so you only have to remember one password ever again.
In addition to freezing your credit, you may have to sync up with each bureau to remedy any damage the identity thief may have done to your credit. Each bureau’s fraud department is very familiar with these scenarios, so their customer service department is experienced and more than willing to help you work through it.
Once you’ve cleaned up the immediate mess made by an identity thief, it’s important to continuously monitor your identity in case the thief is biding their time or pieces of your PII are still circulating on the dark web. Plus, the headache of one compromised identity incident is enough for someone to never want it to happen again. Identity monitoring is a very thorough process that will give you peace of mind that you’ll be protected and can enjoy your online life safely.
These five steps, while important, can be tedious. It may require a lot of patience to sit on hold and sift through all the relevant forms. Luckily, McAfee is an excellent partner who can help you with all your identity remediation needs with just one service: McAfee+ Ultimate. For example, security freeze is an easy way to put a halt on your credit. McAfee’s identity monitoring service monitors up to 60 unique types of personal details. If your PII appears on the dark web, Personal Data Cleanup can remove it.
Recover and move forward confidently after an identity theft with McAfee by your side.

Oh, the scammers online are frightful, and the deals they offer seem delightful. No matter what you think you know, let it go, let it go, let it go (to the tune of 1945’s Let it Snow by Vaughn Monroe with the Norton Sisters).
‘Tis the season to find ourselves awash in good tidings and, well, consumerism. While it’s only partly tongue in cheek, we must be honest with ourselves. We spend a lot of money online. Often, we find ourselves leaving things to the last minute and hope that the delivery folks can make the magic happen and send us all the widgets and grapple grommets while we surf the Internet from the safety of our sofas with coffee in hand.
But, not every deal is what it appears to be. Scammers are always lurking in the void of the Internet waiting for a chance to fleece the unexpecting from their hard-earned money. This can manifest itself to the unsuspecting in many ways. There are shipping frauds, gift card giveaways and vishing (phone-based scams).
Scams tend to rely on generating a false sense of urgency. The shipping scam emails often show up in our inboxes as a warning about a missed or delayed package that will be sent back to the point of origin if we don’t answer quickly. Of course, this requires a payment to receive the fictitious package.
These types of shipping scam emails are quite effective this time of year when more often than naught many people have enough orders coming to their house to make a fort with the empty boxes.
The other kinds of attacks are the gift card scams and vishing. The first of which taps into the sense of excitement that a person might receive something for free. “Fill out this form with your credit card information for a chance to win a $200 gift card.” Sadly, this attack works well for older generations for which giveaways were more common and they aren’t as accustomed to spotting digital swindlers.
The last scam that we will tackle here is often labeled as vishing or voice phishing. This is a method whereby the attackers call a victim and attempt to convince their target that they need to do something which will lead to the exposure of financial information while pressuring the victim to think if they don’t act quickly that they will miss an opportunity for personal gain.
Unfortunately, the aforementioned scams really bring in a lot of return for the criminal element. In 2021, over 92,000 victims over the age of 60 reported losses of $1.7 billion. This represents a 74 percent increase in losses over losses reported in 2020.
One additional scam that plays on the heart strings is the romance scams. A lot of single people find themselves lonely during the holidays and can be manipulated into thinking that they’ve found a romantic match. But this can drain the bank accounts as well.
In 2021, the IC3 received reports from 7,658 victims who experienced over $432 million in losses to Confidence Fraud/Romance scams. This type of fraud accounts for the highest losses reported by victims over the age of 60.
All these attacks prey on people’s emotional responses. So, how do we prepare ourselves? We need to make knowledge a capability and arm ourselves with information that will help us avoid being taken advantage of by criminals.
Passwords are a significant exposure. They are the digital equivalent of a house key. A password will work for anyone that has access to it. We need to utilize technologies such as multi-factor authentication (MFA) on websites where it is possible to do so. So even if bad actors have our password, the victim still needs to approve the login.
If we don’t have the option to use MFA it would be an excellent idea to make use of a password manager. This is a way to safely store passwords and not fall into the trap of reusing passwords on multiple sites. Attackers bank on human nature and if we use the same credentials on multiple sites there is a high possibility that the criminals could gain access to other sites if they compromise just one.
I’m usually one to eschew the practice of New Year’s resolutions but I’ll make an exception. Keep a keen sense about yourselves whenever you receive an email or SMS that you were not expecting. If a deal is too good to be true then, well, it most likely is a scam. If you’re in doubt, try to look up the phone number, email address, person or “organization” offering the “deal.” More often than not, you’ll find lots of people reporting that it’s a scam.
Rather than being visited by the three ghosts of holiday scams, make sure you and your loved ones are prepared for a happy holiday and a prosperous New Year.

A recent scoop by Reuters revealed that mobile apps for the U.S. Army and the Centers for Disease Control and Prevention (CDC) were integrating software that sends visitor data to a Russian company called Pushwoosh, which claims to be based in the United States. But that story omitted an important historical detail about Pushwoosh: In 2013, one of its developers admitted to authoring the Pincer Trojan, malware designed to surreptitiously intercept and forward text messages from Android mobile devices.
Pushwoosh says it is a U.S. based company that provides code for software developers to profile smartphone app users based on their online activity, allowing them to send tailor-made notifications. But a recent investigation by Reuters raised questions about the company’s real location and truthfulness.
The Army told Reuters it removed an app containing Pushwoosh in March, citing “security concerns.” The Army app was used by soldiers at one of the nation’s main combat training bases.
Reuters said the CDC likewise recently removed Pushwoosh code from its app over security concerns, after reporters informed the agency Pushwoosh was not based in the Washington D.C. area — as the company had represented — but was instead operated from Novosibirsk, Russia.
Pushwoosh’s software also was found in apps for “a wide array of international companies, influential nonprofits and government agencies from global consumer goods company Unilever and the Union of European Football Associations (UEFA) to the politically powerful U.S. gun lobby, the National Rifle Association (NRA), and Britain’s Labour Party.”
The company’s founder Max Konev told Reuters Pushwoosh “has no connection with the Russian government of any kind” and that it stores its data in the United States and Germany.
But Reuters found that while Pushwoosh’s social media and U.S. regulatory filings present it as a U.S. company based variously in California, Maryland and Washington, D.C., the company’s employees are located in Novosibirsk, Russia.
Reuters also learned that the company’s address in California does not exist, and that two LinkedIn accounts for Pushwoosh employees in Washington, D.C. were fake.
“Pushwoosh never mentioned it was Russian-based in eight annual filings in the U.S. state of Delaware, where it is registered, an omission which could violate state law,” Reuters reported.
Pushwoosh admitted the LinkedIn profiles were fake, but said they were created by a marketing firm to drum up business for the company — not misrepresent its location.
Pushwoosh told Reuters it used addresses in the Washington, D.C. area to “receive business correspondence” during the coronavirus pandemic. A review of the Pushwoosh founder’s online presence via Constella Intelligence shows his Pushwoosh email address was tied to a phone number in Washington, D.C. that was also connected to email addresses and account profiles for over a dozen other Pushwoosh employees.
Pushwoosh was incorporated in Novosibirsk, Russia in 2016.
The dust-up over Pushwoosh came in part from data gathered by Zach Edwards, a security researcher who until recently worked for the Internet Safety Labs, a nonprofit organization that funds research into online threats.
Edwards said Pushwoosh began as Arello-Mobile, and for several years the two co-branded — appearing side by side at various technology expos. Around 2016, he said, the two companies both started using the Pushwoosh name.
A search on Pushwoosh’s code base shows that one of the company’s longtime developers is a 41-year-old from Novosibirsk named Yuri Shmakov. In 2013, KrebsOnSecurity interviewed Shmakov for the story, “Who Wrote the Pincer Android Trojan?” wherein Shmakov acknowledged writing the malware as a freelance project.
Shmakov told me that, based on the client’s specifications, he suspected it might ultimately be put to nefarious uses. Even so, he completed the job and signed his work by including his nickname in the app’s code.
“I was working on this app for some months, and I was hoping that it would be really helpful,” Shmakov wrote. “[The] idea of this app is that you can set it up as a spam filter…block some calls and SMS remotely, from a Web service. I hoped that this will be [some kind of] blacklist, with logging about blocked [messages/calls]. But of course, I understood that client [did] not really want this.”
Shmakov did not respond to requests for comment. His LinkedIn profile says he stopped working for Arello Mobile in 2016, and that he currently is employed full-time as the Android team leader at an online betting company.
In a blog post responding to the Reuters story, Pushwoosh said it is a privately held company incorporated under the state laws of Delaware, USA, and that Pushwoosh Inc. was never owned by any company registered in the Russian Federation.
“Pushwoosh Inc. used to outsource development parts of the product to the Russian company in Novosibirsk, mentioned in the article,” the company said. “However, in February 2022, Pushwoosh Inc. terminated the contract.”
However, Edwards noted that dozens of developer subdomains on Pushwoosh’s main domain still point to JSC Avantel, an Internet provider based in Novosibirsk, Russia.
Edwards said the U.S. Army’s app had a custom Pushwoosh configuration that did not appear on any other customer implementation.
“It had an extremely custom setup that existed nowhere else,” Edwards said. “Originally, it was an in-app Web browser, where it integrated a Pushwoosh javascript so that any time a user clicked on links, data went out to Pushwoosh and they could push back whatever they wanted through the in-app browser.”
An Army Times article published the day after the Reuters story ran said at least 1,000 people downloaded the app, which “delivered updates for troops at the National Training Center on Fort Irwin, Calif., a critical waypoint for deploying units to test their battlefield prowess before heading overseas.”
In April 2022, roughly 4,500 Army personnel converged on the National Training Center for a war games exercise on how to use lessons learned from Russia’s war against Ukraine to prepare for future fights against a major adversary such as Russia or China.
Edwards said despite Pushwoosh’s many prevarications, the company’s software doesn’t appear to have done anything untoward to its customers or users.
“Nothing they did has been seen to be malicious,” he said. “Other than completely lying about where they are, where their data is being hosted, and where they have infrastructure.”
Edwards also found Pushwoosh’s technology embedded in nearly two dozen mobile apps that were sold to cities and towns across Illinois as a way to help citizens access general information about their local communities and officials.
The Illinois apps that bundled Pushwoosh’s technology were produced by a company called Government 311, which is owned by Bill McCarty, the current director of the Springfield Office of Budget and Management. A 2014 story in The State Journal-Register said Gov 311’s pricing was based on population, and that the app would cost around $2,500 per year for a city with approximately 25,000 people.
McCarty told KrebsOnSecurity that his company stopped using Pushwoosh “years ago,” and that it now relies on its own technology to provide push notifications through its 311 apps.
But Edwards found some of the 311 apps still try to phone home to Pushwoosh, such as the 311 app for Riverton, Ill.
“Riverton ceased being a client several years ago, which [is] probably why their app was never updated to change out Pushwoosh,” McCarty explained. “We are in the process of updating all client apps and a website refresh. As part of that, old unused apps like Riverton 311 will be deleted.”
Edwards said it’s far from clear how many other state and local government apps and Web sites rely on technology that sends user data to U.S. adversaries overseas. In July, Congress introduced an amended version of the Intelligence Authorization Act for 2023, which included a new section focusing on data drawn from online ad auctions that could be used to geolocate individuals or gain other information about them.
Business Insider reports that if this section makes it into the final version — which the Senate also has to pass — the Office for the Director of National Intelligence (ODNI) will have 60 days after the Act becomes law to produce a risk assessment. The assessment will look into “the counterintelligence risks of, and the exposure of intelligence community personnel to, tracking by foreign adversaries through advertising technology data,” the Act states.
Edwards says he’s hoping those changes pass, because what he found with Pushwoosh is likely just a drop in a bucket.
“I’m hoping that Congress acts on that,” he said. “If they were to put a requirement that there’s an annual audit of risks from foreign ad tech, that would at least force people to identify and document those connections.”
Welcome back! In our last article, you cleared out your extraneous digital footprints by removing unnecessary accounts and opting-out of data broker services, and have finished a dedicated review of your online history. In this final section, we will answer the natural question encountered at the end of any journey: What’s next?
Before becoming the series you’ve just read, I presented a version of this many times as a live talk at conferences and training sessions. After the first few talks, I noticed a consistent trend in the feedback when I was approached afterwards: people who said they felt anxious about how their online activity going forward might share more than they want. So I went back and added a final section to the talk, one that we’re going to cover together now: risk acceptance and the value of routine in good security.
Some people think that the goal of good security is to eliminate risk. One of the first lessons you learn in this industry, though, is that eradicating every possible risk is very rarely practical, whether we’re talking about the individual or organizational level. This is because there are few choices one can make with zero possibility of a negative outcome, and because human beings are… human, and even with excellent discipline and good intent the best of us can mess up.
The goal of good security strategy is instead to assess risk and find a healthy balance: to decide what is more or less important and valuable, to determine how damaging the worst-case scenario might be and weigh that against the potential benefits, and figuring out how much you can reasonably do to tip the balance and increase your odds of success.
That’s fairly abstract, so let’s use a couple quick practical examples at both levels:
I don’t know about you, but I grew up as a child of the internet, and the thought of never going online again isn’t one I’m likely to seriously consider. So rather than logging off forever, let’s focus on how we can both stay safe and stay connected. We’ve completed the “3 R’s” of the self-dox process: Review, Restrict, and Remove. But now, a surprise more shocking than the Spanish Inquisition itself: we’re going to add two final steps-Repeat and Refine.
Every good security plan includes a plan for routine follow-up. We know that staying offline forever isn’t practical, so the next best thing is to set up a reminder to go through an easier version of this checklist on a regular schedule. Why is it easier? In this review, you had to look back on your entire life up to the present, and next time you’ll just need to look back from then to… well… now! Depending on how active you are online and how likely you are to be doxxed, this might make sense to do on an annual basis, or split into abbreviated and more frequent quarterly reviews.
There is no one-size-fits-all approach to this review, but here are some typical checks you may want to consider:
Before we move on to our final (final, I promise!) step, let’s talk one more kind of repeating. A wifi repeater is a gadget that can connect to and boost the signal from a wireless network, helping to expand the network’s reach and keep a strong connection. In the same way, by sharing the lessons you’ve learned with your family and friends you will expand the reach of that security knowledge. Not only does that help keep the people you care about safer… but since we’ve seen how information shared about us by others can also be discovered by doxxers, it helps to increase your own safety as well!
My goal in writing this series was to give a straightforward introduction and broadly-useful walkthrough of how to figure out what’s out there about you online. In the beginning of this series, I talked about how the level of risk for doxxing is not the same for everyone. You may want to go significantly further than we’ve covered in this guide if you are:
This can cover a wide range of additional steps like placing a freeze on your credit report, requesting a privacy removal from search engines, or even setting up dedicated secure devices/apps for communication online. The full scope of these additional protections is beyond what we can cover here, but I will again recommend the Self-Doxxing Guide from AccessNow and the Gender and Tech Safety Resource guide linked in the first post of this series as an excellent reference for where else you might want to check.
Thank you for following along with me on this journey, and I hope that you found this guide and the resources shared have been helpful for you. Still have questions, or have you discovered any of the links/tools here are no longer available? Please let me know! Life comes at you fast on the web, and I want to make sure this guide continues to be relevant and helpful for a long time to come. You can drop me a line at zoe@duo.com, or find me on Twitter. Until then, happy trails and stay safe out there!

Previously in our Go Dox Yourself series, we walked through reviewing what information is available about you online, prioritizing those accounts that are most important or still active, and then restricting how much we share through those accounts and who gets to see it. That’s two out of our three steps — maybe good enough for Meatloaf, but not for us! You’re in the home stretch now, and this is the most straightforward-if-slow portion of the process — so let’s dive right in.
In the review step , along with the top accounts that you wrote out in your initial brain dump, we used some email search tricks and the free services NameCheckup.com and NameChk.com to dig up any unused, forgotten, or now obsolete accounts you might have previously registered under your email address or favorite username (or, as us ʼ80s kids used to say, your “handle.”)
We set those old accounts to the side to focus on your active and sensitive data first, but now it’s time to make Marie Kondo proud and clean out the junk drawers of our online life – if it doesn’t still serve you or spark joy, let’s kiss it goodbye!
In a perfect world, this would be as simple as logging in, going to your account settings and clicking a big ol’ “Cancel My Account” button. However, many sites opt to bury the cancelation settings behind a series of smokescreen menus, sometimes even including a half dozen unskippable “are you SURE you want to leave?” and “but we’ll give you a super good deal to stay!” surveys to click through first.
If you find yourself thwarted and your first search of “[Unwanted Service] cancel” doesn’t take you where you need to go, try checking out AccountKiller. This collaborative resource takes submissions of step-by-step deletion instructions and direct links to cancel for a tremendous number of sites, and even includes phone tree options and direct support numbers for canceling offline accounts as well.
The first pass of your delete list might well be longer than a CVS receipt, because these days the average person has 100 password-protected accounts to manage, but don’t worry! You don’t have to sprint to the finish line, and slow progress checking off a few accounts in short sessions over a few weeks will serve you better than a several-hour slog of trying to clear them all at once and burning out.
An important lesson in security is that operating at max capacity isn’t sustainable all the time, and planning for rest and overflow in our personal security planning is no different. Remember that the work you’re doing is cumulative, each small step is one more forward, and every account you clear now is one less that you’ll need to revisit later.
You might notice that we’ve checked off most of the information from our initial brainstorm: emails, usernames, phone numbers, profile pictures… but so far, we haven’t done much with your location history: the cities you lived in and live now, the cities where you worked or went to school, and the city of your birth. Now that we’re going to see how much information on you is available through data brokers and public record sites, these details will be important to have handy.
For the unfamiliar, data brokers are companies which collect and bundle personal information for everything from ad customization to individual investigation. Brokers collect their data through a wide variety of methods, including:
These metrics and details are bundled and sold, either directly through lookup sites like we’ll review in just a moment, or in demographic bundles (for example, “Resilient Renters” or “Living on Loans: Young Urban Single Parents”). If you’ve ever walked through a car dealership window-shopping and suddenly found sponsored content for that car company in your feed, data brokers are the most likely reason.
For this step you should reference the previously-mentioned Personal Data Removal Workbook provided by Michael Bazzell through his company, IntelTechniques. Bazzell has maintained and updated this workbook for many years now, and it is by far the most comprehensive resource for keeping a handle on who is buying and selling your data.
One of the first things you’ll notice on opening the workbook is the sheer volume of businesses out there buying and selling your data: at time of writing, the current edition includes 220 separate brokers. But much like your initial account inventory likely included a select set of important accounts and a longer list of less-relevant ones, there are less than a dozen brokers who dominate most of the market and should be at the top of your list – and fortunately, they’re also at the top of the workbook! These sites are:
Aside from covering most of the market for data and analytics intelligence, these primary sites often act as “feeders” for smaller providers that are either directly affiliated or collect information for their own databases from the largest providers. Which means that as you remove your data from these sites, you’ll not only check off another box on your list, but you may also reduce the number of hits you find for your information on smaller sites as you work your way down.
Congratulations: if you’ve been following along, you’ve just made it through your self-doxxing! Hopefully you’re feeling much better informed and aware of what tracks you’ve left online, and addressed who you do and do not want to have your… addresses. Join us soon for our wrap-up post where we’ll recap with takeaway lessons, as well as good habits and check-ins to keep you safe going forward.

With passwords and MFA out of the way, let’s next look at connected apps or services that are tied to our priority accounts. When you log into other sites on the web through Facebook, Google, or another social account, as well as when you install social media apps or games, you are sharing information about those accounts with those services. This may be as limited as the email address and username on file, or may include much more information like your friends list, contacts, likes/subscriptions, or more.
A well-known example of this data-harvesting method is the Cambridge Analytica story, where installing a social media app opened up access to much more information than users realized. (Note: as mentioned in the linked article, Facebook added protective measures to limit the amount of data available to app developers, but connected accounts can still present a liability if misused.)
With this in mind, look under the Security or Privacy section of each of your account’s settings, and review where you have either used this account to log into a third-party website or allowed access when installing an app. Here are some handy links to some of the most common services to check:
If you aren’t going to use the app again or don’t want to share any details, remove them. Once you’ve checked your accounts, repeat this process with all the apps installed on your phone.
Just like connecting a social account to a third-party game can share information like your contact info and friend’s list, installing an app on your mobile device can share information including your contacts, camera roll and more. Fortunately, mobile OSes have gotten much better at notifying users before installation on what information is shared, so you should be able to see which apps might be nosier than you’re comfortable with.
Finally — and this is really for the nerds and techies out there — check if you have any API (short for “application programming interface”) keys or browser extensions connected to your accounts. API keys are commonly used to let different apps or services “talk” between one another. They let you use services like Zapier or IFTTT to do things like have your Spotify favorites automatically saved to a Google Sheet, or check Weather Underground to send a daily email with the forecast.
Browser extensions let you customize a web browser and integrate services, like quickly clicking to save an article for review on a “read it later” service like Instapaper. Even if you trust the developer when installing these apps, they may pose a risk later on if they are recovered or taken over by an attacker. These “zombie extensions” rely on a broad install base from a legitimate service which can later be misused to gather information or launch attacks by a malicious developer.
We’ve made great progress already, and taken steps to help defend your accounts from prying eyes going forward – now it’s time to lock down your previous activities on social media. Rather than enumerate every option on every service, I’ll highlight some common tools and privacy settings you’ll want to check:
Before moving on to email, I’ll add another plug for the NYT Social Media Security and Privacy Checklists if you, like me, would rather have a series of boxes to mark off while going through each step above.
Security experts know that you can’t erase the possibility of risk, and it can be counterproductive to build a plan to that expectation. What is realistic and achievable is identifying risk so you know what you’re up against, mitigating risk by following security best practices, and isolating risk where possible so that in the event of an incident, one failure doesn’t have a domino effect affecting other resources. If that seems a bit abstract, let’s take a look at a practical example.
Tech journalist Mat Honan was the unlucky victim of a targeted hack, which resulted in a near-complete lockout from his digital life requiring a Herculean effort to recover. Fortunately for us, Mat documented his experience in the Wired story, “How Apple and Amazon Security Flaws Led to My Epic Hacking,” which offers an excellent summary of exactly the type of domino effect I described. I encourage you to read the full article, but for a CliffsNotes version sufficient for our needs here:
Honan’s article goes into much more detail, including some of the changes made by the services exploited to prevent similar incidents in the future. The key takeaway is that having a couple of emails without strong authentication tied to all his most important accounts, including the recovery of these email accounts themselves, meant that the compromise of his Amazon account quickly snowballed into something much bigger.
We’re going to learn from that painful lesson, and do some segmentation on our email channels based on the priority and how public we want that account to be. (“Segmentation” is an industry term that can be mostly boiled down to “don’t put all your eggs in one basket”, and keep critical or vulnerable resources separate from each other.) I would suggest setting up a few different emails, listed here from least- to most-public:
For all of the above, of course, we’ll create strong passwords and set up 2FA. And speaking of 2FA, you can use the same split-channel approach we followed for email to set up a dedicated verification number (using a VOIP service or something like Google Voice) when sending a passcode by SMS is the only option supported. Keeping these recovery numbers separate from your main phone number reduces the risk of them being leaked, sold, or captured in an unrelated breach.
Good news: We’re almost done with doxxing ourselves! In the next section, we’ll sweep out those unused accounts to avoid leaving data-filled loose ends and take a look at how data brokers profit off of your personal information and what you can do to opt-out.
You’ve made it this far so maybe you’re passionate like we are about developing innovative ways to make security accessible. We’d love for you to join our mission.

In the first step of our doxxing research, we collected a list of our online footprint, digging out the most important accounts that you want to protect and obsolete or forgotten accounts you no longer use. Because the most recent and relevant data is likely to live in the accounts you use regularly, our next step will be to review the full scope of what’s visible from these accounts and to set more intentional boundaries on what is shared.
It’s important to note here that the goal isn’t to eliminate every trace of yourself from the internet and never go online again. That’s not realistic for the vast majority of people in our connected world (and I don’t know about you, but even if it was I wouldn’t want to!) And whether it’s planning for an individual or a giant organization, security built to an impossible standard is destined to fail. Instead, we are shifting you from default to intentional sharing, and improving visibility and control over what you do want to share.
Before making changes to the settings and permissions for each of these accounts, we’re going to make sure that access to the account itself is secure. You can start with your email accounts (especially any that you use as a recovery email for forgotten passwords, or use for financial, medical, or other sensitive communications). This shouldn’t take very long for each site, and involves a few straightforward steps:
The best way to prevent a breached password from exposing another account to attack is to use a unique password for for every website you visit. And while you may have heard previous advice on strong passwords (along the lines of “eight or more characters, with a mix of upper/lower case letters, numbers, and special characters”), more recent standards emphasize the importance of longer passwords. For a great explanation of why longer passwords work better than shorter, multi-character type passwords, check out this excellent XKCD strip:
A password manager will make this process much easier, as most have the ability to generate unique passwords and allow you to tailor their length and complexity. While we’re on the topic of what makes a good password, make sure that the password to access your password manager is both long and memorable.
You don’t want to save or auto-fill that password because it acts as the “keys to the kingdom” for everything else, so I recommend following a process like the one outlined in the comic above, or another mnemonic device, to help you remember that password. Once you’ve reset the password, check for a “log out of active devices” option to make sure the new password is used.
MFA uses two or more “factors” verifying something you know, something you have, or something you are. A password is an example of “something you know”, and here are a few of the most common methods used for an additional layer of security:
If you want to know more about the different ways you can log in with strong authentication and how they vary in effectiveness, check out the Google Security Team blog post “Understanding the Root Cause of Account Takeover.”
Before we move on from passwords and 2FA, I want to highlight a second step to log in that doesn’t meet the standard of strong authentication: password questions. These are usually either a secondary prompt after entering username and password, or used to verify your identity before sending a password reset link. The problem is that many of the most commonly-used questions rely on semi-public information and, like passcodes, are entered on the same device used to log in.
Another common practice is leveraging common social media quizzes/questionnaires that people post on their social media account. If you’ve seen your friends post their “stage name” by taking the name of their first pet and the street they grew up on, you may notice that’s a combination of two pretty common password questions! While not a very targeted or precise method of attack, the casual sharing of these surveys can have consequences beyond their momentary diversion.
One of the first widely-publicized doxxings happened when Paris Hilton’s contact list, notes, and photos were accessed by resetting her password using the password question, “what is your favorite pet’s name?”. Because Hilton had previously discussed her beloved chihuahua, Tinkerbell, the attacker was able to use this information to access the account.
Sometimes, though, you’ll be required to use these password questions, and in those cases I’ve got a simple rule to keep you safe: lie! That’s right, you won’t be punished if you fib when entering the answers to your password questions so that the answers can’t be researched, and most password managers also include a secure note field that will let you save your questions and answers in case you need to recall them later.

Sharing is caring… but on the internet, sharing can also be tricky! When we post something, we have to look at the forest and not just the trees. Doxxers usually start with one or two pieces of relatively innocent or public information, but by connecting the dots between those pieces they can build a frighteningly detailed picture of an individual.
Seemingly innocuous details can be pieced together into a much more personal profile when collected and leveraged to learn more. As one example, your wish list/wedding registry makes it easy for friends and family to get you gifts that you actually want, but could also be used to find out products/services you’re interested in as pretext (setting the scene) of a conversation or phishing email trying to gather more. You may have Google Alerts set up for your name (a great idea!), but this may not flag text in scanned documents such as school yearbooks, newspapers and other digitized paper records available online.
If the above sounds scary – don’t panic! Your first step in this auto-dox is going to be brainstorming as much personally identifying information (PII) shared online as possible. I suggest doing this either in a secure note or longhand. The goal is to write down all of the accounts/addresses/phone numbers that come to mind, as these are some of the top things that attackers will try to gather in their search. Start your list here:
Email addresses are an especially juicy target for someone trying to locate you, because most people only use one personal and maaaybe a second school or work email account. Those accounts are tied to all our other online identities and often double as our username for logging in.
When you finish this process, you will likely have dozens or even hundreds of “breadcrumbs” between your account list and search results. Read through your list again, and we’re going to sort it into three categories:
Great job! You’ve already got a much better idea of what people can learn about you than most folks ever do, and are well on your way to cleaning up your online footprint. In our next step, we’ll start locking down everything that you want to keep!

Whether or not you’ve heard the term “doxxing” before, you’re probably familiar with the problem it names: collecting personal information about someone online to track down and reveal their real-life identity. The motivations for doxxing are many, and mostly malicious: for some doxxers, the goal in tracking someone is identity theft. For others, it’s part of a pattern of stalking or online harassment to intimidate, silence or punish their victim – and overwhelmingly, victims are youth and young adults, women, and LGBTQ+ people. The truth is, most of us have information online that we don’t realize can put us at risk, and that’s why I’ve written this series: to inform readers about how doxxing happens, and how you can protect yourself from this very real and growing problem by doxxing yourself.
In computer security, we talk about the idea of a “security mindset”: understanding how someone with bad intentions would cause harm, and being able to think like they would to find weak spots. In this series, you will learn by doing. By understanding the tools and methods used by those with ill intent, you’ll be better prepared to keep yourself safe and your information secure.
Your mission, should you choose to accept it, is to follow along and find out everything the internet knows about… you!
This series will provide simple steps for you to follow as you begin your investigation. Along the way, as you get familiar with the tools and tactics of internet sleuths, you’ll get a better idea of your current internet footprint as well as know what tracks you leave in the future. Our process will be split into three main sections:
Information is power. And in the case of doxxing, most people don’t realize how much of their power they’re giving up! My goal in this series is to demystify the methods used for doxxing, so in the spirit of “showing my work,” here are some of the best resources and collected checklists I referenced when planning these exercises, along with how to best use each:
If this looks like a whole lot of homework… don’t worry! We’ll cover most of the core tools and tips mentioned in these resources through the course of this series, and we’ll revisit these links at the end of the series when you’ve gotten more context on what they cover. In the next article, we’ll take on the review step of our process, getting a holistic inventory of what personal information is currently available online so you can prioritize the most important fixes. See you soon!

Password protection is one of the most common security protocols available. By creating a unique password, you are both proving your identity and keeping your personal information safer. However, when every account you have requires a separate password, it can be an overwhelming task. While you should be concerned about the safety of your data, you also want to avoid the frustration of forgetting your password and being blocked from the information you need. However, the benefits of using strong, unique passwords outweigh the occasional inconvenience.
The main benefit of a strong password is security. Hackers work quickly when they are trying to access accounts. They want to steal as much information as they can in as short a time as possible. This makes an account with a strong password less inviting because cracking the code is much more involved.
A strong password also limits the damage that hackers can do to your personal accounts. A common strategy involves cracking the passwords of less secure sites with limited personal information. The hackers hope that they can use the password from your gym membership app to access information in your online banking account. Strong password protection prevents this situation.
When someone is registering an online account, it can be tempting to blaze through the password process. In order to move quickly, there are several poor password practices that people employ.
A password is considered strong when it is difficult for a hacker to crack it quickly. Sophisticated algorithms can run through many password combinations in a short time. A password that is long, complex and unique will discourage attempts to break into your accounts.
If you want a password that is memorable but strong, you can easily turn a phrase into a layered, complex password. In this process, it is important to note that you should not use personal information that is available online as part of your phrase.
Now, you have a password that you can remember while challenging the algorithms hackers use.
When you consider the number of accounts you need to protect, coming up with a properly layered password is a time-consuming task. Even if you are able to decide on a memorable phrase, there are just too many accounts that need passwords. A password manager is a helpful tool to keep you safe while you are online. It acts as a database for all of your passwords. Each time you create a new code, it stores it so that you can automatically enter it later. You only need to remember a single password to access the tools of your manager.
Most managers can also do the work of creating complex, layered passwords for your accounts. These will be a string of random numbers, letters and characters. They will not be memorable, but you are relying on the manager to do the memorizing. These machine-generated passwords are especially helpful for accounts you rarely access or that do not hold significant information.
For critical accounts like your bank account or a work-related account, it can be helpful to keep an offline list of your passwords. Complex passwords are meant to be difficult to remember. You may recall the phrase but not all the detailed changes that make it layered. Keeping a document on a zip drive or even in a physical paper file or journal will allow you to access your information if your hardware fails or you are switching to a new system.
Cracking passwords is just one of the strategies hackers use to steal information. In addition to using strong passwords, it is important to employ comprehensive security software. Strong passwords will help protect your online accounts. Strong overall security will keep your hardware and network safe from danger.
The post Strong Password Ideas to Keep Your Information Safe appeared first on McAfee Blog.
Here’s one way you can help reduce your chances of identity theft: remove your personal information from the internet.
And chances are, you have more personal information posted online than you think.
According to the U.S. Federal Trade Commission (FTC), consumers registered 1.4 million identity theft complaints in 2021, all part of a year where consumers reported losing $5.8 billion to fraud overall—a 70% increase over the year prior.
What fuels all this theft and fraud? Access to personal information.
Scammers and thieves can get a hold of personal information in several ways, such as through phishing attacks that lure you into handing it over, malware that steals it from your devices, by purchasing your information on dark web marketplaces, or as a result of information leaked in data breaches, just to name a few.
However, scammers and thieves have other resources to help them commit theft and fraud—data broker sites, places where personal information is posted online for practically anyone to see. Which makes removing your info from them so important, from both an identity and privacy standpoint.
Think of data broker sites as huge repositories of personal information. Search your name and address online and you’ll see. You’ll likely find dozens of sites that turn up information about you, some of which offer a few pieces for free and others that offer far more information for a price.
Data brokers collect and then aggregate personal information from several sources, including:
Data brokers also buy personal information from other data brokers. As a result, some data brokers have thousands of pieces of data for billions of individuals worldwide.
What could that look like? A broker may know how much you paid for your home, your education level, where you’ve lived over the years and who your lived with, your driving record, and possibly your political leanings. A broker may also know your favorite flavor of ice cream and your preferred over-the-counter allergy medicine thanks to information from loyalty cards. Further, they may also have health-related information from fitness apps. The amount of personal information can run that broadly, and that deeply.
With information at this potential level of detail, it’s no wonder that data brokers rake in an estimated at $200 billion U.S. dollars worldwide every year.
On the legitimate side, it’s used by advertisers to create targeted ad campaigns. With information sold by data brokers, they can generate lists based on highly specific criteria, such as shopping histories, personal interests, and even political leanings as mentioned above. Likely without you being aware of it—and likely with no way to contest that information if it’s incorrect.
Other legitimate uses include using these sites for background checks. Law enforcement, reporters, and employers will use data brokers as a starting point for research because the leg work has largely been done for them. Namely, data brokers have aggregated a person’s information already, which is an otherwise time-consuming process.
If this seems a little shady, it’s still legal. As of now, the U.S. has no federal laws that regulate data brokers or require data them to remove personal information if requested. A few states, such as Nevada, Vermont, and California, have legislation in place aimed at protecting consumers. Meanwhile, the General Data Protection Regulation (GDPR) in the European Union has stricter rules about what information can be collected and what can be done with it. Still, the data broker economy thrives.
On the darker side, scammers and thieves use personal information for identity theft and fraud. With enough personal information gathered from enough sources, they can create a high-fidelity profile of their victims. One that gives them enough information to open new accounts in their name.
So, from the standpoint of both privacy and identity, cleaning up your personal information online makes a great deal of sense.
Let’s review some ways you can remove your personal information from data brokers and other sources on the internet.
The process starts with finding the sites that have your information. From there, you can request to have it removed. Yet as mentioned above, there are dozens and dozens of these sites. Knowing where to start is a challenge in of itself, as is manually making the requests once you have identified the sites that post and sell information about you.
Our Personal Data Cleanup can do the work for you. Personal Data Cleanup scans some of the riskiest data broker sites and shows you which ones are selling your personal info. It also provides guidance on how you can remove your data from those sites and can even manage the removal for you depending on your plan. It also monitors those sites, so if your info gets posted again, you can request its removal again.
As of September 2022, Google accounts for just over 92% of search engine market share worldwide. Aside from being a search engine, Google offers a myriad of other services and applications, such as Gmail and Google Maps. While Google offers plenty of tools for productivity, travel, work, and play for free, they still come at a cost—the gathering and analysis of your personal information.
You can limit the data Google associates with you by removing your name from Google search results with a removal request. This will disable anyone online from getting any results if they search your name. (Note that this will not remove your information from the original sites and sources where it’s posted.) Moreover, Google collects all your browsing data continuously. You have the option to turn on “Auto Delete” in your privacy settings to ensure that the data is deleted regularly and help limit the amount of time your sensitive data stays vulnerable.
You can also occasionally delete your cookies or use your browser in incognito mode to prevent websites from being tracked back to you. Go to your Google Chrome settings to clear your browser and cookie history.
As discussed above, data brokers can collect information from public social media profiles. You can minimize your presence on social media to the bare minimum. Make a list of the ones you use or have used in the past. If there are old accounts that you no longer use or websites that have gone by the wayside like Myspace or Tumblr, you may want to deactivate them or consider deleting them entirely.
For social media platforms that you still may use regularly, like Facebook and Instagram, consider adjusting your privacy settings to ensure that your personal information on these social media platforms is the bare minimum. For example, on Facebook you can lock your profile, while on Instagram you can stay private.
If you’ve ever published articles, written blogs, or created any content online, it might be a good time to consider taking it down if it is no longer serving a purpose. Depending on what you’ve posted, you may have shared personal details about your life. Additionally, you might be mentioned by other people in various social media posts, articles, or blogs. It is worth reaching out to these people to request them to take down posts with sensitive information.
Social media and online articles that host your personal information are often used when businesses or hackers are doing “internet scrapes” to find better ways to use your targeted information. Asking your friends or third-party sites to remove that information can help protect your privacy.
Another way you can tidy up your digital footprint online involves deleting all the unnecessary phone apps that you no longer need or use. Even when apps are not open or in use, they may be able to track personal information such as your real-time location and even your payment details if you have a paid subscription to the app.
Some apps even sell this data as it can be extremely advantageous to other companies, which they use to target certain consumer segments and profiles for advertising. Try to share as little information with apps as possible if you’re looking to minimize your online footprint, and provide them access to your photos, contacts, and location only on as-needed basis and only when the app is in use. Your phone’s app and location services settings will give you the tools to do it.
In addition to the steps above, comprehensive online protection software can keep you more private and minimize your risk of cybercrime. It can include:
So while it may seem like all this rampant collecting and selling of personal information is out of your hands, there’s plenty you can do to take control. With the steps outlined above and strong online protection software at your back, you can keep your personal information more private and secure.
The post 5 Steps to Removing Your Personal Information From the Internet appeared first on McAfee Blog.
Our personal and professional lives are becoming increasingly intertwined with the online world. Regular internet usage has made us all prone to cyber-security risks. You leave a digital footprint every time you use the internet, which is a trace of all your online activities.
When you create new accounts or subscribe to different websites, you give them explicit (or implicit, through their family of apps or subsidiary websites) access to your personal and credit card information. In other cases, websites might track basic information without your knowledge, such as your location and search history.
There is an industry of data brokers specifically dedicated to keeping track of user data, packaging it, and supplying it to tech companies who use it to run targeted ads and enhance on-platform user experience. Given the widespread use of the internet and exponential improvements in technology, data has become a valuable commodity — creating a need for the sale and purchase of user data.
This article discusses how data brokers sell your personal information and how you can minimize risk.
Data brokers are companies that aggregate user information from various sources on the internet. They collect, collate, package, and sometimes even analyze this data to create a holistic and coherent version of you online. This data is then supplied to tech companies to fuel their third-party advertising-centered business models.
Companies interested in buying data include but are not limited to:
These companies and social media platforms use your data to better understand target demographics and the content with which they interact. While the practice isn’t unethical in and of itself (personalizing user experiences and creating more convenient UIs are usually cited as the primary reasons for it), it does make your data vulnerable to malicious attacks targeted toward big-tech servers.
Most of your online activities are related. Devices like your phone, laptop, tablets, and even fitness watches are linked to each other. Moreover, you might use one email ID for various accounts and subscriptions. This online interconnectedness makes it easier for data brokers to create a cohesive user profile.
Mobile phone apps are the most common way for data brokerage firms to collect your data. You might have countless apps for various purposes, such as financial transactions, health and fitness, or social media.
A number of these apps usually fall under the umbrella of the same or subsidiary family of apps, all of which work toward collecting and supplying data to big tech platforms. Programs like Google’s AdSense make it easier for developers to monetize their apps in exchange for the user information they collect.
Data brokers also collect data points like your home address, full name, Social Security number, phone number, and date of birth. They have automated scraping tools to quickly collect relevant information from public profiles.[Text Wrapping Break]
Lastly, data brokers can gather data from other third parties that track your cookies or even place trackers or cookies on your browsers. Cookies are small data files that track your online activities when visiting different websites. They track your IP address and browsing history, which third parties can exploit. Cookies are also the reason you see personalized ads and products.
Data brokers collate your private information into one package and sell it to “people search” websites like Spokeo or TruePeopleSearch. You or a tech business can use these websites to search for people and get extensive consumer data. People search sites also contain public records like voter registration information, marriage records, and birth certificates. This data is used for consumer research and large-scale data analysis.
Next, marketing and sales firms are some of data brokers’ biggest clients. These companies purchase massive data sets from data brokers to research your data profile. They have advanced algorithms to segregate users into various consumer groups and target you specifically. Their predictive algorithms can suggest personalized ads and products to generate higher lead generation and conversation percentages for their clients.
We tend to accept the terms and conditions that various apps ask us to accept without thinking twice or reading the fine print. You probably cannot proceed without letting the app track certain data or giving your personal information. To a certain extent, we trade some of our privacy for convenience. This becomes public information, and apps and data brokers collect, track, and use our data however they please while still complying with the law.
There is no comprehensive privacy law in the U.S. on a federal level. This allows data brokers to collect personal information and condense it into marketing insights. While not all methods of gathering private data are legal, it is difficult to track the activities of data brokers online (especially on the dark web). As technology advances, there are also easier ways to harvest and exploit data.
Vermont and California have already enacted laws to regulate the data brokerage industry. In 2018, Vermont passed the country’s first data broker legislation. This requires data brokers to register annually with the Secretary of State and provide information about their data collection activities, opt-out policies, purchaser credentialing practices, and data breaches.
California has passed similar laws to make data brokering a more transparent industry. For risk mitigation of data brokerage, the Federal Trade Commission (FTC) has published reports and provided recommendations to Congress to reduce the engagement of data broker firms. Giving individuals the right to opt-out of the sale of their personal data is a step toward a more rigorous law regarding data privacy.
Some data brokers let you remove your information from their websites. There are also extensive guides available online that list the method by which you can opt-out of some of the biggest data brokering firms. For example, a guide by Griffin Boyce, the systems administrator at Harvard University’s Berkman Klein Center for Internet and Society, provides detailed information on how to opt-out of a long list of data broker companies.
Acxiom, LLC is one of the largest data brokering firms and has collected data for approximately 68% of people who have an online presence. You can opt-out of their data collection either through their website or by calling them directly.
Epsilon Data Management is another big player in the data broker industry that operates as a marketing service and marketing analytics company. You can opt-out of their website through various methods such as by email, phone, and mail. Credit rating agencies like Experian and Equifax are also notorious for collecting your data. Similarly, you can opt-out through their websites or by calling them.
McAfee is a pioneer in providing online and offline data protection to its customers. We offer numerous cybersecurity services for keeping your information private and secure.
With regard to data brokers, we enable users to do a personal data clean-up. Cleaning up your personal data online may be a difficult task, as it requires you to reach out to multiple data brokers and opt out. Instead, sign up for McAfee’s Personal Data Cleanup feature to do a convenient and thorough personal data clean-up. We will search for traces of your personal data and assist in getting it removed.

World Password Day isn’t the most popular day on the calendar, but it’s an important reminder that good password hygiene is essential to staying safe online. This World Password Day, we’d like to talk about improving your password hygiene, how you can help your friends and family improve theirs, and what the future of authentication holds.
The SolarWinds hack in 2020 is one of the most devastating hacks in the history of the internet. Close to 20,000 company’s systems were compromised, losing billions of pieces of data in the process. If you’re one of the 37% of Americans that go long periods of time without updating passwords*, large-scale attacks like SolarWinds can be devastating. By stealing so many login credentials simultaneously, attackers can potentially access exponentially more accounts by reusing leaked credentials on different sites. Unfortunately this is not an isolated event, data breaches from websites and services we frequently use continue to happen through 2021 as well.
According to a recent survey we conducted, 34% of Americans have reused the same, or similar, password more than once. By using the same password for multiple accounts, attackers only need to find one password, creating a domino effect that makes it easier to access more accounts. If that password is weak, it becomes even easier to tip over that first domino.
Our guidance is to create strong, hard-to-guess passwords to protect your accounts. We recommend creating a unique password for every online account, using more than 16 characters, with upper and lower case letters, some numbers, and special symbols, to make a stronger than average password. How are you supposed to remember all of those strong passwords, though?
Well, password managers, especially those included in comprehensive security suites like McAfee® Total Protection, do much of the heavy lifting for you. For instance, McAfee’s integrated password manager not only helps you create stronger passwords and store them, but will also autofill your credentials and log you into websites as well. These convenient features extend beyond just your computer and can be used on other devices like your phone and tablet. Best of all, password managers that are an integrated part of a security suite can be monitored, so you’ll be alerted if your passwords get exposed in a data breach.
You’ve already taken a step towards improving your password hygiene by reading this blog post. But the next step is, have an honest look at your passwords. Do you write them down, use the same for many accounts, or use weak ones? Then it may be time for a change to better protect your accounts and the personal info in those accounts.
If you’re like a certain member of my family—that will remain nameless, Mom—who kept their passwords written down in a notepad, making the change to a password manager (McAfee’s, naturally) was a life-changing moment. Not only did it help her see just how often she was using the same login credentials, she now has an easy way to store, auto-fill, and even generate strong passwords across all her accounts and devices. An intended bonus was that she also realized how many accounts she was no longer using!
Now that you know more about what makes a strong password and how to protect them, let’s talk about why strong passwords are just the start of keeping your accounts safe. You’re probably already using Two-Factor Authentication for apps and services, but you may not have heard the term before. Two-Factor Authentication, or 2FA, is the second layer of protection to authenticate or prove you are the owner of this account. If you’ve received a text message or an email to confirm a new account signup, that’s a type of 2FA.
Text messages and email aren’t the only types of 2FA. There are USB keys, apps, and even systems built-in to your phone, like facial recognition to open phone apps, for example. Some popular 2FA options are USB keys and Google Authenticator.
The great thing about 2FA is that it helps make your strong passwords even more effective by stopping an attacker from using stolen credentials. If you fell victim to a phishing attack that looked like your bank’s website, the attacker would have your email and password combination. Without 2FA, they could log into your account and pretend they’re you. With 2FA in place, it becomes much harder for an attacker to access your account because they’re missing that last important piece of information.
Humans are almost always the weakest link when it comes to securing information. But by committing ourselves to better password practices, with help from the latest technology, we can make sure passwords are a strong link in our security chain; one that will only get stronger in the future.
For instance, using a device like a key-fob, new passwordless systems can authenticate a user without entering their login details. Not only does this make logging into your accounts lightning fast, you also never have to remember a complicated password again.
Biometric locks, like FaceID, are another example of passwordless entry. Using your face, or a fingerprint to authenticate yourself makes it much harder for attackers to break into your accounts.
We hope this Password Day post has helped answer some questions about password hygiene and how to take better care of your online accounts. Online security changes from day to day, so staying aware of new technologies and building safe new habits is essential. Perhaps one day this day will no longer need to exist on our calendars, as we look to a future where we might not need passwords at all. While we collectively make strikes towards this future, let’s celebrate this day while it lasts.

Video conferencing has really taken off this year. With more people working and learning from home than ever before, video calling has rapidly become the mainstream method for remote communication, allowing users to stay connected. But very few may realize that they might be giving away their passwords on video calls through their body language. According to Tom’s Guide, call participants can guess a user’s passwords through the arm and shoulder movements they make while they type.
Let’s unpack how this threat works so you can continue to connect via video calls worry-free.
Keyboard snooping, or a keyboard interference threat, occurs when an attacker is present on a video call and observes the target’s body and physiological features to infer what they are typing. To pull off this attack, the hacker would need to record the meeting or video stream and feed it through a computer program. This program eliminates the visual background and measures the user’s arm and shoulder movements relative to their face. From there, the program analyzes the user’s actions to guess which keys they are hitting on the keyboard – including passwords and other sensitive information.
So, how accurate is this program, anyway? While this shows that the program was only correct 20% of the time when subjects were on their own devices in an uncontrolled environment, the program’s accuracy increased to 75% if their password was one of the one million most commonly used passwords. And suppose the program already knew their email address or name. In that case, it could decipher when the target was typing this information during the video call (and when their password would immediately follow) 90% of the time. The less complex the target makes their password, the easier it is for the program to guess what they’re typing.
Keystroke inference attacks can have potentially dangerous effects, since the text typed can often contain sensitive or private information even beyond passwords, like credit card numbers, authentication codes, and physical addresses. It’s also important to note that any video conferencing tool or videos obtained from public video sharing/streaming platforms are susceptible to this attack.
Therefore, to prevent your meeting attendees from snooping on what you’re typing, follow these tips for greater peace-of-mind:
Avoid giving keyboard snoopers the upper hand by making your password or passphrase as unique as the information it’s protecting. If a hacker does manage to guess your password for one of your online accounts, they will likely check for repeat credentials across multiple sites. By using different passwords or passphrases for your online accounts, you can remain calm and collected knowing that the majority of your data is secure if one of your accounts becomes vulnerable.
Two or multi-factor authentication provides an extra layer of security, as it requires multiple forms of verification like texting or emailing a secure code to verify your identity. Most popular online sites like Gmail, Dropbox, LinkedIn, Facebook, etc. offer multi-factor authentication, and it takes just a few minutes to set it up. This reduces the risk of successful impersonation by criminals who may have uncovered your information by keyboard snooping.
Take your security to the next level with a password manager, like the one included in McAfee Total Protection. A password manager can help you create strong passwords, remove the hassle of remembering numerous passwords, and log you on to websites automatically.

Technology has come in handy for most of us during these days of pandemic distancing. But for the -at-risk, homebound senior population, technology has been a lifeline connecting them to family members, online services, and healthcare. Still, this unprecedented shift to virtual life has also come with potential risks that seniors and their families should keep in mind.
According to a Pew study, senior adults continue to become more digitally connected, but adoption rates continue to trail younger users, and digital divides remain. The study also revealed that 77% of older adults needed assistance when it came to learning how to use technology.
If you are a senior or someone helping a senior become more tech-savvy, online safety should be a priority. Here are just some of the risks seniors may encounter and some helpful ways to stay safe.
Secure home routers and devices. Be sure to change your router’s default username and password to something strong and unique. Also, change the default passwords of any connected device before connecting to your home network. IoT (Internet of Things) devices are all the technologies under your roof that can connect such as security systems, healthcare monitors, hearing aids, and smart TVs. These technologies are embedded with sensors or software that can connect and exchange data with other household devices — and each must be secured to close privacy gaps. There are also routers with embedded security, to help secure the home from threats, no matter what devices is connected to the home network.
Use strong passwords. Strong passwords are essential for in-home devices, personal devices, social media sites, and any healthcare or banking portal. Creating a strong password is also a front-line defense against identity theft and fraud. For seniors, keeping passwords in one place is important, but can be hard to remember them all. comprehensive security software includes password management functionality, which makes it easer, to create and safely archive your passwords. -.
Avoid scams. There are a number of scams that target seniors. Phishing scams are emails that look legitimate that end up taking millions from seniors every year. For this reason, never click on suspicious links from government agencies, banks, hospitals, brokerages, charities, or bill collectors unless you are certain they are legitimate. Scammers use these malicious links to con people out of giving away cash or personal data that can be used to create a number of fraudulent accounts. Consider protecting all personal devices with a comprehensive security solution.
Use a personal VPN. A Virtual Private Network (VPN) encrypts (or scrambles) your data when you connect to the Internet and enables you to browse or bank with your credentials and history protected. To learn about VPNs, watch this video.
Beware of dating scams. People aren’t always who they appear to be online. And while dating scams can happen to any age group, they can be especially harmful to a vulnerable senior who may be lonely and living on a limited income. Love scam red flags: Beware of people who claim to be from the U.S. but often travel or work overseas. Also, avoid people who profess their love too quickly, share personal struggles too soon, and never meet face-to-face.
Take a closer look. Fraudulent websites look very real these days. A secure website will have an “https” in the browser’s address bar. The “s” stands for “secure.” If the web address or URL is just http, it’s not a secure site. Still unsure? Read reviews of the site from other users before making a purchase. Never send cash, cashier’s check, or a personal check to any online vendor. If purchasing, always use a credit card in case there is a dispute.
Never share personal data. Be wary of emails or websites that require you to give personal information, such as your social security number, phone number, account, or family information. This includes those fun social media quizzes, which are also ways that cybercriminals can find out your personal details, such as a pets name, year you were born, your home town. All those pieces of personal data can be used to commit identity theft.
Monitor financial accounts. Nowadays, it’s essential to review all financial statements for fraudulent activity. If suspicious activity is found, report it to your bank or credit card account immediately. It’s also a good idea to put a credit alert on your accounts to detect potential fraud.
This unique time has issued unique challenges to every age group. However, if you know a senior, keep their potential technology needs in mind. Check in from time to time and offer your help. If you are a tech-savvy senior (and I know many), consider reaching out to peers who may be struggling and afraid to ask. In addition, YouTube has a number of easy-to-understand videos on any tech question. In addition, both Apple and Microsoft stores offer free advice on their products and may also help. Just be sure to visit their official websites to reach legitimate tech support channels.
