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.

Let’s face it: Having “2022 election” in the headline above is probably the only reason anyone might read this story today. Still, while most of us here in the United States are anxiously awaiting the results of how well we’ve patched our Democracy, it seems fitting that Microsoft Corp. today released gobs of security patches for its ubiquitous Windows operating systems. November’s patch batch includes fixes for a whopping six zero-day security vulnerabilities that miscreants and malware are already exploiting in the wild.
Probably the scariest of the zero-day flaws is CVE-2022-41128, a “critical” weakness in the Windows scripting languages that could be used to foist malicious software on vulnerable users who do nothing more than browse to a hacked or malicious site that exploits the weakness. Microsoft credits Google with reporting the vulnerability, which earned a CVSS score of 8.8.
CVE-2022-41073 is a zero-day flaw in the Windows Print Spooler, a Windows component that Microsoft has patched mightily over the past year. Kevin Breen, director of cyber threat research at Immersive Labs, noted that the print spooler has been a popular target for vulnerabilities in the last 12 months, with this marking the 9th patch.
The third zero-day Microsoft patched this month is CVE-2022-41125, which is an “elevation of privilege” vulnerability in the Windows Cryptography API: Next Generation (CNG) Key Isolation Service, a service for isolating private keys. Satnam Narang, senior staff research engineer at Tenable, said exploitation of this vulnerability could grant an attacker SYSTEM privileges.
The fourth zero-day, CVE-2022-41091, was previously disclosed and widely reported on in October. It is a Security Feature Bypass of “Windows Mark of the Web” – a mechanism meant to flag files that have come from an untrusted source.
The other two zero-day bugs Microsoft patched this month were for vulnerabilities being exploited in Exchange Server. News that these two Exchange flaws were being exploited in the wild surfaced in late September 2022, and many were surprised when Microsoft let October’s Patch Tuesday sail by without issuing official patches for them (the company instead issued mitigation instructions that it was forced to revise multiple times). Today’s patch batch addresses both issues.
Greg Wiseman, product manager at Rapid7, said the Exchange flaw CVE-2022-41040 is a “critical” elevation of privilege vulnerability, and CVE-2022-41082 is considered Important, allowing Remote Code Execution (RCE) when PowerShell is accessible to the attacker.
“Both vulnerabilities have been exploited in the wild,” Wiseman said. “Four other CVEs affecting Exchange Server have also been addressed this month. Three are rated as Important, and CVE-2022-41080 is another privilege escalation vulnerability considered Critical. Customers are advised to update their Exchange Server systems immediately, regardless of whether any previously recommended mitigation steps have been applied. The mitigation rules are no longer recommended once systems have been patched.”
Adobe usually issues security updates for its products on Patch Tuesday, but it did not this month. For a closer look at the patches released by Microsoft today and indexed by severity and other metrics, check out the always-useful Patch Tuesday roundup from the SANS Internet Storm Center. And it’s not a bad idea to hold off updating for a few days until Microsoft works out any kinks in the updates: AskWoody.com usually has the lowdown on any patches that may be causing problems for Windows users.
As always, please consider backing up your system or at least your important documents and data before applying system updates. And if you run into any problems with these updates, please drop a note about it here in the comments.
Responding to a recent surge in AI-generated bot accounts, LinkedIn is rolling out new features that it hopes will help users make more informed decisions about with whom they choose to connect. Many LinkedIn profiles now display a creation date, and the company is expanding its domain validation offering, which allows users to publicly confirm that they can reply to emails at the domain of their stated current employer.
LinkedIn’s new “About This Profile” section — which is visible by clicking the “More” button at the top of a profile — includes the year the account was created, the last time the profile information was updated, and an indication of how and whether an account has been verified.
LinkedIn also said it is adding a warning to some LinkedIn messages that include high-risk content, or that try to entice the user into taking the conversation to another platform (like WeChat).
“We may warn you about messages that ask you to take the conversation to another platform because that can be a sign of a scam,” the company said in a blog post. “These warnings will also give you the choice to report the content without letting the sender know.”
In late September 2022, KrebsOnSecurity warned about the proliferation of fake LinkedIn profiles for Chief Information Security Officer (CISO) roles at some of the world’s largest corporations. A follow-up story on Oct. 5 showed how the phony profile problem has affected virtually all executive roles at corporations, and how these fake profiles are creating an identity crisis for the businesses networking site and the companies that rely on it to hire and screen prospective employees.
Reporting here last month also tracked a massive drop in profiles claiming to work at several major technology companies, as LinkedIn apparently took action against hundreds of thousands of inauthentic accounts that falsely claimed roles at these companies.
For example, on October 10, 2022, there were 576,562 LinkedIn accounts that listed their current employer as Apple Inc. The next day, half of those profiles no longer existed. At around the same time, the number of LinkedIn profiles claiming current roles at Amazon fell from roughly 1.25 million to 838,601 in just one day, a 33 percent drop.
For whatever reason, the majority of the phony LinkedIn profiles reviewed by this author were young women with profile photos that appear to have been generated by artificial intelligence (AI) tools.
“We’re seeing rapid advances in AI-based synthetic image generation technology and we’ve created a deep learning model to better catch profiles made with this technology,” LinkedIn’s Oscar Rodriguez wrote. “AI-based image generators can create an unlimited number of unique, high-quality profile photos that do not correspond to real people.”
It remains unclear who or what is behind the recent proliferation of fake executive profiles on LinkedIn, but likely they are from a combination of scams. Cybersecurity firm Mandiant (recently acquired by Google) told Bloomberg that hackers working for the North Korean government have been copying resumes and profiles from leading job listing platforms LinkedIn and Indeed, as part of an elaborate scheme to land jobs at cryptocurrency firms.
Identity thieves have been known to masquerade on LinkedIn as job recruiters, collecting personal and financial information from people who fall for employment scams.
Also, fake profiles also may be tied to so-called “pig butchering” scams, wherein people are lured by flirtatious strangers online into investing in cryptocurrency trading platforms that eventually seize any funds when victims try to cash out.
Welcome back! 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.

A 25-year-old Finnish man has been charged with extorting a once popular and now-bankrupt online psychotherapy company and its patients. Finnish authorities rarely name suspects in an investigation, but they were willing to make an exception for Julius “Zeekill” Kivimaki, a notorious hacker who — at the tender age of 17 — had been convicted of more than 50,000 cybercrimes, including data breaches, payment fraud, operating botnets, and calling in bomb threats.
In late October 2022, Kivimaki was charged (and arrested in absentia, according to the Finns) with attempting to extort money from the Vastaamo Psychotherapy Center. On October 21, 2020, Vastaamo became the target of blackmail when a tormentor identified as “ransom_man” demanded payment of 40 bitcoins (~450,000 euros at the time) in return for a promise not to publish highly sensitive therapy session notes Vastaamo had exposed online.
In a series of posts over the ensuing days on a Finnish-language dark net discussion board, ransom_man said Vastaamo appeared unwilling to negotiate a payment, and that he would start publishing 100 patient profiles every 24 hours “to provide further incentive for the company to continue communicating with us.”
“We’re not asking for much, approximately 450,000 euros which is less than 10 euros per patient and only a small fraction of the around 20 million yearly revenues of this company,” ransom_man wrote.
When Vastaamo declined to pay, ransom_man shifted to extorting individual patients. According to Finnish police, some 22,000 victims reported extortion attempts targeting them personally, targeted emails that threatened to publish their therapy notes online unless paid a 500 euro ransom.
The extortion message targeted Vastaamo patients.
On Oct. 23, 2020, ransom_man uploaded to the dark web a large compressed file that included all of the stolen Vastaamo patient records. But investigators found the file also contained an entire copy of ransom_man’s home folder, a likely mistake that exposed a number of clues that they say point to Kivimaki.
Ransom_man quickly deleted the large file (accompanied by a “whoops” notation), but not before it had been downloaded a number of times. The entire archive has since been made into a searchable website on the Dark Web.
Among those who grabbed a copy of the database was Antti Kurittu, a team lead at Nixu Corporation and a former criminal investigator. In 2013, Kurittu worked on investigation involving Kivimaki’s use of the Zbot botnet, among other activities Kivimaki engaged in as a member of the hacker group Hack the Planet.
“It was a huge opsec [operational security] fail, because they had a lot of stuff in there — including the user’s private SSH folder, and a lot of known hosts that we could take a very good look at,” Kurittu told KrebsOnSecurity, declining to discuss specifics of the evidence investigators seized. “There were also other projects and databases.”
Kurittu said he and others he and others who were familiar with illegal activities attributed to Kivimäki couldn’t shake suspicion that the infamous cybercriminal was also behind the Vastaamo extortion.
“I couldn’t find anything that would link that data directly to one individual, but there were enough indicators in there that put the name in my head and I couldn’t shake it,” Kurittu said. “When they named him as the prime suspect I was not surprised.”
A handful of individually extorted victims paid a ransom, but when news broke that the entire Vastaamo database had been leaked online, the extortion threats no longer held their sting. However, someone would soon set up a site on the dark web where anyone could search this sensitive data.
Kivimaki stopped using his middle name Julius in favor of his given first name Aleksanteri when he moved abroad several years ago. A Twitter account by that name was verified by Kivimaki’s attorney as his, and through that account he denied being involved in the Vastaamo extortion.
“I believe [the Finnish authorities] brought this to the public in order to influence the decision-making of my old case from my teenage years, which was just processed in the Court of Appeal, both cases are investigated by the same persons,” Kivimaki tweeted on Oct. 28.
Kivimaki is appealing a 2020 district court decision sentencing him to “one year of conditional imprisonment for two counts of fraud committed as a young person, and one of gross fraud, interference with telecommunications as a young person, aggravated data breach as a young person and incitement to fraud as a young person,” according to the Finnish tabloid Ilta-Sanomat.
“Now in the Court of Appeal, the prosecutor is demanding a harsher punishment for the man, i.e. unconditional imprisonment,” reads the Ilta-Sanomat story. “The prosecutor notes in his complaint that the young man has been committing cybercrimes from Espoo since he was 15 years old, and the actions have had to be painstakingly investigated through international legal aid.”
As described in this Wired story last year, Vastaamo filled an urgent demand for psychological counseling, and it won accolades from Finnish health authorities and others for its services.
“Vastaamo was a private company, but it seemed to operate in the same spirit of tech-enabled ease and accessibility: You booked a therapist with a few clicks, wait times were tolerable, and Finland’s Social Insurance Institution reimbursed a big chunk of the session fee (provided you had a diagnosed mental disorder),” William Ralston wrote for Wired. “The company was run by Ville Tapio, a 39-year-old coder and entrepreneur with sharp eyebrows, slicked-back brown hair, and a heavy jawline. He’d cofounded the company with his parents. They pitched Vastaamo as a humble family-run enterprise committed to improving the mental health of all Finns.”
But for all the good it brought, the healthcare records management system that Vastaamo used relied on little more than a MySQL database that was left dangerously exposed to the web for 16 months, guarded by nothing more than an administrator account with a blank password.
The Finnish daily Iltalehti said Tapio was relieved of his duties as CEO of Vastaamo in October 2020, and that in September, prosecutors brought charges against Tapio for a data protection offense in connection with Vastaamo’s information leak.
“According to Vastaamo, the data breach in Vastaamo’s customer databases took place in November 2018,” Iltalehti reported last month. “According to Vastaamo, Tapio concealed information about the data breach for more than a year and a half.”

Going beyond the hype, passwordless authentication is now a reality. Cisco Duo’s passwordless authentication is now generally available across all Duo Editions.
“Cisco Duo simplifies the passwordless journey for organizations that want to implement phishing-resistant authentication and adopt a zero trust security strategy.”
—Jack Poller, Senior Analyst, ESG
We received tremendous participation and feedback during our public preview, and we are now excited to bring this capability to our customers and prospects.
“Over the last few years, we have increased our password complexities and required 2FA wherever possible. With this approach, employees had more password lock outs, password fatigue, and forgetting their longer passwords due to password rotations. With Duo Passwordless, we are excited to introduce this feature to our employees to keep our password complexities in place and leverage different Biometric options whether that is using their mobile device, Windows Hello, or a provided FIDO security key.
The Duo Push for passwordless authentication feature is simple and easy and introduces a more pleasant experience overall. Using Duo’s device insight and application policies, we are able to leverage and verify the security of the mobile devices before the device is allowed to be used. To top it off, Duo is connected to our SIEM and our InfoSec team is able to review detailed logs and setup alerts to be able to keep everything secure.”
—Vice President of IT, Banking and Financial Services Customer
As with any new technology, getting to a completely passwordless state will be a journey for many organizations. We see customers typically starting their passwordless journey with web-based applications that support modern authentication. To that effect, Duo’s passwordless authentication is enabled through Duo Single Sign-On (SSO) for federated applications. Customers can choose to integrate their existing SAML Identity provider such as Microsoft (ADFS, Azure), Okta or Ping Identity; or choose to use Duo SSO (Available across all Duo editions).
“Password management is a challenging proposition for many enterprises, especially in light of BYOD and ever increasing sophistication of phishing schemes. Cisco aims to simplify the process with its Duo passwordless authentication that offers out-of-box integrations with popular single sign-on solutions.”
—Will Townsend, Vice President & Principal Analyst, Networking & Security, Moor Insights & Strategy
Duo offers a flexible choice of passwordless authentication options to meet the needs of businesses and their use cases. This includes:
No matter which authentication option you choose, it is secure and inherently multi-factor authentication. We are eliminating the need for the weak knowledge factor (something you know – passwords) which are shared during authentication and can be easily compromised. Instead, we are relying on stronger factors, which are the inherence factor (something you are – biometrics) and possession factor (something you have – a registered device). A user completes this authentication in a single gesture without having to remember a complex string of characters. This significantly improves the user experience and mitigates the risk of stolen credentials and man-in-the-middle (MiTM) attacks.
FIDO2 authentication is regarded as phishing-resistant authentication because it:
Using Duo with FIDO2 authenticators enables organizations to enforce phishing-resistant MFA in their environment. It also complies with the Office of Management and Budget (OMB) guidance issued earlier this year in a memo titled “Moving the U.S. Government Towards Zero Trust Cybersecurity Principles”. The memo specifically requires agencies to use phishing-resistant authentication method.
We understand that getting the IT infrastructure ready to support FIDO2 can be expensive and is typically a long-term project for organizations. In addition, deploying and managing 3rd party security keys creates IT overhead that some organizations are not able to undertake immediately.
Alternatively, using Duo Push for passwordless authentication is an easy, cost effective to get started on a passwordless journey for many organizations, without compromising on security.
We have incorporated security into the login workflow to bind the browser session and the device being used. So, organizations get the same benefits of eliminating use of stolen credentials and mitigation of phishing attacks. To learn more about passwordless authentication with Duo Push, check out our post: Available Now! Passwordless Authentication Is Just a Tap Away.
In addition to going passwordless, many organizations are looking to implement zero trust access in their IT environment. This environment typically is a mix of modern and legacy applications, meaning passwordless cannot be universally adopted. At least not until all applications can support modern authentication.
Additionally, organizations need to support a broad range of use cases to allow access from both managed and unmanaged (personal or 3rd party contractor) devices. And IT security teams need visibility into these devices and the ability to enforce compliance to meet the organization’s security policies such as ensuring that the operating system (OS) and web browser versions are up to date. The importance of verifying device posture at the time of authentication is emphasized in the guidance provided by OMB’s zero trust memorandum – “authorization systems should work to incorporate at least one device-level signal alongside identity information about the authenticated user.”
Duo can help organizations adopt a zero trust security model by enforcing strong user authentication across the board either through passwordless authentication where applicable or thought password + MFA where necessary, while providing a consistent user experience. Further, with capabilities such as device trust and granular adaptive policies, and with our vision for Continuous Trusted Access, organizations get a trusted security partner they can rely on for implementing zero trust access in their environment.

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.

The concept of zero trust is not a new one, and some may even argue that the term is overused. In reality, however, its criticality is growing with each passing day. Why? Because many of today’s attacks begin with the user. According to Verizon’s Data Breach Investigations Report, 82% of breaches involve the human element — whether it’s stolen credentials, phishing, misuse or error.
Additionally, today’s businesses are hyper-connected, meaning that — in addition to your employees — customers, partners and suppliers are all part of your ecosystem. Couple that with hybrid work, IoT, the move to the cloud, and more emboldened attackers, and organizational risk increases exponentially.
Adopting a zero trust model can dramatically reduce this risk by eliminating implicit trust. It has become so crucial, in fact, that several governments including the U.S., UK and Australia have released mandates and guidance for how organizations should deploy zero trust to improve national security.
However, because zero trust is more of a concept than a technology, and so many vendors use the term, organizations struggle with the best way to implement it. At Cisco, we believe you should take a holistic approach to zero trust, starting with what you have and adding on as you identify gaps in your defenses. And while layers of protection are necessary for powerful security, so is ease of use.
Zero trust plays a major role in building security resilience, or the ability to withstand unpredictable threats or changes and emerge stronger. Through zero trust, the identity and security posture of users, devices and applications are continuously checked and verified to prevent network intrusions — and to also limit impact if an unauthorized entity does gain access.
Organizations with high zero trust maturity are twice as likely to achieve business resilience.

Eliminating trust, however, doesn’t really conjure up images of user-friendly technology. No matter how necessary they are for the business, employees are unlikely to embrace security measures that make their jobs more cumbersome and time-consuming. Instead, they want fast, consistent access to any application no matter where they are or which device they are using.
That’s why Cisco is taking a different approach to zero trust — one that removes friction for the user. For example, with Cisco Secure Access by Duo, organizations can provide those connecting to their network with several quick, easy authentication options. This way, they can put in place multi-factor authentication (MFA) that frustrates attackers, not users.
Cisco Secure Access by Duo is a key pillar of zero trust security, providing industry-leading features for secure access, authentication and device monitoring. Duo is customizable, straightforward to use, and simple to set up. It enables the use of modern authentication methods including biometrics, passwordless and single sign-on (SSO) to help organizations advance zero trust without sacrificing user experience. Duo also provides the flexibility organizations need to enable secure remote access with or without a VPN connection.
During Cisco’s own roll-out of Duo to over 100,000 people, less than 1% of users contacted the help desk for assistance. On an annual basis, Duo is saving Cisco $3.4 million in employee productivity and $500,000 in IT help desk support costs. Furthermore, 86,000 potential compromises are averted by Duo each month.
La-Z-Boy, one of the world’s leading residential furniture producers, also wanted to defend its employees against cybersecurity breaches through MFA and zero trust. It needed a data security solution that worked agnostically, could grow with the company, and that was easy to roll out and implement.
“When COVID first hit and people were sent home to work remotely, we started seeing more hacking activity…” said Craig Vincent, director of IT infrastructure and operations at La-Z-Boy. “We were looking for opportunities to secure our environment with a second factor…. We knew that even post-pandemic we would need a hybrid solution.”
“It was very quick and easy to see where Duo fit into our environment quite well, and worked with any application or legacy app, while deploying quickly.” – Craig Vincent, Director of IT Infrastructure and Operations, La-Z-Boy
Today, Duo helps La-Z-Boy maintain a zero trust framework, stay compliant, and get clear visibility into what is connecting to its network and VPN. Zero trust helps La-Z-Boy secure its organization against threats such as phishing, stolen credentials and out-of-date devices that may be vulnerable to known exploits and malware.
As mentioned, zero trust is a framework, not a single product or technology. For zero trust to be truly effective, it must do four things:
Many technology companies may offer a single component of zero trust, or one aspect of protection, but Cisco’s robust networking and security expertise enables us to provide a holistic zero trust solution. Not only can we support all the steps above, but we can do so across your whole IT ecosystem.
Modern organizations are operating multi-environment ecosystems that include a mix of on-premises and cloud technologies from various vendors. Zero trust solutions should be able to protect across all this infrastructure, no matter which providers are in use. Protections should also extend from the network and cloud to users, devices, applications and data. With Cisco’s extensive security portfolio, operating on multiple clouds and platforms, zero trust controls can be embedded at every layer.
Depending on where you are in your security journey, embedding zero trust at every layer of your infrastructure may sound like a lofty endeavor. That’s why we meet customers where they are on their path to zero trust. Whether your first priority is to meet regulatory requirements, secure hybrid work, protect the cloud, or something else, we have the expertise to help you get started. We provide clear guidance and technologies for zero trust security mapped to established frameworks from organizations like CISA and NIST.
Much of our Cisco Secure portfolio can be used to build a successful zero trust framework, but some examples of what we offer include:
All of our technologies and services are backed by the unparalleled intelligence of Cisco Talos — so you always have up-to-date protection as you build your zero trust architecture. Additionally, our open, integrated security platform — Cisco SecureX — makes it simple to expand and scale your security controls, knowing they will work with your other technologies for more unified defenses.
As Italy’s leading insurance company, Sara Assicurazioni requires complete visibility into its extended network, including a multi-cloud architecture and hybrid workforce. The company has adopted a comprehensive zero trust strategy through Cisco Secure.
“Our decentralized users, endpoints, and cloud-based servers and workloads contribute to a large attack surface,” says Paolo Perrucci, director of information and communications technology architectures and operations at Sara Assicurazioni. “With Cisco, we have the right level of visibility on this surface.”
“The main reason we chose Cisco is that only Cisco can offer a global security solution rather than covering one specific point…. Thanks to Cisco Secure, I’m quite confident that our security posture is now many times better because we are leveraging more scalable, state-of-the-art security solutions.” – Luigi Vassallo, COO & CTO, Sara Assicurazioni
