Cisco Live is the premier destination for Cisco customers and partners to gain knowledge and build community. Our teams work hard to deliver education and inspiration, ignite creativity, deliver practical know-how, and accelerate the connections that fuel your digital future.
The Cisco Secure team is excited to share our expertise to help power the strategies – and safety – of your organization.
In 2023, the threat landscape will evolve to one that sees attacks on every surface, from criminals who are opportunistic, yet laser-focused on their goal. The attacks themselves could be email-borne, directly targeted, socially based, or a mix of all three.
Criminals will target vulnerabilities, operational deficiencies, suppliers, and business partners, as a means of accomplishing their goals. They will use the target’s own environment and take advantage of existing people and technology problems, including alert fatigue and staffing shortages.
To face this reality and address the needs of organizations both large and small, Cisco will continue to focus on education and innovation in the areas of preventing insider threats, providing consistent and informed alerts, enabling actionable intelligence, and delivering solutions to implement a zero-trust security framework.
As the organization that pioneered networking, we are driven to secure every connection, providing end-to-end protection for users and devices across multiple clouds and networks with a seamless experience.
As our vision for the integrated Cisco Security Cloud evolves, we’re continuing to challenge existing models and unify security and networking, with foundational elements that execute on this vision. From verified push – which protects organizations from MFA-focused phishing attacks – to Wi-Fi Fingerprint, and Remembered Devices, the performance enhancements with Enterprise Single Sign-on and Cisco+ Secure Connect, we continue to meet our customers where they are, offering true zero trust, with frictionless experiences for the hybrid workforce.
We’re excited to celebrate the following innovations and updates announced at Cisco Live EMEA:
Finding the balance between usability and security is now easier than ever. With Risk-Based Authentication, users have the access they need, secured by real-time contextual signals. Organizations can increase security efficacy by dynamically adjusting authentication requirements based on risk levels and by enabling safer end-user behavior. Risk-based authentication now includes wi-fi fingerprint, remembered device, and verified push features, which work together to reduce risk while preserving user experience by only requesting additional interaction for suspicious logins or a change in risk.
Our Enterprise Ready Single Sign-on expands Duo SSO with three new capabilities to easily connect single sign-on to modern apps and empower end users. By adding major protocol support, improved admin tooling, and SSO on demand password resets, organizations enable easier and more secure access from anywhere.
Cisco SD-WAN customers can now enjoy all the benefits of a turnkey, single-vendor SASE solution that brings together industry-leading networking with security: Cisco+ Secure Connect. This new integration gives Cisco SD-WAN (powered by Viptela) customers fast, secure private application and internet access, enabling them to deliver a secure experience, anywhere work happens.
We are also announcing the introduction of industry-first Business Risk Observability, an enhancement of our Full-Stack Observability application security solution. Available through Cisco Secure Application, which is integrated into Cisco AppDynamics, it provides a business risk scoring solution which brings together Kenna Risk Meter score distribution and Business Transactions from Cisco AppDynamics and integrates with Panoptica for API security and Talos for threat intelligence.
The initial findings from our first Cybersecurity Readiness Index reveal that while technology to devices is widely adopted, more progress is needed to protect identity, networks and applications. The report assessed the preparedness of companies around the world to safeguard against cyber threats in the current environment. See our key findings and security readiness trends, with the full report launching in the coming weeks.
As we navigate 2023, we will continue to face uncertainties and challenges. We are fully committed to our customers and partners in the journey to provide security resilience, supporting a frictionless user experience, and solutions threat intelligence that work to continually minimize risk.

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.

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!

Lots of exciting things happening at Cisco, and for our customers, all to help them better prepare for what’s next. Case in point, we just returned from a very successful Cisco Partner Summit where the spotlight shined on cyber security. When our executives were on stage talking about solutions, the attendees heard a very catchy phrase; “if it’s connected, it’s protected.” A cool phrase, but there is more to that phrase and much more behind it.
To tie both connected and protected together, it’s good to note that Cisco is uniquely positioned as a security vendor with 80% of the worldwide internet traffic running through our network hardware and secured by our open platform, with hundreds of thousands of customers benefitting from automation, and from enriched and prioritized threat intel via our Extended Detection and Response (XDR) capabilities. That means a vast amount of unique insights for our customers to become more resilient, stay ahead of threats, be more confident, and benefit from less risk.
As examples of these questions above:
(1) what about proof points on the above?
(2) and do Cisco’s capabilities align with what customers want and need?
Let’s find out on the first by bringing the XDR aspect of security into the discussion, and the second by observing responses from a Forrester Total Economic Impact
(TEI) study commissioned by Cisco, both points utilizing our Secure Endpoint solution.
First off, in simple terms, XDR provides the benefit of integrating threat intel from all control points of the security platform and combines that into actionable insights for better, faster, and where appropriate, prioritized remediation of the most critical threats, i.e. XDR helps security teams to identify the threats that can do the most damage and enables the workflows to neutralize those threats first.
And here is where the proof point comes in. One of the most critical components of XDR is endpoint security. And in the case of Cisco, it’s our Secure Endpoint solution. Cisco recently participated in the AV-Comparatives’ Endpoint Prevention and Response (EPR) Test. The AV-C test is described by that independent test organization as “… the most comprehensive test of EPR products ever performed.” Secure Endpoint was one of the 10 endpoint security products in the test that were subjected to 50 separate targeted attack scenarios, which used a variety of different techniques.
Here are the highlights of the AV-C EPR report where Cisco Secure Endpoint:
Stunning results and confidence building for our customers that Cisco is effective in endpoint security. Read the complete AV-C EPR Test Report here.
And then, what about the second proof point – is Cisco providing what customers want & need?
Cisco commissioned Forrester Consulting to perform an unbiased cost-benefit analysis of our Cisco Secure Endpoint product. The report yielded the highlights below, based upon a composite organization, and also includes 20+ outstanding customer quotes.
Here’s the Forrester TEI Study bottom line for the composite organization:
Very good results and again, confidence building for our customers that Cisco is effective in endpoint security. Read the Forrester “The Total Economic Impact Of Cisco Secure Endpoint” Study here.
One last thing, what about those customer quotes? Here are a couple of examples:

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.

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.
To learn more, check out the eBook – Passwordless: The Future of Authentication, which outlines a 5-step path to get started. And watch the passwordless product demo in this on-demand webinar .

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.

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!

During our threat hunting exercises in recent months, we’ve started to observe a distinguishing pattern of msiexec.exe usage across different endpoints. As we drilled down to individual assets, we found traces of a recently discovered malware called Raspberry Robin. The RedCanary Research Team first coined the name for this malware in their blog post, and Sekoia published a Flash Report about the activity under the name of QNAP Worm. Both articles offer great analysis of the malware’s behavior. Our findings support and enrich prior research on the topic.
Raspberry Robin is a worm that spreads over an external drive. After initial infection, it downloads its payload through msiexec.exe from QNAP cloud accounts, executes its code through rundll32.exe, and establishes a command and control (C2) channel through TOR connections.
Let’s walkthrough the steps of the kill-chain to see how this malware functions.
Raspberry Robin is delivered through infected external disks. Once attached, cmd.exe tries to execute commands from a file within that disk. This file is either a .lnk file or a file with a specific naming pattern. Files with this pattern exhibit a 2 to 5 character name with an usually obscure extension, including .swy, .chk, .ico, .usb, .xml, and .cfg. Also, the attacker uses an excessive amount of whitespace/non printable characters and changing letter case to avoid string matching detection techniques. Example command lines include:
File sample for delivery can be found in this URL:
https://www.virustotal.com/gui/file/04c13e8b168b6f313745be4034db92bf725d47091a6985de9682b21588b8bcae/relations
Next, we observe explorer.exe running with an obscure command line argument, spawned by a previous instance of cmd.exe. This obscure argument seems to take the name of an infected external drive or .lnk file that was previously executed. Some of the samples had values including USB, USB DISK, or USB Drive, while some other samples had more specific names. On every instance of explorer.exe we see that the adversary is changing the letter case to avoid detection:
After delivery and initial execution, cmd.exe spawns msiexec.exe to download the Raspberry Robin payload. It uses -q or /q together with standard installation parameter to operate quietly. Once again, mixed case letters are used to bypass detection:
As you can see above, URLs used for payload download have a specific pattern. Domains use 2 to 4 character names with obscure TLDs including .xyz, .hk, .info, .pw, .cx, .me, and more. URL paths have a single directory with a random string 11 characters long, followed by hostname and the username of the victim. On network telemetry, we also observed the Windows Installer user agent due to the usage of msiexec.exe. To detect Raspberry Robin through its URL pattern, use this regex:
^http[s]{0,1}\:\/\/[a-zA-Z0-9]{2,4}\.[a-zA-Z0-9]{2,6}\:8080\/[a-zA-Z0-9]+\/.*?(?:-|\=|\?).*?$
If we look up the WHOIS information for given domains, we see domain registration dates going as far back as February 2015. We also see an increase on registered domains starting from September 2021, which aligns with initial observations of Raspberry Robin by our peers.

Associated domains have SSL certificates with the subject alternative name of q74243532.myqnapcloud.com, which points out the underlying QNAP cloud infra. Also, their URL scan results return login pages to QTS service of QNAP:
Once the payload is downloaded, it is executed through various system binaries. First, rundll32.exe uses the ShellExec_RunDLL function from shell32.dll to leverage system binaries such as msiexec.exe, odbcconf.exe, or control.exe. These binaries are used to execute the payload stored in C:\ProgramData\[3 chars]\
It is followed by the execution of fodhelper.exe, which has the auto elevated bit set to true. It is often leveraged by adversaries in order to bypass User Account Control and execute additional commands with escalated privileges [3]. To monitor suspicious executions of fodhelper.exe, we suggest monitoring its instances without any command line arguments.
Raspberry Robin sets up its C2 channel through the additional execution of system binaries without any command line argument, which is quite unusual. That likely points to process injection given elevated privileges in previous steps of execution. It uses dllhost.exe, rundll32.exe, and regsvr32.exe to set up a TOR connection.
In Cisco Global Threat Alerts available through Cisco Secure Network Analytics and Cisco Secure Endpoint, we track this activity under the Raspberry Robin threat object. Image 3 shows a detection sample of Raspberry Robin:
Raspberry Robin tries to remain undetected through its use of system binaries, mixed letter case, TOR-based C2, and abuse of compromised QNAP accounts. Although we have similar intelligence gaps (how it infects external disks, what are its actions on objective) like our peers, we are continuously observing its activities.

Eighty-one percent of organizations told Gartner they have a multi-cloud strategy. As more organizations subscribe to cloud offerings for everything from hosted data centers to enterprise applications, the topology of the typical IT environment grows increasingly complex.
Now add the proliferation of hybrid work environments, the rapid ascendance of Internet of Things (IoT) devices, and an increasingly sophisticated and malicious cyber threat landscape, and it becomes immediately clear that protecting the integrity of your IT ecosystem is now a next-level problem.
In an unpredictable world, organizations everywhere are investing in initiatives that will infuse resilience into every aspect of their business, from finance to supply chains. To protect those investments, we believe they also need to invest in security resilience — the ability to protect your business against threats and disruption, and to respond to changes confidently so you can emerge even stronger.
This requires a next-level solution.
That’s why we’re building the Cisco Security Cloud — a global, cloud-delivered, integrated platform that secures and connects organizations of any shape and size. This cloud-native service is aimed at helping you protect users, devices and applications across your entire ecosystem. It will be a comprehensive, integrated set of services designed to scale with your business.
The Cisco Security Cloud will directly address these challenges by bringing together the depth and breadth of the Cisco security portfolio, and is:
We have been on this journey for years. We at Cisco Secure have been delivering key components of this security cloud, and those solutions already protect 840,000 networks, 67 million mailboxes and 87 million endpoints for customers the world over.
And today at the RSA Conference, we’re taking the next step by announcing our latest innovations addressing four key areas:
Today we are announcing Cisco’s turnkey Secure Access Service Edge (SASE) offering, Cisco+ Secure Connect Now, to simplify how organizations connect and protect users, devices, data, and applications, anywhere. Built on the Meraki platform, and available as a subscription, it unifies security and networking operations, as well as client connectivity and visibility into a single cloud-native solution, that can be set up in minutes.
Cisco is continuing to build out continuous trusted access solutions that that constantly verify user and device identity, device posture, vulnerabilities, and indicators of compromise. To evaluate risk after authentication, location information is critical, but we think GPS data is too intrusive. So today we are introducing a new patent-pending Wi-Fi Fingerprint capability (available in Public Preview this summer) to understand user location without compromising location privacy. We are also announcing new Session Trust Analysis capabilities to evaluate risk after login by using open standards for shared signals and events. We will unveil the first integration of this technology with a demo of Duo MFA and Box this week.
As organizations become more interconnected as ecosystems, and attacks become more sophisticated and personalized, it is no longer adequate to evaluate risk and threats generically across the industry. Organizations need deeper levels of advice and expertise. We are excited to launch the new Talos Intelligence On-Demand service, available now, offering custom research on the threat landscape unique to each organization. Talos Intelligence on Demand can assist with custom research, and brief our customers on the unique risks, threats, and mitigation strategies for their organizations.
Simplification is critical to driving better security efficacy. To that end, we are excited to announce the new Cisco Secure Client (available this summer), combining AnyConnect, Secure Endpoint, and Umbrella, to simplify how administrators and users manage endpoints. This follows the launch of the new cloud-delivered Secure Firewall Management Center, which unifies management for both cloud and on-premise firewalls.
There is more work to be done, of course, and today’s announcements at the RSA Conference are the latest advances in support of this vision. We will continue working on all aspects of the Security Cloud to improve our customers’ security resilience in the face of unprecedented change and increasing threats. Because next-level problems deserve next-level solutions.

The SASE landscape is full of vendors. So full, in fact, that the entire SASE vendor market grew 37% in just a year between 2020 and 2021. It’s clear that SASE is on the top of everyone’s minds. Why? SASE is the evolution of networking and security – an architecture that converges them into a single, cloud delivered service. This streamlined approach is key to securing and connecting the always-on, work-from-anywhere modern work model.
Traditional, siloed security solutions aren’t equipped to handle all the challenges that come along with a multi-environment IT reality. The accelerated transition to hybrid work has increased complexity in managing security and connectivity. Businesses face increased cloud adoption, bring-your-own-device connectivity, increasingly complex cybersecurity threats, and the constant change. Businesses have struggled to keep up with the gaps in coverage, and tech vendors have hurried in to fill the space with cloud security and networking options. But not all SASE solutions are created equal.
In the rush to compete in the market for the future of networking and security, vendors positioned themselves as SASE without offering a truly integrated approach that’s critical to SASE success. Many vendors offer cloud security solutions with no native or integrated SD-WAN networking capability. Others aren’t backed with robust threat intelligence that enable them to effectively deliver on threat detection and prevention. Some don’t offer the flexibility and scalability that businesses need to adopt cloud-delivered security. Many don’t offer open, integrated management platforms. Plus, most organizations face monumental complexity – the exact opposite of what SASE should deliver – due to using several different vendors for different security functions.
Dell’Oro Group, the trusted source for market information in the telecommunications, enterprise networks, and data center IT infrastructure industries, recognized Cisco as the SASE Market Share Leader in 2021, with 19% of the total market share by revenue.
“Cisco was the SASE market share leader because of the combined strength of their networking (SD-WAN) and security capabilities (including secure web gateway, cloud access security broker, and zero trust network access),” said Mauricio Sanchez, Research Director, Network Security, and SASE & SD-WAN at Dell’Oro Group.
At Cisco, we began our journey by pioneering network connectivity and offering innovative tech solutions; today, we have the most SD-WAN market share and secure 100% of Fortune 100 companies. From that foundation, we’ve been able to build and deliver award-winning cloud security solutions that, when combined with our networking services, create a robust, complete SASE architecture.
Cisco’s SASE approach combines networking, client connectivity, security, and internet and cloud intelligence capabilities and helps organizations:
The benefits of a SASE model are unlocked by working with a single vendor who can bring together best-in-class networking, security, and internet and cloud intelligence—while offering the flexibility and investment protection to transition to the cloud at your pace.
While Cisco provides a comprehensive SASE framework, we know that everyone’s journey to the cloud is different. Organizations, especially now, are shifting and refining their strategies, particularly when it comes to cybersecurity and the increase of both the number and type of threats that businesses see every day. Cisco can help organizations make the most of their existing security and networking investments, while also offering increased and amplified functionality across their security infrastructure. Wherever you are on your journey to SASE, Cisco Secure has the unparalleled experience and reputation that can support you on your next steps.
Check out our SASE demo to find out how Cisco delivers a simple, secure, and scalable approach to SASE.

Sometimes in order to move forward effectively, it’s good to take stock of where we’ve been. In this blog, we’ll review a concept that has been foundational to networking and cybersecurity from the beginning: the session. Why focus on the session? As the philosophy of Zero Trust is adopted more broadly in the security industry, it’s important to understand the building blocks of access. The session is a fundamental component of access to any resource.
To get things started, let’s start with a definition. A simple definition of a session might be: “a period of time devoted to a particular activity.” Not so bad, but the complexity for internet and network security springs from scoping the “particular activity.”
The internet exists on top of a standardized suite of protocols that govern how data can be transmitted or exchanged between different entities. This suite, now generally referred to as the TCP/IP stack, is comprised of four distinct layers that delineate how data flows between networked resources. This is where the scoping of a session becomes obscure. The “particular activity” could refer to the network layer, which is responsible for establishing communications between the actual physical networks. Or, perhaps the activity refers to the Internet layer, which ensures the packets of data reach their destinations across network boundaries. The activity could also be the transport layer, responsible for the reliability of end-to-end communication across the network. It could also be referencing the application layer, the highest layer of the TCP/IP stack, which is responsible for the interface and protocols used by applications and users. For the familiar, these layers were originally defined in the OSI model.
This layering framework works well for establishing the distinct session types and how we can begin to protect them. However, the rise of cloud-based services means we must now also look at how sessions are defined in relation to the cloud — especially as we look to provide security and access controls. At the application layer, we now have client devices with web browsers and applications that communicate to a cloud service. Additionally, cloud services can be one or a combination of SaaS, PaaS and IaaS, each defining their own session and thus access.
With all the different classes of sessions, there are different mechanisms and protocols by which authentication and authorization are employed to eventually provide that access. All sessions use some type of account or credential to authenticate and evaluate a set of variables to determine authorization or access. Some of these variables may also be similar across different sessions. For example, an enterprise may evaluate the device’s security posture (e.g. it is running the latest OS patches) as a variable to grant access at both the network and application layer. Similarly, the same username and password may be used across different session layers.
However, each layer might also use distinct and specific variables to evaluate the appropriate access level. For instance, the network interface layer may want to ensure cryptographic compliance of the network interfaces. A cloud service may evaluate geographical or regional compliance. The common practice today is to have every session layer act alone to make its own access decision.
Let’s take a step back and review.
Now, let’s explore something new: what if the variables and access evaluation outcomes were shared seamlessly across session layers?
What if recent network context and activity were used to inform cloud access decisions? Or, recent user access decisions across the network layers be used to inform cloud application controls? Think about the enhanced resilience provided if network-based risk signal like packet information could be appropriately mapped and shared with the cloud application layer. Sharing information across session boundaries provides more robust fulfillment of Zero Trust principles by striving to evaluate security context as holistically as possible at the time of access.
In order to build a future where security decisions are informed by broader and continuous context, we’ll need tools and protocols that help us bridge tools and map data across them. To provide improved access and security, both the bridge and the correct mapping must be in place. It’s one thing to get the data transferred to another tool, it’s quite another to map that data into relevance for the new tool. For example, how do we map a privileged application credential to a device? And, then how do we map relevant context across systems?
The good news is that work is starting to enable a future where regardless of session definition, security context can be mapped and shared. Protocols such as the Shared Signals and Events and the Open Policy Agent are evolving to enable timely and dynamic signal sharing between tools, but they are nascent and broader adoption is required. Cisco has already contributed a technical reference architecture as a guide for Shared Signals and Events. We hope that by accelerating the adoption of these standards the industry gets one step closer to actively sharing relevant security context across OSI layers. While the road ahead won’t be easy, we think the sharing signals will make for a more resilient and robust security future.
