A nonprofit organization is suing the state of Massachusetts on behalf of thousands of low-income families who were collectively robbed of more than a $1 million in food assistance benefits by card skimming devices secretly installed at cash machines and grocery store checkout lanes across the state. Federal law bars states from replacing these benefits using federal funds, and a recent rash of skimming incidents nationwide has disproportionately affected those receiving food assistance via state-issued prepaid debit cards.
The Massachusetts SNAP benefits card looks more like a library card than a payment card.
On Nov. 4, The Massachusetts Law Reform Institute (MLRI) filed a class action lawsuit on behalf of low-income families whose Supplemental Nutrition and Assistance Program (SNAP) benefits were stolen from their accounts. The SNAP program serves over a million people in Massachusetts, and 41 million people nationally.
“Over the past few months, thieves have stolen over a million SNAP dollars from thousands of Massachusetts families – putting their nutrition and economic stability at risk,” the MLRI said in a statement on the lawsuit. “The criminals attach a skimming device on a POS (point of sale) terminal to capture the household’s account information and PIN. The criminals then use that information to make a fake card and steal the SNAP benefits.”
In announcing the lawsuit, the MRLI linked to a story KrebsOnSecurity published last month that examined how skimming thieves increasingly are targeting SNAP payment card holders nationwide. The story looked at how the vast majority of SNAP benefit cards issued by the states do not include the latest chip technology that makes it more difficult and expensive for thieves to clone them.
The story also highlighted how SNAP cardholders usually have little recourse to recover any stolen funds — even in unlikely cases where the victim has gathered mountains of proof to show state and federal officials that the fraudulent withdrawals were not theirs.
Deborah Harris is a staff attorney at the MLRI. Harris said the goal of the lawsuit is to force Massachusetts to reimburse SNAP skimming victims using state funds, and to convince The U.S. Department of Agriculture (USDA) — which funds the program that states draw from — to change its policies and allow states to replace stolen benefits with federal funds.
“Ultimately we think it’s the USDA that needs to step up and tell states they have a duty to restore the stolen benefits, and that USDA will cover the cost at least until there is better security in place, such as chip cards,” Harris told KrebsOnSecurity.
“The losses we’re talking about are relatively small in the scheme of total SNAP expenditures which are billions,” she said. “But if you are a family that can’t pay for food because you suddenly don’t have money in your account, it’s devastating for the family.”
The USDA has not said it will help states restore the stolen funds. But on Oct. 31, 2022, the agency released guidance (PDF) whose primary instructions were included in an appendix titled, Card Security Options Available to Households. Notably, the USDA did not mention the idea of shifting to chip-based SNAP benefits cards.
The recently issued USDA guidance.
“The guidance generally continues to make households responsible for preventing the theft of their benefits as well as for suffering the loss when benefits are stolen through no fault of the household,” Harris said. “Many of the recommendations are not practical for households who don’t have a smartphone to receive text messages and aren’t able to change their PIN after each transaction and keep track of the new PIN.”
Harris said three of the four recommendations are not currently available in Massachusetts, and they are very likely not currently available in other states. For example, she said, Massachusetts households do not have the option of freezing or locking their cards between transactions. Nor do they receive alerts about transactions. And they most certainly don’t have any way to block out-of-state transactions.
“Perhaps these are options that [card] processors and states could provide, but they are not available now as far as we know,” Harris said. “Most likely they would take time to implement.”
The Center for Law and Social Policy (CLASP) recently published Five Ways State Agencies Can Support EBT Users at Risk of Skimming. CLASP says while it is true states can’t use federal funds to replace benefits unless the loss was due to a “system error,” states could use their own funds.
“Doing so will ensure families don’t have to go without food, gas money, or their rent for the month,” CLASP wrote.
That would help address the symptoms of card skimming, but not a root cause. Hardly anyone is suggesting the obvious, which is to equip SNAP benefit cards with the same security technology afforded to practically everyone else participating in the U.S. banking system.
There are several reasons most state-issued SNAP benefit cards do not include chips. For starters, nobody says they have to. Also, it’s a fair bit more expensive to produce chip cards versus plain old magnetic stripe cards, and many state assistance programs are chronically under-funded. Finally, there is no vocal (or at least well-heeled) constituency advocating for change.

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!

Smishing and vishing are scams where criminals attempt to get users to click a fraudulent link through a phone text message, email, or voicemail. These scams are becoming increasingly popular as cybercriminals try to take advantage of people who are more likely to fall for them, such as those who aren’t as familiar with technology or who may be experiencing a crisis.
Be aware that cybercrime and hacking can happen to anyone. Criminals are always looking for new ways to exploit people, and they know that others may not be cautious or recognize the warning signs of phishing scams when using the internet. That’s why it’s important to be aware of the different types of cybercrime and how to protect yourself.
This article discusses how to protect yourself from smishing attempts and scams where criminals try to get you to click on a fraudulent link or respond to their voicemail message to steal your personal data.
Most people are familiar with phishing scams, where scammers try to trick you into giving them your personal or financial information by pretending to be a legitimate company or organization. But have you ever heard of smishing or vishing?
Smishing is a type of phishing scam where attackers send SMS messages (or text messages) to trick victims into sharing personal information or installing malware on their devices. Vishing is almost identical to smishing, except cybercriminals use VoIP (Voice over IP) to place phone calls to trick victims instead of SMS (short message service) messages.
Smishing messages often appear to be from a legitimate source, such as a well-known company or government agency. It may even include urgent language or threats in an effort to get victims to act quickly. In some cases, the message may also include a link that directs victims to a fake website where they are prompted to enter personal information or download malware.
Here are some examples of smishing text messages hackers use to steal your personal details:
If you fall for a smishing scam, you could end up giving away your personal information or money. Cybercriminals use smishing messages to get personal and financial information, like your credit card number or access to your financial services.
For example, one type of smishing scam is when you get a text message that looks like it’s from your bank. The message might say there’s been suspicious activity on your account and that you need to click on a link to verify your identity. If you do click on the link, you’ll be taken to a fake website where you’ll be asked to enter your banking information. Once the scammers have your login information, they have access to clean out your account.
Smishing scams can be very difficult to spot, but there are some telltale signs to look for and steps to take to protect yourself.
One of the easiest ways to protect yourself from smishing scams is to be able to recognize the signs of a smishing text message. Here are some tips:
While you can’t avoid smishing attacks altogether, you can block spam text messages you receive on your mobile phone. iPhone and Android have cybersecurity tools like spam filters and phone number blocking to help protect you from phishing attacks and malicious links.
To set up spam filters on your iPhone:
To set up spam filters on your Android mobile device:

Organizations embrace the public cloud for the agility, scalability, and reliability it offers when running applications. But just as organizations need these capabilities to ensure their applications operate where needed and as needed, they also require their security does the same. Organizations may introduce multiple individual firewalls into their AWS infrastructure to produce this outcome. In theory, this may be a good decision, but in practice—this could lead to asymmetric routing issues. Complex SNAT configuration can mitigate asymmetric routing issues, but this isn’t practical for sustaining public cloud operations. Organizations are looking out for their long-term cloud strategies by ruling out SNAT and are calling for a more reliable and scalable solution for connecting their applications and security for always-on protection.
To solve these challenges, Cisco created stateful firewall clustering with Secure Firewall in AWS.
Firewall clustering for Secure Firewall Threat Defense Virtual provides a highly resilient and reliable architecture for securing your AWS cloud environment. This capability lets you group multiple Secure Firewall Threat Defense Virtual appliances together as a single logical device, known as a “cluster.”
A cluster provides all the conveniences of a single device (management and integration into a network) while taking advantage of the increased throughput and redundancy you would expect from deploying multiple devices individually. Cisco uses Cluster Control Link (CCL) for forwarding asymmetric traffic across devices in the cluster. Clusters can go up to 16 members, and we use VxLAN for CCL.
In this case, clustering has the following roles:
The above diagram explains traffic flow between the client and the server with the insertion of the firewall cluster in the network. Below defines the roles of clustering and how packet flow interacts at each step.
Owner: The Owner is the node in the cluster that initially receives the connection.
Backup Owner: The node that stores TCP/UDP state information received from the Owner so that the connection can be seamlessly transferred to a new owner in case of failure.
Director: The Director is the node in the cluster that handles owner lookup requests from the Forwarder(s).
Forwarder: The Forwarder is a node in the cluster that redirects packets to the Owner.
Fragment Owner: For fragmented packets, cluster nodes that receive a fragment determine a Fragment Owner using a hash of the fragment source IP address, destination IP address, and the packet ID. All fragments are then redirected to the Fragment Owner over Cluster Control Link.
Cisco brought support for AWS Gateway Load Balancer (Figure 2). This feature enables organizations to scale their firewall presence as needed to meet demand (see details here).
Building off the previous figure, organizations can take advantage of the AWS Gateway Load Balancer with Secure Firewall’s clustering capability to evenly distribute traffic at the Secure Firewall cluster. This enables organizations to maximize the benefits of clustering capabilities including increased throughput and redundancy. Figure 3 shows how positioning a Secure Firewall cluster behind the AWS Gateway Load Balancer creates a resilient architecture. Let’s take a closer look at what is going on in the diagram.
Figure 3 shows an Internet user looking to access a workload. Before the user can access the workload, the user’s traffic is routed to Firewall Node 2 for inspection. The traffic flow for this example includes:
User -> IGW -> GWLBe -> GWLB -> Secure Firewall (2) -> GLWB -> GWLBe -> Workload
In the event of failure, the AWS Gateway Load Balancer cuts off existing connections to the failed node, making the above solution non-stateful.
Recently, AWS announced a new feature for their load balancers known as Target Failover for Existing Flows. This feature enables forwarding of existing connections to another target in the event of failure.
Cisco is an early adaptor of this feature and has combined Target Failover for Existing Flows with Secure Firewall clustering capabilities to create the industry’s first stateful cluster in AWS.
Figure 4 shows a firewall failure event and how the AWS Gateway Load Balancer uses the Target Failover for Existing Flows feature to switch the traffic flow from Firewall Node 2 to Firewall Node 3. The traffic flow for this example includes:
User -> IGW -> GWLBe -> GWLB -> Secure Firewall (3) -> GLWB -> GWLBe -> Workload
Organizations need reliable and scalable security to protect always-on applications in their AWS cloud environment. With stateful firewall clustering capabilities from Cisco, organizations can protect their applications while maintaining cloud benefits such as agility, scalability, and reliability.
Cisco Secure Firewall Threat Defense Virtual is available in the AWS marketplace, providing features like firewalling, application visibility & control, IPS, URL filtering, and malware defense. Cisco offers flexible options for firewall licensing, such as pay-as-you-go (PAYG) and bring-your-own-license (BYOL).

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:

Football (or Soccer as we call it in the U.S.) is the most popular sport in the world, with over 3.5 billion fans across the globe. On November 20th, the men’s World Cup kicks off (pun intended) in Qatar. This event, a tournament played by 32 national teams every four years, determines the sport’s world champion. It will also be one of the most-watched sporting events of at least the last four years (since the previous World Cup).
An event with this level of popularity and interest also attracts fraudsters and cyber criminals looking to capitalize on fans’ excitement. Here’s how to spot these scams and stay penalty-free during this year’s tournament.
Phishing is a tool that cybercriminals have used for years now. Most of us are familiar with the telltale signs—misspelled words, poor grammar, and a sender email whose email address makes no sense or whose phone number is unknown. But excitement and anticipation can cloud our judgment. What football fan wouldn’t be tempted to win a free trip to see their home team participate in the ultimate tournament? Cybercriminals are betting that this excitement will cloud fans’ judgment, leading them to click on nefarious links that ultimately download malware or steal personal information.
It’s important to realize that these messages can come via a variety of channels, including email, text messages, (also known as smishing) and other messaging channels like WhatsApp and Telegram. No matter what the source is, it’s essential to remain vigilant and pause to think before clicking links or giving out personal or banking information.
For more information on phishing and how to spot a phisher, see McAfee’s “What is Phishing?” blog.
According to ActionFraud, the UK’s national reporting center for fraud and cybercrime, thousands of people were victims of ticket fraud in 2019—and that’s just in the UK. Ticket fraud is when someone advertises tickets for sale, usually through a website or message board, collects the payment and then disappears, without the buyer ever receiving the ticket.
The World Cup is a prime (and lucrative) target for this type of scam, with fans willing to pay thousands of dollars to see their teams compete. Chances are most people have their tickets firmly in hand (or digital wallet) by now, but if you’re planning to try a last-minute trip, beware of this scam and make sure that you’re using a legitimate, reputable ticket broker. To be perfectly safe, stick with well-known ticket brokers and those who offer consumer protection. Also beware of sites that don’t accept debit or credit cards and only accept payment in the form of bitcoin or wire transfers such as the one on the fake ticket site below:
The red box on the right image shows that the ticket site accepts payment via Bitcoin.
Other red flags to look out for are websites that ask you to contact them to make payment and the only contact information is via WhatsApp.
Let’s be realistic—most of us are going to have to settle for watching the World Cup from the comfort of our own home, or the pub down the street. If you’re watching the tournament online, be sure that you’re using a legitimate streaming service. A quick Google of “FIFA World Cup 2022 Official Streaming” along with your country should get you the information you need to safely watch the event through official channels. The FIFA site itself is also a good source of information.
Illegal streaming sites usually contain deceptive ads and malware which can cause harm to your device.
In countries or regions where sports betting is legal, the 2022 World Cup is expected to drive an increase in activity. There’s no shortage of things to bet on, from a simple win/loss to the exact minute a goal will be scored by a particular player. Everything is subject to wager.
As with our previous examples, this increase in legitimate gambling brings with it an increase in deceptive activity. Online betting scams often start when users are directed to or search for gambling site and end up on a fraudulent one. After placing their bets and winning, users realize that while they may have “won” money, they are unable to withdraw it and are even sometimes asked to deposit even more money to make winnings available, and even then, they still won’t be. By the end of this process, the bettor has lost all their initial money (and then some, potentially) as well as any personal information they shared on the site.
Like other scams, users should be wary of sites that look hastily put together or are riddled with errors. Your best bet (yes, again, pun intended) is to look for an established online service that is approved by your government or region’s gaming commission. Finally, reading the fine print on incentives or bonuses is always a good idea. If something sounds too good to be true, it’s best to double-check.
For more on how you can bet online safely, and for details on how legalized online betting works in the U.S., check out our blog on the topic.
Using a free public Wi-Fi connection is risky. User data on these networks is unprotected, which makes it vulnerable to cyber criminals. Whether you’re traveling to Qatar for a match or watching the them with friends at your favorite pub, if you’re connecting to a public Wi-Fi connection, make sure you use a trusted VPN connection.

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.
