Dan Burke is the director of strategy, risk, and compliance for AppDynamics, a company acquired by Cisco in 2017. Burke and his team are a vital part of the Cisco acquisition process in helping acquired companies adhere to a higher level of cybersecurity. This blog is the fourth in a series focused on M&A cybersecurity, following Shiva Persaud’s post on When It Comes to M&A, Security Is a Journey.
Part of the secret to Cisco’s success is its ability to acquire companies that strengthen its technology portfolio and securely integrate them into the larger organization. From the outside, that process might appear seamless—consider Webex or Duo Security, for instance—but a fruitful acquisition takes tremendous work by multiple cross-functional teams, mainly to ensure the acquired company’s solutions and products meet Cisco’s rigorous security requirements.
“My team is responsible for aligning new acquisitions to Cisco controls to maintain our compliance with SOC2 and FedRAMP, as well as other required certifications,” says Burke.
When Cisco acquires a new company, it conducts an assessment and produces a security readiness plan (SRP) document. The SRP details the identified weaknesses and risks within that company and what they need to fix to meet Cisco standards.
“In the past, my team wouldn’t find out about an acquisition until they received a completed SRP. The downside of this approach was that the assessments and negotiations had been done without input from our group of experts, and target dates for resolution had already been decided on,” shares Burke.
“We needed to be involved in the process before the SRP was created to understand all risks and compliance issues in advance. Now we have a partnership with the Cisco Security and Trust M&A team and know about an acquisition months before we can start working to address risks and other issues—before the SRP is completed and the due dates have been assigned,” Burke adds.
“Another issue resolved in this process change is that Cisco can gain earlier access to the people in the acquired company who know the security risks of their solutions. During acquisitions, people will often leave the company, taking with them their institutional knowledge, resulting in Cisco having to start from scratch to identify and assess the risks and determine how best to resolve them as quickly as possible,” says Burke. “It could be vulnerabilities in physical infrastructure or software code or both. It could be that the company isn’t scanning often enough, or they don’t have SOC 2 or FedRAMP certification yet—or they’re not using Cisco’s tools.”
“Third-party vendors and suppliers can also present an issue,” he adds. “One of the biggest risk areas of any company is outside vendors who have access to a company’s data. It’s vital to identify who these vendors are and understand the level of access they have to data and applications. The earlier we know all these things, the more time we must devise solutions to solve them.”
“Now that I’m in the process earlier, I can build a relationship with the people who have the security knowledge—before they leave. If I can understand their mindset and how all these issues came about, I can help them assimilate more easily into the bigger Cisco family,” says Burke.
The additional benefits of bringing teams in earlier are reduced risk and compliance requirements can be met earlier. It also provides a smoother transition for the company being acquired and ensures they meet the security requirements that customers expect when using their technology solutions.
“Without that early involvement, we might treat a low-risk issue as high risk, or vice versa. The misclassification of risk is extremely dangerous. If you’re treating something as high risk, that’s low risk, and you’re wasting people’s time and money. But if something’s high risk and you’re treating it as low risk, then you’re in danger of harming your company,” Burke shares.
“The key is to involve their risk, compliance, and security professionals from the beginning. I think other companies keep the M&A process so closely guarded, to their detriment. I understand the need for privacy and to make sure deals are confidential but bringing us in earlier was an advantage for the M&A team and us,” Burke adds.
When asked what he thinks makes Cisco successful in M&A, Burke says, “Cisco does an excellent job of assimilating everyone into the larger organization. I have worked at other companies where they kept their acquisitions separate, which means you have people operating separately with different controls for different companies. That’s not only a financial burden but also a compliance headache.”
“That’s why Cisco tries to drive all its acquisitions through our main programs and controls. It makes life easier for everyone in terms of compliance. With Cisco, you have that security confidence knowing that all these companies are brought up to their already very high standards, and you can rely on the fact that they don’t treat them separately. And when an acquisition has vulnerabilities, we identify them, set out a remediation path, and manage the process until those risks are resolved,” Burke concludes.

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!

Microsoft today released updates to fix at least 85 security holes in its Windows operating systems and related software, including a new zero-day vulnerability in all supported versions of Windows that is being actively exploited. However, noticeably absent from this month’s Patch Tuesday are any updates to address a pair of zero-day flaws being exploited this past month in Microsoft Exchange Server.
The new zero-day flaw– CVE-2022-41033 — is an “elevation of privilege” bug in the Windows COM+ event service, which provides system notifications when users logon or logoff. Microsoft says the flaw is being actively exploited, and that it was reported by an anonymous individual.
“Despite its relatively low score in comparison to other vulnerabilities patched today, this one should be at the top of everyone’s list to quickly patch,” said Kevin Breen, director of cyber threat research at Immersive Labs. “This specific vulnerability is a local privilege escalation, which means that an attacker would already need to have code execution on a host to use this exploit. Privilege escalation vulnerabilities are a common occurrence in almost every security compromise. Attackers will seek to gain SYSTEM or domain-level access in order to disable security tools, grab credentials with tools like Mimkatz and move laterally across the network.
Indeed, Satnam Narang, senior staff research engineer at Tenable, notes that almost half of the security flaws Microsoft patched this week are elevation of privilege bugs.
Some privilege escalation bugs can be particularly scary. One example is CVE-2022-37968, which affects organizations running Kubernetes clusters on Azure and earned a CVSS score of 10.0 — the most severe score possible.
Microsoft says that to exploit this vulnerability an attacker would need to know the randomly generated DNS endpoint for an Azure Arc-enabled Kubernetes cluster. But that may not be such a tall order, says Breen, who notes that a number of free and commercial DNS discovery services now make it easy to find this information on potential targets.
Late last month, Microsoft acknowledged that attackers were exploiting two previously unknown vulnerabilities in Exchange Server. Paired together, the two flaws are known as “ProxyNotShell” and they can be chained to allow remote code execution on Exchange Server systems.
Microsoft said it was expediting work on official patches for the Exchange bugs, and it urged affected customers to enable certain settings to mitigate the threat from the attacks. However, those mitigation steps were soon shown to be ineffective, and Microsoft has been adjusting them on a daily basis nearly each day since then.
The lack of Exchange patches leaves a lot of Microsoft customers exposed. Security firm Rapid7 said that as of early September 2022 the company observed more than 190,000 potentially vulnerable instances of Exchange Server exposed to the Internet.
“While Microsoft confirmed the zero-days and issued guidance faster than they have in the past, there are still no patches nearly two weeks out from initial disclosure,” said Caitlin Condon, senior manager of vulnerability research at Rapid7. “Despite high hopes that today’s Patch Tuesday release would contain fixes for the vulnerabilities, Exchange Server is conspicuously missing from the initial list of October 2022 security updates. Microsoft’s recommended rule for blocking known attack patterns has been bypassed multiple times, emphasizing the necessity of a true fix.”
Adobe also released security updates to fix 29 vulnerabilities across a variety of products, including Acrobat and Reader, ColdFusion, Commerce and Magento. Adobe said it is not aware of active attacks against any of these flaws.
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.
It is never too late to start a career in cybersecurity — this may sound cliché, but it holds a lot of truth. If you are passionate about the topic and are ready to put in the work to acquire the skills and knowledge needed, anyone, regardless of educational background, can break into cybersecurity.
At the age of 26, I started a four-year bachelor’s degree in digital forensics. I got introduced to the field by chance after working in data analytics for a few years and taking a college class on criminology. The program that I signed up for was mostly remote, with 80% independent preparation and bi-monthly on-site weekends at the university. I quickly realized that this model of education works great for me — I could read the materials provided by the program at my own pace and use as much external materials to supplement my understanding as needed. While the program was designed for working professionals and classes were spread out over four years, instead of the usual three years for a bachelor’s degree in Germany, it required a lot of discipline to complete the coursework while having a full-time job. Along the way, I learned several things about combining the responsibilities of adult life and achieving the study goals I had set for myself.
Below, I will outline a few recommendations to follow if you would like to break into the security field as an adult learner.
Use visual support to communicate your goals and timeline to others. This makes it easy for them to understand where you stand and why you might pass on the dinner invitation for next weekend.
Small reminders like the one above can help you stay motivated and focused.
One of the first events that I attended as a student was an information day by the German research institute Fraunhofer Institute for Secure Information Technology (SIT). Public institutions like this one tend to offer more affordable events and discount rates for students.
Appreciate the small steps forward and be gentle to your mental health.

Shiva Persaud is the director of security engineering for Cisco. His team is responsible for the Cisco Secure Development Lifecycle (CSDL), a set of practices based on a “secure-by-design” philosophy developed to ensure that security and compliance are top-of-mind in every step of a solution’s lifecycle. This blog is the third in a series focused on M&A cybersecurity, following Jason Button’s post on Demonstrating Trust and Transparency in Mergers and Acquisitions.
One of the most important considerations when Cisco acquires a company, is ensuring that the security posture of the acquisition’s solutions and infrastructure meets the enterprise’s security standards. That can be a tricky proposition and certainly doesn’t happen overnight. In fact, at Cisco, it only comes about thanks to the efforts of a multitude of people working hard behind the scenes.
“The consistent message is that no matter where a product is in its security journey, from inception to end-of-life activities, there’s still a lot of work that can happen to lead to a better security outcome,” says Persaud.
While Persaud and his team work within Cisco on all the company’s products and solutions, they also play a critical role in maintaining security standards in Cisco’s mergers and acquisitions (M&A) work.
Simply put, Persaud’s team is tasked with identifying the security risks posed by an acquisition’s technology and helping teams mitigate those risks.
“It starts with a risk assessment where we ask ourselves what an attacker would do to compromise this specific technology,” says Persaud. “What are the industry best practices for securing this type of technology? What do our customers expect this technology to provide from a security perspective? And once we have those risks enumerated, we prioritize them to decide which is the most important to take care of first.”
To anticipate where a hacker might find vulnerabilities and the actions they might take, the CSDL team must put themselves in that attack mindset. Fortunately for Persaud, his interest in computer security started as early as middle school. “It just kind of grew from there,” he says. “For many folks I’ve worked with and hired over the years, it’s a similar situation.”
That lifelong interest and experience work to the team’s advantage. They take a risk-based approach to security, in which they identify all the issues that need to be fixed and then rate them based on the likelihood of occurrence and seriousness of the results of an attack. Those ratings inform their decisions on which issues to fix first.
“We come up with ways to go mitigate those risks and co-author a plan called the Security Readiness Plan, or SRP,” Persaud says. “Then we partner with teams to take that plan and execute it over time.”
In alignment with CSDL’s continuous approach to security throughout a solution’s lifecycle, Persaud says that “security is a journey, so the workflow to finish the secure development lifecycle never ends.”
While initial onboarding of an acquired company—including completion of the initial risk assessment and the SRP—typically ends within several months of the acquisition. Persaud adds, “The work continues as the technology is integrated into a larger tech stack or as it’s modified and sold as a standalone offering to our customers.” As the solution or technology evolves and begins to include new features and functionalities, the CSDL work continues to make sure those features are secure as well.
That work can have its obstacles. Persaud says that one of the primary challenges his team deals with is cutting through the flurry of activity and bids for the acquisition’s attention that come pouring in from all sides. It’s a crazy time for both Cisco and the acquisition, with many important tasks at the top of everyone’s to-do lists. “Not just in the security realm,” says Persaud,” but in many other areas, too. So being able to get the acquisition to focus on security in a meaningful way in the context of everything else that’s happening is a major challenge.”
Another challenge is dealing with acquisitions that might not have much security expertise on their original team. That means they’re not able to give Persaud’s team much help in determining where security risks lie and how serious they are—so Cisco’s engineers have a lot more investigative work to do.
When asked what advice he would give to organizations that want to maintain a good security posture when acquiring another company, Persaud names three key factors.
To succeed in M&A security, it’s critical that the organization’s board of directors, CEO, and all subsequent levels of management support and be committed to meeting a high level of security standards and outcomes. The remaining management of the acquisition also needs to be on board with the security commitment, and both organizations should make sure that all employees recognize that commitment and support. If management support is not there, the work ultimately won’t get done. It can be difficult and time-consuming and without companywide recognition of its key importance, it won’t get prioritized, and it will get lost in the myriad of other things that all the teams have to do.
The issue of security can get really complicated, very quickly. Persaud says it’s smart to find industry standards and best practices that already exist and are available to everyone, “so you’re not reinventing the wheel—or more concerning, reinventing the wheel poorly.”
Where to look for those industry standards will vary, depending on the technology stack that needs to be secured. “If you are interested in securing a web application,” says Persaud, “then starting with the OWASP Top Ten list is a good place to start. If you are selling a cloud offer or cloud service, then look at the Cloud Security Alliance’s Cloud Controls Matrix (CCM) or the Cisco Cloud Controls Framework.”
One way to think of it, Persaud says, is that there are a variety of security frameworks certain customers will need a company to adhere to before they can use their solutions. Think frameworks like FedRAMP, SOC-2, Common Criteria, or FIPS.
“You can align your product security work to those frameworks as a baseline and then build on top of them to make technology more resilient.” It’s a great place to start.
It’s essential that an organization be very clear on what it wants to accomplish when it comes to ensuring security of an acquisition’s solutions and infrastructure. This will help it avoid “trying to boil the whole ocean,” says Persaud.
Persaud and his team talk about working up to security fitness the way a runner would start with a 5K and work up to an Ironman competition. “You take progressive steps towards improving,” he says. “You’re very explicit about what milestones of improvement you’ll encounter on your journey of good security.”
Persaud says Cisco is uniquely positioned to help organizations maintain security standards when acquiring other companies. He points to three critical differentiators.
“The level of visibility and support that we have for security at Cisco, starts with our board of directors and our CEO, and then throughout the organization,” says Persaud. “This is a very special and unique situation that allows us to do a lot of impactful work from a security perspective,”
Cisco has long been adamant about security that’s built in from the ground up and not bolted on as an afterthought. It’s the reason the CSDL exists, as well as the Cisco Security & Trust Organization and the many, many teams that work every day to infuse security and privacy awareness into every product, service, and solution—including the technology and infrastructure of newly acquired companies.
Once Persaud’s team has identified and assessed the security risks of an acquisition, his and other teams go about helping the acquisition address and mitigate those risks. Cisco provides a set of common building blocks or tools that teams can use to improve the security posture of an acquisition.
“We have secure libraries that teams can integrate into their code base to help them do certain things securely, so that the individual teams don’t have to implement that security functionality from scratch,” says Persaud. “And Cisco produces certain pieces of hardware that can be leveraged across our product lines, such as secure boot and secure storage.”
“Cisco’s operations stack also has various services acquisitions can use,” says Persaud. “An example of this comes from our Security Vulnerability and Incident Command team (SVIC). They provide logging capabilities that cloud offers at Cisco can leverage to do centralized logging, and then monitor those logs. SVIC also offers a security vulnerability scanning service so individual teams don’t have to do it independently.”
Another critical building block is Persaud’s team and their expertise. They act as a valuable resource that teams can consult when they want to build a new feature securely or improve the security of an existing feature.
Persaud concludes, “Cisco has an extremely strong and active security community where teams can ask questions, gain insights, give guidance, troubleshoot issues, share ideas and technology, and discuss emerging security topics. The community is committed to helping others instead of competing against each other. Members have the mindset of enriching the overall approach to security at Cisco and learning from any source they can to make things continually better.

When U.S. consumers have their online bank accounts hijacked and plundered by hackers, U.S. financial institutions are legally obligated to reverse any unauthorized transactions as long as the victim reports the fraud in a timely manner. But new data released this week suggests that for some of the nation’s largest banks, reimbursing account takeover victims has become more the exception than the rule.
The findings came in a report released by Sen. Elizabeth Warren (D-Mass.), who in April 2022 opened an investigation into fraud tied to Zelle, the “peer-to-peer” digital payment service used by many financial institutions that allows customers to quickly send cash to friends and family.
Zelle is run by Early Warning Services LLC (EWS), a private financial services company which is jointly owned by Bank of America, Capital One, JPMorgan Chase, PNC Bank, Truist, U.S. Bank, and Wells Fargo. Zelle is enabled by default for customers at over 1,000 different financial institutions, even if a great many customers still don’t know it’s there.
Sen. Warren said several of the EWS owner banks — including Capital One, JPMorgan and Wells Fargo — failed to provide all of the requested data. But Warren did get the requested information from PNC, Truist and U.S. Bank.
“Overall, the three banks that provided complete data sets reported 35,848 cases of scams, involving over $25.9 million of payments in 2021 and the first half of 2022,” the report summarized. “In the vast majority of these cases, the banks did not repay the customers that reported being scammed. Overall these three banks reported repaying customers in only 3,473 cases (representing nearly 10% of scam claims) and repaid only $2.9 million.”
Importantly, the report distinguishes between cases that involve straight up bank account takeovers and unauthorized transfers (fraud), and those losses that stem from “fraudulently induced payments,” where the victim is tricked into authorizing the transfer of funds to scammers (scams).
A common example of the latter is the Zelle Fraud Scam, which uses an ever-shifting set of come-ons to trick people into transferring money to fraudsters. The Zelle Fraud Scam often employs text messages and phone calls spoofed to look like they came from your bank, and the scam usually relates to fooling the customer into thinking they’re sending money to themselves when they’re really sending it to the crooks.
Here’s the rub: When a customer issues a payment order to their bank, the bank is obligated to honor that order so long as it passes a two-stage test. The first question asks, Did the request actually come from an authorized owner or signer on the account? In the case of Zelle scams, the answer is yes.
Trace Fooshee, a strategic advisor in the anti money laundering practice at Aite-Novarica, said the second stage requires banks to give the customer’s transfer order a kind of “sniff test” using “commercially reasonable” fraud controls that generally are not designed to detect patterns involving social engineering.
Fooshee said the legal phrase “commercially reasonable” is the primary reason why no bank has much — if anything — in the way of controlling for scam detection.
“In order for them to deploy something that would detect a good chunk of fraud on something so hard to detect they would generate egregiously high rates of false positives which would also make consumers (and, then, regulators) very unhappy,” Fooshee said. “This would tank the business case for the service as a whole rendering it something that the bank can claim to NOT be commercially reasonable.”
Sen. Warren’s report makes clear that banks generally do not pay consumers back if they are fraudulently induced into making Zelle payments.
“In simple terms, Zelle indicated that it would provide redress for users in cases of unauthorized transfers in which a user’s account is accessed by a bad actor and used to transfer a payment,” the report continued. “However, EWS’ response also indicated that neither Zelle nor its parent bank owners would reimburse users fraudulently induced by a bad actor into making a payment on the platform.”
Still, the data suggest banks did repay at least some of the funds stolen from scam victims about 10 percent of the time. Fooshee said he’s surprised that number is so high.
“That banks are paying victims of authorized payment fraud scams anything at all is noteworthy,” he said. “That’s money that they’re paying for out of pocket almost entirely for goodwill. You could argue that repaying all victims is a sound strategy especially in the climate we’re in but to say that it should be what all banks do remains an opinion until Congress changes the law.”
However, when it comes to reimbursing victims of fraud and account takeovers, the report suggests banks are stiffing their customers whenever they can get away with it. “Overall, the four banks that provided complete data sets indicated that they reimbursed only 47% of the dollar amount of fraud claims they received,” the report notes.
How did the banks behave individually? From the report:
-In 2021 and the first six months of 2022, PNC Bank indicated that its customers reported 10,683 cases of unauthorized payments totaling over $10.6 million, of which only 1,495 cases totaling $1.46 were refunded to consumers. PNC Bank left 86% of its customers that reported cases of fraud without recourse for fraudulent activity that occurred on Zelle.
-Over this same time period, U.S. Bank customers reported a total of 28,642 cases of unauthorized transactions totaling over $16.2 million, while only refunding 8,242 cases totaling less than $4.7 million.
-In the period between January 2021 and September 2022, Bank of America customers reported 81,797 cases of unauthorized transactions, totaling $125 million. Bank of America refunded only $56.1 million in fraud claims – less than 45% of the overall dollar value of claims made in that time.
–Truist indicated that the bank had a much better record of reimbursing defrauded customers over this same time period. During 2021 and the first half of 2022, Truist customers filed 24,752 unauthorized transaction claims amounting to $24.4 million. Truist reimbursed 20,349 of those claims, totaling $20.8 million – 82% of Truist claims were reimbursed over this period. Overall, however, the four banks that provided complete data sets indicated that they reimbursed only 47% of the dollar amount of fraud claims they received.
Fooshee said there has long been a great deal of inconsistency in how banks reimburse unauthorized fraud claims — even after the Consumer Financial Protection Bureau (CPFB) came out with guidance on what qualifies as an unauthorized fraud claim.
“Many banks reported that they were still not living up to those standards,” he said. “As a result, I imagine that the CFPB will come down hard on those with fines and we’ll see a correction.”
Fooshee said many banks have recently adjusted their reimbursement policies to bring them more into line with the CFPB’s guidance from last year.
“So this is heading in the right direction but not with sufficient vigor and speed to satisfy critics,” he said.
Seth Ruden is a payments fraud expert who serves as director of global advisory for digital identity company BioCatch. Ruden said Zelle has recently made “significant changes to its fraud program oversight because of consumer influence.”
“It is clear to me that despite sensational headlines, progress has been made to improve outcomes,” Ruden said. “Presently, losses in the network on a volume-adjusted basis are lower than those typical of credit cards.”
But he said any failure to reimburse victims of fraud and account takeovers only adds to pressure on Congress to do more to help victims of those scammed into authorizing Zelle payments.
“The bottom line is that regulations have not kept up with the speed of payment technology in the United States, and we’re not alone,” Ruden said. “For the first time in the UK, authorized payment scam losses have outpaced credit card losses and a regulatory response is now on the table. Banks have the choice right now to take action and increase controls or await regulators to impose a new regulatory environment.”
Sen. Warren’s report is available here (PDF).
There are, of course, some versions of the Zelle fraud scam that may be confusing financial institutions as to what constitutes “authorized” payment instructions. For example, the variant I wrote about earlier this year began with a text message that spoofed the target’s bank and warned of a pending suspicious transfer.
Those who responded at all received a call from a number spoofed to make it look like the victim’s bank calling, and were asked to validate their identities by reading back a one-time password sent via SMS. In reality, the thieves had simply asked the bank’s website to reset the victim’s password, and that one-time code sent via text by the bank’s site was the only thing the crooks needed to reset the target’s password and drain the account using Zelle.
None of the above discussion involves the risks affecting businesses that bank online. Businesses in the United States do not enjoy the same fraud liability protection afforded to consumers, and if a banking trojan or clever phishing site results in a business account getting drained, most banks will not reimburse that loss.
This is why I have always and will continue to urge small business owners to conduct their online banking affairs only from a dedicated, access restricted and security-hardened device — and preferably a non-Windows machine.
For consumers, the same old advice remains the best: Watch your bank statements like a hawk, and immediately report and contest any charges that appear fraudulent or unauthorized.
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.

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!

The joy of purchasing a new device is liberating. Now you can work, learn, and play faster — along with enjoying ample storage space. So, the last thing you’d expect is your apparently safe device being exposed to vulnerabilities, or “bloat.”
Exposure to unwanted software can derail its performance and hog its storage within a few months of usage. In technical terms, such pieces of software are referred to as bloatware. Bloatware has the potential to attack PCs with Microsoft systems and Android devices. It can also attack Apple iPhones and Macs although their systems tend to be built with a bit more protection.
This article defines bloatware, offers common examples, explains how to identify it, and discusses its impact on your computer’s security.
Bloatware, also called Junkware or Potentially Unwanted Programs (PUP), are third-party programs that slow down the performance of your device and lay it bare to cybersecurity risks.
Manufacturers initially introduced bloatware to provide users with more utility, but the programs led to device issues. Software programs that identify as bloatware run in the background, and locating them is not child’s play.
Bloatware finds its way into your device in two ways: it comes pre-installed or through programs downloaded from the internet. Lenovo‘s Superfish bloatware scandal from 2015 explains how bloatware can harm your devices.
Common examples of bloatware apps include:
As a piece of good advice, it is best to uninstall such apps when of no use — whether on your Android smartphone, Windows computer, or an iOS device.
Performance degradation is a common symptom of a device carrying bloatware. Extended boot-up times, clogged storage, and startup delays are common occurrences. Let’s review some programs that may also be bloatware:
Here’s how to identify bloatware:
As mentioned, not all bloatware is a threat to your device. Some may be useful and can be removed easily. But a major chunk of bloatware is known to slow down your computer.
Bloatware eats up a good chunk of the disk space or hard drive as it runs in the background, and it drains the battery life. Bloatware that isn’t removed quickly may clog your device with annoying ads. These ads can pose a security threat or even corrupt your operating system.
Sadly, it can be a challenge to uninstall bloatware because it finds its way back into the device — sometimes even after it has been deleted. In some cases, it may even redirect you to fake bloatware removal websites and offer malicious removal tools. Such websites ask you to install a new program to remove the previous one, trapping your device further. Unfortunately, there are no secret hacks to stop it from finding a way into your system.
Pro tip: Anytime you download a program or software, be sure it’s from an official source (like a secured website, the Google Play Store, or the Apple App Store). Installing a program from a suspicious website can put your device at risk, as the program can download bundles of other programs on the back end without your knowledge.
Windows 10 comes with a special refresh tool to remove any bloatware disguised as user-installed programs. This tool can bring your PC back to a clean slate. It’s important to check your hard drive beforehand, as it can also remove licenses.
Bloatware can be both harmful and annoying. New devices need full-fledged protection so they can last longer. The answer to your bloatware woes is an antivirus program. It safeguards your computer from dangerous security threats and prevents accidental downloads, so malicious bloatware or malware can’t access your device.
Bloatware can compromise your online safety and security. McAfee+’s protection package is the ideal investment for your new device, so you can work without any hassles or doubts.
McAfee+ enables a top-tier level of online security with full protection from pesky software programs like bloatware. Additionally, you get access to antivirus software for unlimited devices, lost wallet protection, a secure VPN, personal data clean-ups, and more.

It’s hard to imagine a world without cellphones. Whether it be a smartphone or a flip phone, these devices have truly shaped the late 20th century and will continue to do so for the foreseeable future. But while users have become accustomed to having almost everything they could ever want at fingertips length, cybercriminals were busy setting up shop. To trick unsuspecting users, cybercriminals have set up crafty mobile threats – some that users may not even be fully aware of. These sneaky cyberthreats include SMSishing, fake networks, malicious apps, and grayware, which have all grown in sophistication over time. This means users need to be equipped with the know-how to navigate the choppy waters that come with these smartphone-related cyberthreats. Let’s get started.
If you use email, then you are probably familiar with what phishing is. And while phishing is commonly executed through email and malicious links, there is a form of phishing that specifically targets mobile devices called SMSishing. This growing threat allows cybercriminals to utilize messaging apps to send unsuspecting users a SMSishing message. These messages serve one purpose – to obtain personal information, such as logins and financial information. With that information, cybercriminals could impersonate the user to access banking records or steal their identity.
While this threat was once a rarity, it’s rise in popularity is two-fold. The first aspect being that users have been educated to distrust email messages and the second being the rise in mobile phone usage throughout the world. Although this threat shows no sign of slowing down, there are ways to avoid a cybercriminal’s SMSishing hooks. Get started with these tips:
Public and free Wi-Fi is practically everywhere nowadays, with some destinations even having city-wide Wi-Fi set up. But that Wi-Fi users are connecting their mobile device to may not be the most secure, given cybercriminals can exploit weaknesses in these networks to intercept messages, login credentials, or other personal information. Beyond exploiting weaknesses, some cybercriminals take it a step further and create fake networks with generic names that trick unsuspecting users into connecting their devices. These networks are called “evil-twin” networks. For help in spotting these imposters, there are few tricks the savvy user can deploy to prevent an evil twin network from wreaking havoc on their mobile device:
Fake apps have become a rampant problem for Android and iPhone users alike. This is mainly in part due to malicious apps hiding in plain sight on legitimate sources, such as the Google Play Store and Apple’s App Store. After users download a faulty app, cybercriminals deploy malware that operates in the background of mobile devices which makes it difficult for users to realize anything is wrong. And while users think they’ve just downloaded another run-of-the-mill app, the malware is hard at work obtaining personal data.
In order to keep sensitive information out of the hands of cybercriminals, here are a few things users can look for when they need to determine whether an app is fact or fiction:
With so many types of malware out in the world, it’s hard to keep track of them all. But there is one in particular that mobile device users need to be keenly aware of called grayware. As a coverall term for software or code that sits between normal and malicious, grayware comes in many forms, such as adware, spyware or madware. While adware and spyware can sometimes operate simultaneously on infected computers, madware — or adware on mobile devices — infiltrates smartphones by hiding within rogue apps. Once a mobile device is infected with madware from a malicious app, ads can infiltrate almost every aspect on a user’s phone. Madware isn’t just annoying; it also is a security and privacy risk, as some threats will try to obtain users’ data. To avoid the annoyance, as well as the cybersecurity risks of grayware, users can prepare their devices with these cautionary steps:
The post Cybercrime’s Most Wanted: Four Mobile Threats that Might Surprise You appeared first on McAfee Blog.
Happy Cybersecurity Awareness Month!
Every October, the National Cybersecurity Alliance selects a theme around which to publish extensive awareness resources and practical tips to help you improve your cybersecurity.1 This year’s theme is “It’s easy to stay safe online.” With the number of cyberthreats and breaches dominating the headlines, it can seem like a Herculean task to cover all your bases; however, with just four easy habits, you can actually protect yourself against a large percentage of these threats!
Don’t be scared of hackers, phishers, or cybercriminals this month. Leave that to the ghosts, ghouls, and your upcoming holiday social calendar.
Multifactor authentication (MFA) is an excellent way to frustrate cybercriminals attempting to break into your online accounts. MFA means that you need more than a username and password to log in, such as a one-time code sent to by email, text, or through an authentication app or a face or fingerprint scan. This adds an extra layer of security, because a thief would have to have access to your device, your email, or be able to trick a biometric reader to get into your online account.
Most online sites offer the option to turn on MFA. While it may add an extra few seconds to the login process, it’s well worth it. Username and password combinations can be up for sale on the dark web following a breach. With these in hand, a cybercriminal could then help themselves to your online bank account, online medical records, and possibly your identity. When an account is secured with MFA, a criminal may quickly move on to another target that’s easier to crack.
Most sites won’t even let you proceed with creating an account if you don’t have a strong enough password. A strong password is one with a mix of capital and lowercase letters, numbers, and special characters. What also makes for an excellent password is one that’s unique. Reusing passwords can be just as risky as using “password123” or your pet’s name plus your birthday as a password. A reused password can put all your online accounts at risk, due to a practice called credential stuffing. Credential stuffing is a tactic where a cybercriminal attempts to input a stolen username and password combination in dozens of random websites and to see which doors it opens.
Remembering a different password for each of your online accounts is almost an impossible task. Luckily, password managers make it so you only have to remember one password ever again! Password managers, like the one available in McAfee+. safeguard all your passwords in one secure desktop extension or cellphone app that you can use anywhere. McAfee+ is secured with one of the most secure encryption algorithms available, and multifactor authentication is always standard.
It’s best to create passwords or passphrases that have a secret meaning that only you know. Stay away from using significant dates, names, or places, because those are easier to guess. You can also leave it up to your password manager to randomly generate a password for you. The resulting unintelligible jumble of numbers, letters, and symbols is virtually impossible for anyone to guess.
Software update notifications always seem ping on the outskirts of your desktop and mobile device at the most inconvenient times. What’s more inconvenient though is having your device hacked. Another easy tip to improve your cybersecurity is to update your device software whenever upgrades are available. Most software updates include security patches that smart teams have created to foil cybercriminals. The more outdated your apps or operating system is, the more time criminals have had to work out ways to infiltrate them.
Consider enabling automatic updates on all your devices. Many major updates occur in the early hours of the morning, meaning that you’ll never know your devices were offline. You’ll just wake up to new, secure software!
You’ve likely already experienced a phishing attempt, whether you were aware of it or not. Phishing is a common tactic used to eke personal details from unsuspecting or trusting people. Phishers often initiate contact through texts, emails, or social media direct messages, and they aim to get enough information to hack into your online accounts or to impersonate you.
Luckily, it’s usually easy to identify a phisher. Here are a few tell-tale signs for be on the lookout for:
Never engage with a phishing attempt. Do not forward the message or respond to them and never click on any links included in their message. The links could direct to malicious sites that could infect your device with malware or spyware.
Before you delete the message, block the sender, mark the message as junk, and report the phisher. Reporting can go a long way toward hopefully preventing the phisher from targeting someone else.
The best complement to your newfound excellent cyberhabits is a toolbelt of excellent services to patch any holes in your defense. McAfee+ includes all the services you need to boost your peace of mind about your online identity and privacy. You can surf public Wi-Fis safely with its secure VPN, protect your device with antivirus software, scan risky sites for your personally identifiable information, and more!
This October, make a commitment to improving your cybersecurity with the guidance of the National Cybersecurity Alliance and McAfee.

Malicious software, or “malware,” refers to any program designed to infect and disrupt computer systems and networks. The risks associated with a malware infection can range from poor device performance to stolen data.
However, thanks to their closed ecosystem, built-in security features, and strict policies on third-party apps, Apple devices tend to be less prone to malware infections compared to their Android counterparts. But it’s important to note that they’re not completely without vulnerabilities.
Several iPhone viruses could infect your smartphone and affect its functionality, especially if you jailbreak your iPhone (that is, opening your iOS to wider features, apps, and themes).
This article covers how you can detect malware infections and how to remove viruses from your device so you can get back to enjoying the digital world.
Malware can affect your iPhone in a variety of ways. Here are a few telltale signs that your iPhone might have an unwelcome visitor.
If you notice any of the signs above, it’s a good idea to check for malware. Here are some steps you can take.
If you’ve confirmed malware on your iPhone, don’t worry. There’s still time to protect yourself and your data. Below is an action plan you can follow to remove malware from your device.
In many cases, hackers exploit outdated versions of iOS to launch malware attacks. If you don’t have the latest version of your operating system, it’s a good idea to update iOS to close this potential vulnerability. Just follow these steps:
It might sound simple, but restarting your device can fix certain issues. The system will restart on its own when updating the iOS. If you already have the latest version, restart your iPhone now.
If updating the iOS and restarting your device didn’t fix the issue, try clearing your phone’s browsing history and data. If you’re using Safari, follow these steps:
Keep in mind that the process is similar for Google Chrome and most other popular web browsers.
Malicious software, such as spyware and ransomware, often end up on phones by masquerading as legitimate apps. To err on the side of caution, delete any apps that you don’t remember downloading or installing.
The option to restore to a previous backup is one of the most valuable features found on the iPhone and iPad. Essentially, this allows you to restore your device to an iCloud backup made before the malware infection.
Here’s how:
If none of the steps above solves the problem, a factory reset might be the next order of business. Restoring your phone to factory settings will reset it to its out-of-factory configuration, deleting all of your apps, content, and settings in the process and replacing them with original software only.
To factory reset your iPhone, follow these steps:
The best way to protect your iOS device is to avoid malware in the first place. Follow these security measures to safeguard your device:
If you have an iPhone and are like most other people, you probably use your device for almost everything you do online. And while it’s amazing to have the internet in the palm of your hands, it’s also important to be aware of online threats like malware, which can put your digital life at risk.

With “See Yourself in Cyber” as the theme for this year’s Cybersecurity Awareness Month, the focus is on you with a look at several quick ways you can quickly get safer online.
Now in its 21st year, Cybersecurity Awareness Month marks a long-standing collaboration between the U.S. government and private industry. It’s aim, empower people to protect themselves from digital forms of crime. And that stands as a good reminder. Phishing attacks, malware, and the other threats we regularly talk about in our blog are indeed forms of crime. And where there’s crime, there’s a person behind it.
It can be easy to lose sight of that, particularly as the crook on the other end of the attack is hiding behind a computer. Cybercrime can feel anonymous that way, yet it’s anything but. Whether a single bad actor or as part of a large crime organization, people power cybercrime.
Yet just as you secure your home to prevent yourself from becoming a victim of a criminal, you can also secure your digital life to prevent yourself from becoming a victim of cybercriminal.
You have plenty of places where you can start, and they’re all good ones. Even a handful of the simplest measures can significantly decrease your risk. Better yet, several take far less time to put into place than you might think, while yet more work automatically once you implement them—making them a sort of “set it and forget it” security measure.
With that, this five-step list can get you going:
Strong, unique passwords offer another primary line of defense. Yet with all the accounts we have floating around, juggling dozens of strong and unique passwords can feel like a task—thus the temptation to use (and re-use) simpler passwords. Hackers love this because one password can be the key to several accounts. Instead, try a password manager that can create those passwords for you and safely store them as well. Comprehensive security software will include one, and McAfee also offers a free service with True Key.
Updates do all kinds of great things for gaming, streaming, and chatting apps, like add more features and functionality over time. Updates do something else—they make those apps more secure. Hackers will hammer away at apps to find or create vulnerabilities, which can steal personal info or compromise the device itself. Updates will often include security improvements, in addition to performance improvements.
For your computers and laptops:
For your smartphones:
For your smartphone apps:
Often overlooked is the humble browser. Yet if you think about it, the browser is one of the apps we use most often. Particularly on our desktops. It takes us shopping, to shows, the bank, and even work. Hackers realize that, which is why they love targeting browsers. Whether it’s through vulnerabilities in the code that runs the browser, injecting malicious code into a browser session, or any one of several other attack vectors, hackers will try to find a way to compromise computers via the browser.
One of the best ways to keep your browser safe is to keep it updated. By updating your browser, you’ll get the latest in features and functionality in addition to security fixes that can prevent attacks from hackers. It’s a straightforward process, and this article will show you can set your browser to automatically update.
Whether they come by way of an email, text, direct message, or as bogus ads on social media and in search, phishing attacks remain popular with cybercriminals. Across their various forms, the intent remains the same—to steal personal or account information by posing as a well-known company, organization, or even someone the victim knows. And depending on the information that gets stolen, it can result in a drained bank account, a hijacked social media profile, or any number of different identity crimes. What makes some phishing attacks so effective is how some hackers can make the phishing emails and sites they use look like the real thing, so learning how to spot phishing attacks has become a valuable skill nowadays. Additionally, comprehensive online protection software will include web protection that can spot bogus links and sites and warn you away from them, even if they look legit.
Some signs of a phishing attack include:
Email addresses that slightly alter the address of a trusted brand name so it looks close at first glance.
Again, this can take a sharp eye to spot. When you get emails like these, take a moment to scrutinize them and certainly don’t click on any links.
Another way you can fight back against crooks who phish is to report them. Check out ReportFraud.ftc.gov, which shares reports of phishing and other fraud with law enforcement. Taken together with other reports, your information can aid an investigation and help bring charges on a cybercriminal or an organized ring.
Chances are you’re using multi-factor authentication (MFA) on a few of your accounts already, like with your bank or financial institutions. MFA provides an additional layer of protection that makes it much more difficult for a hacker or bad actor to compromise your accounts even if they know your password and username. It’s quite common nowadays, where an online account will ask you to use an email or a text to your smartphone to as part of your logon process. If you have MFA as an option when logging into your accounts, strongly consider using it.
This list can get you started, and you can take even more steps now that you’re rolling. Keep dropping by our blog for more ways you can make yourself safer, such as on social media, your smartphone, in app stores, and more. Visit us any time!
The post See Yourself in Cyber – Five Quick Ways You Can Quickly Get Safer Online appeared first on McAfee Blog.
Microsoft Corp. is investigating reports that attackers are exploiting two previously unknown vulnerabilities in Exchange Server, a technology many organizations rely on to send and receive email. Microsoft says it is expediting work on software patches to plug the security holes. In the meantime, it is urging a subset of Exchange customers to enable a setting that could help mitigate ongoing attacks.
In customer guidance released Thursday, Microsoft said it is investigating two reported zero-day flaws affecting Microsoft Exchange Server 2013, 2016, and 2019. CVE-2022-41040, is a Server-Side Request Forgery (SSRF) vulnerability that can enable an authenticated attacker to remotely trigger the second zero-day vulnerability — CVE-2022-41082 — which allows remote code execution (RCE) when PowerShell is accessible to the attacker.
Microsoft said Exchange Online has detections and mitigation in place to protect customers. Customers using on-premises Microsoft Exchange servers are urged to review the mitigations suggested in the security advisory, which Microsoft says should block the known attack patterns.
Vietnamese security firm GTSC on Thursday published a writeup on the two Exchange zero-day flaws, saying it first observed the attacks in early August being used to drop “webshells.” These web-based backdoors offer attackers an easy-to-use, password-protected hacking tool that can be accessed over the Internet from any browser.
“We detected webshells, mostly obfuscated, being dropped to Exchange servers,” GTSC wrote. “Using the user-agent, we detected that the attacker uses Antsword, an active Chinese-based opensource cross-platform website administration tool that supports webshell management. We suspect that these come from a Chinese attack group because the webshell codepage is 936, which is a Microsoft character encoding for simplified Chinese.”
GTSC’s advisory includes details about post-compromise activity and related malware, as well as steps it took to help customers respond to active compromises of their Exchange Server environment. But the company said it would withhold more technical details of the vulnerabilities for now.
In March 2021, hundreds of thousands of organizations worldwide had their email stolen and multiple backdoor webshells installed, all thanks to four zero-day vulnerabilities in Exchange Server.
Granted, the zero-day flaws that powered that debacle were far more critical than the two detailed this week, and there are no signs yet that exploit code has been publicly released (that will likely change soon). But part of what made last year’s Exchange Server mass hack so pervasive was that vulnerable organizations had little or no advance notice on what to look for before their Exchange Server environments were completely owned by multiple attackers.
Microsoft is quick to point out that these zero-day flaws require an attacker to have a valid username and password for an Exchange user, but this may not be such a tall order for the hackers behind these latest exploits against Exchange Server.
Steven Adair is president of Volexity, the Virginia-based cybersecurity firm that was among the first to sound the alarm about the Exchange zero-days targeted in the 2021 mass hack. Adair said GTSC’s writeup includes an Internet address used by the attackers that Volexity has tied with high confidence to a China-based hacking group that has recently been observed phishing Exchange users for their credentials.
In February 2022, Volexity warned that this same Chinese hacking group was behind the mass exploitation of a zero-day vulnerability in the Zimbra Collaboration Suite, which is a competitor to Microsoft Exchange that many enterprises use to manage email and other forms of messaging.
If your organization runs Exchange Server, please consider reviewing the Microsoft mitigations and the GTSC post-mortem on their investigations.
In the fall of 2021, cryptocurrency value skyrocketed. Ethereum and Bitcoin had their highest values ever, causing a huge stir in interest in online currencies from experts, hobbyists and newbies alike … and in cybercriminals seeking huge paydays. Since then, cryptocurrency value has cooled, as has the public’s opinion about whether it’s worth the risk. Huge cryptohacking events dominate the headlines, leaving us to wonder: Is cryptocurrency losing its credibility?
In this article, you’ll learn about recent unfortunate crypto hacks and a few cryptocurrency security tips to help you avoid a similar misfortune.
A crypto wallet is the software or the physical device that stores the public and private keys to your cryptocurrency. A public key is the string of letters and numbers that people swap with each other in crypto transactions. It’s ok to share a public key with someone you trust. Your private key, however, must remain private — think of it like the password that secures your online bank account. Just like your actual wallet, if it falls into the wrong hands, you can lose a lot of money.
A malware called Mars Stealer infiltrated several crypto wallet browser extensions, including the popular MetaMask. The malware stole private keys and then erased its tracks to mask that it had ever gained entry to the wallet.1
One way to completely avoid a breach to your software crypto wallet is to opt for a hardware wallet. A hardware wallet is a physical device that can only be opened with a PIN. But there is some risk involved with a hardware wallet: if you drop it down the drain, all your crypto is gone. If you forget your wallet PIN, there is no customer service chatbot that can help you remember it. You are solely responsible for keeping track of it. For those who are confident in their hardware’s hiding spot and their personal organizational skills, they can benefit from its added security.
For anyone less sure of their ability to keep track of a hardware wallet, a software wallet is a fine alternative, though always been on alert of software wallet hacks. Keep an eye on crypto news and be ready to secure your software at a moment’s notice. Measures include un-downloading browser extensions, changing passwords, or transferring your crypto assets to another software wallet.
In the case of the Mars Stealer malware that affected MetaMask, being careful about visiting secure sites and only clicking on trustworthy links could’ve helped prevent it. Mars Stealer made its way onto people’s devices after they clicked on an infected link or visited a risky website. Stick to websites you know you can trust and consider springing for well-known streaming services and paying for software instead of torrenting from free sources.
Cryptocurrency enthusiasts often spread their crypto investments across various currency types and blockchain environments. Software known as a bridge can link numerous accounts and types, making it easier to send currency.
The cross-chain bridge Horizon experienced was on its Harmony blockchain, where a hacker stole about $100 million in Ethereum and tokens. The hacker stole two private keys, with which they could then validate this huge transaction into their own wallet. To hopefully prevent this from happening in the future, Horizon now requires more than just two validators.2
According to one report, in 2022, 69% of all cryptocurrency losses have occurred in bridge attacks.3 If you exchange cryptocurrencies with other users and have various accounts, it’s almost inevitable that you’ll use bridge software. To keep your assets safe, make sure to extensively research any bridge before trusting it. Take a look at their security protocols and how they’ve responded to past breaches, if applicable.
In the case of Horizon, the stolen private keys were encrypted with a passphrase and with a key management service, which follows best practices. Make sure that you always defend your private keys and all your cryptocurrency-related accounts with multi-factor authentication. Even though it may not 100% protect your assets, it’ll foil a less persistent cybercriminal.
Phishing attacks on bridge companies in conjunction with software hacks are also common. In this scenario, there’s unfortunately not much you can control. What you can control is how quickly and completely you respond to the cybercrime event. Remove the bridge software from your devices, transfer all your assets to a hardware wallet, and await further instructions from the bridge company on how to proceed.
Decentralized finance, or DeFi, is now one of the riskiest aspects of cryptocurrency. DeFi is a system without governing bodies. Some crypto traders like the anonymity and autonomy of being able to make transactions without a bank or institution tracking their assets. The drawback is that the code used in smart contracts isn’t bulletproof and has been at the center of several costly cybercrimes. Smart contracts are agreed upon by crypto buyers and sellers, and they contain code that programs crypto to perform certain financial transactions.
Three multi-million-dollar heists – Wormhole, Beanstalk Farms and Ronin bridge – occurred in quick succession, and smart contracts were at the center of each.4 In the case of Wormhole, a cybercriminal minted 120,000 in one currency and then traded them for Ethereum without putting up the necessary collateral. In the end, the hacker cashed out with $320 million. Beanstalk Farms lost $182 million when a hacker discovered a loophole in the stablecoin’s flash loan smart contract. Axie Infinity’s Ronin bridge was hit for $625 million when a hacker took control over and signed five of the nine validator nodes through a smart contract hole.4
To be safe, conduct all crypto transactions on well-known and trustworthy software, applications, bridges, and wallets that are backed by a governing body. What you lose in anonymity you gain in security by way of regulated protocols. Hackers are targeting smart contracts because they do not have to depend on large-scale phishing schemes to get the information they need. Instead, they can infiltrate the code themselves and steal assets from the smartest and most careful crypto users. Because there’s almost no way you can predict the next smart contract hack, the best path forward is to always remain on your toes and be ready to react should one occur.
Don’t let these costly hacks be what stops you from exploring crypto! Crypto is great as a side hustle if you’re committed to security and are strategic in your investments. Make sure you follow the best practices outlined and arm all your devices (mobile included!) with top-notch security, such as antivirus software, a VPN, and a password manager, all of which are included in McAfee +.
Privacy, excellent security habits, and an eagle eye can help you enjoy the most out of cryptocurrency and sidestep its costly pitfalls. Now, go forth confidently and prosper in the crypto realm!
