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!

Ransomware is one of the most dangerous threats organizations face today, so it’s no wonder that Cisco Talos Incident Response named it the top threat of the year in 2021. These attacks continue to grow and become more advanced, with ransomware attacks growing by 13% over 2021 and a whopping 79% over 2020 so far this year (see Figure 1 below).1 Stopping ransomware attacks isn’t easy either, as adversaries continue to change their techniques and attacks become increasingly sophisticated.
Fortunately, Cisco Secure Endpoint defends your organization from ransomware by delivering security outcomes that enable you to radically simplify your security, maximize your security operations, and achieve peace of mind. Let’s dive deeper into each of these areas to better understand how Secure Endpoint can help your organization defend against ransomware attacks.
Cybersecurity has become increasingly complex due to the numerous security solutions deployed by organizations today. These disparate point-products increase complexity while creating security gaps because they require additional management overhead and typically don’t communicate with each other. This increases the burden on security operations teams since they must spend time managing these different solutions and filling in the gaps between tools rather than using their time to investigate and respond to threats
Cisco takes a very different approach to cybersecurity by looking at ransomware endpoint protection holistically, as part of an integrated security solution. For instance, Secure Endpoint includes built-in extended detection and response (XDR) capabilities from the Cisco SecureX platform that centralizes visibility in a single console, creates high-fidelity detections by correlating threats, and coordinates threat response across your entire security environment. In addition, Secure Endpoint unifies your security stack, simplifies management, and reduces agent fatigue because we’ve consolidated endpoint protection, cloud security, and remote access agents into a single agent.
Learn more about how Secure Endpoint helps you simplify your security while defending your organization from ransomware attacks by watching this video:
One of the common themes we’ve heard from our customers is that their security operations teams are frequently overstretched. The ongoing cybersecurity skills shortage means that security teams have to do more with less and a vast number of security tools to manage along with inefficient security operations processes, often leading to burned-out security teams.
Cisco addresses these challenges by allowing you to get the most out of your security operations. For example, you can accelerate investigation and incident response with valuable vulnerability context since we’ve integrated risk-based vulnerability management from Kenna Security into Secure Endpoint. Moreover, Secure Endpoint includes advanced endpoint detection and response (EDR) capabilities via Orbital Advanced Search and built-in XDR from SecureX that enable you to rapidly detect, respond to, and contain ransomware attacks. Lastly, you can get the security expertise you need with proactive threat hunting from SecureX Threat Hunting, which uses an analyst-centric process to quickly spot hidden ransomware.
Check out how Secure Endpoint helps you maximize your security operations while defending your organization from ransomware attacks by watching this video:
Keeping up with the latest ransomware attacks can seem like an impossible challenge due to Ransomware-as-a-service (RaaS) kits which make it simple and lucrative to target organizations with ransomware and the evolving threat landscape, where attackers are continuously changing their methods to evade detection.
Cisco helps you stay ahead of the newest ransomware attacks and gives you the peace of mind you deserve by taking a comprehensive approach to ransomware endpoint protection. This means ensuring that you never have to go it alone with always-on security operations from Cisco Secure Endpoint Pro, a managed service that uses a team of Cisco security experts to perform the heavy lifting of securing your endpoints. It also includes offering advanced EDR and integrated XDR capabilities such as Orbital and SecureX to speed detection and response, simplify investigations, and quickly contain ransomware attacks before it’s too late. Finally, Secure Endpoint prevents initial ransomware infections with multifaceted prevention techniques such as machine learning, exploit prevention, and behavioral protection as well as actionable threat intelligence from the Cisco Talos research team.

Our all-new ransomware coverage is now available, ready to help just in case—all backed by expert advice to help you find the quickest and best possible path to recovery.
Ransomware coverage from McAfee can reimburse you up to $25,000 for losses resulting from a ransomware threat, including financial losses and ransom fees. You’ll find this ransomware coverage included with our McAfee+ Ultimate plan.
As well as eligibility for ransomware reimbursement, our team of experts can help you:
However, it’s important to realize that ransomware is unlike any other attack. When ransomware locks someone out of their device or encrypts their data and files so they can’t use them, a demand is usually made for money. Sometimes, paying the ransom results in the device being made accessible again or the files being decrypted. Yet like any ransom case, this result is not always guaranteed. There are plenty of cases where people pay the ransom but never get their data or access to their devices back.
Again, our coverage includes guidance from our expert advisers to help walk you through your options should the worst happen to you. You won’t be in it alone—particularly as you look to recover from what can be a complicated attack.
As the name implies, ransomware is a type of malware that holds your device or information for ransom. It may lock your computer or smartphone entirely or it may you out of your files by encrypting them so that you can’t access them. Whether it’s a hacker or a cybercrime organization behind the attack, the bad actor involved holds the key to unlock those files—and promises to do so. For a price. And as mentioned above, sometimes that doesn’t happen, even if you pay.
Ransomware can infect your devices several different ways:
Ransomware has seen quite the evolution over the years. Its origins date back to the late 1980s, where malware-loaded floppy disks were sent to users who installed them under false pretenses. There the malware would lie in wait until the user rebooted their computer for the 90th time and presented with a digital ransom note.
From there, ransomware attacks on individuals became more sophisticated, and more lucrative, with the advent of the internet and the millions of everyday users who flocked to it. Using phishing emails, malware downloads from phony sites, and compromised software and networks, hackers rapidly expanded their ransomware reach.
However, yet more lucrative for hackers and organized cybercriminals were public and private organizations. Shifting their attacks to so-called “big game” targets, hackers and organized cybercriminals have used ransomware to extort money from hospitals, city governments, financial institutions, and key energy infrastructure companies, to name just a few. Seeing further opportunity, ransomware attackers then began targeting smaller and mid-sized businesses as well. While the ransom demands account for lower amounts, these organizations often lack dedicated cybersecurity teams and the protections that come along with them, making these organizations easier to victimize.
Meanwhile, the body of malicious code and attack packages used to launch ransomware attacks has only grown. As a result, small-time hackers and hacking groups can find the tools they need to conduct an attack for sale or for lease as a service (Ransomware as a Service, or RaaS). In effect, these bad actors can simply access a dark web marketplace and figuratively pull a ready-to-deploy attack off the shelf.
As a result, ransomware remains a concern for individuals, even as businesses and governmental bodies of all sizes deal with its threat.
What makes ransomware so damaging is just how much effort it can take to undo. Setting aside the sophisticated attacks on businesses and governments for a moment, even those “off-the-shelf” attacks that some hackers will launch against individuals go beyond the average user’s ability to undo. For example, there are some known attacks with known methods of decrypting the data, however, that requires knowing specifically which attack was used. Attempting to undo the encryption with the wrong solution can potentially encrypt that data even more.
So without question, the best defense against ransomware is prevention. Comprehensive online protection software gives you the tools you need to help avoid becoming a ransomware victim. A few include:
Moreover, you can protect yourself further by backing up your files and data. A cloud storage solution,121cwdv 1765ujb n4yh that’s secured with a strong and unique password, offers one path. Likewise, you can back up your files on an external disk or drive, making sure to keep it disconnected from your network and stored in a safe place.
Also as mentioned in the bullets above, keep your operating system and apps current with the latest updates. Beyond making improvements in your operating system and apps, updates often also address security issues that hackers often use to compromise devices and apps.
Lastly, stay alert. Keep an eye out for sketchy links, attachments, websites, and messages. Bad actors will pull all kinds of phishing tricks to lure you their way, places where they try to compromise you, your devices, and data.
Taken together, the combination of online protection software and a few preventative steps can greatly reduce the chance that you’ll fall victim to ransomware. From there, you also have the assurance of our ransomware coverage, ready to get on the path to recovery, just in case.

The social network TikTok is chockfull of interesting, fun, laugh-out-loud videos shared by creators worldwide. Kids, as well as parents, can easily spend hours glued to the platform. But as with most popular platforms, the fun can eventually turn dark, even deadly, when viral challenges make their rounds.
The latest viral challenge, the “blackout challenge,” first became popular online in 2008 and made its unfortunate comeback in 2021. Before this second round, the CDC attributed nearly 80 deaths to the dangerous online game. In the past month, authorities are attributing the tragic, high-profile deaths of Archie Battersbee, 12, and Leon Brown, 14 to the challenge.
The blackout challenge is a choking game that involves intentionally trying to choke oneself or another to obtain a brief euphoric state or “high.” Death or serious injury can result if strangulation is prolonged. Those doing the challenge do it privately or broadcast their attempt to friends or followers. The CDC also found that most deaths occurred when a child engaged in the choking game alone and that most parents were unaware of the game before their child’s death.
It’s easy to look at a challenge like this and dismiss it thinking your child would never be involved in such a dangerous game. However, in a recent post from HealthyChildren.org on why kids participate in online dares, pediatricians point to the reality that the teen brain is still developing. The part of the brain that processes rational thought, the prefrontal cortex, is not fully developed until a person’s mid-20s. This physiological reality means teens are naturally impulsive and can do things without stopping to consider the consequences.
Another lure that entices teens is that social media’s fast-moving, impulsive environment rewards outrageous behavior—the more outrageous the content, the bigger the bragging rights. The fear of losing out (FOMO is natural for teens.
According to the CDC, signs that a child may be engaging in the blackout challenge include:
Viral challenges will continue to emerge and shock us. There’s no way to anticipate them or control them. However, staying informed about dangerous online trends and keeping the lines of communication with your child open and honest is a big step toward equipping them to live a safe, balanced digital life.

Safety has a feeling all its own, and that’s what’s at the heart of McAfee+.
We created McAfee+ so people can not only be safe but feel safe online, particularly in a time when there’s so much concern about identity theft and invasion of our online privacy.
And those concerns have merit. Last year, reported cases of identity theft and fraud in the U.S. shot up to 5.7 million, to the tune of $5.8 billion in losses, a 70% increase over the year prior. Meanwhile, online data brokers continue to buy and sell highly detailed personal profiles with the data cobbled together from websites, apps, smartphones, connected appliances, and more, all as part of a global data-gathering economy estimated at well over $200 billion a year.
Yet despite growing awareness of the ways personal information is collected, bought, sold, and even stolen, it remains a somewhat invisible problem. You simply don’t see it as it happens, let alone know who’s collecting what information about you and toward what ends—whether legal, illegal, or somewhere in between. A recent study we conducted showed that 74% of consumers are concerned about keeping their personal information private online. Yet, most of us have found out the hard way (when we search for our name on the internet) that there is a lot of information about us that has been made public. It is our belief that every individual should have the right to be private, yet we know too many individuals don’t know where to begin. It is this very worry that made us focus our new product line on empowering our users to take charge of their privacy and identity online.
McAfee+ gives you that control.
Now available in the U.S., McAfee+ provides all-in-one online protection for your identity, privacy, and security. With McAfee+, you’ll feel safer online because you’ll have the tools, guidance and support to take the steps to be safer online. Here’s how:
You can see the entire range of features that cover your identity, privacy, and security with a visit to our McAfee+ page.
McAfee+ Ultimate offers our most thorough protection, with which you can lock your credit with a click or put a comprehensive security freeze in place, both to thwart potential identity theft. You can keep tabs on your credit with daily credit monitoring and get an alert when there’s credit activity to spot any irregularities quickly.
You’ll also feel like someone has your back. Even with the most thorough measures in place, identity theft and ransomware attacks can still strike, which can throw your personal and financial life into a tailspin. What do you do? Where do you start? Here, we have you covered. We offer two kinds of coverage that can help you recover your time, money, and good name:
Starting today, customers in the U.S. can purchase McAfee+ online at McAfee.com in Premium, Advanced, and Ultimate plans, in addition to individual and family subscriptions. McAfee+ will also be available online in the U.K., Canada, and Australia in the coming weeks with additional regions coming in the months ahead (features may vary by region).
We are very excited about bringing these new protections to you and we hope you will be too.
