Gen has been closely monitoring cybersecurity trends, and their latest findings are alarming. Ransomware activity has surged, doubling in frequency from Q2 to Q3 of 2024. If you’ve heard about ransomware before, you’re probably familiar with its devastating effects. However, what’s happening right now is even more concerning. The rise of new strains and continued targeting of vulnerable systems means that the threat is only getting worse.
One ransomware variant, Magniber, has particularly caught Gen's attention. Its recent spike in activity is a stark reminder that we all need to stay vigilant when it comes to online security. Fortunately, there are proactive steps and tools you can use to protect yourself from these growing threats.
Let’s break down the key insights from their Q3 2024 Threat Report so you can stay informed and safeguard your digital life.
Quick Recap: What is Ransomware?
Ransomware is a type of malicious software designed to lock you out of your own files. Here’s how it usually works: You might click on a seemingly harmless link or download an innocent-looking file (often disguised as a software update). Once you do, your files—whether they’re family photos, important documents, or work files—are suddenly encrypted.
Then, you’ll receive a ransom note demanding payment in cryptocurrency (to make tracing harder). The payment is for the promise of unlocking your files, but there’s no guarantee you’ll actually get them back. Worse, paying the ransom can fuel further criminal activity.
The Magniber Ransomware Boom
Magniber, a well-known ransomware variant, has recently seen a shocking increase in activity. The attacks became especially fierce in August 2024, when the number of blocked URLs related to ransomware jumped from just a few hundred to nearly 8,000 per day. This spike is primarily attributed to a campaign known as AliGater, which spreads Magniber through malvertising. Essentially, users are tricked into downloading malicious software disguised as fake updates or useful tools.
For anyone unlucky enough to click on these malicious links, the result is the same: locked files, a ransom demand, and no guarantee of getting the data back. What makes Magniber particularly dangerous is that there is currently no decryption tool available for it. The best way to protect yourself is by using robust security software to block these attacks before they even have a chance to impact you.
Why Outdated Systems Are Ransomware’s Favorite Target
Magniber is particularly effective at targeting outdated systems, such as Windows 7. Despite Microsoft ending support for Windows 7 in 2020, approximately 4% of computers worldwide still run this outdated operating system. Since these systems no longer receive security patches, they are extremely vulnerable to ransomware attacks.
If you’re still using an older version of Windows, or any other unsupported software, it’s like leaving a door wide open for cybercriminals to exploit.

4 Essential Tips to Protect Against Ransomware
With ransomware on the rise, it’s more important than ever to take action and protect yourself. Here are four simple but crucial steps to help you stay ahead of the threat:
1. Update Your Software Regularly
Outdated software is a prime target for cybercriminals. Make sure your operating system and apps are always up to date to reduce your risk of falling victim to ransomware.
2. Back Up Your Files
Regularly back up your important files to an external drive or secure cloud service. That way, if ransomware strikes, you won’t lose everything. Having a clean copy of your files can save you a lot of time and frustration.
3. Think Before You Click
Malvertising campaigns often rely on users clicking on suspicious links or “update” prompts. If you’re ever unsure about a link or email, don’t click on it. When in doubt, err on the side of caution.
4. Use Strong Security Software
A reliable security suite, like Avast, can block ransomware before it has a chance to do damage. Avast’s real-time protection, ransomware shield, and behavior monitoring give you an extra layer of defense.
Good News for Mallox Victims: Free Decryption Tool Available
While Magniber continues to wreak havoc, there’s a silver lining for victims of another ransomware strain, Mallox. Gen researchers have developed a way to decrypt files affected by specific Mallox variants. If your files have been encrypted by Mallox, and the extensions end in .bitenc, .ma1x0, or .mallab, you’re in luck! You can use Avast’s free decryptor to recover your files.
You can find the decryption tool and instructions here on Avast’s official website.
Stay Aware, Stay Safe
Ransomware has doubled in a matter of months, and the threat is only growing. Now is the time to increase your cybersecurity defenses. By staying informed and taking proactive measures like updating your software, backing up your files, and using strong security tools like Avast, you can reduce the risk of becoming a victim.
The good news is that, while ransomware is a serious threat, with the right precautions, you don’t have to be its next target. Stay safe, stay smart, and don’t let ransomware win!
