Microsoft has sounded the alarm on a pervasive piece of malware that has already infected hundreds of thousands of PCs. A few weeks ago, we reported on the Clop gang's involvement in the large-scale data leaks at Hertz.

Earlier this month, a coordinated disruption action targeting the Lumma malware-as-a-service (MaaS) information stealer operation seized thousands of domains, part of its infrastructure backbone worldwide.

The Lumma infostealer has become a popular way for hackers to steal sensitive data like banking information and cryptocurrency wallets.

The modular malware is tailor-made for ransomware as it features dedicated plugins for theft, encryption, and persistence.

Software drivers for China-based Procolored's printers were serving malware to users for six months, according to a security researcher. It's now removed the software from its website.

The widely viewed AI-generated videos, which offer free upgrades to premium services from Spotify and Microsoft, are being used to install malicious code that can spy on users’ PCs.

The reality is, every computer should have an antivirus program – even Mac owners should consider adding third-party antivirus software at this point. However, it's particularly important for Windows 11 users because they're even more likely to be targeted by malware, ransomware, phishing, spyware or other cyberattacks.
