360 Security Centre analysts have discovered a new version of Magniber ransomware targeting systems running Windows 11. On May 25, the volume of attacks using Magniber increased significantly, according to experts.
Ransomware is distributed through several online platforms, pirated software sites, fake pornographic sites, etc. When a user visits a fake site, the attackers try to force the victim to download a malicious file from their network drives.
According to the researchers, the ransomware has not changed much, but now it can infect multiple versions of Windows.

Magniber uses the RSA and AES encryption algorithms to encrypt victim files. The RSA algorithm is 2048 bits long, which makes Magniber hard to crack. After encryption, the file suffix becomes random, and a separate payment page opens for each victim.
According to security researchers, there is no secure decryptor for this ransomware. In addition, experts do not yet know about the weak points of the malware that can reverse the infection.
Magniber targets ordinary users, not companies, so experts recommend that users remain vigilant, do not download pirated software, and use only official sites.
Recall that this is the second case in two months when Magniber attacks Windows users. In April, attackers used fake Windows 10 updates to spread malware.
