New Settra Ransomware Variant Deployed in Attacks on Retail and Manufacturingnew
Huntress details a new Settra ransomware variant deployed against retail and manufacturing victims since June, using MeshAgent RMM, recovery sabotage, and BYOVD techniques.
Huntress reported a new Settra ransomware variant, first observed in June, used in a July attack on a consumer services and retail organization and a September attack on a manufacturing firm. In the retail attack, MeshAgent RMM connected to attacker C2, the ransomware ran from C:\Perflogs, encrypted files with the .locked extension, and created a ransom note; the executable was named after the victim's domain in both incidents. Attackers cleared Windows Event Logs, disabled the Windows Recovery Environment, flushed DNS cache, used DiskPart to remove the recovery partition, and ran Cipher to overwrite free space. The September attack added BYOVD; prior research links Settra to double extortion, and initial access remains unconfirmed.
