Weekly Intelligence Report - 09 January 2026 - CYFIRMA

Ransomware targeting Windows that encrypts files (RSA+AES described), appends the .ripper12 extension, changes desktop wallpaper, drops a ransom note (READ_NOTE.html), and claims data exfiltration for double-extortion leverage. It also attempts to inhibit recovery by deleting Volume Shadow Copies (vssadmin/wmic).
