FileFix Campaign Uses Steganography and Multistage Payloads
🛡️ Acronis researchers have uncovered a rare FileFix campaign that hides a second-stage PowerShell script and encrypted executables inside JPG images using steganography. Attackers employ multilingual, heavily minified phishing pages that mimic a Meta support flow and trick victims into pasting a payload into file upload address bars. An obfuscated PowerShell one-liner downloads images from Bitbucket, extracts and decrypts components, and executes a Go-based loader that deploys StealC. Organizations should combine user training with process blocking and monitoring to mitigate this evolving threat.
