CARBANAK Week Part Four: The CARBANAK Desktop Video Player

This FireEye blog post analyzes CARBANAK's custom desktop video capture and playback components: the C2 server code that serializes video streams into .frm files, the desktop video player that parses and plays those files, and sample captured footage showing an operator preparing post-exploitation actions. The report links the capability to FIN7 activity, describes two file-format variants (compressed and raw), highlights relevant artifacts (file headers, extension, timestamps, IP encoding), and discusses how attackers used recorded desktop videos to understand bank workflows and facilitate fraudulent transactions.
