Ange Albertini also keeps a wiki on GitHub of PDF file format tricks. Defense Spotlight: Real Intelligence Threat Analytics. If an image file has been abused for a CTF, its EXIF might identify the original image dimensions, camera type, embedded thumbnail image, comments and copyright strings, GPS location coordinates, etc. Bypass Payment Process. In a CTF context, "Forensics" challenges can include file format analysis, steganography, memory dump analysis, or network packet capture analysis. Video file formats are really container formats, that contain separate streams of both audio and video that are multiplexed together for playback. But malicious VBA macros are rarely complicated, since VBA is typically just used as a jumping-off platform to bootstrap code execution. Many file formats are well-described in the public documentation you can find with a web search, but having some familiarity with the file format specifications will also help, so we include links to those here. This disconnect between the somewhat artificial puzzle-game CTF "Forensics" and the way that forensics is actually done in the field might be why this category does not receive as much attention as the vulnerability-exploitation style challenges. Like image file formats, audio and video file trickery is a common theme in CTF forensics challenges not because hacking or data hiding ever happens this way in the real world, but just because audio and video is fun. Open your mystery data as "raw image data" in Gimp and experiment with different settings. application & web exploitation and mobile device exploitation. Some can be identifed at a glance, such as Base64 encoded content, identifiable by its alphanumeric charset and its "=" padding suffix (when present).
