To find plain-text clues hidden in the binary code.
If this is a forensic challenge, the write-up would focus on:
The first step in any deep dive is establishing what the file actually is. While it has a video filename, the .rar extension indicates it's a compressed archive. VID_20220520_001343_743.rar
Often in CTFs, "video" files contain hidden data. A write-up would detail using tools like StegSolve or binwalk to find hidden offsets or strings (flags) embedded in the frames or audio tracks.
Analysts look for nested files. Is there just one VID file inside, or are there hidden scripts, executables, or document files? 2. Forensic Analysis (The "Deep" Dive) To find plain-text clues hidden in the binary code
The filename suggests the media was captured on May 20, 2022, at 12:13:43 AM .
Does running the file (in a sandbox) attempt to reach out to a Command & Control (C2) server? Often in CTFs, "video" files contain hidden data
If a video file is inside, analysts use tools like ExifTool to find the GPS coordinates of the recording, the device model, and software versions.
