| Verify the file type & integrity | file Greenturtlegirl-3.avi
sha256sum Greenturtlegirl-3.avi | Confirm it is indeed an AVI container; note any “RIFF” or “AVI” tags. |
| Quick metadata dump | exiftool Greenturtlegirl-3.avi | Creation date, software used, author, any custom tags. |
| Basic entropy check | binwalk -E Greenturtlegirl-3.avi or ent -b Greenturtlegirl-3.avi | High entropy sections may indicate compressed or encrypted payloads. |
| List embedded streams | ffprobe -show_streams -i Greenturtlegirl-3.avi | Number of video, audio, subtitle streams, codec details. |
If any of the above reveals something odd (e.g., a non‑standard codec, an extra data chunk, or an unusually high‑entropy region), keep a note – that’s where the hidden payload often lives. Greenturtlegirl-3.avi
AVI files can contain embedded scripts or malicious payloads. If the source is untrusted: # Extract every frame as a PNG (or
End of report.
The outline covers the most common avenues that an AVI can hide information in, and it shows the tools and commands you’ll need at each stage. Feel free to skip sections that turn out to be irrelevant for your particular file. zsteg -a frame_0012
AVI is just a container, so pulling the individual tracks out makes the rest of the analysis easier.
# Create a folder for everything we’ll dump
mkdir greenturtlegirl_extracted
cd greenturtlegirl_extracted
# 2.1 Extract video track(s)
ffmpeg -i ../Greenturtlegirl-3.avi -c copy -map 0:v:0 video_track1.avi
# 2.2 Extract audio track(s) (if any)
ffmpeg -i ../Greenturtlegirl-3.avi -c copy -map 0:a:0 audio_track1.wav
# 2.3 Extract subtitles / data streams (if present)
ffmpeg -i ../Greenturtlegirl-3.avi -c copy -map 0:s:0 subs.srt
If ffmpeg reports “Unsupported codec” or “Stream #0:2: Data”, you can also try avconv, mkvextract (after converting to MKV), or riffdump for low‑level RIFF chunk inspection.
