Even if the file appears “silent”, hidden data can be tucked in the audio channel.

# Convert to raw PCM for easier analysis
ffmpeg -i audio_track1.wav -f s16le -acodec pcm_s16le raw_audio.pcm
# Check for hidden spectrogram messages
sox raw_audio.pcm -n spectrogram -r -o spectrogram.png
# Use Audacity or Sonic Visualiser to zoom into the spectrum.

You can also run stegdetect on the WAV, or try StegExpose (it works on audio as well).

Replace the above with the actual output from your inspection.

AVI files (RIFF) can contain custom chunks that are ignored by standard players. Those chunks are a common place for CTF flag data.

# Dump all RIFF chunks (including unknown ones)
riffdump Greenturtlegirl-3.avi > riff_dump.txt

If you see something like:

Chunk: 'XXXX' size 0x00000100
Chunk: 'data' size 0x00000A00

You can extract the raw bytes:

# Grab the chunk named XXXX (replace with the actual 4‑letter ID)
dd if=Greenturtlegirl-3.avi bs=1 skip=$((offset)) count=$((size)) of=extra_chunk.bin

offset and size come from the riff_dump.txt output. After extraction, run a battery of checks:

# 4.1 Strings & printable data
strings -a extra_chunk.bin | head
# 4.2 Base64 / hex detection
base64 -d extra_chunk.bin 2>/dev/null | strings -a
xxd extra_chunk.bin | head

If you see something that looks like a flag (e.g., CTF...) you’re done. Otherwise keep probing.
