steghide

Classic hidden-payload tooling for media files that look innocent until they absolutely do not.

When to use steghide

Use steghide when you need to:

• check supported cover files for hidden payloads
• extract content with or without a candidate passphrase
• embed a test payload into a supported media file in a lab workflow

Quick Start

# Inspect carrier info
steghide info image.jpg
 
# Extract hidden payload
steghide extract -sf image.jpg
 
# Embed data into a cover file
steghide embed -cf cover.jpg -ef secret.txt

Practical Notes

• info is a good first move before guessing wildly.
• Pair with stegseek when the artifact is likely a steghide file protected by a weak passphrase.
• Keep original carrier hashes if the artifact matters for evidence or writeups.

Caveats

• Format support is narrower than generic stego folklore suggests.
• Extraction success may still depend on the correct passphrase.
• Unsupported or visually suspicious files may belong to a different stego family entirely.
