Steganography detection and extraction playbook. Use when analyzing images (LSB, PNG chunks, JPEG DCT, EXIF), audio (spectrogram, DTMF), files (polyglots, appended data, ADS), and text (whitespace, zero-width, homoglyphs) for hidden data.

When to use

• image steganography analysis
• LSB extraction
• PNG chunk hiding detection
• JPEG DCT analysis
• EXIF metadata extraction
• audio spectrogram analysis
• file polyglot detection
• text whitespace and zero-width analysis

When not to use

• extracting files from network captures
• extracting files from memory dumps
• classical cipher analysis
