Performing Steganography Detection

When to Use

• When suspecting covert data hiding in images, audio, or video files
• During investigations involving suspected data exfiltration via media files
• For analyzing files in espionage or insider threat investigations
• When standard file analysis reveals anomalies in media file properties
• For detecting communication channels using steganographic techniques

Prerequisites

• StegDetect, zsteg, stegsolve, binwalk for analysis
• steghide, OpenStego for extraction attempts
• ExifTool for metadata analysis
• Python with Pillow, numpy for custom analysis
• Understanding of common steganographic techniques (LSB, DCT, spread spectrum)
• Sample files for comparison and statistical analysis
