This article explores the use of basic steganography techniques to hide Command and Control (C2) commands within SVG files for cyber operations. The approach involves encoding command data into SVG element properties, making it covert and difficult to detect. #Steganography #C2Commands
Keypoints
- Steganography is used to hide messages within SVG files by encoding data in element properties.
- SVG files are ideal for this method due to their XML format, scalability, and frequent web usage.
- Geometric properties such as cx, cy, and r are utilized to store ASCII character codes of commands.
- A proof-of-concept SVG generator encodes C2 commands across multiple hidden circle elements.
- Alternative encoding methods like Least Significant Bit manipulation can also embed data without affecting image quality.
