HookSteg: A Truly Lossless Steganography Based on Process Hooking for Lossy Network Channels

HookSteg is a new steganography method (hiding secret data inside images) that achieves zero-error transmission of hidden information through lossy channels like social media platforms. It uses process hooking (intercepting system function calls to modify behavior) and dynamic taint tracking (monitoring how data is altered) to detect and bypass compression and scaling attacks that normally corrupt hidden data, improving extraction accuracy by 36.63% compared to existing methods.
