kryptokat is the research handle of Charlotte, an independent security researcher working at the intersection of adversarial machine learning, steganography, and offensive security. The focus is purple-team: understanding attacks well enough to help defenders build systems that survive them.
Most work here sits in one of three places — multimodal AI attack surfaces, classical steganography ported forward into the LLM era, and the practical question of how you actually assess AI-enabled applications in the wild.
