@richeeta
The interesting bugs live between the boxes.
I’m Richard Hyunho Im, co-founder and security researcher at Route Zero Security. My work focuses on systems that interpret human language or move information across trust boundaries—especially Apple platforms and AI-enabled products.
I build reproducible proofs of concept, trace the actual boundary failure, and communicate it in a form product and security teams can act on. I also created AI Auditor and 0xGUIDScanner.
