  • Engineer — Learn: Novel black-box attack class against LLM inference systems using shared KV caches for reasoning trace reuse — engineers building or deploying such systems should audit whether their architecture exposes shared cache state across users or sessions, and treat this as a design constraint before enabling reasoning-cache reuse features.
