Stealing Reasoning Traces from Proprietary LLM APIs

3x SOURCES 🌐 📅 2026-08-10

⚡ Score: 8.6

+++ Turns out LLM providers' clever scheme to hide chain-of-thought reasoning by encrypting and shuttling it between client and server has a fundamental flaw: the encrypted blocks work across sessions, making them reusable tokens ripe for extraction. +++

💬 HackerNews Buzz: 159 comments 👍 LOWKEY SLAPS

🎯 Encryption vulnerability exploitation • Provider distrust & opacity • Safeguard inadequacy

💬 "The hiding of this data only brings distrust to their frontier models" • "We take a trace produced by a frontier model, replay it into a weaker sibling, jailbreak the weaker model"

"Leading large language model providers now conceal their models' step-by-step reasoning, or chain-of-thought, to protect intellectual property and limit information leakage. Rather than storing these traces server-side, providers return them to the client as blocks of encrypted text, which the clien..."
