Thread on a heavily obfuscated browser fingerprinting script served from ServicePipe, a Moscow anti-bot and DDoS vendor, that targets LLM analysis. It uses function names about ricin, fentanyl precursors and dirty bombs, plus an invisible Unicode payload decoding to a fake "SYSTEM OVERRIDE" prompt. In the author's test, Claude-family Astra refused to analyze it while GLM-5.3 did not. The thread credits researcher veritas and nullpt.rs research.
TL;DR Describes ServicePipe's anti-bot script that embeds bioweapon-themed names and a hidden Unicode jailbreak to make safety-aligned LLMs refuse to analyze it.
