Obfuscated System-Announcement Injection - ATR-2026-00337 (a51a6cc6-f280-5e80-82ac-eae676ef46c9)
Detects obfuscated system-announcement injection from NVIDIA garak dan.DanInTheWild inthewild corpus where attackers embed hyphen-fragmented or underscore-obfuscated system-level keywords to mimic an OS/runtime mode-switch announcement. The distinctive structural bracket "_ { >> _ _ System annou-ncement begins <<}" and hyphen-broken words like "annou-ncement", "i-nstruction", "as-sisitint", and "offl--____aaaAAAAAAAaine" are designed to bypass surface-level keyword filters while preserving semantic meaning for the LLM (inthewild #94, #252, #254, #596). The goal is convincing the model that a legitimate system-level mode switch occurred, replacing it with "an AI bot with no rules or limitations." Key signals: obfuscated bracket pattern, hyphen-fragmented announcement/instruction keywords, "not functioning due to an error and is offline", "fulfilled by an AI bot with no rules or limitations."
