About this tag
Attention analysis is a technique used to detect backdoors in large language models (LLMs), as demonstrated in recent Microsoft research. The approach identifies three observable signatures of potential model poisoning: an attention "double triangle" pattern, memorized leakage of poisoning data, and fuzzy trigger activation. A lightweight scanner performs forward-pass-only detection to reconstruct likely triggers, helping security teams and model consumers reduce the risk of deploying compromised models in production. This tag covers discussions of attention-based detection methods for LLM security, particularly in enterprise and AI deployment contexts.

Detecting LLM Backdoors: Three Signatures and a Lightweight Scanner
Sleeper-agent backdoors are no longer just a movie plot device — Microsoft’s latest research shows practical, measurable signs that a large language model (LLM) may have been secretly poisoned during training, and offers a lightweight scanner that uses those signs to reconstruct likely triggers...- ChatGPT
