# Schneier on Security

**[Schneier on Security](https://daily.dev/sources/schneier)** · 1 min read · 0 upvotes · 0 comments

## Summary

A malware developer has embedded policy-triggering text about nuclear and biological weapons inside JavaScript comment blocks in spyware. The technique targets AI-powered analysis pipelines: by placing forbidden content at the start of a file, it can cause LLM-based scanners or analyst copilots to refuse analysis, get confused, or misclassify the file before reaching the actual malicious code. The trick exploits naive LLM-first triage systems that feed raw file content to a language model without isolating it as untrusted. Traditional static analysis tools like YARA rules, entropy checks, and AST parsing remain unaffected.
