Mitigation checklist
- To mitigate this issue, ensure that YARA only loads compiled rule files (`.yrc`) from trusted sources. Avoid processing or loading `.yrc` files from untrusted or unverified origins. If YARA is used in an automated fashion, implement strict input validation and source verification for all rule files.
