CST VerdictBased on our analysis of available product data, here is our conclusion:
Burp Suite users who need to hunt for application-specific signatures and malware patterns in intercepted traffic should reach for Yara-Scanner; it's the only free extension that lets you write and deploy custom Yara rules directly against your proxy traffic without leaving the tool. The 48 GitHub stars and active Python codebase signal a small but committed user base. Skip this if your team lacks Yara rule expertise or if you need vendor-maintained detection logic; you'll spend more time writing rules than scanning.
YAYA - Yet Another Yara Automaton
Threat hunters and incident responders who need to operationalize Yara rules without writing automation scripts should use YAYA; it pulls open-source rule sets, deduplicates them, and runs scans automatically, saving weeks of manual curation work that most teams skip entirely. The GitHub community has validated the approach with 302 stars and active maintenance, which matters because stale Yara tooling becomes useless fast. This is free software, so there's no vendor lock-in, but also no support contract if your scan performance tanks on a 10TB dataset or your rules conflict in production.
