CST VerdictBased on our analysis of available product data, here is our conclusion:
OCaml developers embedding malware detection into custom security tools should use ocaml-yara for direct access to YARA's pattern-matching engine without language boundary overhead. The bindings are maintained by Elastic and free, which matters for teams building detection pipelines that need to call YARA thousands of times per second without spawning subprocess overhead. This is a poor fit for teams expecting a polished UI or integration with third-party threat feeds; ocaml-yara is a low-level library, not a scanning platform.
Penetration testers and forensic analysts who need to rapidly surface credential leakage and PII exfiltration in captured files will find Yara4Pentesters valuable because it's free, maintained on GitHub with 127 stars, and requires zero infrastructure investment to deploy across engagements. The rule set is purpose-built for the credential-hunting phase of post-compromise analysis, eliminating the setup overhead of building custom patterns from scratch. Skip this if you're looking for automated remediation or SOAR integration; Yara4Pentesters is a standalone pattern library that assumes you know how to write and execute YARA rules yourself.
