CST VerdictBased on our analysis of available product data, here is our conclusion:
Forensics teams and incident responders hunting PHP shells in compromised web applications should use lw-yara for its laser focus on webserver malware detection; the 107 GitHub stars and active maintenance show this ruleset actually gets used in post-breach investigations where generic YARA rules fall short. The free pricing means you can bake it into your DFIR playbooks without budget friction. Skip this if you need detection across the full application stack or run primarily on non-PHP infrastructure; lw-yara does one thing and won't help you find .NET backdoors or kernel rootkits.
OCaml developers who need malware detection baked directly into their applications should consider ocaml-yara; it's the only straightforward way to call YARA rules from OCaml without subprocess overhead or language bindings friction. The tool uses Ctypes for direct C interop, meaning you get YARA's pattern matching engine without wrapping complexity. Skip this if your team isn't already committed to OCaml or if you need a maintained, production-hardened library; with 12 GitHub stars and no commercial backing, you're accepting some risk on future updates and edge case handling.
