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.
Detection engineers and SOC analysts who need to standardize threat signatures across multiple SIEM platforms should start with Sigma; it's the only open format with 10,000+ community-written rules that port directly between tools without vendor lock-in. The format has adoption across Splunk, Elastic, Microsoft Sentinel, and a dozen other platforms, meaning your detection work compounds rather than evaporates when you swap vendors. Skip Sigma if your team lacks the expertise to write or maintain detection logic; it's a framework for people who already know how to hunt, not a turnkey rules engine that ships with pre-tuned detections.
