CST VerdictBased on our analysis of available product data, here is our conclusion:
GCTI Open Source Detection Signatures
Security teams deploying open-source tooling or running detection infrastructure without commercial licensing will find real value in GCTI Open Source Detection Signatures; the 553 GitHub stars and active contribution model mean you're working with signatures that security practitioners are actually using and refining in production. The free pricing eliminates the budget friction that blocks detection rule adoption at smaller organizations and budget-constrained teams. Skip this if you need vendor-backed SLA support, managed rule updates, or integration with commercial SOAR platforms; GCTI requires you to own the operational work of testing, tuning, and maintaining signatures as malware evolves.
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.
