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.
Forensics analysts and incident responders who frequently encounter obfuscated malware samples will find xortool.py invaluable for quickly breaking single-byte XOR encryption without manual key guessing. The tool's frequency analysis engine accurately identifies key lengths in seconds and handles the repetitive cryptanalysis work that otherwise consumes hours of manual effort. Skip this if you're looking for a GUI or multi-cipher support; xortool.py is CLI-only and handles XOR specifically, which is precisely why it's faster than generic cryptanalysis frameworks for this narrow use case.
