Red team operators and offensive security researchers validating endpoint detection gaps will find InvalidSign useful for its straightforward approach to signature evasion through hash manipulation of legitimately signed binaries. The tool is free and open-source, lowering barriers to testing your own defensive posture. This is not a replacement for behavioral detection tuning or a tool for teams whose EDR already flags execution context anomalies; InvalidSign assumes signature-based controls remain your primary detection layer.
