CST VerdictBased on our analysis of available product data, here is our conclusion:
Mobile security teams testing native Android libraries and system components need Android port of Radamsa because it's one of the few fuzzers that generates valid mutation sequences across ARM and x86 ABIs without requiring app recompilation. The tool's 68 GitHub stars and zero-dependency native compilation via Android NDK make it fast to integrate into CI/CD pipelines for pre-release fuzzing of C/C++ code. Skip this if you're fuzzing Kotlin/Java app logic or need guided feedback-driven fuzzing; Radamsa is mutation-based and dumb, which is exactly why it finds edge cases that smarter fuzzers miss.
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.
