Native Shared Object (.so) Decompilation & Decryption

Native Binaries Cryptographic Decompilation

SEC_LEVEL CRITICAL

STABILITY_MED 99.10%

ANALYSIS_TIME 2.4s

Low-level reverse engineering and decryption of compiled C/C++ shared dynamic libraries (.so / .dylib). Targets advanced obfuscation, Obfuscator-LLVM control flow flattening (OLLVM), custom cryptographic constants, and dynamic symbol scrambling through static dataflow tracking and Unicorn CPU emulation.
