chernobog

chernobog is a Hex-Rays decompiler plugin for Hikari LLVM obfuscation. The reviewed notes for 6.5 use CoBRA to propose mixed Boolean-arithmetic candidates and Z3 to check the candidate and the emitted microcode or ctree. CHERNOBOG_MBA_BACKEND=legacy keeps the previous generator. A deep-deobfuscation action raises the per-function semantic budget from 1 second to 30 seconds. The plugin also covers opaque predicates, string decryption, and x86 flag and memory models.
