grap

grap: define and match graph patterns within binaries:
grap takes patterns and binary files, uses a Casptone-based disassembler to obtain the control flow graphs from the binaries, then matches the patterns against them. Patterns are user-defined graphs with instruction conditions (“opcode is xor and arg1 is eax”) and repetition conditions (3 identical instructions, basic blocks…). grap is both available as a standalone tool with a disassembler and as an IDA plugin which takes advantage of the disassembly done by IDA and the reverser.
