PinCTF

Effectively uses instruction count variations to brute-force flags in CTF binaries, as shown in examples like wyvern and crypt4 where correct characters cause detectable deviations.

Supports analyzing binaries that validate input backwards with the -rev flag, bypassing fuzzing countermeasures demonstrated in the ELF-NoSoftwareBreakpoints example.

Includes threading support (-t flag) to parallelize character testing, reducing brute-forcing time in multi-core setups, as evidenced by the crypt4 example with a 4-thread run.

Identifies correct flag length by analyzing instruction count differences across input lengths, a critical first step shown in the wyvern example where length 28 was pinpointed.
