ultrazvukoff on 2025-10-28 19:30: No offense, but this crackme is definitely not a 4.0 in difficulty. First, all strings are accessible, and second, by simply inverting a single conditional jump at 0000000140001D93 | 0F84 6D010000 | je crack-me.140001F06, you can immediately trigger the success message. The anti-debugging protection is easily bypassed by enabling the ScyllaHide plugin. Any 32-character password will be accepted as valid.

jmp_sh0t on 2025-11-05 15:44: Hey, thanks for writing challenge. I do think it's broken though, it accepts any 32-byte input.

Luainterpreter on 2025-11-18 15:08: very easy, should be a 1, debug check can be patched in second, change the JMP from 0f 85 to 0f 85 and done, prevents it from ever going to fail or "fake success" ( used solely IDA)
