ZenithSouu on 2026-04-04 16:08: Great Tier 5 crackme! The checking algorithm is well-thought-out, and the anti-debug stub adds a nice little challenge to get the brain moving. The C++ flow is solid, though the conditional jumps and RIP-relative offsets didn't stand a chance against some deep static analysis.

gxentrys on 2026-04-18 01:42: // Key must be EXACTLY 10 characters int v7 = 0; for (int i = 0; i < 10; i++) { v7 = 11 * i + ((key[i] << (i % 3)) ^ v7); } // WIN condition: v7 == 1337 so every key that is v7 == 1337 will grant you access and it must be 10 characters
