Reverse Engineering

REV your engines

The UNB Cyber team has built a mysterious executable that claims to “verify” a flag — but the real flag is nowhere in sight. The binary contains a strange encoded blob, a few cryptic math functions, and some suspicious bit-twiddling. Your mission? Reverse the algorithm, understand how it rebuilds the flag, and extract the correct value.
