# Chernobyl ### First impressions: - Location-independent (my god these relative jumps) - Copies itself around in memory - Tries to be cheeky, and overwrites the original memory - Sucks for it, my disassembler is so bad the instructions are wrong anyway - A top-down disassembly is not possible here. - Does long jumps by calculating large pc-relative offsets, pushing pc, and BR'ing them - Never used Ghidra before, but it really doesn't like this. It crashed so hard. - Decrypts_one_byte a lot -- and there's a blob of garbage in RAM. How fun. - Do I need to find an inverse of the encryption algorithm? #### TL;DR: Everybody knows it sucks
