Secure Ransomware Development 101 ~ understanding compiler optimizations

This educational article examines compiler optimizations, specifically Dead Store Elimination (DSE) and Dead Code Elimination (DCE) under the -O3 flag. Using C code examples and disassembly, it demonstrates how compilers remove unused memory writes (like memset) and unreachable computations, which has direct implications for security-sensitive code such as memory-wiping routines.
