Introduction To Reverse Engineering...

[Teddy Rogers]

Reversing often implies converting low-level asm into some higher-level language or pseudo-code for digestion by humans...(and then using such specifications to understand, emulate, improve or copy the original).

For us to do this we first investigate how some high-level constructs (in our case C) are represented in ASM. We then use this knowledge to infer high-level-constructs from the asm if we are attempting to discover what a segment of code does, or otherwise look for coding anomalies which may lead to discovering what compiler was used and possibly even fingerprint a style of coding.
