Overview
XOR is a reversible byte-wise operation often used to hide strings or data inside binaries.
XOR is common in reverse engineering because it is easy to implement, fast, and reversible when the key or operation pattern is understood. Malware, crackmes, and protected applications often use it to hide readable strings from basic static analysis.
In this lab, you practice recognizing XOR-style transformations, tracing how data is decoded at runtime or in code, and separating simple obfuscation from real cryptographic protection.
