Read MoreMany processors (especially RISC based) use instruction sets with fixed size (most commonly 4 bytes). Among examples are ARM, PPC, MIPS and a few others. This is also obvious in the disassembly when observing the instructions’ addresses – they increase by a fixed amount: However, occasionally you may come across larger instructions: What is this? Does A64 […]

Read MoreWhen decompiling code without high-level metadata (especially firmware), you may observe strange-looking address expressions which do not seem to make sense. What are these and how to fix/improve the pseudocode? Because on the CPU level there is no difference between an address and a simple number, distinguishing addresses and plain numbers is a difficult task which […]
Read MoreWhen working on a binary, you often recover types used in it from many sources: creating structures manually, from data, or using decompiler; parsing header files; importing them from type libraries or debug information; However, it may happen that eventually you discover duplicates. For example, you find out that the “custom” structure you’ve been […]

Traps are laid along the way, so keep your eyes open, your mind sharp, and capture the flag. Send us proof […]
Read MorePreviosuly, we’ve covered creating structures from C code using the Local Types window, however this may be not very convenient when you have complex types with many dependencies (especially of scattered over several fiels or depending on preprocessor defines). In such case it may be nore convenient to parse the original header file(s) on […]
