The binary here is actually a pretty good example of why you shouldn’t always rely on automated tools because they (usually) only think of one way to exploit a binary and might miss more “creative” ways. And it’s short enough that you can actually read the whole disassembly without getting bored.

Disassemble the code and take a look at the disassembly. A good disassembler will tell you what functions get called from what places and also what functions don’t get called.
