Binary exploitation1
Turn a memory-safety bug in a native binary into control of execution. Usually a stack overflow, a format string, or a heap primitive.
Same technique in picoCTF: Guessing Game 1, x-sixty-what, format string 3
Reverse engineering1
Work out what a compiled program does without its source, then work backwards from the check to the input that passes it.
Same technique in picoCTF: WinAntiDbg0x100, WinAntiDbg0x200, WinAntiDbg0x300
OSINT1
Answer a question about the real world from public sources. The work is pivoting between identifiers, not exploiting anything.
