Allowed framing
- Debugging your binaries, CTF challenges, or samples under written authorization.
- Teaching GDB workflows in a classroom with licensed/owned targets.
- Incident-response debugging under ticketed approval.
Scope we will not cover
- No step-by-step exploit PoCs, heap-note recipes against third-party products, or anti-cheat bypass.
- No “pwndbg crackme solutions pack” mirroring.
- Mentions of exploit development appear only as refusals.
Which to pick (high level)
- Pick pwndbg when you want active upstream releases and documented LLDB paths alongside GDB.
- Pick GEF when your lab already standardizes on GEF’s command set and yearly tags.
- Either way, start from stock GDB vs LLDB skills first — helpers do not replace authorization.
For legal, authorized and educational use only.
