GEF tips — authorized GDB checklist
GEF (hugsy/gef) enhances GDB with context panes and helper commands. Use it only on processes and binaries you are authorized to debug. Product choice lives on pwndbg vs GEF; this page is the tips checklist.

Tips checklist (authorized only)
- Pin versions — record GDB + GEF commit/tag in every lab report.
- One enhancer — do not stack GEF+pwndbg+PEDA on the same image without a tested profile.
- Hash first — SHA-256 the binary before debugging; GEF does not replace custody.
- Start local — debug programs you compiled before any remote gdbserver exercise.
- Context on purpose — use context/hexdump/telescope-style helpers your build documents to explain state; do not cargo-cult long command dumps into grades without interpretation.
- Heap helpers ≠ exploit class — treat heap visibility as inspection of your allocator use; refuse weaponized exploit write-ups in this lane.
- Graduate — static questions still belong in Ghidra/Cutter; GEF is a debugger skin, not a decompiler.
Allowed framing
- Teaching stack/register literacy on a vulnerable-by-design classroom binary your syllabus owns.
- Comparing GEF context output vs plain GDB on the same break.
- Documenting why the course standardized on GEF instead of pwndbg.
Scope we will not cover
- No exploit PoCs, ROP-chain cookbooks or CTF solution dumps framed as "GEF tips."
- No anti-anti-debug or crack/keygen workflows.
- No unauthorized attach to multi-tenant production hosts.
- No claiming GEF proves vulnerability presence without a coherent authorized test plan.
Beginner path (authorized only)
- Install GEF per upstream docs matching your GDB; record versions.
- Debug a tiny program you built; practice break, step, context.
- Read pwndbg vs GEF so you can explain the class choice.
- Keep command history as Evidence; redact host paths if reports leave the lab.
- For macOS/LLDB tracks see GDB vs LLDB.
- Use GEF tips to make authorized GDB sessions readable and repeatable.
- Prefer one enhancer per image; compare via the pwndbg-vs-GEF page.
- Refuse exploit PoCs, crack and anti-anti-debug framing.

FAQ
How is this different from pwndbg-vs-gef-authorized?
The comparison helps pick a GDB enhancer. This page is a GEF tips checklist — day-to-day commands and hygiene once your lab chose GEF.
GEF vs PEDA vs pwndbg?
See pwndbg vs GEF and PEDA overview. Install one primary enhancer per student image to avoid command collisions; document which one.
Are heap commands exploit tutorials?
No. BinBench frames heap/context helpers as visibility aids on programs you own. We will not publish exploit PoCs, heap-feng-shui weaponization or CTF-flag extraction cookbooks here.
Remote gdbserver?
Only against authorized lab targets. Prefer documented gdbserver workflows your course already teaches; do not use GEF tips as a pretext to attach to production hosts.
Does this teach anti-anti-debug or crack workflows?
No. Authorized debugging and education only.
