Quick answer

GDB Python scripting powers pretty-printers and helper commands inside GDB. Use these tips only on processes you are authorized to debug. Layout tips stay on gdb-tui-tips; plugin UX on GEF tips.

Tip checklist (authorized only)

  1. Record gdb --version and whether Python support is enabled in your build.
  2. Load only reviewed pretty-printers/helpers from trusted lab paths.
  3. Prefer small scripts that print structures for courseware binaries you built.
  4. Quote source/python invocations into Evidence for reproducibility.
  5. If you need richer UX, compare GEF — still authorized-only.
  6. Never ship "hide from debugger" helpers as coursework solutions.

Allowed framing

  • Teaching pretty-printers for a student C++ class type on a lab VM.
  • Automating repetitive print sequences during authorized debugging.
  • Comparing GDB Python with LLDB Python as toolchain packaging.
  • Saving printer scripts hashed beside the case binary.

Scope we will not cover

  • No anti-anti-debug / stealth debugger scripts.
  • No crack/keygen helpers.
  • No exploit PoC automation.
  • No unauthorized attach to production processes.

Beginner path (authorized only)

  1. Confirm GDB has Python scripting on the lab image.
  2. Debug an authorized hello/course binary; print a struct manually once.
  3. Load one syllabus-approved pretty-printer; confirm the display change.
  4. Save the script + gdb version into the case binder.
  5. Optional: compare with GEF tips on the same binary.
Which to pick
  • Use GDB Python for authorized display/helper automation, not stealth or exploits.
  • Prefer TUI/GEF pages for UI layers; this page for Python hygiene.
  • Authorized targets only.

FAQ

How is this different from gdb-tui-tips / gdb-gef-tips?

GDB TUI tips cover stock TUI layout; GEF tips cover the GEF plugin layer. This page is GDB's own Python API hygiene for authorized labs.

Pretty-printers vs GEF?

Pretty-printers customize how values display in stock GDB. GEF is a broader plugin UX. You can use either (or both) when lab policy allows — record what loaded.

GDB Python vs LLDB Python?

Different APIs. See LLDB Python for LLVM-side scripting — do not invent a shared bridge.

Can Python scripts bypass anti-debug for piracy?

No. BinBench will not publish anti-anti-debug or crack cookbooks.

Does this teach exploit automation?

No. Authorized debugging aids only — no exploit PoCs.
