Lab Path
RE path diagram for YOUR $RE_LAB binary — static to dynamic to crackme to anti-analysis to writeup with ethics gates.
Visual · t23_lab_path
Lab path = visual RE chain on authorized binary. Original Cyberlium.
Opening
Draw the path from hash verify to share-safe writeup — with red stop signs at piracy shortcuts.
Document RE path: legal verify → static triage → Ghidra/objdump → dynamic GDB → crackme solve optional patch YOUR toy → anti-analysis document → writeup → share-safe export. Ethics gates: undocumented sample, commercial piracy, DRM bypass, casual live crackme share — refused paths labeled. UTC milestones and artifact IDs per station. Mermaid or sketch chmod 600. Honest N/A segments if brief restricted dynamic — no fiction. Defender breakpoint: where static or anti-debug finding would inform detection.
1. Path stations
Intake, static, dynamic, crackme, anti-analysis, writeup, share — seven minimum.
Each station links evidence index row and module lesson ID.

═══ INSTALL ═══
Linux (Debian/Ubuntu):
Command — copy this
sudo apt install binutils
macOS: Built-in (Xcode CLI) or brew install binutils Built-in or brew install binutils
Windows: Use WSL binutils
═══ LINUX / macOS ═══
Command — copy this
export LAB_RE=${LAB_RE:-$HOME/cyberlium-lab/t23-re}
cat > "$LAB_RE/notes/lab-path.txt" <<'EOF'
done: hello/check/branch/crackme/antidebug/obfusc
static: file strings xxd objdump readelf nm
dynamic: gdb break/step/disassemble
next: crackmes.one level 1 YOUR choice — never commercial
EOFCommand — copy this
objdump -d "$LAB_RE/bin/crackme" | grep -E '<main>|strcmp' | head -6 nm "$LAB_RE/bin/crackme" | grep main grep -E 'done|next|never' "$LAB_RE/notes/lab-path.txt"
Primary tools to practice this lesson: objdump, nm. Reference sites: Lab path (https://pwn.college/); objdump workflow (https://sourceware.org/binutils/docs/binutils/objdump.html); crackmes.one (https://crackmes.one/). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.
2. Ethics overlay
Red stops at piracy, commercial patch, DRM strip, unauthorized target.
YOUR-toy patch branch only when documented separately.
3. Purple breakpoint
Mark where blue benefits: suspicious import, ptrace use, packer entropy — literacy handoff.
One paragraph detection uplift from YOUR $RE_LAB path.
4. What you ship: lab path diagram
RE path with ethics gates + UTC milestones — chmod 600.
5. What you record before the next lesson

6. Wrong vs right: commercial piracy vs crackmes/CTF toys
Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.
Wrong
Lab path includes commercial crack shortcut lane.
Right
Lab path documented for $RE_LAB binary. Next: Evidence Pack.
Mission: lab path diagram
1) Map seven stations. 2) Add four ethics gates. 3) UTC milestones per station. 4) Link evidence index IDs.
