ZETA CYBERLAB V5.0：將任何 LLM 轉化為逆向工程助手的系統提示詞開源

If you've ever tried to use ChatGPT / Claude / DeepSeek / GLM for binary analysis, you know the pain:

It hallucinates APIs and offsets ("this function calls CheckRemoteDebuggerPresent at 0x4012A0" — no it doesn't)
It gives surface-level textbook answers instead of a real analysis workflow
Every session starts from zero — no structure, no methodology

So I built ZETA CYBERLAB V5.0 — a single, production-ready system prompt that fixes this. It's open source and MIT licensed:

What it does

Paste the prompt into your model's system prompt slot (Custom Instructions, Claude Projects, assistant persona — anything that accepts one), and the model becomes "Zo": a senior reverse engineer with a fixed methodology.

It ships with 12 modules:

Binary Analysis Engine — PE32/PE32+, ELF, Mach-O: headers, sections, IAT/EAT, relocations, TLS callbacks
Assembly & Decompilation — x86/x64/ARM/ARM64, calling conventions (cdecl/stdcall/SysV/AAPCS), stack frames, SIMD, pseudo-code reconstruction
Dynamic Debugging — x64dbg, WinDbg, GDB, LLDB, IDA, Ghidra, Binary Ninja; breakpoint selection strategy included
Protection Analysis — packers (UPX & custom), control-flow flattening, VM-based protection, anti-debug techniques (PEB checks, RDTSC), integrity checks
License System Design Audit — from a defensive perspective: signature schemes, device binding, token lifecycle, hardening advice
Memory & Runtime — VTable/object layout, ASLR/DEP/Canary/CFG
Tool Development — Capstone, Keystone, Unicorn, LIEF, pefile, Frida, angr, YARA, Ghidra API
Patching & Compatibility — binary diff, hot patching, ABI issues
Automated 7-Step Workflow — identification → structure → static → dynamic → logic reconstruction → validation → report
Standardized Output Format — every complex answer comes as: target analysis / principles / process / code / run instructions / verification / troubleshooting / conclusions
Research Integrity (the important one)
Expert Modes — auto-switches between static / dynamic / packer / tooldev modes per task

The anti-hallucination module is the real gem

Module 11 is mandatory and specifically targets LLM failure modes in this domain:

❌ Never fabricate disassembly output
❌ Never fake debugger output or pretend code was executed
❌ Never invent functions/APIs that don't exist
✅ Unverified conclusions must be explicitly labeled as speculation
✅ Missing files/logs → say so, state assumptions upfront
✅ Unauthorized key extraction / access-control bypass → refuse, pivot to defensive analysis

This makes the difference between "confident nonsense" and an assistant that actually tells you what it verified vs. what it's guessing — which is exactly what you need when reading a disassembly at 2 AM.

Example: what a session looks like

You paste:

Here's a Ghidra decompilation of a function from my own tool, it crashes when input length > 64. [paste pseudocode]

The assistant automatically enters the workflow: identifies what it can verify from the code, walks through stack frame analysis, pinpoints the suspect buffer handling, labels each claim as fact/speculation, and ends with concrete steps to validate in x64dbg (breakpoint location + what to watch).

Legal / ethical note

The prompt is scoped to legitimate scenarios only: your own software, authorized assessments, CTF challenges, isolated lab environments, and defensive research. It explicitly instructs the model to refuse unauthorized license bypass or credential extraction. Use it within your local laws and the target software's license terms.
