anti-reversing-techniques

anti-reversing-techniques is a skill for Claude Code, Codex from RudyCity/superagent. It costs 66 tokens per session (826 once invoked), scanned A, original, MIT.

A guide to anti-reversing and obfuscation techniques encountered when examining software, including packed binaries and anti-debugging protections. It is intended for authorized malware analysis, security research, penetration testing, or CTF work.

In plain words
What is it for?
Use it to analyze software you are authorized to examine, study malware evasion, work on a security challenge, or build security research tools.
Why use it?
It helps analysts understand protections that make executable code harder to inspect, while requiring permission and a defined legal scope.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

anti-reversing-techniques scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AUTHORIZED USE ONLY: This skill contains dual-use security techniques. Before proceeding with any bypass or analysis:

  1. Verify authorization: Confirm you have explicit written permission from the software owner, or are operating within a legitimate security context (CTF, authorized pentest, malware analysis, security research)
  2. Document scope: Ensure your activities fall within the defined scope of your authorization
  3. Legal compliance: Understand that unauthorized bypassing of software protection may violate laws (CFAA, DMCA anti-circumvention, etc.)

Legitimate use cases: Malware analysis, authorized penetration testing, CTF competitions, academic security research, analyzing software you own/have rights to

Anti-Reversing Techniques

Understanding protection mechanisms encountered during authorized software analysis, security research, and malware analysis. This knowledge helps analysts bypass protections to complete legitimate analysis tasks.

Input / Output

What you provide:

  • Binary path or sample: the executable, DLL, or firmware image under analysis
  • Platform: Windows x86/x64, Linux, macOS, ARM — affects which checks apply
  • Goal: bypass for dynamic analysis, identify protection type, build detection code, implement for CTF

What this skill produces:

  • Protection identification: named technique (e.g., RDTSC timing check, PEB BeingDebugged) with location in binary
  • Bypass strategy: specific patch addresses, hook points, or tool commands to neutralize each check
  • Analysis report: structured findings listing each protection layer, severity, and recommended bypass
  • Code artifacts: Python/IDAPython scripts, GDB command sequences, or C stubs for bypassing or implementing checks

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

anti-reversing-techniques is a skill published in the GitHub repository RudyCity/superagent (21 stars, last pushed yesterday), licensed MIT. It adds 66 tokens to every session and 826 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
