Can this skill help with malware analysis?

Yes, it includes patterns for identifying common malware protection techniques, such as VM detection, ptrace checks, and encrypted stack strings.

What is the Anti-Reversing Techniques skill?

It is a specialized capability for Claude Code that provides domain-specific guidance on identifying and bypassing software protection mechanisms like anti-debugging, packers, and code obfuscation.

What platforms are supported by these techniques?

The skill covers techniques for both Windows (API-based, PEB, and SEH detection) and Linux (ptrace and /proc/self/status checks).

Does it provide code for bypassing protections?

It includes implementation examples and bypass strategies using popular industry tools like x64dbg, IDAPython, and ScyllaHide.

Is this skill for legal use only?

Yes, the skill is intended strictly for authorized security research, CTF competitions, and legitimate penetration testing scenarios where you have explicit permission to analyze the software.

Security & Testing

Analyzes and bypasses software protection mechanisms, including anti-debugging, obfuscation, and VM detection.

About

This skill equips Claude with specialized knowledge to identify and navigate complex software protection layers encountered during malware analysis, authorized penetration testing, and security research. It provides implementation patterns for common anti-reversing tricks like PEB-based detection, timing-based VM checks, and control-flow flattening, while offering actionable bypass strategies using tools like x64dbg, ScyllaHide, and IDAPython. It is an essential resource for security professionals who need to deconstruct protected binaries and understand the inner workings of defensive or malicious code in a legitimate security context.

Key Features

Recognizes hardware, registry, and timing-based virtual machine (VM) detection methods.
Decodes control flow obfuscation like flattening, opaque predicates, and instruction substitution.
Provides methodologies for unpacking binaries protected by UPX, VMProtect, and Themida.
25,583 GitHub stars
Identifies Windows and Linux anti-debugging APIs and PEB-based detection flags.
Offers specific bypass scripts and hooks for x64dbg, IDAPython, and LD_PRELOAD.

Use Cases

Authorized penetration testing to evaluate the robustness of software protection schemes.
Malware analysis to uncover hidden functionality in protected or packed samples.
Academic security research and CTF challenges involving binary exploitation and deobfuscation.
