SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps you identify and bypass common ELF binary defenses (ASLR, PIE, NX/DEP, stack canary, RELRO, FORTIFY_SOURCE, CET, and ARM MTE) so you can progress from vulnerability to working exploitation despite modern mitigations.

Core Features & Use Cases

  • Protection identification via checksec-style signals: quickly map observed binary/OS indicators to likely mitigations that block typical payloads.
  • Tactic selection by defense combination: choose appropriate leak and write primitives depending on the protection mix (single vs. chained mitigations).
  • Actionable bypass playbooks: provides bypass methods and required primitives for each protection, plus multi-protection scenario recipes (e.g., NX+ASLR+Canary+Full RELRO+PIE).
  • Cross-reference matrix for rapid lookup: use the provided matrix to connect a specific protection to working bypass techniques and the primitive needed.

Quick Start

Load the Skill and then use it to map your binary’s checksec/protections output to the correct leak/write/ROP strategy before attempting exploitation.

Frequently Asked Questions about binary-protection-bypass

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I bypass NX and ASLR when exploiting an ELF binary?▼

To bypass NX and ASLR on an ELF binary, you use leak primitives to defeat address randomization and ROP or ret2libc chains to execute code despite NX restrictions. The correct tactic depends on the exact protection combination detected.

What is the best way to choose a bypass technique for multiple chained ELF mitigations?▼

Choosing a bypass technique for chained ELF mitigations involves mapping the protection mix to matched primitives using a cross-reference matrix. This connects mitigations like Full RELRO and PIE to specific leak, write, or data-only attack strategies.

How do I identify binary protections before attempting an exploit?▼

You identify binary protections by analyzing checksec-style signals from the ELF file and OS environment. This maps observed indicators to likely mitigations such as stack canaries, FORTIFY_SOURCE, CET, or ARM MTE that block typical payloads.

Can I use ret2dlresolve to bypass Full RELRO and NX?▼

Yes, ret2dlresolve is a provided bypass primitive for scenarios involving NX and RELRO. You can use this technique to resolve symbols dynamically when Full RELRO prevents direct Global Offset Table overwrites.

Does this bypass approach work for ARM MTE and CET mitigations?▼

Yes, the bypass playbooks apply to ARM MTE and CET mitigations. When these protections are detected singly or in combination, the system provides matched primitives like data-only targets or brute-force retry strategies to drive the next exploit step.
