Can it identify functionality in stripped binaries?

Yes, while stripped binaries lack symbol names, this skill uses import analysis, string extraction, and library dependency mapping to infer the binary's likely capabilities.

Which CPU architectures does it support?

It supports a broad range of architectures including ARM, AARCH64, x86, x86_64, MIPS, and others supported by the underlying rabin2 tool.

Is this skill meant for full decompilation?

No, this is a Phase 1 triage skill intended for rapid fingerprinting. It prepares the ground for deeper static or dynamic analysis tools.

Does it work on non-ELF files?

While optimized for ELF files and Linux-based firmware, it can perform basic fingerprinting on any executable or binary blob that rabin2 can parse.

What tools are required for this skill to function?

This skill primarily utilizes rabin2 (from the radare2 suite), the 'file' utility, and readelf to extract and parse binary metadata.

セキュリティとテスト

Identifies architecture, ABI, and potential capabilities of unknown binary files and firmware blobs using fast fingerprinting techniques.

概要

The binary-re:triage skill provides a standardized, high-speed workflow for the initial assessment of unknown binaries, ELF files, and firmware. By leveraging tools like rabin2 and readelf, it extracts critical metadata such as architecture (ARM, x86, MIPS), bit width, endianness, and libc dependencies in seconds. This skill is designed to establish a factual baseline before committing to time-intensive static or dynamic analysis, mapping imports to specific capabilities like network communication, cryptography, and file system access.
