Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Analyzing Rust Malware Internals
When to Use
- You have a Rust-compiled binary and need to confirm the toolchain, demangle symbol names, and
enumerate crate dependencies.
- Standard analysis is hampered by Rust's name mangling and large static linking.
Do not use this for non-Rust binaries — confirm the Rust signature first. This skill reads the binary statically and executes nothing.
Prerequisites
- The Rust binary (read inertly).
Safety & Handling
- Read bytes statically; treat strings as untrusted.
Workflow
Step 1: Confirm Rust and toolchain
python scripts/analyst.py info sample.binLooks for rustc/cargo markers, the rust panic/unwind strings, and embedded source paths (/rustc//library/..., ~/.cargo/registry/...).
Step 2: Demangle symbol names
Detects v0 (_R...) and legacy (_ZN...17hE) mangled symbols and demangles them to readable paths.
Step 3: Enumerate crates
Extract crate names/versions from .cargo/registry/src/.../-/ paths to fingerprint capabilities (e.g., reqwest, tokio, aes, winapi).
Step 4: Map and document
Map notable crates to behavior and ATT&CK.
Validation
- The Rust toolchain signature is confirmed before demangling.
- Demangled names are readable module paths (not still-mangled).
- Crate names/versions are plausible registry entries.
Pitfalls
- Mixing v0 and legacy mangling in one binary — handle both.
- Stripped binaries where only registry path strings remain.
- Static crates inflating the symbol set; focus on the author's crate/
main.
