tokio — deep security report

ShadowCanopy's full breakdown of tokio on crates.io: verdict, AI analysis, dependency chain, network behavior, prebuilds, and obfuscated code.

All findings are false positives from a naive regex on 'F::' (Rust generic associated type syntax in spawn/block_on signatures). The source is the legitimate Tokio runtime; no network, exfil, or malicious behavior present.

AI breakdown

Plain-English summary of what this package does and how it behaves.

tokio 1.54.1 is the source package for the Tokio asynchronous runtime for Rust, providing async primitives and I/O support including filesystem operations.

Capabilities

  • Provides async filesystem operations
  • Supports blocking I/O
  • Includes reactor and documentation modules

Data access

  • Filesystem

Network

  • Hardcoded public IP in network code

Package is the standard Tokio crate with no scripts or declared dependencies; static findings flag repeated hardcoded public IPs in network code, which should be reviewed in context of the full source.

Security findings (4)

Static analysis rule matches, with the exact code that triggered them.

How ShadowCanopy checks crates.io packages

ShadowCanopy blocks every dependency by default and only lets through what it can verify — against live malicious-package advisories, an AI behavior scan, and a byte-for-byte hash check. It protects installs across npm, PyPI, crates.io, pkg.go.dev, RubyGems, Maven Central, NuGet, Packagist, Hex, pub.dev, Swift Package Manager.
