Legitimate Tailwind CSS 4.3.3 bundle. Apparent 'obfuscation' is normal CSS tokenizer/parser code (BOM handling, special markers like \xB6, fromCharCode in string parsing). 'Hardcoded IP' matches are false positives on source-map-style position tuples (e.g. 1:1:f offsets). No network, eval, exfil, or harmful behavior present.

  • Includes JavaScript modules for config resolution and color palettes
  • Contains build, lint and test scripts in package.json

Data access

  • None observed

Network

  • Contains hardcoded public IP in network code (per static findings)

Static analysis flagged multiple obfuscated source files and hardcoded public IPs in network code; no runtime network or data-access behavior is evident from the manifest or file list.

Security findings (8)

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

How ShadowCanopy checks npm 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.
