OpenSSF/OSV malware advisory MAL-2026-6471 identifies this version as malicious and supplies the Firewall block.

OpenSSF/OSV advisory MAL-2026-6471 confirms this npm version as malicious. The package's documented entry point \`index.ts\` begins with \`import './src/bootstrap';\`, which causes \`src/bootstrap.js\` to run whenever the module is required or imported. \`src/bootstrap.js\` is a custom string-shuffle obfuscator: a function \`YWG(x)\` deterministically unscrambles opaque string literals (e.g. \`YWG('axhscuutcrogycrneotisjlnkdpfqmzovtrwb').substr(0,11)\` reconstructs the literal \`'constructor'\`), then...

## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

The package's documented entry point \`index.ts\` begins with \`import './src/bootstrap';\`, which causes \`src/bootstrap.js\` to run whenever the module is required or imported. \`src/bootstrap.js\` is a custom string-shuffle obfuscator: a function \`YWG(x)\` deterministically unscrambles opaque string literals (e.g. \`YWG('axhscuutcrogycrneotisjlnkdpfqmzovtrwb').substr(0,11)\` reconstructs the literal \`'constructor'\`), then uses \`Function.prototype.constructor\` to build a \`Function\` from one shuffled blob, executes it on a second shuffled blob, and invokes the result via \`XZs(7942)\`. Before invoking the constructed code the bootstrap explicitly re-exposes Node capabilities to it via \`global\['r'\]=require; global\['m'\]=module;\`, granting the dynamically generated payload full filesystem, child\_process, and network access. The package's advertised purpose is straightforward Tailwind color-shade math — a few dozen lines of pure arithmetic — so a hand-rolled string-shuffle obfuscator wrapping \`Function\`-constructed code at import time has no legitimate purpose. This is the standard supply-chain attack shape: opaque payload, evasion-only obfuscation, automatic execution on consumer import, full Node capability re-export.
