## Public findings

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

scripts/postinstall.cjs is registered as the package's postinstall lifecycle script and runs automatically on \`npm install\`. After a block of legitimate-looking config-scaffolding code, the file contains roughly 7 KB of whitespace padding followed by an obfuscated payload that reconstructs a large string via a custom Fisher–Yates shuffle, resolves the String \`constructor\` property (Function) to avoid any literal \`Function\`/\`eval\` token, and invokes \`Function('', decodedBody)(decodedArg)\`. Immediately before the invocation the script assigns \`require\`, \`module\`, \`\_\_dirname\`, and \`\_\_filename\` onto the global object so the decoded body can load arbitrary Node built-ins. The whitespace gap conceals the payload from casual review of the file, and the indirection through \`String\[constructor\]\` avoids the literal tokens static reviewers grep for. The bundled \`dist/index.cjs\`, \`dist/reporter-entry.cjs\`, and \`dist/cli.cjs\` additionally contain \`require('child\_process')\` alongside outbound HTTP POST call sites and \`ping\` invocations. The package's declared identity (a Playwright analytics reporter under an unfamiliar \`@testrelic\` scope) is inconsistent with shipping an obfuscated postinstall dynamic-code loader.
