## Public findings

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

This tarball, published under the popular \`cache-manager\` name, ships an obfuscated \`preinstall\` dropper that does not exist in the upstream project. \`package.json\` declares \`"preinstall": "node setup.mjs"\`, and \`setup.mjs\` is a single-line obfuscator.io-style bundle (string-array + RC4-style per-call decoder at \`i\['tXsWiG'\]\`) that hides every URL, filename, and command literal. Decoding reveals the loader detects the host platform, downloads a matching Bun runtime archive from \`github.com/oven-sh/bun/releases\` (e.g. \`bun-linux-x64-baseline\`, \`bun-windows-x64-baseline\`), extracts it to a temp directory, marks it executable, and then invokes that freshly downloaded runtime via \`execFileSync\` against the sibling file \`Math\_Symbol.js\`. \`Math\_Symbol.js\` is a 727 KB \`// @bun @bun-cjs\`-tagged opaque bundle with hex-obfuscated identifiers and its own string-array decoder; it is not referenced by the package's advertised entry point (\`dist/index.cjs\`) and is only reachable through the preinstall dropper. The alternate-runtime aspect (executing under Bun rather than Node) ensures the terminal payload is not observable to Node-based scanning of the tarball. The upstream \`cache-manager\` package ships no preinstall, no \`setup.mjs\`, and no \`Math\_Symbol.js\`, so this version is a supply-chain compromise or lookalike rather than a legitimate release. Installing this version causes attacker-controlled code to execute on the installer's machine at \`npm install\` time.
