**Blocked & quarantined** — Quarantined by product-default policy — this version is not allowed through the firewall.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Malware
- **Selected version:** 0.3.5
- **Selected version is latest:** No
- **Analysis source:** OSV Malicious Advisory (OpenSSF/OSV)

OpenSSF/OSV advisory MAL-2026-14064 confirms this npm version as malicious. Package publishes under a lodash-imitating identity: keywords \`lodash\`/\`lodash-js\`, and the README is a verbatim copy of the official lodash 4.18.1 README. The single shipped file \`dist/common-js.js\` is not lodash — it is a ~770 KB javascript-obfuscator bundle (17,969-entry rotated string array, \`\_0xNNNN\` identifiers)...

## Public findings

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

Package publishes under a lodash-imitating identity: keywords \`lodash\`/\`lodash-js\`, and the README is a verbatim copy of the official lodash 4.18.1 README. The single shipped file \`dist/common-js.js\` is not lodash — it is a ~770 KB javascript-obfuscator bundle (17,969-entry rotated string array, \`\_0xNNNN\` identifiers). After deobfuscation the bundle is a browser-based cryptocurrency-mining client: it opens a WebSocket to a caller/config-supplied pool URL, spawns a fan-out of Web Workers keyed by \`workerId\`, handles \`nonce\` framing, and bundles an AES-GCM decryption primitive (\`aesGcmDecrypt\` from @noble/ciphers) for pool message decryption. Wallet and worker identifiers are read from a config object with fallbacks (\`cfg.wallet||'x'\`, \`cfg.worker||'worker'\`). A developer who installs this expecting a lodash-family utility and ships it in a web application will silently mine cryptocurrency on their end users' browsers, consuming visitor CPU/battery and creating a compliance/abuse liability for the downstream site. The identity masquerade (name/keywords/README all mimicking lodash) combined with heavy string-array obfuscation of the real payload is the standard shape of a supply-chain masquerade attack.
