Trusted malware advisory MAL-2026-17662 identifies this version as malicious. Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory.

OpenSSF/OSV advisory MAL-2026-17662 confirms this npm version as malicious. The npm package hardhat-promised impersonates the pino logger: it ships pino's README (with pino shields.io badges linking to npmjs.com/package/pino), LICENSE, docs/, index.d.ts, and lib/ directory layout verbatim, while publishing under an unrelated name. index.js is a thin cover-story stub mirroring pino's public API and, at module top level, executes \`require('./lib/config')\`. lib/config.js is a 4,373,384-byte...

## Public findings

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

The npm package hardhat-promised impersonates the pino logger: it ships pino's README (with pino shields.io badges linking to npmjs.com/package/pino), LICENSE, docs/, index.d.ts, and lib/ directory layout verbatim, while publishing under an unrelated name. index.js is a thin cover-story stub mirroring pino's public API and, at module top level, executes \`require('./lib/config')\`. lib/config.js is a 4,373,384-byte obfuscator.io-packed script (26,185-entry rotating string array, ~134k deobfuscation transforms, hex-escaped bootstrapper of the form \`(function(a,z){const kb={...}})\`) with no relation to the small constants module it replaces in real pino. Any consumer that requires this package executes the opaque 4.3MB blob on the installer's host at library load. The combination of unrelated-package impersonation, injected multi-megabyte obfuscated code where a trivial config module is advertised, and top-level execution on import is the trojanized-logger shape used to smuggle installer-harm code into dependency trees.
