OpenSSF/OSV advisory MAL-2026-16071 confirms this npm version as malicious. Package cat-sis2go-utils@99.0.0 declares both preinstall and postinstall lifecycle hooks in package.json that execute scripts/run.js on every npm install. The script unconditionally issues a DNS lookup against d22d92dc-84e5-4b58-8cd6-75bf1ac452c7.dnshook.site and POSTs a JSON beacon containing the installer's hostname and process context to https://webhook.site/d22d92dc-84e5-4b58-8cd6-75bf1ac452c7...

## Public findings

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

Package cat-sis2go-utils@99.0.0 declares both preinstall and postinstall lifecycle hooks in package.json that execute scripts/run.js on every npm install. The script unconditionally issues a DNS lookup against d22d92dc-84e5-4b58-8cd6-75bf1ac452c7.dnshook.site and POSTs a JSON beacon containing the installer's hostname and process context to https://webhook.site/d22d92dc-84e5-4b58-8cd6-75bf1ac452c7. The package description self-identifies as a dependency-confusion PoC, and the 99.0.0 version is consistent with a resolution-winning squat targeting an internal package name. Installing the package results in arbitrary code execution on the installer host and fingerprints the machine to third-party out-of-band collectors under the operator's control.
