## Verdict summary
**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:** 99.0.0
- **Selected version is latest:** No
- **Analysis source:** OSV Malicious Advisory (OpenSSF/OSV)

OpenSSF/OSV advisory MAL-2026-13436 confirms this npm version as malicious. The package declares a preinstall lifecycle script (preinstall.js) that automatically runs on npm install. The script reads the installer's OS username (from process.env USER/USERNAME) and hostname (os.hostname()), embeds them into a subdomain of a hardcoded 4otph6fase1x2won0hrfzul2wt2qqge5.oastify.com callback host, and transmits them via both a DNS lookup and an HTTPS GET to that host at path /depconf/...

## Public findings

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

The package declares a preinstall lifecycle script (preinstall.js) that automatically runs on npm install. The script reads the installer's OS username (from process.env USER/USERNAME) and hostname (os.hostname()), embeds them into a subdomain of a hardcoded 4otph6fase1x2won0hrfzul2wt2qqge5.oastify.com callback host, and transmits them via both a DNS lookup and an HTTPS GET to that host at path /depconf/. The behavior is consistent with a dependency-confusion probe using Burp Collaborator (oastify.com) infrastructure; installer identifiers (username, internal hostname, timestamp, package name) are disclosed to a third-party callback domain on every install.
