OpenSSF/OSV advisory MAL-2026-12796 confirms this npm version as malicious. The package's preinstall hook runs \`node index.js\`, which collects host identifiers (\`os.hostname()\`, \`os.userInfo().username\`, home directory, DNS servers) and reads \`/etc/passwd\` and \`/etc/hosts\` from the installer's machine, then POSTs the collected data over HTTPS to the hardcoded host \`pkdzrreksftymvx4d0o5olnxiooic80x.oastify.com\` (a Burp Collaborator out-of-band interaction domain)...

## Public findings

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

The package's preinstall hook runs \`node index.js\`, which collects host identifiers (\`os.hostname()\`, \`os.userInfo().username\`, home directory, DNS servers) and reads \`/etc/passwd\` and \`/etc/hosts\` from the installer's machine, then POSTs the collected data over HTTPS to the hardcoded host \`pkdzrreksftymvx4d0o5olnxiooic80x.oastify.com\` (a Burp Collaborator out-of-band interaction domain). The package name suggests a messaging utility, but no such functionality is present — the sole behavior on \`npm install\` is host reconnaissance and exfiltration to an attacker-controlled OAST endpoint.
