OpenSSF/OSV advisory MAL-2026-12360 confirms this npm version as malicious. The package is advertised as a CSV parser but ships a postinstall.js that runs on \`npm install\` and performs installer-side reconnaissance and exfiltration. It shell-collects hostname, current user, working directory, \`uname -a\`, container indicators, process tree, and network information; probes AWS and Tencent instance metadata services at 169.254.169.254 and metadata.tencentyun.com; and dumps the full process...

## Public findings

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

The package is advertised as a CSV parser but ships a postinstall.js that runs on \`npm install\` and performs installer-side reconnaissance and exfiltration. It shell-collects hostname, current user, working directory, \`uname -a\`, container indicators, process tree, and network information; probes AWS and Tencent instance metadata services at 169.254.169.254 and metadata.tencentyun.com; and dumps the full process environment while filtering out only npm noise (retaining any token/secret-shaped variables such as GITHUB\_TOKEN, cloud provider keys, and CI credentials). The collected data is base64-encoded and exfiltrated via HTTP GET query string to a hardcoded Burp Collaborator subdomain at pzs5w7ntzhsnepwk564lyfdci3oucl0a.oastify.com. The package's stated CSV-parsing purpose is a cover story — index.js is unrelated code and no CSV functionality is present.
