OpenSSF/OSV advisory MAL-2026-13743 confirms this npm version as malicious. On npm install, the package's postinstall hook runs \`node index.js\`, which POSTs installer host information — the absolute path of the package file (leaking the OS username and home directory layout), Node.js version, platform, and architecture — to a hardcoded Discord webhook at discord.com/api/webhooks/1530599209269465319/...

## Public findings

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

On npm install, the package's postinstall hook runs \`node index.js\`, which POSTs installer host information — the absolute path of the package file (leaking the OS username and home directory layout), Node.js version, platform, and architecture — to a hardcoded Discord webhook at discord.com/api/webhooks/1530599209269465319/. The webhook token is assembled via string concatenation at the call site to evade naive string matching. The destination is attacker-controlled and unrelated to the package's stated educational typo-catcher purpose, and there is no consent gate.
