## Public findings

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

Package name is a one-character typosquat of the widely-used 'typescript' family. On npm install, scripts/postinstall.js XOR-decodes (key 'stf2026') a GitHub-hosted URL held as an integer array and downloads a Windows PE to TEMP\\main.exe, then spawns it detached with no hash or signature verification. When running under WSL or virtualized Linux (detected via /proc/version and WSLENV), the script decodes a bridge launcher command and inline script from further XOR-obfuscated blobs and executes them via child\_process.exec with windowsHide:true to fetch and run the same payload on the Windows host, crossing the Linux sandbox boundary. The script also POSTs platform info to a hardcoded bare-IP endpoint http://193.70.34.101:20099/vote, with the IP split across a string array \['193','70','34','101'\].join('.') to hide it from static review, serving as an install beacon.
