## Public findings

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

typscript-cli is a typosquat of 'typescript' (index.js exports an empty object; no library functionality). Its scripts/postinstall.js is the only functional code and executes on npm install. It XOR-decodes (key 'stf2026') four embedded numeric arrays to reconstruct a download URL and a PowerShell 'bridge' command, downloads a Windows executable to %TEMP%\\main.exe, and spawns it detached with windowsHide:true. On WSL/Linux hosts it uses child\_process.exec with the XOR-decoded PowerShell bridge command to drop and run the same payload on the Windows side. The same postinstall also POSTs a platform label to a hardcoded bare-IP endpoint 193.70.34.101:20099/vote over plain HTTP, with the host assembled from a split array \['193','70','34','101'\].join('.') to evade literal-string scanning. There is no publisher-matched destination, no version pinning, and no integrity check on the fetched binary.
