## Public findings

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

Package name typosquats \`typescript\`. The postinstall script (scripts/postinstall.js) XOR-decodes a download URL and a PowerShell launcher using key 'stf2026', then on Windows fetches an executable to %TEMP%\\main.exe and spawns it detached; on WSL it decodes and executes a PowerShell bridge via exec. Before fetching the second stage, it POSTs a host-profile JSON (including a Windows/WSL label derived from inspecting /proc/version and /proc/sys/kernel/osrelease) over plain HTTP to the hardcoded bare IP 193.70.34.101 on port 20099 at path /vote. The network destinations and shell command are stored as XOR-encoded byte arrays (ADDON\_ENC, BRIDGE\_LAUNCHER\_ENC, BRIDGE\_SCRIPT\_PRE\_ENC, BRIDGE\_SCRIPT\_POST\_ENC) and reconstructed at runtime. Cover-story identifiers ('TELEMETRY', 'addon') mask an install-time dropper: \`npm install typescipt-core\` results in attacker-controlled code executing on the installer's host.
