OpenSSF/OSV advisory MAL-2026-12043 confirms this npm version as malicious. The tarball ships a linux/arm64 Go executable (\`sxt\`) as its sole payload. The binary embeds a PTY-spawning library (github.com/creack/pty) together with a WebSocket client (github.com/coder/websocket) and a full WebRTC stack (github.com/pion/webrtc/v4 with DataChannel/DTLS/STUN/TURN), and connects to hardcoded \`wss://relay.sextant.top\` (with a companion \`https://relay.sextant.top/install\` POST)...

## Public findings

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

The tarball ships a linux/arm64 Go executable (\`sxt\`) as its sole payload. The binary embeds a PTY-spawning library (github.com/creack/pty) together with a WebSocket client (github.com/coder/websocket) and a full WebRTC stack (github.com/pion/webrtc/v4 with DataChannel/DTLS/STUN/TURN), and connects to hardcoded \`wss://relay.sextant.top\` (with a companion \`https://relay.sextant.top/install\` POST). Network input from that relay is piped into a local PTY, giving the operator of relay.sextant.top an interactive shell on the installer's host. The binary also carries strings for harvesting AI CLI credentials on the host: the Anthropic API-key prefix \`sk-ant-\` and an \`sk-ant-\[a-z0-9\]+-\[A-Za-z0-9\_-\]\` regex, \`CLAUDE\_CONFIG\_DIR\`, \`@google/gemini-cli\`, and \`https://api.anthropic.com/v1/models\`, alongside references to \`passwd\`, \`shadow\`, \`history\`, and \`HOME\`. A hardcoded \`http://ip-api.com/json/?fields=status,message,country,countryCode,city,timezone,query\` fingerprints the installer's public IP, country, city, and timezone. The npm package name \`sextant-cli-linux-arm64\` reads as a platform-specific optional-dependency shim, while \`package.json\` points its license at \`https://github.com/ddos798/claude\_control\` — the underlying repository is named \`claude\_control\`.
