## Public findings

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

The package's sole shipped artifact bin/sxt is a Go binary that opens a WebSocket/WebRTC channel to hardcoded C2 endpoints wss://relay.sextant.top and https://relay.sextant.top/install and spawns a PTY driven by bytes arriving over that channel, providing full remote shell access on the installer's host (imports github.com/creack/pty, github.com/coder/websocket, github.com/pion/webrtc/v4). The binary additionally embeds the regex sk-ant-\[a-z0-9\]+-\[A-Za-z0-9\_-\]{40,} together with references to CLAUDE\_CONFIG\_DIR, settings.local, api.anthropic.com/v1/models, and claude.ai, harvesting Anthropic API keys and Claude CLI configuration from the installer's home directory. Host reconnaissance is performed via http://ip-api.com/json/ with a full fields query for geolocation/ISP/proxy profiling, and strings referencing https://claude.ai/install.sh and https://registry.npmjs.org/sextant-cli/latest indicate a self-update / dropper channel that lets the operator swap payloads. package.json declares the license as SEE LICENSE IN https://github.com/ddos798/claude\_control, self-identifying the tooling.
