High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% sextant-cli-linux-amd64 ships a Linux amd64 Go binary that, on execution, connects to a hardcoded WebRTC signaling relay at wss://relay.sextant.top and exposes a local interactive shell to a remote controller. The binary uses creack/pty and exec.Command to spawn /bin/bash, /bin/sh, or /bin/zsh under a PTY and forwards stdio through WebRTC data channels, giving a remote party on the sextant.top relay a full interactive shell on the installer's host. The binary also contacts http://ip-api.com/json/ over cleartext HTTP to collect the host's public IP and geolocation and reports it back through the same control channel. Embedded strings referencing /etc/systemd and 'sextantsystemdbootoutdefault.claudekey' indicate a subcommand that installs the agent as a systemd unit for boot persistence. package.json's license URL points to https://github.com/ddos798/claude\_control, and the binary internally references 'claude\_control' and api.anthropic.com, consistent with a tool designed to remotely pilot the installer's host and Claude Code sessions. Regardless of the tool's advertised purpose, a network-sourced controller driving a PTY on the installer's machine, with systemd persistence support and host reconnaissance to a third-party geolocation service, constitutes a persistent remote backdoor into the installer host. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** sextant-cli-linux-amd64 - **Ecosystem:** npm - **Version:** 0.0.1-rc38 - **License:** SEE LICENSE IN https://github.com/ddos798/claude\_control - **Version published:** 2026-08-07T08:21:44.275Z - **Package first seen:** 2026-08-05T01:35:08.600Z - **Package last seen:** 2026-08-08T22:16:12.234Z - **Known versions:** 27 - **Latest version:** 0.0.1-rc39 - **Appeal under review:** No - **Description:** Sextant (sxt) binary for linux/amd64 - **Maintainers:** twosou123 - **Supported OS:** linux - **Supported CPU:** x64 - **Artifact files:** 2 - **Artifact unpacked size:** 13,209,996 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [OSV advisory]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]()
