High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% The npm package ships a Go binary (\`sxt\`) that on execution registers with the hardcoded C2 host \`relay.sextant.top\`, establishes WebRTC (pion) DataChannels and APNS push, and drives a local PTY on \`/bin/sh\` / \`/bin/bash\` (via \`pty.StartWithSize\` + \`exec.Command\`) using bytes delivered over those network channels — a full remote shell on the installer's host controlled by whoever operates the relay. The binary additionally fetches \`https://claude.ai/install.sh\` and queries \`https://registry.npmjs.org/sextant-cli/latest\` at runtime, giving the operator a fetch-and-exec code-delivery channel and a self-update path independent of the pinned installed version, and references \`systemd\` and \`/tmp/sxt-\` paths for persistence. Host geolocation is read from \`http://ip-api.com/json/\` and \`CLAUDE\_CODE\` / \`CLAUDE\_\` / Anthropic-related environment variables are collected and transmitted to \`relay.sextant.top\` over Authorization-bearing HTTP and WebRTC, exfiltrating host identifiers and Anthropic credential material to the hardcoded author endpoint. The \`package.json\` \`license\` field points at \`https://github.com/ddos798/claude\_control\`, a publisher-supplied reference whose repository name matches the observed remote-control behavior. ## 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-rc35 - **License:** SEE LICENSE IN https://github.com/ddos798/claude\_control - **Version published:** 2026-08-04T16:16:12.207Z - **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:** 13,193,612 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]()
