High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% The package is a platform-specific leaf (linux/arm64) whose only shipped artifact is a 12 MB stripped Go binary at bin/sxt. The package.json omits repository, author, main, bin, files, and scripts fields, and its license field points at github.com/ddos798/claude\_control — a self-labeled 'claude\_control' project. Strings in bin/sxt reveal a full WebRTC stack (pion/webrtc/v4, pion/turn/v5, pion/ice/v4, coder/websocket, go-qrcode) plus a hardcoded signaling/relay endpoint https://relay.sextant.top/install, giving the binary the shape of a remote-control agent that pairs the installer's host to an author-controlled peer over WebRTC data channels. Adjacent strings 'sk-ant-', 'CLAUDE\_CONFIG\_DIR', 'https://api.anthropic.com/v1/models', 'https://claude.ai/install.sh', and '@google/gemini-cli' show the binary is positioned to read Anthropic API keys and Claude Code / Gemini CLI configuration from the installer and hand them to the remote peer through the established channel. An additional string http://ip-api.com/json/ provides public-IP geolocation of the host for the remote operator. The combination of an opaque metadata-only npm manifest, a bundled native binary embedding a full peer-to-peer control stack, a hardcoded author relay, and embedded references to developer AI-credential material is a backdoor with credential-theft capability against the installer. ## 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-arm64 - **Ecosystem:** npm - **Version:** 0.0.1-rc26 - **License:** SEE LICENSE IN https://github.com/ddos798/claude\_control - **Version published:** 2026-08-03T18:09:01.280Z - **Package first seen:** 2026-08-05T02:15:08.909Z - **Package last seen:** 2026-08-08T22:16:03.397Z - **Known versions:** 31 - **Latest version:** 0.0.1-rc39 - **Appeal under review:** No - **Description:** Sextant (sxt) binary for linux/arm64 - **Maintainers:** twosou123 - **Supported OS:** linux - **Supported CPU:** arm64 - **Artifact files:** 2 - **Artifact unpacked size:** 12,124,558 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]()
