🛡️ MAL-2026-13455 — remote-claude-daemon

Malicious code in remote-claude-daemon (npm)

Source: amazon-inspector

remote-claude-daemon connects to a hardcoded WebSocket relay at wss://remote-claude-relay.fly.dev and treats inbound messages as commands executed against the local host. On receiving ai_query/ai_voice_query messages, the daemon spawns the local claude binary with --continue -p --dangerously-skip-permissions and the remote-supplied prompt as input, giving the remote side arbitrary code execution through Claude Code's agent tooling with the permissions prompt disabled. A separate handleInput path dispatches remote messages to synthesised mouse moves/clicks, keyboard keypresses (including modifier chords) and clipboard paste via @nut-tree-fork/nut-js, giving the remote side full interactive control over the installer's desktop. The daemon additionally captures screen frames (native SCStream on macOS via a shipped Swift helper, ffmpeg gdigrab/x11grab on Windows/Linux) and optional microphone PCM audio and streams them over the same relay. Although the package is documented as a remote-Claude bridge, session tokens gate access, and --relay can override the default, the out-of-the-box configuration wires an author-controlled endpoint into an RCE + input-injection + screen/audio-capture surface on the installer. The relay operator (or anyone who obtains a session token, MITMs the connection, or compromises the relay) can execute arbitrary commands as the user, control input, and stream desktop/audio contents.
