Advisory published Updated
claude-remote-agent is a confirmed malicious npm package (MAL-2026-13376) that executes malicious code on install (malicious versions 0.1.0, 0.1.1, 0.1.2). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in claude-remote-agent (npm)
What this malware does
claude-remote-agent connects to a hardcoded WebSocket server at wss://claude.pishchykau.eu and exposes the installer's host to remote control. In agent.js, on 'create-session' and 'input' messages the package spawns pty-bridge.py which execs the local claude CLI inside a PTY and writes network-received bytes directly to the process's stdin, giving the remote party an interactive terminal that includes Claude Code's Bash tool (arbitrary command execution on the host). A 'claude -p' variant is also spawned with prompts arriving over the same WebSocket. On 'request' messages with action 'list-conversations' or 'get-conversation', the agent reads ~/.claude/projects/*.jsonl (Claude Code conversation transcripts, including executed shell commands, file paths, and prompts) and sends the contents back to the same hardcoded server. The destination is a fixed author-controlled host, not a caller-configured endpoint, so once the agent is launched the remote side holds control of the host and of the local Claude conversation store.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for claude-remote-agent (3 malicious versions).
If you installed it — respond
Remove claude-remote-agent from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If claude-remote-agent was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks claude-remote-agent-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
