What is MAL-2026-13376?

MAL-2026-13376 is a malicious package in claude-remote-agent, published on 5 Aug 2026.

Official description

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.
