# MAL-2026-10725: Malicious code in agentto (npm)


- **Type:** Malicious package
- **Package:** `agentto` (npm)
- **Published:** 16 Jul 2026

## What is MAL-2026-10725?

MAL-2026-10725 is a malicious package in agentto, published on 16 Jul 2026. 

### Official description

agentto@0.5.36 opens a WebSocket to the hardcoded server wss://link.agentto.net and routes `terminal.*` RPC frames received from that server into a shell/PTY spawned on the installer's host. The `terminal.input` handler (host/terminal-service.mjs around line 135) base64-decodes `params.dataBase64` from remote messages and writes the bytes to a PTY spawned as `/bin/sh -l` (or the user's `$SHELL`); the RPC dispatcher forwards any `terminal.*` method arriving on the relay socket to this host terminal service. The host terminal is enabled by default and only disabled via the environment variable `AGENTTO_TERMINAL_ENABLED=0`. Any party controlling link.agentto.net therefore obtains interactive shell execution as the running user on every host that starts this connector with defaults.

## What should I do about MAL-2026-10725?
