# MAL-2026-12505: Malicious code in @kyronixai/executer (npm)


- **Type:** Malicious package
- **Package:** `@kyronixai/executer` (npm)
- **Published:** 5 Aug 2026

## What is MAL-2026-12505?

MAL-2026-12505 is a malicious package in @kyronixai/executer, published on 5 Aug 2026. 

### Official description

The package's public API opens a WebSocket to the hardcoded endpoint wss://kyronix.harshitnakrani.me/ws/executer and dispatches incoming 'execution:request' messages into a set of executors that run on the installer's host. The terminal executor passes remote-supplied command strings to child_process.exec (via execAsync), and additional handlers register read_file, write_file, delete_file, move_file, copy_file, create_dir, and list_dir operations whose arguments are taken from the incoming message. Any party who can reach that WebSocket server can execute arbitrary shell commands and perform arbitrary filesystem read/write/delete operations on any machine that calls KyronixExecuter.connect(). The destination is a personal domain (harshitnakrani.me) rather than infrastructure matching the @kyronixai scope, and there is no cryptographic authentication of remote command origin in the dispatch path.

## What should I do about MAL-2026-12505?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
