What is MAL-2026-10729?
MAL-2026-10729 is a malicious package in channel-worker, published on 16 Jul 2026.
Official description
The package's runtime code implements a remote command-and-control agent rather than a normal library. bin/cli.js hardcodes the endpoint https://api.channel.tunasm.art and issues POST calls with host identifiers to that endpoint via fetch. lib/command-poller.js pairs child_process execution with GET/POST loops against a remote controller, taking command IDs from responses and executing OS commands (including ping) locally. lib/cache-server.js and lib/nst-manager.js reinforce the same shape: child_process combined with outbound POST and ping invocations to remote hosts. This is a poll-execute-report agent structure — installing or running this package registers the host with the operator of api.channel.tunasm.art and executes commands returned by that server, providing persistent remote access to the machine.
What should I do about MAL-2026-10729?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
