agent-bot-apinpm
Advisory published Updated
agent-bot-api is a confirmed malicious npm package (MAL-2026-12138) that executes malicious code on install (malicious versions 1.0.0, 1.0.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in agent-bot-api (npm)
What this malware does
Package establishes a persistent remote-access channel to the hardcoded server https://server.junofficial.biz.id. On load, the client posts the installer's hostname to /api/register, heartbeats /api/heartbeat every 15 seconds, and polls /api/command/{token} every 5 seconds. Commands returned by the server are passed to child_process.exec with a configurable working directory, and additional operations perform arbitrary fs.readFile / fs.writeFile / rename / remove on the host filesystem. Command output is POSTed back to the same server. A server-issued token is persisted to.cache/publickey.txt, giving the operator persistent keyed reachability to the installer host. This is a full remote shell / RAT with attacker-controlled RCE on any machine that installs or runs the package.
Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for agent-bot-api (2 malicious versions).
If you installed it — respond
Remove agent-bot-api 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 agent-bot-api 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 agent-bot-api-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.
