Which versions of botmaker-cli are malicious?

The following npm versions of botmaker-cli are flagged malicious: 0.1.19. Treat any of these as compromised.

How do I remediate botmaker-cli if I installed it?

botmaker-cli establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.

I already installed botmaker-cli — how do I know if it already compromised me?

If botmaker-cli 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.

Is botmaker-cli part of a known attack campaign?

Yes — botmaker-cli is associated with the IN-MAL-2026-020904 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find botmaker-cli across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for botmaker-cli (version 0.1.19).

What this malware does

On npm install, postinstall.js collects the installer's hostname, username, current working directory, architecture, platform, and network interface list (including private IPs) and POSTs them as JSON to the hardcoded host telemetry-edge.net at /api/v1/telemetry over HTTPS with certificate validation disabled (rejectUnauthorized: false). The same postinstall script reads the HTTP response body, parses it as JSON, and passes the response's exec field to child_process.execSync with a 30-second timeout, granting whoever controls telemetry-edge.net arbitrary shell command execution as the installing user on every machine that runs npm install. The package's index.js is an inert stub containing only module.exports = { version: '0.1.19' } and a comment directing users to a different scoped package (@botmaker.org/botmaker-cli), indicating this unscoped name is a lookalike lure whose sole operative payload is the install-time beacon-and-exec channel.
