openmct-couch-pluginnpm
Advisory published Updated
openmct-couch-plugin is a confirmed malicious npm package (MAL-2026-4629) that steals credentials and exfiltrates sensitive data (malicious versions 1.0.0, 1.0.1, 1.0.2). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in openmct-couch-plugin (npm)
What this malware does
On npm install, the package's preinstall script runs node index.js and then curls the output of hostname && whoami to http://8irluql1d21jmq8tr5n5fyoxjopfdd12.oastify.com/nasa/couchrestore/ over plain HTTP. The bundled index.js additionally reads /etc/passwd, captures whoami/id, os.hostname(), os.platform(), os.userInfo().username, the current working directory, and the first 30 entries of process.env, then HTTPS-POSTs the JSON payload to a second hardcoded Burp Collaborator host (3nrgzlqwix6erldow0s0kttsojuai36s.oastify.com). Both endpoints are oastify.com out-of-band-application-security-testing infrastructure used for blind data exfiltration. The package name impersonates NASA's openmct ecosystem (the exfil path /nasa/couchrestore/ reinforces the lure), the package description falsely claims to be an AWS CDK SageMaker workflow, and the README contains the string 'Takeover By l0bo'. Installer harm is unconditional and fires before any user code runs.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for openmct-couch-plugin (3 malicious versions).
If you installed it — respond
openmct-couch-plugin is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If openmct-couch-plugin 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 openmct-couch-plugin-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
