MAL-2026-4629 Malicious code in openmct-couch-plugin (npm)

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.
