Summary
Malicious code in octopus-action (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (6968c2a12f60b671ee163f42c9da14ed51d9b0b29486b4a7d1bf5014b4c637f2)

The package declares a preinstall lifecycle script (node index.js) that runs automatically on npm install. index.js collects the installer's hostname, OS username, home directory, configured DNS servers, package metadata, and the contents of /etc/passwd and /etc/hosts, then POSTs the payload over HTTPS to dfwvktnc563cparn1p88c8051w7ovej3.oastify.com, a Burp Collaborator out-of-band host controlled by a third party. Installing the package causes installer host identifiers and system files to be exfiltrated to that endpoint.
