🛡️ MAL-2026-12356 — content-publisher-sdks

Malicious code in content-publisher-sdks (npm)

Source: amazon-inspector

package.json declares a preinstall hook that runs index.js on npm install. The script collects host reconnaissance (os.hostname(), os.userInfo(), homedir, DNS server list, current working directory, package.json contents) and reads /etc/passwd and /etc/hosts from the installer's filesystem, then POSTs the aggregated JSON over HTTPS to the hardcoded Burp Collaborator subdomain ie02j5ztgjeb6i7tp467ydwnjep8dy1n.oastify.com. The package name mimics a legitimate SDK category but its only behavior on install is this exfiltration beacon.
