Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall compliancepolicyserv

What this malware does

[email protected] registers index.js as both scripts.install and main. On npm install and on require, index.js loads lib/core.js, which reads os.userInfo().username, os.hostname(), and process.cwd(), concatenates them with a 'paypal' prefix, a timestamp, and the domain oob.sl4x0.xyz, and issues a dns.resolve4 query against the resulting subdomain, beaconing installer identifiers over DNS to an author-controlled domain. The destination host and the names of the os/dns/process APIs and their methods (userInfo, hostname, cwd, resolve4) are reconstructed at runtime from char-code arrays in lib/b02e30.js and lib/6ad264.js, hiding the exfil endpoint and sensitive API references from static inspection. The package name resembles a compliance-policy service but the shipped code performs no such function; the sole install/import-time effect is the DNS beacon.

Detection & response playbook

Backdoor / remote access
  1. Find it

    Search your lockfiles and build artifacts for compliancepolicyserv (version 9.9.11).

  2. If you installed it — respond

    compliancepolicyserv 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.

  3. Did it already run?

    If compliancepolicyserv 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.

Frequently asked questions

No. compliancepolicyserv on npm has been identified as a malicious package (version 9.9.11 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
