npm uninstall @inpeek/odata-angular

What this malware does

@inpeek/[email protected] is a dependency-confusion squat on the private @inpeek scope, published to the public npm registry at an inflated version (99.99.102) to win resolution against an internal package of the same name. package.json declares scripts.postinstall as 'node./ping.js'; ping.js issues an HTTPS GET to the third-party collector https://db1b65hgnouukn3qov9gta83zgkdao9dy.oast.me/ carrying os.hostname(), os.platform(), process.version, and the package name as query parameters. index.js throws on require, so the package has no legitimate library function; the only install-time effect is the beacon to the external OAST domain. Any CI job or developer workstation whose resolver picks @inpeek/* from the public registry executes the beacon on npm install and leaks host identifiers to an attacker-controlled destination, regardless of a 'bug bounty research' framing in the description.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

Detection & response playbook

Backdoor / remote access
  1. Find it

    Search your lockfiles and build artifacts for @inpeek/odata-angular (4 malicious versions).

  2. If you installed it — respond

    @inpeek/odata-angular 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 @inpeek/odata-angular 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. @inpeek/odata-angular on npm has been identified as a malicious package (versions 99.99.99, 99.99.100, 99.99.101, 99.99.102 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
