Summary
Malicious code in afterpay-sdk-example-server (npm)
Details

package.json declares a preinstall hook ("preinstall": "node index.js") that runs automatically on npm install. index.js requires os/fs/https, then collects host identifiers and installer-side files — __dirname, os.homedir(), os.hostname(), os.userInfo(), DNS servers, the full contents of /etc/passwd and /etc/hosts, and the package.json — and POSTs them over HTTPS to xqrangwae3pk5bd12xbr6t8q9hfc32rr.oastify.com (a Burp Collaborator OAST subdomain). The package name 'afterpay-sdk-example-server' impersonates an internal Afterpay SDK example, consistent with a dependency-confusion payload targeting Afterpay's internal build systems. Whether published as research or attack, any installer running npm install leaks system account data and host fingerprints to an attacker-controlled out-of-band collection endpoint.

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.

Source: ossf-package-analysis (555a159aa3b74ea73f8574c05e14aa536948cbe56b0420bcdcc0daa2a911ae2c)

The OpenSSF Package Analysis project identified 'afterpay-sdk-example-server' @ 20.0.0 (npm) as malicious.

It is considered malicious because:

  • The package communicates with a domain associated with malicious activity.
