MAL-2026-17182 Malicious code in app-sca-info-banking (npm)

package.json declares scripts.postinstall: node poc.js, causing poc.js to execute automatically on npm install. poc.js issues DNS (dns.resolve4) and HTTP (http.get) callbacks to unique subdomains under ki6rmdjnq5q8y7v8soxc080fz65ytohd.oastify.com (a Burp Suite Collaborator / OAST host) and writes a marker file under os.tmpdir(). The package's main entry is an empty stub (module.exports = {}); the postinstall payload is the package's only functionality. The DNS/HTTP callbacks to an attacker-controlled OAST domain confirm arbitrary code execution on the installer's host and leak install-event metadata to a third-party 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.

The OpenSSF Package Analysis project identified 'app-sca-info-banking' @ 0.0.24 (npm) as malicious.

It is considered malicious because:

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