Advisory
MAL-2026-6968

OpenSSF Malicious Packages via OSV
Summary
Malicious code in rony-testing (npm)
Details
The package's postinstall hook auto-executes index.js on npm install. The script collects the installer's OS username (os.userInfo().username), hostname (os.hostname()), and current working directory, serializes them as JSON, and POSTs the payload to a hardcoded webhook.site endpoint (https://webhook.site/7088d897-5b86-4deb-8d29-5b7a263a49b4). Request errors are silently swallowed to avoid alerting the installer. There is no documented purpose, no consent prompt, and no configuration option — the beacon fires unconditionally on install and transmits installer identity to an attacker-controlled collector.

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.
