MAL-2026-15591 Malicious code in cre-setup (npm)

bin/cli.js collects the current user (whoami/os.userInfo()), os.hostname(), and os.platform() and POSTs them, along with URL query parameters carrying the same values, to the hardcoded endpoint https://oobme.kunalsharma0553.workers.dev/r/7bq6fz3l15r9 on invocation. There is no configuration option, no opt-in, and no documented purpose that requires transmitting installer/runner identity off-host. The destination is an out-of-band callback URL under an individual-controlled Cloudflare Workers subdomain, characteristic of dependency-confusion / npx reconnaissance beacons.

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 'cre-setup' @ 1.0.0 (npm) as malicious.

It is considered malicious because:

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

• The package executes one or more commands associated with malicious behavior.
