The package declares a preinstall hook that runs node callback.js. On npm install, callback.js collects installer-side identifiers — os.hostname(), os.userInfo().username, process.cwd(), the configured npm registry, and CI repo-identifying environment variables (e.g. GITHUB_REPOSITORY) — and issues an HTTP GET to http://75.119.137.232:31337/depconfuse?pkg=... carrying those values as query parameters. The version number 9999.0.0 and the /depconfuse path are consistent with a dependency-confusion reconnaissance beacon designed to identify organizations that internally use a package named rebrandly-domains-digger, so the attacker can target follow-on confusion attacks against their private/internal package namespace. The destination is a hardcoded bare IPv4 on a non-standard port over plain HTTP, with no relation to any legitimate publisher infrastructure.

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.
