The following npm versions of domains-billing-types are flagged malicious: 99.91.1. Treat any of these as compromised.

How do I remediate domains-billing-types if I installed it?

domains-billing-types establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.

I already installed domains-billing-types — how do I know if it already compromised me?

If domains-billing-types was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

What this malware does

[email protected] executes node index.js from its postinstall lifecycle script. On install, index.js reads os.hostname() and os.userInfo().username and embeds them as subdomain labels in a DNS A-record lookup to <hostname>.<username>.aiwm5lowso4vtjynsoije5q4rvxmlf94.oastify.com (Burp Suite Collaborator, an out-of-band interaction server). The DNS resolution transmits the installer's host and user identity to an attacker-controlled OAST endpoint at install time, without consent. The package has anonymous authorship, an empty description ("Billing!"), and no real functionality — the name and shape are consistent with a dependency-confusion probe against an internal package namespace, with the DNS beacon confirming any successful resolution.

The OpenSSF Package Analysis project identified 'domains-billing-types' @ 99.91.1 (npm) as malicious.

It is considered malicious because:

The package communicates with a domain associated with malicious activity.
