How do I remediate cdf-tag-commander-helper if I installed it?

cdf-tag-commander-helper 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 cdf-tag-commander-helper — how do I know if it already compromised me?

What this malware does

The preinstall lifecycle script in [email protected] runs automatically on npm install. It executes whoami and hostname, retrieves the machine's public IP via ifconfig.me, and issues a plain-HTTP GET to a hardcoded Interactsh-style out-of-band callback subdomain (kwphewvexhjbtfduscqybx6q7c862eh0g.oast.fun), passing the three values as query parameters. The README states that the package makes no network requests, which contradicts the shipped code. The behavior is a reconnaissance beacon consistent with dependency-confusion targeting: on install, an attacker learns which internal build hosts and user accounts have resolved this package name.
