The transmission fires automatically on `npm install` with no consent prompt or opt-in. The author self-describes the package as a security-research "canary," but the resulting behavior — squatting a confusable name and silently shipping installer host identifiers to a third-party Cloudflare Workers endpoint — is indistinguishable from a typosquat-and-beacon supply-chain attack, and the installer is not the consenting party.

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.
