If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

The README (`# @doctolib-apps/native-personalized-services — Claimed by dphoeniixx`) indicates this package was published as a dependency-confusion claim against an internal scope. Regardless of stated bug-bounty intent, any developer or build system that installs iv-stubborn automatically transmits internal-network identifiers to a third-party server without consent. The combination of namespace-confusion targeting plus install-time beaconing of host data over plaintext HTTP is a supply-chain attack pattern.\n\nAny computer that has this package installed or running should be considered fully compromised.
