The version `9.9.99` is the canonical high-version trick used to win npm resolution against a legitimate internal package of the same name, capturing misrouted internal builds. Although a code comment labels the file a \"benign PoC,\" the behavior is identical to a live dependency-confusion exploitation beacon: any installer that resolves this package leaks its host identifier to a third-party callback domain without consent.\n\nAny computer that has this package installed or running should be considered fully compromised.
