On npm install, this package's postinstall script collects host identifiers (os.hostname(), os.userInfo(), current working directory, and external IPv4 address) and POSTs them to a hardcoded subdomain under oast.fun (lpzlajzjfkpfeefuzxbv6n5nob7bpuh6e.oast.fun, path /receive-data). oast.fun is an Interactsh out-of-band collector commonly used for dependency-confusion reconnaissance. The package metadata is consistent with a dependency-confusion squat: name prefixed with 'testing-', version 99.9.9 (unrealistically high to win registry resolution against an internal package of the same short name), empty author/description/keywords. Installing this package causes the installer's machine identifiers and network address to be sent to a third-party collector controlled by whoever registered the OAST subdomain.
