On require/import, index.js issues an HTTPS GET to a hardcoded interactsh OAST subdomain (dapnhid534ch06s9vpm0mbg1httu5gytc.oast.fun) with the installer's os.platform() and os.hostname() as query parameters. The package ships no other functionality; its main module exists solely to fire this out-of-band beacon on load. oast.fun is a public out-of-band interaction collector used to receive callbacks from targets, and the hardcoded subdomain is bound to a specific listener controlled by whoever published the package. This is the canonical dependency-confusion / namesquat probe pattern, in which a package is published to catch internal-name mis-resolutions and report back the host that installed it.
