MAL-2026-16477 Malicious code in com.apple.unityplugin.storekit (npm)

The package impersonates an Apple/Unity StoreKit internal namespace (com.apple.unityplugin.storekit) and, on require(), index.js performs an HTTPS GET to a hardcoded Project Discovery Interactsh (oast.fun) subdomain, transmitting the package name, os.platform(), and os.hostname() as query parameters (target: https://dapnhid534ch06s9vpm0mbg1httu5gytc.oast.fun). The behavior is unconditional, undocumented, and fires at module load with no caller opt-in. The name/scope, the author claim of 'Apple, Inc', and the OAST callback destination are the standard dependency-confusion reconnaissance shape: the beacon confirms that an internal build system has resolved the attacker's public package instead of Apple's private one, and leaks the internal hostname of the machine that resolved it.

Any computer that has this package installed or running should be considered fully compromised. 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.
