What is MAL-2026-14218?

MAL-2026-14218 is a malicious package in mapkit-loader, published on 19 Aug 2026.

Official description

Unscoped npm package 'mapkit-loader' impersonates the scoped '@apple/mapkit-loader' to intercept mistyped npx mapkit-loader invocations. The package.json self-describes as a 'PoC' targeting that confusion. On npm install, the postinstall lifecycle script (postinstall.js) unconditionally issues an HTTPS POST to a hardcoded third-party endpoint at npx-monitor-76056.azurewebsites.net/api/pingback carrying a persistent UUID, package version, trigger source ('npm-postinstall'), and timestamp. The UUID is written to ~/.cache/.mapkit-loader-id so subsequent executions (including the bin entry) can be correlated back to the same host. No credential or filesystem exfiltration is present, but the combination of name-confusion targeting an official Apple scope plus install-time beaconing to an author-controlled endpoint is a supply-chain typosquat with an operational tracking channel.
