hexo-shoka-swipernpm

The package ships a binding.gyp whose sources field uses GYP command-expansion syntax (<!(...)) at line 6. npm implicitly runs node-gyp rebuild whenever a binding.gyp is present (even with no declared install/postinstall script), and GYP evaluates <!(...) as a shell invocation during the configure step. This means simply running npm install hexo-shoka-swiper causes the embedded shell command to execute on the installer's machine. The package's nominal purpose is a Hexo theme Swiper integration — a pure JavaScript front-end concern with no legitimate need to build a native addon or to evaluate shell at install. The binding.gyp here functions as a lifecycle-hook substitute for arbitrary install-time code execution rather than as a real native-build description.

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.
