log-rotate-testmetest@1.0.1

Summary

The package ships a binding.gyp whose sources field uses GYP command-expansion (<!(env node index.js...)) with no native source files, causing npm's implicit node-gyp rebuild to execute index.js at install time. index.js is a Caesar+10 (ROT) obfuscated eval blob that, once decoded, AES-128-GCM-decrypts a hardcoded hex ciphertext and the sibling data.bin, brotli-decompresses the result, writes it to a mkdtemp'd temporary file, and spawns it under Bun (Bun.spawn([execPath,'run',tmp]) / spawn(getBunPath(),['run',tmp])). package.json declares bun as a runtime dependency, deliberately routing execution through an alternate runtime rather than Node. The executed payload is fully opaque and attacker-controlled. The combination of a no-source binding.gyp used solely as a lifecycle trigger, multi-layer obfuscation (ROT + AES-GCM + brotli), and alternate-runtime dispatch has no legitimate native-build justification.
