The package ships a binding.gyp whose target has type "none" and no C/C++ source files; its only purpose is a GYP <!(...) command-expansion that runs node index.js during the automatic node-gyp rebuild triggered by npm install. index.js is multi-layer obfuscated: a char-code array is Caesar-decoded (shift 21) and passed to eval; the decoded body reads the bundled lib_native.dat (~312 KB, high-entropy, sha256 e1ab1e330d3db532d511d4af4386ab2d2c6245ca807410f51c1211ae48814d73), brotli-decompresses and AES-128-GCM-decrypts it with hardcoded key/IV/AAD, writes the plaintext to a mkdtempSync('.b-')/index.js temp path, and spawns the Bun runtime (Bun.spawn, or getBunPath() via child_process.spawn) to execute the decrypted payload. Executing under Bun bypasses Node-only analysis. The contents of the executed payload are not inspectable from the shipped artifact.
