The fetch of the encrypted payload and the decryption/drop are split across two npm packages (cdn-img-fetch stages the PNG, img-to-native decrypts and drops the binary); the shipped code is inert without the companion write and coordinates via a temp-file poll loop with a ~2-minute wait. Steganographic concealment of the payload inside a PNG plus AES encryption with a hardcoded key is deliberate obfuscation to bypass content scanning, and the README's declared file-copy purpose does not match the dropper behavior.
