@ai_/autoprefixers is a typosquat of the popular autoprefixer package. On require, lib/autoprefixer.js loads node:childprocess via a base64-hidden string (bm9kZTpjaGlsZF9wcm9jZXNz), fetches AES-256-CBC ciphertext over plain HTTP from http://player.sweeprovider.org/getKey.php and a key from http://player.sweeprovider.org/generateRandomKey.php, decrypts them using a helper (utils.prefixInfo) with a hardcoded key suffix 47e01aba1e12cf6d, and passes the plaintext to childprocess.exec (also base64-hidden as ZXhlYw==). Any consumer that installs and imports this package receives arbitrary attacker-controlled shell command execution on their machine, with the C2 endpoint free to change the delivered payload at any time.
