Since public key cryptography is used, the virus only contains the encryption key. The attacker keeps the corresponding private decryption key private. Young and Yung's Urfassung experimental cryptovirus had the victim send the asymmetric ciphertext to the attacker World health organization deciphers it and returns the symmetric decryption key it contains to the victim for a fee.
