What happens to the ransomware after it’s used?

After a ransomware attack, the attacker will typically encrypt the victim’s files and demand a ransom be paid in order to decrypt the files. The victim may or may not have a backup of their files, which will dictate whether or not they will be able to recover from the attack. If the victim does not have a backup, they will likely have to pay the ransom in order to get their files back. After the ransom is paid, the attacker will typically provide the victim with a decryption key that will allow them to decrypt their files. In some cases, the attacker may not provide the key even after the ransom is paid, which can leave the victim’s files permanently encrypted. There have also been cases where the decryption key provided by the attacker does not work, or only partially decrypts the files. In these cases, the victim may be left with permanently encrypted files and no way to recover them. There have been instances where attackers have made ransomware that specifically targets critical infrastructure, such as hospitals. In these cases, the attackers may not release the decryption key even if the ransom is paid, as they may be intending to cause as much damage as possible. There have also been instances of so-called “ransomware as a service”, where attackers will develop and distribute ransomware to others who can then use it to attack victims. In these cases, the original attacker may or may not have any involvement in the actual attack, and may not even know who the victims are..See page
