When a user account is compromised, it can be used for a myriad of crimes. For instance, it can be used to send out spam or phishing messages. Banking accounts when compromised can cause financial losses. Attackers can access saved payment details (such as credit card details) and passwords for further financial crimes. They can also redeem reward points. In addition, they can use compromised accounts for money laundering, money muling, and a host of other sinister crimes.
