What is Account Takeover Fraud?
Account takeover fraud occurs when a criminal gains unauthorized access to a legitimate user account and exploits that access for fraudulent purposes. Criminals achieve this by impersonating the account holder in person at a branch, over the phone, via email, or through online banking portals or mobile apps.

Having gained access to the account, bad actors can attempt to carry out various types of nefarious activity while pretending to be the real account holder, with often costly and harmful consequences.
For example, criminals can:
- Change the customer’s contact information to prevent the financial institution from being able to contact the legitimate account holder
- Make unauthorized transactions
- Access the account’s overdraft limits or credit lines
- Order checks or replacement debit or credit cards
- Harvest sensitive user data and account information to commit other forms of fraud
It is essential for financial institutions seeking to improve their defenses to understand account takeover fraud, why it is so damaging and what is driving it.
