As a business owner, you probably maintain hundreds of accounts in your personal life, and have dozens more dedicated to your business.
The frightening reality, though, is that every one of these accounts represents a weakness that fraudsters can exploit.
By stealing your login credentials and breaking into your accounts, scammers can conduct unauthorized transactions in your name. They can even use the information they find in your account to compromise other profiles and users — all without your awareness or permission.
Scared? Don’t be. We’ll give you the rundown on what account takeovers are, how they work, and what you can do to protect yourself against this type of fraud.
An account takeover is a form of identity theft where a third party gains unauthorized access to a user’s online account, and then hijacks the funds or data within the account.
An account takeover typically involves a three-step process. First, a fraudster steals login credentials via phishing, data breaches, or credential stuffing. Then, they access the account using those credentials. Finally, they exploit the account for unauthorized purchases, withdrawals, or to lock out the legitimate user and gather more information for future attacks.

Once in possession of a single working username and password combination, scammers can potentially compromise many other accounts due to password reuse.
Read MoreCardholders, merchants, and financial institutions are all routine targets for account takeover attempts. And, a single account takeover attack can be devastating in all three demographics.
Merchants, for example, may face chargebacks, reputational damage, and higher operational costs. Financial institutions can incur substantial financial liability, loss of customer confidence, and greater security costs.
Cardholders, despite often benefiting from $0 fraud liability guarantees, may still lose control of their personally identifying information (PII). They could also be forced to spend significant time and effort to resolve fraud-related issues that arise.
Read MoreAccount takeovers routinely happen to millions of cardholders and merchants every year in the US. Single attacks, carried out on large and vulnerable accounts, can result in thousands — or even millions — of dollars in losses per incident.
Here, we detail some real-world examples of account takeover attacks, highlighting the fraudsters behind them and illustrating the tangible financial consequences caused by these attacks.
Read MoreAccount takeover attacks are difficult to spot… but they don’t occur without warning. Pay careful attention, and you may be able to notice some telltale signals.
While red flags can differ depending on how fraudsters choose to break in, you can reliably use these warning signs to sniff out when an unauthorized login attempt may be imminent.
Read MoreAt the end of the day, detection alone is not enough. Instead, it’s prevention that counts.
Stopping even a single account takeover from proceeding can save you hundreds of thousands of dollars. That’s not to mention the headaches of resolving the fraud-related fallout that would otherwise occur.
From strong passwords, multi-factor authentication, and multilayered prevention strategies to where to seek professional help, cardholders and merchants can take these actionable steps to keep their accounts secure and out of reach of scammers.
Read MoreOne example of an account takeover may involve a brute force login attempt that targets a cardholder’s bank account. Here, a scammer uses credential stuffing tactics to cycle through thousands of stolen username and password pairs at once. If a combination works, the fraudster can gain unauthorized access to the victim’s account.
Identity theft can be thought of as the precursor to, or enabler of, account takeover fraud. Put another way, all account takeover attempts involve identity theft, but not all identity theft necessarily results in account takeovers.
Some identity thieves may use stolen personally identifying information (PII) to create new accounts themselves, or simply sell the illicitly-obtained data on the dark web.
Account takeovers most often happen when attackers gain access to username and password combinations through phishing tactics or data breaches. Once in possession of these login credentials, fraudsters may use common tactics like credential stuffing to attempt logins.
