Account Takeover Attacks Are an Enormous Vulnerability for Which Many Merchants Are Unprepared
By FF Newsroom · 20 May 2020

Riskified, the payments and fraud-prevention solutions provider, today released a survey on the effect of Account Takeover (ATO) attacks on eCommerce merchants and customers. ATOs happen when a bad actor gains access to a legitimate customer’s eCommerce store account and uses that account for fraud. The survey shows that ATO attacks have a huge negative impact on customers and merchants, damaging brand reputation and hurting merchants’ bottom lines. Despite that, many merchants lack security measures, and more than one in three (35%) of merchants report that at least 10% of their accounts have been taken over in the last 12 months.
Both merchants and customers value secure store accounts. Customers cite their convenience and the opportunity to earn rewards as notable benefits. Merchants report that account holders shop more often and spend more per purchase than other customers.
But accounts can also increase risk if they are not properly secured. Sixty-six percent of merchants and 69% of customers say they are concerned about their accounts getting hacked. Purchases made using compromised store accounts are hard for merchants to detect, because they look like they are made by legitimate returning customers. ATOs are also very costly for merchants. When fraudsters use compromised accounts to make fraudulent purchases, not only does the merchant lose the revenue and the value of the goods sold, but it also often suffers serious damage to its brand reputation and diminished customer lifetime value.
65% of customers say they would likely stop buying from a merchant if their account was compromised. More than half (54%) of customers say they would delete their account, 39% would go to a competitor, and 30% say they would tell their friends to stop shopping with the merchant.
Preventing ATOs presents unique challenges:
Because ATOs require only a login and stolen password, merchants have less data with which to evaluate the action, making detection and prevention difficult. Many merchants are failing to do so:
- More than a quarter of merchants (27%) admit that they do not have measures in place to prevent ATOs.
- 24% of merchants can’t identify an ATO during a purchase
- 14% of merchants say they are not even aware that an ATO has occurred unless a customer contacts them.
- Only 7.5% of customers learn their accounts were compromised from the merchant. The vast majority spot changes to their accounts or learn of unauthorized purchases.
- 83% of customers say they have accounts on individual sites for shopping.
- 75% do most or all of their online shopping with merchants where they have accounts.
- 42% said they shop more frequently when they have an account.
- More than 67% of the merchants surveyed say at least half of their orders come from customers with accounts.
- 58% of merchants report that account holders spend more per purchase than customers who use guest checkout.
- 61% say that account holders purchase more frequently than customers who use guest checkout.
