Case 2 – Account Takeover & Unauthorized Orders

Hackers gain access into customer accounts by accessing leaked passwords from previous data breaches. They place large, rapid orders to fake addresses and avoid eCommerce cybersecurity by not using multi-factor authentication.

Case 3 – Chargeback Abuse

Case 4 – Friendly Fraud Scenario

A consumer forgets about a subscription fee and charges back for an “unauthorized transaction.” This “friendly” scam has soared after Christmas, making it even harder for eCommerce sites to maintain trust and cutting into their margins.

Bots try out thousands of stolen cards on your website within a few seconds, and by the time they do it, the alerts have come too late. The blocked attempts mark your merchant account, calling for strong security measures for eCommerce websites, such as CAPTCHA.
