American Express says its customers experienced little adverse effects from the Target breach that affected more than 100 million cardholders from a variety of card brands.
However, Amex decided to put in place fraud controls following the breach to protect potentially affected customers, Reuters reported on Jan. 16.

Investigators also acknowledged the complexity and sophistication of the Target malware. Learn more about this disclosure by clicking here.
