Salon and beauty supply retailer Sally Beauty Supply is the latest U.S. company to suffer a data breach, confirming it noticed "unusual activity" on its network in late February.
Sally Beauty has 2,700 locations throughout the United States, and is now working with police and federal authorities to investigate the breach. The company promised to continue monitoring its network while improving security as Verizon Enterprise Solutions lends an outside hand.
Security specialists found a fresh batch of 282,000 stolen debit and credit cards on an underground hacker forum available for sale - and some reportedly were used at Sally Beauty locations.
Federal authorities are busy trying to help numerous major retailers deal with cyberattacks likely launched from criminal groups overseas. The Target breach in late 2013 was the highest-profile retailer breach, but companies such as Neiman Marcus and Michaels also have suffered data breaches.
