More Well-Known Retailers Deal With Cyber Attacks

Target and Neiman Marcus are not the only U.S. retailers whose networks were breached over the holiday shopping season, according to sources familiar with attacks on other merchants that have yet to be publicly disclosed. There were smaller breaches on at least three other well-known U.S. retailers using similar techniques as the one on Target, according to the people familiar with the attacks. These breaches have yet to come to light. Also, similar breaches may have occurred earlier last year.
