New York -- Following news that luxury giant Neiman Marcus experienced network breaches over the holiday shopping season, similar to those of Target Corp., unidentified sources told Reuters that at least three other attacks on well-known merchants could be revealed in the coming weeks.
According to the report, the sources said the additional breaches involved retailers with outlets in malls, but no more details have been given. Law enforcement has said that they suspect the perpetrators hail from Eastern Europe, and the latest reports suggest all the breaches could have been instigated by the same hackers.
Neiman Marcus said its cyber attack was discovered on Jan. 1 by an outside forensics firm. The retailer first reported the breach on Jan. 10, just three weeks after Target revealed that some 40 million payment card numbers had been stolen in its cyber attack. On Friday, Target said the data breach was worse than initially thought.
On Monday, Reuters reported that Democratic members of the Financial Services Committee of the U.S. House of Representatives are calling for the panel to investigate the Target breach.
