Investigators probing the recent holiday season cyberattack are warning retailers about sophisticated malware that potentially affected a large number of stores.
A homeland security official said Thursday that the malware is described in a government report that has been distributed to retailers.
A private firm working on the investigation, iSIGHT Partners, said the hackers behind the malware "displayed innovation and a high degree of skill in orchestrating the various components of the activity."
"It's not necessarily the specific malware components individually that make this new or sophisticated, but it's really the size or scale of this operation at large that makes this unique," said Tiffany Jones, senior vice president at iSIGHT Partners.
