SAN FRANCISCO -- The malware at the center of Target's recent data breach affecting millions of customers was partly written in Russian, according to a report issued Thursday by U.S. government authorities and cyber security researchers.

The report, which was only distributed to organizations that are involved or may have been attacked, describes a sophisticated cyber attack operation authorities are calling Kaptoxa, a Russian word that comes from a piece of code in the malware.

Some parts of the malware code were written in Russian and BlackPOS, the malware from which this latest malware derived, was originally developed by a Russian cyber crime master, according to Tiffany Jones, a spokeswoman for iSIGHT Partners.

iSIGHT, an online security firm, helped research and produce the report, along with the Department of Homeland Security, the U.S. Secret Service and the Financial Services Information Sharing and Analysis Center. The firm posted a summary of the report on its website Thursday.
