There are new details in Target's massive data breach that point to signs that it may be part of a broader worldwide attack.

A new report from Homeland Security indicates that several retailers were potentially targeted.

Investigators say the computer code used by the hackers was partly written in Russian and has been on the black market since last spring.

It went undetected by anti-virus software because the code hid the fact that it was collecting data from magnetic strips on cards.
