Vendor Confirms Link to Target Data Probe

By  | 

PITTSBURGH (AP) - A Pittsburgh-area heating and refrigeration contractor says it was the victim of a "sophisticated cyber-attack operation" that is being investigated by the Secret Service and possibly linked to the data breach that enabled hackers to access millions of credit card numbers belonging to Target store customers.

Fazio Mechanical Services Inc., of Sharpsburg, issued the statement after Internet security bloggers identified it as the third-party vendor through which hackers accessed Target's customer information.

Target had previously told reporters the store believed hackers accessed 40 million of its customers' card numbers through a vendor's system.

The Secret Service has confirmed an investigation into Fazio's business, but isn't providing details.

Federal prosecutors and Target officials haven't responded to requests for comment.
