Target data leak may have come through contractor
NEW YORK – The hackers who stole millions of customers’ credit and debit card numbers from Target may have used a Pittsburgh-area heating and refrigeration business as the back door to get in.
If that was, in fact, how they pulled it off – and investigators appear to be looking at that theory – it illustrates just how vulnerable big corporations have become as they expand and connect their computer networks to other companies to increase convenience and productivity.
Fazio Mechanical Services Inc., a contractor that does business with Target, said in a statement Thursday that it was the victim of a “sophisticated cyberattack operation,” just as Target was. It said it is cooperating with the Secret Service and Target to figure out what happened.
The statement came days after Internet security bloggers identified the Sharpsburg, Pa., company as the third-party vendor through which hackers penetrated Target’s computer systems.
Target has said it believes hackers broke into its vast network by first infiltrating the computers of one of its vendors. Then the hackers installed malicious software in Target’s checkout system for its estimated 1,800 U.S. stores.
Experts believe the thieves gained access during the busy holiday season to about 40 million credit and debit card numbers and the personal information – including names, email addresses, phone numbers and home addresses – of as many as 70 million customers.
Cybersecurity analysts had speculated that Fazio may have remotely monitored heating, cooling and refrigeration systems for Target, which could have provided a possible entry point for the hackers. But Fazio denied that, saying it uses its electronic connection with Target to submit bills and contract proposals.
