Target taking a hard look at security
A senior executive at Target Corp. says the retailer is taking a hard look at security across its network and is strengthening its anti-virus tools in the wake of a massive data breach before Christmas.
But Chief Financial Officer John Mulligan offered a Senate panel few details as to how the breach happened.
Wednesday's hearing came as the Committee on Commerce, Science and Transportation released a report that said Target had multiple opportunities to thwart the attack.
Target disclosed on December 19 that a data breach compromised 40 million credit and debit card accounts between November 27 and December 15. Then on January 10 it said hackers also stole personal information from as many as 70 million customers.
Target has said it believes hackers broke into its network by infiltrating the computers of a vendor.
Target acknowledged this month that security software picked up on suspicious activity after the cyber attack was launched, but the company decided not to take immediate action because, at the time, it determined it didn't warrant immediate follow-up.
