Iowa Attorney General Tom Miller is urging residents who shop at Target to take advantage of free credit monitoring being offered in the wake of a massive date breach.
Miller says Tuesday that Target customers should sign up for the monitoring even if they haven't seen any suspicious account activity. He also recommends that people change passwords and pin numbers and be watchful of their personal information.
Target Corp. initially disclosed that about 40 million credit and debit cards may have been affected by the security lapse between Nov. 27 and Dec. 15. The company later said hackers stole personal information from as many as 70 million customers.
Target is offering a year of free credit monitoring to customers who shopped at its stores.
