As Target continues to investigate the circumstances leading up to the data breach from the holiday shopping season, the corporation reveals guest information for up to 70 million customers was stolen -- almost twice as high as the number the chain previously divulged.
Target says that information includes names, telephone numbers, mailing and e-mail addresses of customers who swiped their credit or debit cards sometime between Black Friday and mid-December, November 27 through December 15.
You'll remember, last month Target announced about 40 million credit and debit cards may have been affected by the data breach.
Target says it will try to contact affected customers and guests, by providing tips for protection through e-mail.
It says customers can expect ID protection and credit monitoring services from the retail chain. More details on this plan are expected to be released next week, according to a tweet from the corporation Friday morning.
"We are offering 1 year of free credit monitoring & identity theft protection to ALL guests. Details next week," @target tweeted to those who follow the chain.
Right now, customers can access protection tips through the store's website.
Target continues to investigate the circumstances leading to the data breach, but said Friday that the personal information stolen is not a new breach and was discovered during its ongoing investigation.
New York State Attorney General Eric Schneiderman issued a statement in response to the latest information about the breach.
??The news that Target has discovered a breach involving 70 million customers is deeply troubling," Schneiderman said. "Consumers in New York and around the country expect and deserve companies that protect their personal information when they shop on their websites and in their stores. That is why my office is participating in a national investigation into this breach, why I pressed Target to provide free credit monitoring for the 40 million Target customers identified last month, and why I insist it extends the same service to every new victim.??
Target Corp.'s stock fell in Friday premarket trading.
