“We’re asking everyone who shopped at a Target location since Black Friday to monitor their credit card accounts and contact their banking establishments to see if there is any suspicious activity,” Molly Snyder, a Target spokesperson said. “Anyone with a Target Red Card or a card from another bank should remain vigilant and keep checking their accounts for fraudulent activity.”

Target is working with authorities to learn more about the incident and is currently alerting shoppers with email addresses to take caution. I got my email alert Thursday night!

Target said it had immediately notified law enforcement agencies as soon as it discovered the breach, and that it planned to hire a third-party digital forensics firm to investigate the breach and recommend information security improvements.

Target has set up a dedicated call center and is addressing frequently asked questions related to the breach on its website. If you shopped at a Target store in this designated time frame, you can call 866-852-8680.

“We are also answering questions on social media and trying to reach people anywhere they are engaged with the latest information,” Snyder said.

According to password security firm LastPass, Target shoppers should not only monitor bank and various online accounts for suspicious activity, including email and social sites such as Facebook and Twitter, but also change their debit card PINs.
