Update: Two other East Tennessee banks are warning their customers to take action to protect their personal information.
Knoxville TVA credit Union says if you shopped at a Target store between November 27th and December 15th, they want you to call them to cancel your card. A representative says they didn't want to take any risks. All customers will have their cards replaced for free.
UT Federal Credit union posted on their website that they are closely monitoring the situation and will be sending all cardholders who may be impacted a letter. They ask anyone with concerns to call them.
At least one East Tennessee bank is taking steps to protect its customers after a massive credit card breach at Target stores across the country.
"Our initial reaction was shock. We've never seen a compromise this large before," said locally owned Citizens National Bank Security and Fraud Risk Management Officer Julie Christensen.
A Target spokesperson said your name, credit or debit card number, and the three-digit security code on the back of cards may be exposed.Target says debit pin numbers were likely not accessed.
Locally owned Citizens National Bank decided to cancel all potentially affected debit and credit cards before they experienced any fraud alerts.
CNB owns branches in Sevier, Jefferson, and Knox Counties.
Their Security and Fraud Risk Management Officer said their card processor alerted them about the Target breach. They searched their system and found close to one-thousand of their customers had shopped at Target during that window.
They made the decision to cancel all of those cards and replace them rather than waiting to see if someone illegally accessed their accounts and then reimbursing them.
"With so much information out there, so many cards compromised, and so close to the holidays, people may be traveling and not looking at their bank statements like we would like for them to do. Things could get by. We think it's best to just go ahead and put a stop to it before it actually starts," said Christensen.
CNB called each customer individually before they cancelled the cards.
10News also spoke with First Tennessee Bank. They advised customers with concerns to your branch.
Both banks recommend checking your statements to look for any incorrect charges and then reporting them.
If your funds are accessed, it's the banks responsibility to reimburse you.
