The Target Data Compromise

(Updated December 23, 2013)

Target announced Thursday, December 19, 2013, that it had suffered a massive data breach that affected at least 40 million of the customers who visited its stores during the height of the holiday shopping season. The company says that it has resolved the problem and that its systems are now secure. To be clear, the individuals responsible for this fraudulent activity did not hack into the MidWestOne Bank database.  For those who may have been affected by the breach, here’s what you need to know:

  1. MidWestOne Bank is closely monitoring the situation and working with our partners to obtain information regarding potentially compromised MidWestOne Bank issued Visa check cards.  We have identified and reissued new Visa check cards for each of the affected MidWestOne Bank cardholder accounts.  These card holders will be notified by postal mail soon, and will receive their new card and PIN within two to three weeks.  Those affected should activate the new card by calling the number on the card.  Then destroy the old card.  Cardholders of breached cards may continue to use those cards until the new one arrives.  The breached cards will be automatically deactivated on January 27, 2013.


  1. MidWestOne Bank check cards are Visa check cards.  Visa has a zero liability policy for fraud protection on unauthorized transactions.  If you discover unauthorized Visa credit or check card charges on your account, and notify us in a timely manner, your liability is $0.  If you see unauthorized postings to your account, notify us as soon as possible.
