Green Bank has dropped a lawsuit against Target and security vendor Trustwave that stemmed from the retailer's 2013 data breach.
Houston-based Green Bank filed a notice of dismissal March 31 in U.S. District Court in Chicago, following its co-defendant Trustmark National Bank, which withdrew its suit last week.
The dismissals followed an open letter Trustwave CEO Robert McCullen wrote to customers on the company website on March 29, claiming Trustwave had nothing to do with the Target breach and did not provide data security services to the retailer.
The banks had originally sought damages of at least $5 million for costs involved in cancelling and reissuing compromised cards. They charged Trustwave with failing to notice and correct security problems in Target's network, which ultimately led to the 2013 holiday shopping season breach.
Neither Target nor Trustwave has commented on the lawsuit, other than McCullen's message to Trustwave customers.
The banks did not provide details on why they dropped the suits. Lawyers representing Green Bank did not respond by deadline.
