On August 5, a file containing member information was inadvertently made available through Missouri Credit Union's website.
The file contained a list of members' names, addresses, Social Security numbers, account numbers, and MCU teller/call-in passwords. According to MCU, the file was immediately removed and only ten visits were made to the file's location during the time it was accessible.
"We just were informed about the breach two weeks later by a letter in the mail," said MCU customer Terry Donner in an e-mail to KRCG. "Very poor customer service."
Missouri Credit Union began notifying all members by mail on August 16. As a precaution, MCU arranged to have AllClear ID protect the identity of the members whose information was in the file for one year.
"On behalf of myself and everyone at MCU, I apologize to all members affected by this incident," said President Hal James. "Please be assured that we are working to enhance our security measures to prevent something like this from happening in the future."
MCU has set up a call center for concerned members who have questions about what occurred and steps they can take to protect themselves. The call center is open Monday-Friday from 8 a.m. to 8 p.m., and the toll-free number is (877) 437-4006.
