A ransomware attack prompted Des Moines Area Community College to take its entire campus system offline for two weeks, according to a statement provided by DMACC officials to the Business Record today.

While in-person classes are back in session, online-only classes are postponed today as the college continues to work on restoring the DMACC network. The college will resume online-only classes the day after the network is fully restored, DMACC said in a statement.  

“With the support of the third-party cybersecurity forensic firm, we have since determined that this was a ransomware attack,” DMACC spokesperson Susan Metheny said in an emailed statement to the Business Record. “Out of an abundance of caution, we proactively took our systems offline to contain the threat. Our investigation is ongoing, but, at this time, we cannot say for certain what information or data, if any, has been impacted as a result. Our primary focus remains on a safe and efficient remediation process and the restoration of our systems.”

DMACC has notified the Department of Education of the ongoing investigation, Metheny wrote. The college’s IT department and outside cybersecurity analysts were joined last week by the FBI in the investigation, which was first launched June 2 when the cybersecurity threat was detected. President Rob Denson did not immediately respond to a request for comment.
