Marymount Manhattan College experienced a network disruption on Nov. 12, 2021, which was the result of a cyberattack. This page provides additional details about the incident.

The MMC IT team, working in concert with cybersecurity experts, immediately determined that the network had been accessed without authorization. Upon making this determination MMC:

  • promptly began working with external cyber and legal experts to investigate and respond to the unauthorized access;
  • notified and coordinated with all relevant agencies as necessary, including law enforcement;
  • strengthened the College’s IT network, including deploying state-of-the-art security software on all MMC devices;
  • took every avenue available to minimize the exposure of any sensitive data that was potentially compromised and worked to successfully recover the data.

A thorough and extensive data review was then conducted and has recently concluded. From that review, it was unfortunately confirmed that personally identifiable information of some members of the MMC community was accessed and acquired during the incident. Those whose information was involved are being notified separately via a mailed letter, which details steps they can take to help protect their personal information.

If your data was involved and the college has address information for you, you will receive a direct notification via the U.S. Post Office detailing the specific information that was involved as well as the steps you can take to further protect yourself. Note that the return address on the letter will have a California PO Box because that is the location of the company the college has partnered with to offer complimentary identity protection services. Those letters were mailed Wednesday, Aug. 3, 2022.

MMC deeply regrets any worry or inconvenience that this causes members of our community.
