Mount Royal University ransomware attack
A ransomware attack hit Mount Royal University in Calgary in mid June 2026, disrupting its website, portals, campus internet and phones. The attacker copied data from specific folders on a shared staff and student H drive, then deleted the H drive and a corporate J drive. MRU says there is no evidence that J drive data was copied. The university has restored many services, including Infosilem by 2026-08-10 and the full H drive by 2026-08-13, but its investigation, remaining website and portal functions, and full recovery of J drive data remain open. CMD Organization claimed the attack, but MRU and government agencies have not attributed it to the group.

Who is behind it
CMD Organization claimed the attack, but MRU and government agencies have not attributed it to the group.
Impact
The attack disrupted MRU's website, MyMRU portal, campus Wi-Fi, phones and internal services for weeks. The website, phones, secure Wi-Fi and much of MyMRU were restored by late July. More services returned through 2026-08-10, including visitor Wi-Fi, Argos reporting and Infosilem. By 2026-08-13 MRU said the H drive itself had been fully restored and the old MROpen Wi-Fi network was decommissioned in favor of MRSecure and MRVisitor. By late August, network printers, scan-to-email and remote VPN access to several systems were working again, and eduroam was available to visitors, though Webfiles still showed a blank folder list and J drive data recovery was unfinished. As of Sept. 1, MRU says remaining MyMRU portal functions, remaining website functions and J drive data recovery are still in progress.
What to do
People notified that their H drive folder was affected should follow MRU's notice, monitor financial accounts and watch for unexpected messages asking for personal information. They can ask MRU for a list of filenames stored in the affected folder. Eligible current and former employees should enroll in the free credit monitoring service by 2026-11-30. Anyone who suspects identity fraud linked to the incident should report it to MRU.
