Summary

Hide ▲

Monroe University disclosed a cyberattack breach that left attackers on its network for two weeks, confirming a sustained compromise of a named institution. The unauthorized access window ran from December 9 to December 23, 2024, and it matters because it created the conditions for later data theft. The event was later formalized in breach notifications and shows the intrusion was not a fleeting attempt but an established foothold.
