Ransomware is known to be one of the biggest threats in cybersecurity, and educational institutions are frequently victims of this type of attack. In fact, we’ve seen a steady stream of them being publicized, particularly as remote learning practices expand in response to COVID-19. So, we’re compiling an ongoing list of 2020 attacks on US schools as an awareness resource for the education community. We will continue to update this page throughout the year as we become aware of additional attacks.
