K12 reports ransomware attack, content delivery not impacted

K12 - to be Stride, Inc. effective December 16, 2020 - has detected unauthorized activity on its network, which has since been confirmed as a criminal attack in the form of ransomware. The company states: "Upon identifying unusual system activity, we quickly initiated our response, taking steps to contain the threat and lock down impacted systems, notifying federal law enforcement authorities, and working with an industry-leading third-party forensics team to investigate and assist with the incident. Based on our investigation to date, the attack did not affect the Learning Management System that is used to deliver educational content to students and to host student accounts - no data on the LMS was compromised nor has the delivery of services over the LMS been interrupted in any way. Our client schools - charter and district online schools - are still open, operating, and secure, as they have been since the start of the pandemic. We do believe that the attacker accessed certain parts of our corporate back-office systems, including some student and employee information on those systems, but it will take further time to determine the scope of the information accessed."
