Early this morning, the chief of staff for Baltimore County Public School systems, Mychael Dickerson, tweeted that all schools would be closed today due to network issues. As it turns out, it was ransomware affecting the network, as he later tweeted the following:
Here is the latest update:
Baltimore County Public Schools can now confirm we were the victim of a Ransomeware cyber attack. This caused systemic interruption to our network information systems. Our BCPS technology team is working to address the situation. Updates as available.

Local news station WBAL-TV 11 News reports that they “received reports of teachers who lost lesson plans and other data.” This is only the early stages of the attack, so it is unknown what other data could have been lost, but this could be bad. The ransomware affected the BCPS offices as well, so there is likely more data loss that we do not yet know about.
In May of 2019, the city of Baltimore experienced a ransomware attack that impacted many systems throughout the city’s network. This new attack against the school system may be by the same attacker, but researchers have not yet determined if this is indeed the case. We will likely find out more about the attack in the coming days, so stay tuned.
