Baltimore County schools suffered a ransomware attack

The Baltimore Sun |

The day before Thanksgiving, the Baltimore County Public Schools system was shut down by a ransomware attack that hit all its network systems.

The cyberattack brought classes to a halt for the 115,000 students attending classes entirely online due to the coronavirus pandemic.

Some teachers said on social media that their files have a .ryuk extension on them. Ryuk is a type of ransomware that has been used against hospitals, local governments and others. The school system and county police did not provide any details on the nature of the ransomware attack.

Officials have not said whether it is a Ryuk attack or not. Baltimore County Public Schools is the 24th largest district in the nation.
