The Baltimore County Public Schools system today canceled classed and closed offices after it was hit with a ransomware attack that led to a systemic shutdown of the school system’s network information systems.

Ransomware attacks typically encrypt files and lock them up so users can’t access them. The attackers then demand a ransom amount, typically in Bitcoin digital currency, in exchange for the decryption keys to unlock the files.
