Fairfax County Public Schools (FCPS) was recently hit by ransomware. The Virginia school division is the 10th largest school division in the US and has a budget of $3.1 billion. The exact date of the attack is not yet known but the school division says it is working with the FBI to determine what ransomware gang is behind the attack. The attack on FCPS was already claimed by the Maze ransomware operators who have already leaked 2% (an archive of roughly 100MB) of what they claim to be data stolen from their servers.
