A ransomware outfit calling itself Vice Society has dumped nearly 300,000 files belonging to the Los Angeles Unified School District as punishment for rebuffing demands it pay the group a hefty fee to recover data stolen during a recent cyber intrusion.

Ransomware operators breach targets’ networks, encrypt all their data, and then charge victims a ransom for the decryption key. More recently, the groups have moved to a double extortion model, in which they also publish the data on the dark web unless victims pay a ransom to keep it private. Already this year, 27 school districts with 1,735 schools among them have been hacked in ransomware incidents, Brett Callow, a threat analyst with security firm Emsisoft, said.
