Criminal hackers have recently targeted U.S. school districts and will likely continue to escalate their attacks this school year, federal agencies warned Tuesday.
Hackers infected the district’s computer networks with malicious software, locking up files and demanding a ransom payment.
While classes in Los Angeles weren’t canceled, the attack caused a “significant disruption” to the school district and some of its services, the district announced.
Since then, there haven’t been any such high-profile ransomware attacks on energy infrastructure.
Ransomware attacks on schools also run the risk of giving hackers access to children’s personal information, the government warned.
