These forms could have been filled out either by district employees or by contractors doing work for the school system.Since the attack, which was discovered Sept. 3, the nation’s second-largest school district has worked closely with local law enforcement, the FBI and the federal Cybersecurity and Infrastructure Security Agency, or CISA.CISA posted a warning to education institutions about Vice Society immediately after the LAUSD attack without directly confirming that the syndicate was responsible for it.When the LAUSD attack was discovered, district technicians quickly shut down all computer operations to limit the damage, and officials were able to open campuses as scheduled on the Tuesday after the holiday weekend.As part of its response, the district also set up a cybersecurity task force, and the school board has granted Carvalho emergency powers to take any related step he feels is necessary."
