On July 22, all 36 vessels of the Supreme Court of the Los Angeles County, the largest court of first instance in the USA, closed to restore systems after the attack of the Mount Program, which occurred on July 19.
The attack, unclaimed by any known hacker group, impacted the entire network of the Supreme Court of Los Angeles. Both external systems such as MyjuryDuty and the Court website, and internal system management systems were affected. Many court systems are still inaccessible. The closure of vessels for one day was necessary to restore the primary networks. The court is confident that the closure will not extend beyond one day, as the restoration efforts are progressing successfully.
The attack was discovered on July 20, with the court announcing that the hacking began early on the morning of July 19. Upon detecting the attack, LASC promptly shut down all network systems to contain the breach. It is expected that the devices affected will remain offline at least until July 23, until they are fully restored and reconnected to the network.
The court has not found evidence of data compromise on the impacted systems. LASC is working with the Emergency Department of the Governor of California (Caloes), as well as local, state, and federal law enforcement agencies to investigate the incident and assess the ramifications. It has been clarified that this incident is unrelated to the global Windows outage that occurred following an unsuccessful update by Crowdstrike.
The Los Angeles Supreme Court employs more than 4,800 individuals and oversees 36 court buildings in 26 cities within the Los Angeles district, providing services to over 10 million citizens.
