California Water Service’s billing systems for customers in Bakersfield, Visalia and Chico were not breached through a cyber attack by an Iranian-linked group, according to the corporate spokesperson. … [A]n Iranian-linked hacker group called Handala claimed on Thursday to have breached several water systems in California, specifically in Bakersfield, Visalia and Chico. The group showed screenshots of what it said were residents’ bills from CalWater and claimed to have five gigabytes of data from the alleged breach on its website. … The alleged hack was in retaliation for U.S. strikes that may have damaged two water storage facilities in southern Iran near the strait of Hormuz. [Spokesperson Yvonne] Kingman said Friday that CalWater’s production and distribution systems were not breached and updated SJV Water Monday that the billing system was secure as well.
