California-based Santa Clara Family Health Plan has announced that 276,993 members had their sensitive data potentially compromised in a Clop ransomware attack that involved the exploitation of a flaw in the Fortra GoAnywhere Managed File Transfer system, which the insurer has been using to exchange files with NationsBenefits, according to Government Technology. Information that may have been exposed includes members' names, birthdates, contact details, IDs, and Medi-Cal credentials, said Santa Clara Family Health Plan, which has also encouraged increased member vigilance on identity theft and financial fraud. Such a disclosure comes after the state's City of Oakland had hundreds of gigabytes of employee data stolen and leaked on the dark web. "The Bay Area is still reeling from the recent ransomware attack on the City of Oakland, and it seems almost a weekly occurrence that an organization is hacked and extorted for ransom by cybercriminals," said UC Berkeley Center for Long-Term Cybersecurity Public Interest Cybersecurity Program Director Sarah Powazek.
