(Kelvin Kuo/Los Angeles Times) The California secretary of state's website appears to have been compromised with advertisements for pornography and cash apps. The breach is part of a nationwide cyberattack pattern; a researcher has tracked at least 38 government agencies across 18 states targeted by similar attacks in recent weeks. The researcher warns bad actors could exploit the vulnerabilities to access citizen information or impersonate government agencies in fraudulent communications, raising urgent questions about government cybersecurity.
