A key online learning system used by thousands of schools and universities is back after a cyberattack knocked it offline, creating chaos as students tried to study for finals. A cybersecurity threat analyst says a hacking group called ShinyHunters claimed responsibility for breaching Canvas. Instructure, the company behind Canvas, said late Thursday that the system was available for most users. An expert says the hackers posted online that nearly 9,000 schools worldwide were affected, with billions of private messages and other records accessed. Teachers had to find workarounds to help students study for exams and submit final assignments, and some schools pushed back finals.
California Gov. Gavin Newsom says there's no imminent threat to the state from Iran. ABC News says the FBI warned California that Iran had aspired to send drones to the West Coast in retaliation for war. The FBI later released text of the alert, which noted that the information was based on "unverified information." The White House now says, "No such threat from Iran to our homeland exists." Newsom says California and various agencies plan for worst-case scenarios. Police in Los Angeles and San Francisco say they are monitoring world events for any risks.
