A system that thousands of schools and universities use was offline on Thursday during a cyberattack, creating chaos as students tried to study for finals and underscoring education's dependence on technology. The hacking group named ShinyHunters claimed responsibility for the breach at Canvas, said Luke Connolly, a threat analyst at the cybersecurity firm Emisoft. Instructure, the company behind Canvas, didn't immediately respond to a request for comment or questions about whether the system was taken down as a precaution or because the hackers knocked it offline. Canvas is used to manage grades, course notes, assignments, lecture videos and more. The hacking group posted online that nearly 9,000 schools worldwide were affected, with billions of private messages and other records accessed, Connolly said. Students quickly took to social media to ask if others were unable to access Canvas, with many panicking that they could no longer view course materials housed within the platform
Pro-Iranian hackers are targeting sites in the Middle East and starting to stretch into the United States during the war, raising the risk of American defense contractors, power stations and water plants being swept into a wave of digital chaos that could expand if Tehran's allies join the fray.

Since the war began February 28, they also have tried to penetrate cameras in Middle Eastern countries to improve Iran's missile targeting.

Iran has invested heavily in its offensive cyber capabilities while cultivating ties to hacking groups. In recent years, groups working for Tehran have infiltrated the email system of President Donald Trump's campaign, targeted US water plants and tried to breach the networks used by th
Stryker, a major US medical equipment company, said a cyberattack disrupted its global networks Wednesday. "We have no indication of ransomware or malware and believe the incident is contained. Our teams are working rapidly to understand the impact of the attack on our systems," Stryker said in a statement on its website. The logo of Handala, a hacking group linked to Iran, has appeared on company login pages, The Wall Street Journal reported. Stryker's statement said the cyberattack hit its Microsoft programs. Emails seeking additional information were not immediately answered. Stryker is based in Portage, Michigan, and makes a variety of medical products, from artificial joints to hospital beds. It had revenue of more than USD 25 billion in 2025. The company says it has 56,000 employees around the world.
