Hackers breached the public address and information systems at four airports in the United States and Canada, broadcasting pro-Hamas messages and insults directed at political leaders. The incidents, which occurred at Harrisburg International Airport in Pennsylvania and three Canadian airports, included threats and graphic images, causing confusion and concern among passengers and staff. Authorities quickly shut down the affected systems and launched investigations, determining there was no immediate threat to safety. The group responsible, identifying itself as Mutariff Siberislam, has claimed responsibility for similar cyber attacks in other countries, but this marks its first major operation in North America.
