In a coordinated cyberattack, hackers infiltrated the public address (PA) systems and flight information displays at four airports across Canada and the United States on Tuesday, October 15, 2025. The breaches occurred at Kelowna International Airport and Victoria International Airport in British Columbia, Windsor International Airport in Ontario, and Harrisburg International Airport in Pennsylvania. The hackers broadcast messages praising Hamas and criticizing former U.S. President Donald Trump, along with unauthorized images and music. According to officials, the attackers exploited third-party software and cloud-based systems to gain access. The Kelowna Royal Canadian Mounted Police (RCMP) confirmed that an advertisement streaming service at Kelowna Airport was briefly compromised. Similarly, Victoria Airport switched to an internal system to regain control after the breach. The Canadian Centre for Cyber Security is collaborating with the RCMP and affected airports to investigate the incidents. In the U.S., Transportation Secretary Sean Duffy acknowledged the breach at Harrisburg International Airport, with the Federal Aviation Administration (FAA) also involved in the probe. All four airports, which are smaller regional hubs, reported that their systems were restored to normal shortly after the attacks. The incident highlights vulnerabilities in airport cybersecurity infrastructure and raises concerns about the potential for future disruptions.
