Four airports across the United States and Canada had their public address systems hacked to broadcast pro-Hamas messages and insults against President Donald Trump and Israeli Prime Minister Benjamin Netanyahu. The attacks occurred on 16 October 2025, with videos posted on social media showing confused passengers at Harrisburg International Airport in Pennsylvania.
A computer-generated voice chanted 'Free, free Palestine' and used expletives against Trump and Netanyahu. The voice also mentioned 'Turkish hacker Siberislam is here.' The group claiming responsibility, Siberislam, later posted on X: 'Are you ready for a second September 11?'
US Transportation Secretary Sean Duffy condemned the hack, stating it was 'absolutely unacceptable and understandably scared travelers.' He said he was working with the FAA and coordinating with Harrisburg International to investigate. The hack also affected flight information displays, showing messages such as 'Israel lost the war, Hamas won honorably you are a pig, Donald Trump.'
In Canada, Transport Canada confirmed similar hacks at Kelowna International Airport and Victoria International Airport in British Columbia, and Windsor International Airport in Ontario. At Kelowna, staff resorted to using megaphones to provide boarding information while the intercom was down. Windsor airport reported that its terminal was nearly empty at the time, and staff quickly removed the images and shut off the PA announcement.
Authorities determined there was no immediate threat to safety. Scott Miller, a spokesperson for Harrisburg International Airport, said the message was political and did not contain threats. The PA system was shut off, and police are investigating. The group behind the hack, Mutariff Siberislam, is largely unknown and this is its first large-scale cyber attack in North America.
