Overview

• Transport Canada confirmed breaches at Kelowna and Victoria, B.C., and Windsor, Ont., while U.S. incidents included Harrisburg, Pa., with Oregon also reported.
• Unauthorized audio and on-screen text praised Hamas and insulted President Donald Trump and Israeli Prime Minister Benjamin Netanyahu, but contained no threats.
• Kelowna officials said a third party accessed flight-information displays and the PA system via a cloud-based provider, a vulnerability Victoria also cited.
• Operations resumed quickly; Harrisburg searched a boarding aircraft as a precaution and it departed safely, and Kelowna reported two significant flight delays.
• A social-media account labeled “Siberislam” was credited in some messages and claimed responsibility online, though investigators have not verified attribution.
