A cybersecurity professor has insisted he was not hunting for a vulnerability when he found a denial-of-service bug on an in-flight entertainment screen during a long-haul flight. His findings could affect a number of airliners running Thales-made equipment.
But Hector Marco, an associate cybersecurity professor at the University of the West of Scotland, has received a kicking on social media from some in the security industry over his research method.
At the start of a commercial transatlantic flight he took in February, Marco pasted long strings of text into an in-flight chat app using a USB wireless mouse.
