An electronic roadside billboard is the latest victim of a cyberattack, after hackers broadcasted pornographic material on the screen in Milton.

It was the screen on Milton Road, beside the inbound lane past the Milton Tennis courts and before the XXXX Brewery.

It took Goa, the operator of the billboard, three minutes to regain control and take down the adult movie on Sunday morning.

They are saying the porn was on the billboard for between a number of seconds up to three and half minutes.
