Computer hackers make giant electronic billboard display porn

Drivers in central Moscow stared in disbelief as an electronic billboard showed a two-minute pornographic video in place of the regular advertising clips.

Late-night traffic on one of the Russian capital’s busiest roads slowed as a couple’s explicit escapades appeared across the 27ft display.

The screen’s owner – the 3 Stars advertising agency said a hacker attack was the likely cause.

A city official said that Moscow will bolster security of data transmission to ad screens.

Mobile phone camera footage of the incident has been posted on popular video-sharing websites.
