This week’s most popular story was the news that hackers had broken into the US Department of Defense’s $300bn (£206bn) Joint Strike Fighter programme, which is partly funded by the UK. The hackers copied data relating to the aircraft system design by exploiting network vulnerabilities in computer infrastructure belonging to contractors helping to build the new planes.

Those in the market for a new smartphone got an additional option this week with the arrival of the Nokia E75 in the UK. The handset is designed to bring full desktop email functionality in a mobile device, and also lets users set up separate business/personal home screens.

Meanwhile, a guilty verdict for the Pirate Bay four led to protests in Sweden at the weekend by demonstrators angry over the one-year jail sentences handed down to the file-sharing site operators.
