Nude pictures of former French first lady Carla Bruni were used to break into the computer systems of dozens of diplomats, it emerged today. The shocking security breach was first discovered at the G20 summit in Paris in February and may be ongoing. Once accessed, the Trojan Horse infected the computers of senior officials as well as forwarding the offensive email on to others. Sarkozy was first embarrassed by nude pictures of Bruni surfacing shortly after their marriage, while they were staying with the Queen at Windsor Castle during a state visit to Britain. The so-called phishing attacks are thought to have originated in China and were aimed at extracting information.
