Mark Zuckerberg has long been an advocate for a more ‘open’ Internet. After claiming that privacy was “no longer a social norm” back in 2010, the Facebook founder has actively encouraged a “bolder” approach to online sharing; with over 1.5 billion users now storing their personal information on the social site.

Unfortunately, though, it seems like he may not be actually practising what he preaches. According to a new picture posted on Zuckerberg’s official account yesterday, the CEO appears to be much more stringent about his own privacy than that of his users – with the image revealing that he tapes over both his laptop webcam and his headphone jack.

Often dismissed as a security tactic for the hyper-paranoid, taping over your sensors apparently stops hackers from breaching your system and taking control of your camera. It has reportedly been adopted by some of the most powerful names in US security; including the director of the FBI, James Comey. “I put a piece of tape over the camera because I saw somebody smarter than I am had a piece of tape over their camera,” he once admitted. 

The move may have been a paranoid response to claims earlier this month that Zuckerberg had had his Twitter, Instagram and Pinterest accounts broken into. According to various reports, hacker group OurMine managed to discover the CEO’s password – which was reportedly just “dadada” – by looking into a LinkedIn database. “You were in Linkedin Database with the password ‘dadada’!” the group gloated on his Twitter shortly after.
