Can you believe that Facebook CEO Mark Zuckerberg has an account on Signal? Well, yes, that's right. Among those 533 million Facebook users, the CEO's data was also leaked. And as per reports, his name, location, marriage details, birth date, and Facebook user ID also got out apart from his phone number.

A security researcher, Dave Walker, disclosed the fact by taking it to his Twitter handle and sharing it with the whole world. The post reads, "In another turn of events, Mark Zuckerberg also respects his own privacy, by using a chat app that has end-to-end encryption and isn't owned by @facebook. This is the number associated with his account from the recent Facebook leak," with a screenshot of Mark's account on Signal.

This outrage happened when millions of users were disappointed with Facebook owned-WhatsApp's new feature updates. The updated privacy policy of WhatsApp states that it gets access to user's chats which are linked to business profiles. 

Dave Walker further posted on Twitter,  "Regarding the Facebook leak of the 533M people the irony is that Mark Zuckerberg is regrettably included in the leak as well." The co-founders Chris Hughes and Dustin Moskovitz were also affected by this breaching.
