One of the Signal users is Mark Zuckerberg, CEO and founder of Facebook. The billionaire’s phone number was indeed discovered in a huge data breach at Facebook. After entering the number into the Signal app, a computer security expert realized that Zuckerberg was well listed among rival messaging users of WhatsApp and Messenger.
A few days ago, Alon Gal, head of cybercrime intelligence firm Hudson Rock, discovered a database containing confidential information on 533 million Facebook users . This data was recovered during a hack into the social network.
This database includes in particular the Facebook identifier, the full name, the date of birth, sometimes the e-mail address, the gender, the date of creation of the account, the place of residence or the telephone number. Among these hacked numbers is the phone number of Mark Zuckerberg , CEO and creator of Facebook.
Mark Zuckerberg is on Signal, the messenger that overshadows WhatsApp and Messenger
Zuckerberg’s phone number was spotted by computer security researcher Dave Walker. On his Twitter account, the expert explains that he discovered the phone number while browsing the database, which appeared on several hacking forums. Other leaked data, including the anniversary date, confirms that it is indeed the founder of Facebook and not a namesake.
Out of curiosity, Dave Walker entered the phone number into the Signal messaging app, a competitor app to WhatsApp and Facebook Messenger. Zuckerberg’s number is well linked to a Signal account. “Mark Zuckerberg also respects his own privacy by using a chat app that has end-to-end encryption and doesn’t belong to Facebook,” laughs Dave Walker.
This discovery is all the more funny since Signal is one of the direct competitors of Facebook Messenger and WhatsApp . Users scalded by Facebook’s privacy practices are turning overwhelmingly to Signal , a messenger that boasts of not collecting user data. Advised by Edward Snowden, the messaging service simply retrieves the telephone number of its users.
If this leak proves that Mark Zuckerberg does have an account on Signal, there is no indication that he is actively using messaging. We imagine that the computer scientist could have installed Signal in order to take a look at the competition.
