Mark Zuckerberg uses Signal; Phone number leaked

Compromised data of 533 million users were leaked from Facebook recently.  Among the leaked data Facebook CEO Mark Zuckerberg’s phone number which is registered with the Signal messaging app was revealed. Zuckerberg’s other details such as his name, birth date, location, marriage details, and Facebook user ID were also revealed. This may seem to be the biggest data leaks ever.

A Security researcher revealed that Mark Zuckerberg is using the Signal app by posting his leaked phone number which verifies that Zuckerberg uses the Signal App

Security expert Dave Walker posted on Twitter along with a screenshot of Zuckerberg’s leaked phone number which mentioned, “Mark Zuckerberg is on Signal.” He also stated “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,”

“Regarding the Facebook leak of the 533M people, the irony is that Mark Zuckerberg is regrettably included in the leak as well,” Walker further mentioned in another tweet.

According to reports, Facebook’s co-founders Dustin Moskovitz and Chris Hughes were also among those affected by the data leak.

As Alon Gal, a security expert mentioned the data was leaked last year because of a vulnerability that exposed the phone numbers linked to every Facebook account.

However, Facebook stated the vulnerability was detected in 2019 that led to millions of users’ phone numbers stolen from its servers. They confirm that the vulnerability was resolved in August 2019.

Nevertheless, of the 533 million users, 32 million belonged to the US, 11 million to the UK, and 6 million to India. As per a Bloomberg report, the database of stolen phone numbers was posted on a hackers’ forum and could be simply transferred to anyone with basic computing skills.
