Leaked phone number reveals even Mark Zuckerberg is on Signal
Facebook co-founder Mark Zuckerberg apparently used the Signal app.
A security researcher used his number to confirm he had a Signal account.
Zuckerberg’s number was one of millions leaked in a 2019 Facebook hack.
It was revealed just a few days ago that phone numbers and other details belonging to 533 million Facebook users had leaked on a hacking forum. The trove of data may have been obtained via a 2019 vulnerability that has since been patched, and it turns out that Facebook co-founder Mark Zuckerberg’s phone number was leaked as well.
