Sidat.ID, – Because Facebook CEO Mark Zukerberg’s phone number emerged from the leaked data of 533 million Facebook users, security experts have revealed that Facebook CEO uses Signal.
The leaked data reportedly included Zukerberg’s phone number, Facebook user ID, personal details such as location, wedding details, and date of birth.
“On another occasion, Mark Zuckerberg respects his own privacy, using a chat application that has end-to-end encryption and is not owned by @facebook,” wrote Dave Walker, Twitter security expert.
“This is the number associated with your account from the recent Facebook leak,” Walker posted along with a screenshot of Zuckerberg’s leaked phone number that read, “Mark Zuckerberg is on Signal.” Recently, the personal data of nearly 53.3 million Facebook users, including 61 lakh from Indians, resurfaced online after a hacker posted details on a digital forum.
The easy availability of data can make users more vulnerable to cybercrime, although Facebook says it is “old data.”
“The 533 million Facebook records have just been leaked for free. This means that if you have a Facebook account, the phone number used for that account is likely to be leaked, ”tweeted Alon Gal, chief technology officer for security firm Hudson Rock.
News of the data breach was confirmed by Facebook to The Record.
“This is old data that was previously reported in 2019. We found and fixed this issue in August 2019,” a Facebook spokesperson said in the report Saturday night.
Signal recently became the fastest growing app globally in both downloads and monthly active users (MAU) in the first quarter of last year, according to data provided by app analytics company App Annie.
Signal has gained immense popularity due to its simplicity and focus on privacy.
