A huge wealth of hacked data from more than 500 million Facebook users was made easily accessible Saturday – including Mark Zuckerberg’s mobile number, according to a security expert.
The information was initially stolen in January, after hackers exploited a vulnerability involving phone numbers linked to Facebook accounts, eventually creating a massive database of private information.
According to Bloomberg, the database became directly accessible to people with basic data skills on Saturday after it was posted on a hacker forum.
Facebook dismissed the data as “very old,” but security expert Dave Walker pointed out that the company’s own CEO had been a victim of the hack.
“Concerning the #FacebookLeak, of the 533 million people in the leak – the irony is that Mark Zuckerberg is unfortunately also included in the leak. When journalists struggle to get an explanation @facebook, maybe just call him, from the phone in the leak? ” he tweeted next to a screenshot of Zuckerberg’s name and information with the phone number partially invisible.
