In January 2021, it became known that hackers were able to use the information to gain access to users’ phone numbers; The leak has now been expanded to include “phone number, Facebook ID, full name, location, previous location, date of birth, (sometimes) email address, account creation date, relationship status, bio.”

“Bad players will definitely use the information for social engineering, fraud, piracy and marketing.”
Cryptocurrency users are at risk of such attacks.
