The phone number, address, personal identifier of Mark Zuckerberg and some other information got into the public domain. Walker also joked that if journalists cannot get his comment, they can contact him at the number leaked to the network. In addition, the database contains the personal data of two other founders of the platform - Chris Hughes and Dustin Moskovitz.+
"Regarding the #FacebookLeak, of the 533M people in the leak; the irony is that Mark Zuckerberg's data is also available in the leak as well," Walker tweeted.
A global data leak from Facebook happened on April 3. Unknown persons have posted the personal data of Facebook users publicly on one of the hacker forums.
The list includes information about Facebook users from 106 different countries. The maximum number of leaked records belongs to users from Egypt (44 million); then Tunisia (39 million), Italy (35 million), the United States (32 million) and Saudi Arabia (28 million).
Hudson Rock researcher Alon Gal believes that attackers can use the database to hack user accounts; and fraudulently through social engineering.

The leak provides cybercriminals with valuable information; that can be in use to impersonate another person or fraudulently obtain user credentials. Alon Gal, CTO of cybercrime intelligence firm Hudson Rock, who discovered the leak, said: “A database of this size, containing personal information such as the phone numbers of many Facebook users, will certainly lead attackers to use that data to carry out attacks related to social engineering, or hacking attempts”.
"Individuals signing up to a reputable company like Facebook are trusting them with their data and Facebook [is] supposed to treat the data with utmost respect," Gal said. "Users having their personal information leaked is a huge breach of trust and should be handled accordingly."
