As many as 1.5 billion Facebook users' personal data, including their names, addresses, email addresses and phone numbers, have been put up for sale on a hacker forum, Sputnik news agency reported Monday.
In late September, someone posted on the forum claiming to have data on 1.5 billion Facebook users. There were also offers -- one potential buyer offered $5,000 per million user data. That means the total value of the user data held by the "seller" is $7.5 million, Sputnik said.
The compromised user data included name, email address, location, gender, phone number and user ID.
Privacy Affairs, a website focused on data Privacy and Internet security, also noted that the latest facebook user data leak appeared credible because, compared with previous breaches, it was not old data for resale, but new data.
However, several users on the forum revealed that they did not receive any Facebook user data after sending money to the posters, suggesting that the so-called "leak" could be a hoax or due to a delay in delivery by the data holder.
