It looks to me like they're saying the security consultant compiled what is easily available via FB, no hacking involved. I don't know for sure, because I haven't gotten through to the security consultant's site, or looked at the database.
The personal details of 100 million Facebook users have been collected and published on the net in a downloadable file, meaning they will now be unable to make their publicly available information private.
Facebook, meanwhile, downplayed the issue, saying that no private date had been compromised.
The information was posted by Ron Bowes, an online security consultant, on the Internet site Pirate Bay to highlight privacy issues, the BBC reported.
I gave you the NBC New York article instead of the BBC version, because the NBC article has live links to Pirate Bay and the security consultant who posted this data. Don't imagine that those links have been working consistently today! There are something like 300 million FaceBook users. The security consultant's site is crashed and Pirate Bay is struggling.
