Facebook Data Harvested to Build List of Likely Logins

A researcher published a torrent file containing the name of every Facebook user that hasn't specifically opted out. The list was obtained by harvesting a public directory that Facebook maintains.

This list was then used to determine the likely variations of "first initial last name", "first name last initial" and so on, which could be helpful at increasing the success of users attempting to log in to systems using brute-force tactics.

The next step the attackers do is to infect all (and I mean all!) PHP files on the compromised web site. If it's a shared web site, and the permissions are not setup correctly, they will actually infect absolutely every web site hosted on that machine,"
