Mark Zuckerberg Facebook account hacked

Score one for the hackers. On Wednesday, a cyber-prankster successfully commandeered Mark Zuckerberg's Facebook account, and used it to post an anti-Facebook screed on the official Mark Zuckerberg fan page. The note, which has since been removed (along with the entire fan page), seemed to reference recent investments from banks such as Goldman Sachs:

Let the hacking begin: If facebook needs money, instead of going to the banks, why doesn't Facebook let its users invest in Facebook in a social way? Why not transform Facebook into a ‘social business' the way Nobel Price winner Muhammad Yunus described it? http://bit.ly/fs6rT3 What do you think? #hackercup2011

Wordy, sort of interesting – and definitely not actually written by Mark Zuckerberg.

So who is behind the Zuckerberg hack? Theories abound. Over at the Guardian, Charles Arthur concludes that the hacker must be the same person who edited a Wikipedia entry on Social business. (Arthur's reasoning is pretty sound, but his explanation is long and byzantine and almost impossible to summarize. Read it in full here.) From that Wikipedia entry, Arthur produces an IP address: 131.74.110.168.

And that IP address is apparently registered to the US Department of Defense office in Williamsburg, Virginia. "In other words: this might be someone in the military," Arthur writes. "Most likely those edits don't come from one person – they come from all sorts of people in the Williamsburg location. Or, just as possible, it was someone who had hacked into the computers there from outside... and is using them as a proxy to make the Wikipedia edit." (Our own IP searches trace the number to a DoD Network Information Center outside Columbus, Ohio.)

Theories? We're listening.
