The hacker spammed artist Neil Young's twitter feed with WARNING pics and links (and retweets from infamous pr0n sites) before being taken down. The power of social media, everyone!
UPDATE: Experts at Errata Security are quick to point out that this report is full of misleading information. For one thing, much of the reporting is done from Moscow, over 1000 miles away (thus making concerns of physical location less conclusive). Secondly, much of the malicious software in question would have to be willingly downloaded and installed. Though many Russian-based Olympics sites may be questionable, it has nothing to do with Sochi itself.
In light of the tragic events of May 20, 2013, when a massive tornado struck Moore, OK and killed at least 24 people, the Westboro Baptist Church, perpetually high in the standings for 'Worlds Biggest Scumbags,' made the website GodHatesOklahoma.com.
A hacker known only as The Jester wasn't having any of WBC's crap though. He stole the domain name right out of the church's hands, made the above image of Jesus flipping the birdy as the site's welcome screen, and redirects it after 5 seconds to this page.
Well done, Jester. Well. Done.
