Just checked twitter and instead of the fail whale I got something different … “This Web Site Has Been Hacked By Iranian Cyber Arm”. Oh dear. At least there’s no destructive payload, no virus installers, just the vandalism. Interesting though, they’ve managed to upload pictures to the twitter servers. There doesn’t appear to be a redirect or anything that would indicate XSS, something twitter has had big problems with. When I hit refresh it’s back to normal. I’m wondering if they’ve managed to get some servers but not all, which may point to cracking the servers...
