Twitter,  one of the Internets most popular social networking sites, has been hacked and defaced by a group claiming to be an “Iranian Cyber Army”  as of the 17th at 9:50PM PST.  According to our records, the site was taken offline for exactly 1 hour and 6 minutes starting with the defacement at approximately 9:50PM PST and the outage from 9:57 PM – 11:03 PM PST.  At this point no statement has been made by Twitter, so it’s unclear as to what vulnerability was used to exploit the site.  Oftentimes hacktivism campaigns are fueled by ego-driven script kiddies who use publicly available exploits, but for now we’ll have to wait and see if Twitter decides to publicly announce the details surrounding the attack.

Update 11:20 PM PST: The defacement has been removed and Twitter is back up and running as of 11:20 PM PST.
Update 11:28 PM PST
: Twitter states that the defacement was caused by a compromised DNS server. Full investigation pending.
