Barack Obama’s website was hacked and showing “Hacked by SEA”

United States’ president 
Barack Obama campaign website was hacked by hackers Sunday evening, website visitors were automatically redirected   to Syrian Electronic Army 
(a Syrian hackers group)                          

website, The Blaze reported. Visitors were introduced with a message “Hacked by SEA”

 The campaign website donate.barackobama.com was redirecting visitors to ‘sea.sy/indexs/,’ sea.sy is the website of Syrian hackers group Syrian Electronic Army, but hackers group haven’t tweeted about the hack so the hack might be done by other hacker group and they promoted SEA as hackers.
The donation page that was compromised, however, appeared to have been old. The Obama campaign has most recently been using another page on the website, contribute.barackobama.com, to solicit donations, The Blaze writes. Syrian Electronic Army is a hacker group which gained prominence through the hack of AP twiiter account, after that the group also hacked dozens of twitter accounts of media and others.
