The Syrian Electronic Army (SEA), a Syrian based hacker group known for redirection and denial of service attacks on media and political targets, briefly altered links from Obama’s social media sites to point to videos created by the SEA.
The attack was made possible not by hacking the websites, but by compromising the link shortening service that the President’s campaign team used on several websites.
According to the SEA’s twitter feed, for a while Twitter eventually blocked the links all together and visitors saw this:
In a series of e-mails to news site Mashable, allegedly the SEA hackers claimed they compromised BarackObama.com by attacking one of the site’s administrators:
“In a follow-up email, the SEA provided screenshots that show how it altered the links in Obama’s social media posts. The group appears to have hacked the email address of Suzanne Snurpus, one of the administrators of BarackObama.com, and it gained access to a control panel for the site.”
