The Syrian Electronic Army hacking group today targetted several news websites, including CNBC, Britain's Telegraph and PC World.

Other media organizations affected include the U.K.-based Independent, the London Evening Standard, the New York Daily News, betting site William Hill, La Repubblica newspapers and PC World.

"Happy thanksgiving, hope you didn't miss us," said a message posted to a Twitter feed that appears to belong to the hacking group.

The Syrian Electronic Army, which backs the country's president, Bashar al-Assad, has in the past targeted the New York Times (NYT) website and also claimed responsibility for hacking the Washington Post and the Financial Times last year.

The group hacked Gigya's web address to upload a message to other websites.

A U.S. firm that helps connect more than 700 companies with customers through social media says a Syrian group hacked the company's web address to upload a message to other websites. Users of the sites were presented with a message telling them that they "have been hacked by the Syrian Electronic Army."

Gigya CEO Patrick Salyer said that hackers rerouted Internet traffic from its website to a computer server that generated a message to visitors that their site had been hacked by the Syrian Electronic Army. He added that no user or company data was compromised in the hack.
