The Syrian Electronic Army, a hacking group that claims Arab and western media present a biased view of Syria's civil war, has committed previous cyberattacks on news outlets including the Associated Press, the BBC and al-Jazeera.
In the latest incident, 12 posts titled "Hacked by the Syrian Electronic Army" appeared on the Financial Times tech blog Friday, and official Twitter feeds were disrupted, the newspaper reported.
"We have now locked those accounts and are grateful for Twitter's help on this," Robert Shrimsley, managing editor of FT.com, said.
Someone claiming he was with the Syrian Electronic Army, interviewed via email last month by the Financial times, said the group would target the media of "all the countries who support the terrorists groups in Syria."
A number of FT employees had been sent phishing emails in the days leading up to the attack, executives said.
"Unfortunately this is an increasingly common issue for major news organizations," Shrimsley said.
