Twitter, which in June became a key communication channel for Iranian protesters disputing the country’s election results, said it was disrupted for a little more than an hour.
Twitter’s home page was replaced with one whose headline read ‘This site has been hacked by Iranian Cyber Army’ and an anti-American message.
“The motive for this attack appears to have been focused on defacing our site, not aimed at users,” Twitter said on its blog. “We don’t believe any accounts were compromised.”
It was unlikely that the Iranian government was involved, despite its dislike of social networking sites and years of discord with the US over its nuclear programme, experts said.
