Technology website TechCrunch was forced to go off-line last night after a hacking attack.
The website, which is now back up and running, said:
"Earlier tonight techcrunch.com was compromised by a security exploit.
We're working to identify the exploit and will bring the site back online shortly."
According to Graham Cluely, technology consultant at Sophos the site was replaced with a message linking to a site containing links to adult material.
"As far as we can tell at this point, the site was not infected with malware. If that is confirmed then we should all be grateful, as TechCrunch is tremendously popular with those interested in technology," he added.
"There's no such time as a 'good time' to be hacked of course, but one can only imagine that today is a better day for TechCrunch to be hacked than tomorrow. That's when the site will be expecting a large amount of traffic as millions of people around the world look for information about the new iSlate due to be announced by Apple.
