The website of the popular Javascript jQuery library has been attacked for the second time this month by unknown hackers.
Today's attack on jQuery.com was confirmed by jQuery evanglist Ralph Whitbeck, after the infrastructure team for the site received widespread reports of a compromise.
Whitbeck said the attackers had aimed to deface jQuery.com, rather than inject malware as had occured in an earlier attack this month.
To mitigate against further attacks, Whitbeck said jQuery.com has been moved to a new server that is only running trusted code.
"At no point today have there been reports of malware being distributed from any of our sites, nor has the code of any jQuery libraries on our website or content delivery network been affected or modified today or during last week’s reported attack," Whitebeck wrote.
He said there had been no compromise of developer accounts as the site does not have public user registration.
Whitbeck said jQuery.com was continuing to monitor the situation and would provide updates for users as they become avaiable.
According to metrics measurment firm BuiltWith.com, jQuery is used by just under 50 million websites. Of the top 100,000 websites monitored by Quantcast, two-thirds use the Javascript library.
