View Full Version : Site security issues

05-10-2008, 12:14 AM
A few months ago, I noticed that the front pages of one of my websites (a simple HTML/CSS affair) appeared to be laggy and unstable, causing Firefox to crash. Some of the sites users reported that their work firewall blocked the site and reported it to be infected. I even got such a warning from Google, and was informed that my site would be flagged as unsafe in search results.

Upon further investigation, I noticed that somehow, a random JavaScript function had been added to the end of the webpage. I removed said function, which appeared to resolve the issue. I filed a request with the sites host, who said all was well on their end and the problem was with my machine.

I checked my site this evening, and low and behold a new random JavaScritp function has appeared out of no-where, and the page is crashing again. Could anyone shed any advice on how this is happening? Do I need to chance my FTP credentials? Could it be some exsiting files on the server? Would it indicate my PC has some form of virus? (I use good AV software, a firewall on our wireless router, and am a very careful internet user).

Thanks in advance for any help with this issue.

If you suspect that someone is accessing your site through your FTP credentials, then I'd recommend changing your passwords and checking your machines for any malware.

Are you on a dedicated server for your web host or are you on a virtual server with other sites? (If you are unsure, usually dedicated hosting costs a lot more and you'd know it if you were)
