I have a Windows 2003 server and I think I have a security issue with it. The default language was mysteriously changed to Chinese, I changed it back. I keep seeing lots of connections on my SonicWall to port 80 from all kinds of IP's from China. I already blocked lots of Chinese IP ranges on my SonicWall. I wish there was a network group object that i could import that contained all the country IP ranges of all the bad guys. At this current moment I don't see any Chinese connections but I'n not convinced this is fixed yet.
I noticed that the IUSER_WEB was a member of the Administrors group which sounds very fishy. I've disabled the IUSR_WEB account for the time being. This server also just passed a malwarebytes scan test and its all up the date on Microsoft updates. What is the default security assigned to the IUSR_WEB account? I need port 80 open on this machine since it does host a small webpage. Anything else I should be looking at? Thanks!
