When i accessed our Server 2013 this morning someone had logged into it without permission.

 

They had opened Mozilla Firefox browser and had opened the following webpages:-

 

www.speedtest.net

www.xnxx.com

https://videos1.cdn.xvidoes.com

https://c9.io/login

 

https://c9.io seems to be some sort of developers website.  

 

We ran Malware which found the following C:\Users\adminnew\downloads\setup.winrar.exe

 

They had set up a new User on the Server as adminnew.  We have removed this user, changed the password on the Server and removed any ports on the router that we don't need to have open.

 

Is there anything else we can do to increase security?

 

Also has anybody had anything similar happen to them?

Find out how they got in if possible. Could have been a fishing campain, brute force, or a sticky note depending on company policies. Plug that whole and stop using admin accounts for maintenance on the servers. Login with a standard user granted access and enter the admin credentials when needed. Run malware, adware, and rootkit scans. Is it possible a vendor was setting up software?

If you found these apps open, it means they logged in with your username and password.

 

Or did you log into the server with a generic local account? If so, is this generic account on other computers/servers? You may want to update via GPO.

 

 

Check DC Event log, for audits of that server, you should be able to locate the source IP of the login, and find out if this was external or internal and do further digging from there.

 

As Sneaky has said, its possible it was just Dev if its a generic account.

 

Or if it was an attacker, they could of left rootkit to gain access again remotely.
