Someone hacked into my PC??? I think..

[dave_s13]

Just sat on my PC and all of a sudden the mouse starts doing it's own thing. It has remote desktop installed so I can mess about with it on the laptop downstairs.
So I turn it off, leave laptop on and go out.

Come back and the laptop is locked with the desktop picture showing but no icons. Press the off button and it says someone is logged into this computer, sure you want to shut down? Yes/No/Cancel etc.

Router has logged this lot:-

I have no idea about internet security, windows firewall is switched on on both machines but that's all.

Router is a Netgear DG834GT.

Can someone explain what happened and how I stop it?

Cheers in advance.

Is your router locked, i.e. do you have to enter a passwword to connect?

[dave_s13]

Yeah but it was set to the default admin/password.

Just changed the password.

[Smiler.]

No, I meant the WEP access key.

With your mouse behaving odly, it sounds like remote assistance has been enabled.

Sounds like a hack.

What is your setup, PC, router connection, wireless etc.

[dave_s13]

I've got WPA-PSK enabled.

Router is a netgear dg834gt
PC with wired ethernet link (windows XP) this has remote assist enabled.
Laptop (win XP) wireless link this had remote assist on but just turned it off
xbox 360 wired ethernet
Pinnacle Stream Center wired ethernet.

Seeing lots of stuff like that in the router logs is 100% normal, that in it's self doesn't mean anything. Also, not unusual for the mouse cursor to move by it's self with optical mice.

DOS=Denial Of Service attack. Looks like a load of compromised machines were pointed at your router. Make sure remote (WAN) management is turned off on the router.
