Hi Davide,

I also have same problem since Friday. Do you have VNC server on your PC always running? Then disabling it may help.
I found that VNC Server icon on task tray was in Black when I had such problem, as if "somebody" was connecting and playing with my PC Shocked
I think it's due to a kind of virus program which is running on my PC and simulating remote control....
Probably it's very new virus and no anti-virus program can detect yet? I tried 2 checking programs (CA and Trend-Micro) but didn't find anything.

Hi Kino,
yes i do have VNC 4.1. free edition and i have done the upgrade to the 4.2.6 version. Actually it seems that the problem stop. But i think that i still have the program on my pc. I think its a rootkit. My AVG Antivirus and Spyware doctor antispyware cant see that malware. To monitor what happening on my computer i downloaded these programs : net alert 2001
curr ports
to detect rootkit and protect i use : cyberhawk and sophos anti rootkit
to check the status of my vulnerability i used Shields Up! on this site
Anyway i have seen around that we arent just us with that problem.

Good times with the RealVNC 4.1 Authentication Bypass Vulnerability
Patching your system should reduce the risk that you'll be compromised again. An attacker can use leverage this issue against you in order to establish a remote session with your PC without knowing your VNC password. This isn't just you.

Post exploitation the attacker appeared to create an FTP script in order to download a utility named 112.exe. This is likely a backdoor/rootkit/nasty nasty thing designed to allow the attacker to maintain control over your machine.

Getting rid of it? Well I've got no idea what 112.exe is but you may want to head over to the HijackThis forum on this site. They're insanely intelligent when it comes to these kinds of things, and maybe they'll be able to help you out.

was wondering if there was an update to this. I have been getting the same thing... everytime though it is a diffrent exe file ... on each machine. is there a new worm out that is doing this automated now? seen 3 computers.. diffrent exe file names.... and located in 3 diffrent countries... trying to find a common link between them.

Thanks for any information you can provide. I am at a loss.... I would think VNC ... 4.1.1 but... at least one of the users.... running a firewall on the laptop... plus a hardware firewall/GW and managed to get the same thing....

virus scans turn up nothing...

I upgraded VNC Viewer to the professional version and the problem has gone.
