Re: Newbie, how can I prevent any internet access?

Another thing to be wary of even if you are behind a router - if you
use the computer running the realvnc server to log onto say a work
VPN, you are no longer behind your own router but that of the work
router and they might not be blocking the realvnc ports. Just
something to keep in mind if using a VPN.

Well, to prevent any internet access, you could also remove the port
forwarding on your router.  If both PCs are on the local network then
the router shouldn't be involved at all.

realvnc 4.1 security issue

[Prasun Lala]

hi, i just learned about the security problem with 4.1 (as someone
logged onto my windows machine as i was using it).
checking my event log over the passed few months i see that remote ips
have logged onto my machine a dozen times. all the logons last at most
a few seconds except for one in june which lasted a minute and a half.
this particular user made changes to my registry switching virus
protection settings off.
i have set back the registry settings to what they were before.
my question: any advice on where i should be looking for changes made
to my computer/any actions taken with my computer beyond the event
viewer? also i was wondering if anybody knows of any standard hacker
scripts that are running exploiting this vulnerability, so i can have
a better idea of what to look for.

Thanks, Prasun
