How do i stop a hacker?

post #1 of 48
Thread Starter 
I have been hacked. here is what happened:
I setup i minecraft server for a few friends with hamachi. I had it running for a few days, then I came to my computer, and saw the mouse moving around, randomly opening up programs. I immeadiately shutdown the computer, and used my other computer. the next day, my brother came into town and we installed hamachi on his computer to play minecraft. A day later, his computer has the same problem.
since both of these computers had hacking problems a few days after installing hamachi, I came to the conclusion that someone was taking remote access of my computer through hamachi. So, I uninstalled hamachi on my brother's machine.
It worked hacker-free for a few days, but now someone is taking remote access of the machine, even after removing hamachi. Now, I have concluded that the hacker has placed a remote access software on my brother and I's PCs, and no longer requires hamachi to hack our PCs.
SO:
How do I remove the remote access software and end the hacker problem once and for all? Really don't want to reload the OS, so I will try anything else first.
Thanks in advance

check for changes... turn on the pc with internet unplugged and poke around. See iyou see anyhting installed that shouldnt be...

my bro had the same thing happen to his pc only the guy went through his on our network and isntalled it onto my pc. Got into my hotmail, found thigs he shouldnt have, posted it on 4chan, then got the police involved XD it evolved very rapidly and can be a pain. Its nto worth the risk tho if you dont find anyhting reinstall the os

Download a couple antivirus/malware programs and throw it on a thumb drive. Scan it and see if you're getting any hits. Make sure to disconnect it from the web.

Take out the hard drive, put it in a non-infected PC and clean it out. Run malware bytes, scan it with whatever your virus program is. And manually clean it out.


If you just run them directly on that PC it most likley wont find anything at all.

Change the port Hamachi uses and add security credentials to access the computers.

Hmm, well that is a problem, and I am no hacker defender, but somethings I can think of are:

Make sure you have a dynamic IP
Get a good anti-virus/firewall
You could try bridging that computer's internet through a laptop, that might help.

If it comes down to re-installing, make sure you open up a notepad for the hacker and leave him a little message before you re install

I did a little searching around, but didn't find anything in particular.
I did research how the hacker did this, I think it is known as "netbios hacking"
tomorow, I will search the pc with antivirus, and post my results. thanks for the help so far

Just make sure to disconnect it from the web when you head to bed.

You actually should have known, that once you saw the mouse moving without your physical action, the immediate thing to have done was to pull the plug on the modem. Of course, if it's never happened to you then you don't know. But now you do!

As for how he got in, I suggest you do a few things.

* Lock down your router. Use a very long password. Make sure the firewall on it is on and functioning. Be sure the right ports are closed. Here is a good place for starters. Read up on router security.
* Lock down your PC. For peace of mind, make a few user accounts - one with full access that you only use when you're installing the important stuff (drivers, system changing software, etc) and one or a few you can setup as very limited ones (one for gaming, one for surfing and email, one for school work, etc). This way if you're not logged on as an admin, and you're attacked blatantly, then your attacker won't have access to a few things that he could alter for his benefit.
* Use encryption for specific folders containing important information. My Documents on my drive is encrypted and the key is on a removable drive.
* Install a software firewall so you can better monitor incoming and outgoing traffic.
