I got hacked a few years ago, and I paid some ISP tech support guys to find out when and where I got the virus. Using remote access he traced the time and web site I was on when the virus was place on my computer. It was when I clicked on a link posted on the History message boards in their Current Events forum.
Then another tech located where the virus originated from, or I should say, the location where the accessing was occurring from into my computer using
the virus, a root-kit like Z mentioned, that I had unknowingly downloaded onto my computer. It was a server out of Pasadena, California the tech told
You know, while tach support was working the issue finding the location of where the accessing and downloading activity was originating, I was
theorizing India, Nigeria, Russia etc. When they told me it was homegrown issue, I was floored.
So I'll say this to Z.. The next time if you are ever hacked again like you were before, for some extra cash you can get your ISP tech support people
to do some extra work I bet. Yeah, you have to do it under the table, and no it's not something ISP-ers usually provide as a rule to ordinary
customers, but it's not illegal to bribe your ISP tech support folks in asking, "Can you please find out please who is hacking my computer, and for
how much that off the menu so to speak item would cost?". Therefore the next time you are hacked, you can find out, who, for the right price, talking
to the right people who are able to complete such an investigation. After all what is the worse that could happen? Tech support saying "no."
