Diagnosing a Compromised Computer

Tracking down what a hacker has done to your computer is difficult and time-consuming. You should contact the Computing Help Desk at 646-2999 or your department's computing support office for advice.

Some symptoms of possibly being hacked include, but are not limited to:

  • The Symantec AntiVirus icon in your system tray will have an X through it or the inability to retrieve the latest virus definitions when the LiveUpdate button is pressed.
  • Your hard drive light flashes continually, even when you are not doing anything on your computer.
  • Your computer is noticeably slower to perform routine activities.
  • There is a User account on your computer you don't recognize.

The ramifications of not dealing with a computer that has been hacked include:

  • The transmitting of files on your computer to someone you do not know.
  • Having a group like the Record Industry Association of America (RIAA) sue you because the hacker set up your computer to share copyrighted music.
  • The inability to use your computer because the hacker has filled up your hard drive.
  • The inability to use your computer on line because the College network has blocked your connection due to high or unusual traffic.
  • Slowing down the network for everyone else at Dartmouth because your computer is using so much of the network bandwidth.
  • The transmitting of your user name and password to someone else that would give them access to your e-mail account and all of the other resources you have access to that require you to log in.
