How Can I Tell If I've Been Hacked?It's generally difficult to tell if a system has been hacked for certain, but some things to look for include :
- Your system clock suddenly switches to some other timezone, and/or the time/date change dramatically.
- The login procedure on your system changes, or you can no longer log in.
- You find a directory named "...", or ".. ", or something simliar.
- The system suddenly seems much slower, and you can't find a process or memory related reason for it.
- You find processes running which don't seem to belong.
- You find entries in your logs or using the last command, which show someone logged in, at odd hours or from non-local places.
How can I secure my Windows/Unix/MacOS computer?In general, the following will help you better secure whatever system you have.
- Keep up with system patches, and keep the operating system itself up to date! (Plan on rebuilding most systems once per year)
- Stop all running services which you don't intend to use on the machine.
- When installing a machine, don't connect it up to the network until after you've patched and secured it.
- Monitor the system logs daily/frequently, and log everything you can.
- Use good passwords, the longer & more non-alphabetic the better. Change them often.
- Use ssh instead of telnet, ftp, and rlogin/rsh.
