"Alert the appropriate authorities by contacting:

* your ISP and the hacker's ISP (if you can tell what it is). You can usually find an ISP's email address on its website. Include information on the incident from your firewall's log file. By alerting the ISP to the problem on its system, you can help it prevent similar problems in the future.
* the FBI at www.ifccfbi.gov. To fight computer criminals, they need to hear from you."

This is useless contacting the attackers ISP? it's the attacker computer just a hijacked
