What can be done? I've already blocked the IP but I want this schmucks head.
This has cost us, at the current time, 14 hours of labor to clean up.
However, most of the damage was to the accounts of our customers which once he gained access to them he proceeded to do whatever he could to damage. This has cost our users an unknown amount of time today in attempting to clean up the 'mess' he has caused.
If it's a company, call them and let them know what happened - they might be able to figure out who was using the IP address and would quite possibly fire them for unauthorized use of their Internet access. If it was an ISP, they may terminate their user for violating their access policies.
There isn't much you can do legally since there really wasn't any damage done - changing a few settings doesn't constitute damage. Unless credit cards were compromised of course, then you can just call the FBI and let them handle it. But other than that, its best just to let the company or provider know what happened.
Also keep in mind that though unlikely, it's possible that the person at the IP address you have had nothing to do with it and knows nothing about it - these types of attacks are typically done via software or scripts, and there is no way to tell whether the person sitting at that PC was deliberately running a program to test logins or whether they were infected with something that does it without their knowledge.
You should also consider upgrading your login security a little bit ... perhaps ban an IP if their login fails more than 3 times.
Your claim is that a crime was committed against your property. If you are serious, make a police report. Gather up all your evidence. Take a few days to fully think about the situation. Then if you want to proceed, take your evidence to your local District Attorney. In all likelihood, the DA will blow you off because he/she has neither the time, interest, nor the ability to prosecute. Another lesson that life just is not fair.
That's just one practical starting point. Maybe others can point you in a different direction.
Good luck. I hope you get his head served up on a platter.
