My house was recently broken into and among other things my brand new macbook pro was stolen. Since dropbox is always running on my computer, I was able to use my account's "last activity" info to discover the ip address of my thief.
Any suggestions for some next steps?
A phone home virus which you can drop into your dropbox and give it your sudo password. It can do funky stuff like install preyproject silently.
Also, since you know the IP, do a ns-lookup of the IP and identify which internet provider owns that IP and follow it up with them. They would be should be able to let you know which customer was using that IP address.
Note it is not as simple as it sounds cause due to privacy laws, you can't just call up a service provider and demand the identity of a user behind an ip address. Usually, only the police have the right to investigate this hence why you should start with them.
Sorry to hear about your bad luck. Hope this helps.
Do you have a persistent connection to a vpn or something you can check?
In the future, make sure to use something like Prey and test it.
For everyone else the bare minimal thing you can do is install something like Prey Project http://preyproject.com/ . Good luck
For example, I'm not recommending confronting them yourself, but if you had credible documentation that turned that IP address into a street address, with a demonstrated continued presence of the stolen property, this might get acted on if the detective thought a judge would readily generate a warrant, and/or the suspect might be a source of other/continued criminal activity, and/or whatever else.
I don't know whether this has any merit, but if you're on good terms with your insurance company, you might mention the situation. Although, again, for a low value crime (from their perspective), it may be more cost effective to simply pay what the policy says is your due, rather than to "solve" the crime.
Part of the problem for you and other people in this situation: Unless you have an insurance policy far different from the typical homeowner's policy, there is no coverage of the value of your data and so no financial incentive to foster its recovery.
(Even from an identity theft perspective, it's cheaper to sign you up for monitoring than to recover the stolen data.)
This all is just my interpretation of such situations, for whatever value it has. I may be wrong, but this is how I see it, in general.
