So,

On Monday the 17th my HP DV7 was stolen along with my cousin's laptop from work.  An opportunist managed to somehow make his way in to the building in the exact 4 minutes nobody was around to see him.  We caught on to the operation about a minute after it happened, but things looked bleak.  I didn't have a serial number for my laptop at the time.  We didn't even have security footage of it happening.  To make things worse, I had just wiped my computer and re-installed everything and was enjoying the convenience of not having a password before anything important went on it.

It was gone with no leads.  This felt calculated.  To get to my laptop, you have to travel through two doors and weave between vehicles.  I thought it would be flicked off ASAP, but I was wrong.  While looking through neighbors security footage, Teamviewer came online, then off again.  It has come online at 2AM consistently though out the week and once in the middle of the day while I was at work.  This means he is using it, not selling it like everyone has told me.  Trouble is, I can't get an IP out of the logs until I make a connection.

Things I have done:

- Changed critical passwords for websites such as Geekzone, GMail, Yahoo, FTP...etc.
- Deliberately left Facebook wide open.  If he logs in to my Facebook, I get a text and an IP address.

We did ALL the investigative work for the police.  I found the box of the laptop I purchased 4 years ago under the house with the serial number on the box!  What a life saver.  It's in the system now at least!  We handed them a vehicle description (without a pate, because the neighbors cameras suck) but managed to get one for the police the very next day through various contacts. Police matched the vehicle to our description and pate and then backed off, called the burglary squad who are now awaiting a warrant.  On Wednesday they said they will hit the house Friday or Monday.  It really didn't make much sense.  We had them red handed on camera and had all the information handed to them on a silver platter, haha!

If the police fall through, I guess I still have Teamviewer to maybe mine some information watching his movements on the internet, if I can catch him that is...Trouble is, Teamviewer makes a massive noise about someone connecting.  I would need to black his screen and disable his input to get anything.  I feel as if an IP address is false hope.  Sure if it gets far up enough through the ISP chain, something might happen, but really it's not much to go on. :(

I know firewalls, routers and all kinds of carry on might prevent this...But is there any way at all I could possibly silently install an application through the internet to follow the laptop further.  Even a key logger perhaps?  At the moment, my best option seems to simply disable his ability to use it.  It's a case of blacking his screen long enough for me to password protect it before he pulls the battery.  I may be able to auto-log in to his Facebook page to get a full name of the person using it considering he has one at all.

Any ideas?  Something I may not have thought about?  Will I have to resort to social engineering?  I understand next to nothing can be done if behind CGNAT.  I'm really grasping at straws here.

TL;DR:  Laptop stolen, no password (which I think is my saving grace here) and few leads with little police help.  Have teamviewer installed which is online, but want to silent install software on to it while it's online.  Doubt it's possible.  Maybe others with further knowledge on the subject?

Cheers,
David
