Im pretty sure that most of you guys know about the recent phone scam which is circulating right now. They have been calling a lot of people in countries such as Germany, Sweden, the UK and probably more. The scam is pretty simple; they pretend to be from a department within Microsoft which has received indications that your computer is infected with some malware. They will then offer (for free) to verify if this is the case. If the victim agrees on this, they will ask the victim to perform certain actions, and also type certain commands, which will trick a non-experienced used that the output is actually showing that the computer is infected.
I just want to mention that there is no such department at Microsoft, and they would never call up customers offering this. So if you ever get a call from Microsoft stating that there are some indications that your computer is broken or infected – please hang up!
Well, they have called me several times, and finally Ii got fed up with this and started to play along. At the same time I had my virtual machines running and was recording everything that they were doing. The goal was to find out who they were and exactly what the scam was. Luckily I was able to get hold of information such as their internal IP addresses, the PayPal accounts used to wire money and the numbers they are calling from.
