I just got a strange SMS claiming that I've registered to some weird service and based on that they took the money from my account. This was proceeded by a popup related to some mobile games while I was browsing. At no point did I register or click enter my information or telephone number.
I'm using Chrome 46.0.2490.76 and Android 4.3.0
Does anybody know what is the general technical background of this fraud and what can be done to prevent it in the future (popup blockers or similar approach?)?
