How mobile operators analyze our data
Mobile operators receive a lot of data and metadata, from which you can learn a lot about the life of a single subscriber. And having understood how this data is processed and stored, you will be able to track the entire chain of information passing from the call to debiting money. If we talk about the internal intruder model, then the possibilities are even more enormous, because data protection is not included in the tasks of the mobile operator's pre-billing systems at all.
