Billing bypass and fraud on LTE networks

[damage]

Hi everyone,
Im new in this forum so this is my first post. Im opening this thread (and correct me if this not the right place) to hear from the expert on this matter what are the actual frauds/billing bypass that are you seeing in the mobile networks.
Actually i know there are some tools that encapsulate TCP traffic over UDP (wich is not chargeable content) and also, there are method to use TXT record in DNS querys to encapsulate HTTP traffic.

Most operators just monitor not chargeable content metrics in order to identify fraud, but there is a automated way to do this? what is your experience?

Thanks

You can learn about dns tunneling here:

(b) https://community.infoblox.com/t5/Co...orks/ba-p/3664

This technique is very common on 3G/LTE network to bypass billing controls. despite is _very_ slow to transmit TCP over UDP, the fraud is successfull.
