'4G completely drain '

- Chinese hacker Wanqiao Zhang showed how almost all drain the 4G traffic is at a cybersecurity conference in Australia. According to The Register Zhang demonstrated how they can redirect 4G traffic and therefore can eavesdrop.

And although 4G networks themselves are pretty safe, there is a weak spot in according to Zhang. For example, 4G networks automatically switch to other wireless technologies- 2G as- in the event that a network is overloaded, for example. That transition could be exploited by attackers to take over 4G phones.

Not only can be monitored so all traffic, is also possible to call or send messages on behalf of others.
