According to foreign media reports, researchers at Purdue University and the University of Iowa after research and investigation found a large number of new vulnerabilities in the 4G LTE network, they can peeping user information, tapping their phones, making the device offline or even false Emergency alert. The researchers described 10 attacks in detail in their response report. These vulnerabilities can initiate authentication relay attacks by emulating the identities of existing users.
