"Although 4G LTE connections are generally considered more secure, the software is not impenetrable. An international team of researchers from Ruhr-University Bochum and New York University Abu Dhabi has found vulnerabilities in the 4G LTE technology and has written a paper on its findings, but notes that exploiting the security issues in the wild would take a lot of effort and most likely target high-profile individuals like politicians or journalists. Researchers at Purdue University and the University of Iowa also published their own academic findings on 4G LTE security and privacy this year."
