New SecurityGen study highlights hidden threat to 5G mobile networks from GTP-based cyberattacks
LONDON — Mobile operators need to reassess security vulnerabilities in the key GPRS Tunnelling Protocol (GTP) and bolster GTP security within their networks as they continue to invest in and roll out 5G, according to a new study by SecurityGen.
SecurityGen’s latest report, titled “GTP vulnerabilities: A cause for concern in 5G and LTE networks,” is based on 150 telecom security assessments of 39 live mobile networks during 2022 and 2023. It found that nearly 77% of networks had no cybersecurity measures in place against GTP-based attacks. Only 23% had a high level of cybersecurity measures to keep successful GTP-based test attacks to a minimum.
