Threats to packet core security of 4G networks

September 28, 2017
Billions of people worldwide use IoT infrastructure. However, manufacturers of IoT devices still give short shrift to security. Mobile operators tend to be poorly prepared for modern threats. Hackers can use multiple vulnerabilities in 4G networks to conduct attacks, including interception of text and email messages, call eavesdropping, and blocking of connections. Read our report regarding the main security threats to the centerpiece of 4G (LTE) networks.

In the last few years, mobile operators have made significant CapEx investment in next-generation networks. This includes switching from the SS7 signaling protocol, which dates back to the '70s, to Diameter. But even the newer protocol contains flaws that enable an attacker to eavesdrop, track location, and commit fraud, theft, and worse. Steps must be taken to safeguard against doomsday scenarios.

SS7 exploits can turn a cell phone into an open book, allowing an attacker to read messages, track a subscriber’s location, and eavesdrop on and redirect calls. This technique is now available not only to intelligence services, but to an average hacker as well. In 2014, we described in detail security issues in signaling networks. This report contains a security analysis of SS7 networks for various operators with a subscriber base of 10 to 70 million.
