Researchers Find 36 New Security Flaws In LTE Protocol
An anonymous reader quotes a report from ZDNet: A group of academics from South Korea have identified 36 new vulnerabilities in the Long-Term Evolution (LTE) standard used by thousands of mobile networks and hundreds of millions of users across the world. The vulnerabilities allow attackers to disrupt mobile base stations, block incoming calls to a device, disconnect users from a mobile network, send spoofed SMS messages, and eavesdrop and manipulate user data traffic. They were discovered by a four-person research team from the Korea Advanced Institute of Science and Technology Constitution (KAIST), and documented in a research paper they intend to present at the IEEE Symposium on Security and Privacy in late May 2019. The Korean researchers said they found 51 LTE vulnerabilities, of which 36 are new, and 15 have been first identified by other research groups in the past. They discovered this sheer number of flaws by using a technique known as fuzzing --a code testing method that inputs a large quantity of random data into an application and analyzes the output for abnormalities, which, in turn, give developers a hint about the presence of possible bugs. The resulting vulnerabilities, see image below or this Google Docs sheet, were located in both the design and implementation of the LTE standard among the different carriers and device vendors. The KAIST team said it notified both the 3GPP (industry body behind LTE standard) and the GSMA (industry body that represents mobile operators), but also the corresponding baseband chipset vendors and network equipment vendors on whose hardware they performed the LTEFuzz tests.Read more of this story at Slashdot.
