A group of academics has disclosed details of over 100 security vulnerabilities impacting LTE and 5G implementations that could be exploited by an attacker to disrupt access to service and even gain a foothold into the cellular core network. The 119 vulnerabilities , assigned 97 unique CVE identifiers, span seven LTE implementations – Open5GS , Magma , OpenAirInterface , Athonet , SD-Core , NextEPC , srsRAN – and three 5G implementations – Open5GS, Magma, OpenAirInterface, according to researchers from the University of Florida and North Carolina State University. The findings have been detailed in a study titled "RANsacked: A Domain-Informed Approach for Fuzzing LTE and 5G RAN-Core Interfaces." "Every one of the >100 vulnerabilities discussed below can be used to persistently disrupt all cellular communications (phone calls, messaging and data) at a city-wide level," the researchers said. "An attacker can continuously crash the Mobility Management En...

5G is a game changer for mobile connectivity, including mobile connectivity to the cloud. The technology provides high speed and low latency when connecting smartphones and IoT devices to cloud infrastructure. 5G networks are a critical part of all infrastructure layers between the end user and the end service; these networks transmit sensitive data that can be vital for governments and businesses, not to mention individuals. As a result, 5G networks are a prime target for attackers. For this reason, cybersecurity has been a key consideration in developing the 5G standard. 5G encompasses robust security features that guarantee confidentiality, integrity, and availability of network services and user data. In this article, Seva Vayner, Product Owner of  Gcore's Edge Cloud service , gives a deep dive into five of 5 G's cutting-edge security measures. He also delves into the pivotal performance capabilities of 5G, accompanied by use cases that demonstrate how contemporary, cloud...

The problem is simple: all breaches start with initial access, and initial access comes down to two primary attack vectors – credentials and devices. This is not news; every report you can find on the threat landscape depicts the same picture.  The solution is more complex. For this article, we'll focus on the device threat vector. The risk they pose is significant, which is why device management tools like Mobile Device Management (MDM) and Endpoint Detection and Response (EDR) are essential components of an organization's security infrastructure. However, relying solely on these tools to manage device risk actually creates a false sense of security. Instead of the blunt tools of device management, organizations are looking for solutions that deliver device trust . Device trust provides a comprehensive, risk-based approach to device security enforcement, closing the large gaps left behind by traditional device management solutions. Here are 5 of those limitations and how to ov...
