U.S. cybersecurity and intelligence agencies have  released  a set of recommendations to address security concerns with 5G standalone network slicing and harden them against possible threats. "The threat landscape in 5G is dynamic; due to this, advanced monitoring, auditing, and other analytical capabilities are required to meet certain levels of network slicing service level requirements over time," the U.S. Cybersecurity and Infrastructure Security Agency (CISA) and the National Security Agency (NSA)  said . 5G is the fifth-generation technology standard for broadband cellular networks, offering increased data speeds and lower latency. Network slicing is an architectural model that allows mobile service providers to partition their network up into several independent "slices" in order to create virtual networks that cater to different clients and use cases. The latest advisory builds upon guidance  previously issued  by the agencies in December 2022, warn...

Inadequate implementation of telecom standards, supply chain threats, and weaknesses in systems architecture could pose major cybersecurity risks to 5G networks, potentially making them a lucrative target for cybercriminals and nation-state adversaries to exploit for valuable intelligence. The analysis, which aims to identify and assess risks and vulnerabilities introduced by 5G adoption, was published on Monday by the U.S. National Security Agency (NSA), in partnership with the Office of the Director of National Intelligence (ODNI) and the Department of Homeland Security's (DHS) Cybersecurity and Infrastructure Security Agency (CISA). "As new 5G policies and standards are released, there remains the potential for threats that impact the end-user," the report  said . "For example, nation states may attempt to exert undue influence on standards that benefit their proprietary technologies and limit customers' choices to use other equipment or software." S...

Cybersecurity researchers have disclosed a new security vulnerability in Qualcomm's mobile station modems (MSM) that could potentially allow an attacker to leverage the underlying Android operating system to slip malicious code into mobile phones, undetected. "If exploited, the vulnerability would have allowed an attacker to use Android OS itself as an entry point to inject malicious and invisible code into phones, granting them access to SMS messages and audio of phone conversations," researchers from Israeli security firm Check Point  said  in an analysis published today. The heap overflow vulnerability, tracked as CVE-2020-11292 , resides in the QMI voice service API exposed by the modem to the high level operating system, and could be exploited by a malicious app to conceal its activities "underneath" the OS in the modem chip itself, thus making it invisible to the security protections built into the device. Designed since the 1990s, Qualcomm  MSM  chip...

Is Managing Customer Logins and Data Giving You Headaches? You're Not Alone! Today, we all expect super-fast, secure, and personalized online experiences.

If you're dealing with logins, data privacy, bringing new users on board, or building digital trust, this webinar is for you . Join us for " Navigating Customer Identity in the AI Era ," where we'll dive into the Auth0 2025 Customer Identity Trends Report . We'll show you what's working, what's not, and how to tweak your strategy for the year ahead. In just one session, you'll get practical answers to real-world challenges like: How AI is changing what users expect – and where they're starting to push ba...

New research into  5G architecture  has uncovered a security flaw in its network slicing and virtualized network functions that could be exploited to allow data access and denial of service attacks between different network slices on a mobile operator's 5G network. AdaptiveMobile shared its findings with the GSM Association (GSMA) on February 4, 2021, following which the weaknesses were collectively designated as CVD-2021-0047. 5G is an evolution of current 4G broadband cellular network technology, and is based on what's called a service-based architecture (SBA) that provides a modular framework to deploy a set of interconnected network functions, allowing consumers to discover and authorize their access to a plethora of services. The network functions are also responsible for registering subscribers, managing sessions and subscriber profiles, storing subscriber data, and connecting the users (UE or user equipment) to the internet via a base station (gNB). What's more, ...

As 5G networks are being gradually rolled out in major cities across the world, an analysis of its network architecture has revealed a number of potential weaknesses that could be exploited to carry out a slew of cyber assaults, including denial-of-service (DoS) attacks to deprive subscribers of Internet access and intercept data traffic. The findings form the basis of a new " 5G Standalone core security research " published by London-based cybersecurity firm Positive Technologies today, exactly six months after the company released its " Vulnerabilities in LTE and 5G Networks 2020 " report in June detailing high impact flaws in LTE and 5G protocols. "Key elements of network security include proper configuration of equipment, as well as authentication and authorization of network elements," Positive Technologies said. "In the absence of these elements, the network becomes vulnerable [to] subscriber denial of service due to exploitation of vulnera...
