A vulnerability in next-generation high-speed networks has spawned 10 different 4G LTE attacks, including location spoofing and fake messages, researchers discovered.

Experts from Purdue University and the University of Iowa released an academic paper that detailed how they created their own tool, dubbed LTE Inspector, to uncover these 4G LTE attacks. They also set up a proof-of-concept network simulation to ensure that the issues they discussed in the paper could actually take place in the wild.

The Risk of 4G LTE Insecurity

In addition to the 10 new threats discussed in the paper, the researchers confirmed nine other potential issues. The problems stem from the counter in a phone operator’s system, where a weakness in the authentication and key agreement could lead to data leaks.

According to ZDNet, the flaw could make it easier for actors to force cellphones to use 2G so they can monitor activities using so-called stingray surveillance devices. With relatively inexpensive hardware, cybercriminals could intercept calls and track where users are at a given time.

Other potential 4G LTE attacks include connecting to the network without authorized usernames and passwords, stealing a user’s identity, forcing other devices off the network and sending phony messages from someone else’s device. Bleeping Computer sketched out a scenario in which threat actors could commit a crime in the U.S. and use location spoofing to make it appear as though they were connected to a network in Europe.

Mitigating 4G LTE Attacks

The researchers didn’t provide any immediate ways to avoid or mitigate the threats covered in their paper. Help Net Security pointed out that 4G LTE attacks may lessen as the industry eventually moves to 5G, but that still leaves a lot of time for bad actors to do some potentially serious damage.

In the meantime, mobile providers would be wise to use this research as a springboard to begin investigating fixes for this flaw before cybercriminals recognize the massive opportunity in front of them.

The White House on Quantum Encryption and IoT Labels

A recent White House Fact Sheet outlined the current and future U.S. cybersecurity priorities. While most of the topics covered were in line with expectations, others drew more attention. The emphasis on critical infrastructure protection is clearly a top national priority. However, the plan is to create a labeling system for IoT devices, identifying the ones with the highest cybersecurity standards. Few expected that news. The topic of quantum-resistant encryption reveals that such concerns may become a reality sooner than…

Contain Breaches and Gain Visibility With Microsegmentation

Organizations must grapple with challenges from various market forces. Digital transformation, cloud adoption, hybrid work environments and geopolitical and economic challenges all have a part to play. These forces have especially manifested in more significant security threats to expanding IT attack surfaces. Breach containment is essential, and zero trust security principles can be applied to curtail attacks across IT environments, minimizing business disruption proactively. Microsegmentation has emerged as a viable solution through its continuous visualization of workload and device communications…

CEO, CIO or CFO: Who Should Your CISO Report To?

As we move deeper into a digitally dependent future, the growing concern of data breaches and other cyber threats has led to the rise of the Chief Information Security Officer (CISO). This position is essential in almost every company that relies on digital information. They are responsible for developing and implementing strategies to harden the organization's defenses against cyberattacks. However, while many organizations don't question the value of a CISO, there should be more debate over who this important role…

Malware-as-a-Service Flaunts Its Tally of Users and Victims

As time passes, the security landscape keeps getting stranger and scarier. How long did the “not if, but when” mentality towards cyberattacks last — a few years, maybe? Now, security pros think in terms of how often will their organization be attacked and at what cost. Or they consider how the difference between legitimate Software-as-a-Service (SaaS) brands and Malware-as-a-Service (MaaS) gangs keeps getting blurrier. MaaS operators provide web-based services, slick UX, tiered subscriptions, newsletters and Telegram channels that keep users…
