4G LTE | Breaking Cybersecurity News | The Hacker News

A group of academics from Ruhr University Bochum and New York University Abu Dhabi have uncovered security flaws in 4G LTE and 5G networks that could potentially allow hackers to impersonate users on the network and even sign up for paid subscriptions on their behalf. The impersonation attack — named " IMPersonation Attacks in 4G NeTworks " (or IMP4GT ) — exploits the mutual authentication method used by the mobile phone and the network's base station to verify their respective identities to manipulate data packets in transit. "The IMP4GT attacks exploit the missing integrity protection for user data, and a reflection mechanism of the IP stack mobile operating system. We can make use of the reflection mechanism to build an encryption and decryption oracle. Along with the lack of integrity protection, this allows to inject arbitrary packets and to decrypt packets," the researchers explained. The research was presented at the Network Distributed System Se...

If your mobile carrier offers LTE, also known as the 4G network, you need to beware as your network communication can be hijacked remotely. A team of researchers has discovered some critical weaknesses in the ubiquitous LTE mobile device standard that could allow sophisticated hackers to spy on users' cellular networks, modify the contents of their communications, and even can re-route them to malicious or phishing websites. LTE, or Long Term Evolution, is the latest mobile telephony standard used by billions of people designed to bring many security improvements over the predecessor standard known as Global System for Mobile (GSM) communications. However, multiple security flaws have been discovered over the past few years, allowing attackers to intercept user's communications, spy on user phone calls and text messages, send fake emergency alerts, spoof location of the device and knock devices entirely offline. 4G LTE Network Vulnerabilities Now, security researchers...

Everybody knows browser extensions are embedded into nearly every user's daily workflow, from spell checkers to GenAI tools. What most IT and security people don't know is that browser extensions' excessive permissions are a growing risk to organizations. LayerX today announced the release of the Enterprise Browser Extension Security Report 2025 , This report is the first and only report to merge public extension marketplace statistics with real-world enterprise usage telemetry. By doing so, it sheds light on one of the most underestimated threat surfaces in modern cybersecurity: browser extensions. The report reveals several findings that IT and security leaders will find interesting, as they build their plans for H2 2025. This includes information and analysis on how many extensions have risky permissions, which kinds of permissions are given, if extension developers are to be trusted, and more. Below, we bring key statistics from the report. Highlights from the Enterprise Browse...
