4G LTE exploit | Breaking Cybersecurity News | The Hacker News

A team of academic researchers—who previously made the headlines earlier this year for uncovering severe security issues in the 4G LTE and 5G networks —today presented a new attack called ' ReVoLTE ,' that could let remote attackers break the encryption used by VoLTE voice calls and spy on targeted phone calls. The attack doesn't exploit any flaw in the Voice over LTE (VoLTE) protocol; instead, it leverages weak implementation of the LTE mobile network by most telecommunication providers in practice, allowing an attacker to eavesdrop on the encrypted phone calls made by targeted victims. VoLTE or Voice over Long Term Evolution protocol is a standard high-speed wireless communication for mobile phones and data terminals, including Internet of things (IoT) devices and wearables, deploying 4G LTE radio access technology. The crux of the problem is that most mobile operators often use the same keystream for two subsequent calls within one radio connection to encrypt th

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
