IMP4GT Vulnerability in LTE Threatens Almost All Modern Smartphones
Experts from Ruhr University reported an IMP4GT (IMPersonation Attacks in 4G NeTworks) problem. Modern LTE-enabled devices are vulnerable to IMP4GT, therefore, it threatens almost all smartphones, tablets, and IoT devices. A bug allows simulating another user’s operator’s network, which means an attacker will be able to issue paid subscriptions at the expense of other people… Continue reading IMP4GT Vulnerability in LTE Threatens Almost All Modern Smartphones
