Vulnerabilites in the 'Diameter' signalling protocol used to authenticate and authorize messages and information distribution in 4G networks leave them vulnerable to attack. Researchers at Positive Technologies replicated the actions of threat actors and their attempts to infiltrate mobile networks were 100 percent successful. They also discovered that the biggest threat was denial of service attacks. This means 5G networks built on top of previous generation networks will also inherit the same threats -- such as tracking user location, obtaining sensitive information and in some cases downgrading users to insecure 3G networks. This is because the first generation of 5G… [Continue Reading]
