5G: marginally Faster But No More Secure nothing is fixed, it's a weaponized system.
It was hoped that 5G networks would prove more resilient to ISMI attacks than their forebears, but as a group of security researchers explained at a black hat conference in Las Vegas last week,
5G “was developed to fix the issues that allow fake base station attacks…But we found that actually 5G does not give the full protection against these fake base station attacks.”
One trick that Stingray-like devices can perform is downgrading the security setting of 5G devices, assigning them low-level security intended for basic IoT devices, leaving them dangerously exposed.
Security concerns surrounding 5G aren’t just limited to MITM attacks, either, it should be noted: fears over government-led espionage have sparked a furious debate over-reliance on Huawei to provide wireless infrastructure. Despite having been named a US security threat in May, the Chinese company is poised to dominate the UK’s 5G roll-out, with the four leading wireless operators planning to use Huawei components.
As the Guardian notes, “5G will have more sensitive information accessed closer to the edge – or the non-core – of the network, which Huawei’s critics could flag as a concern.”

For every security hole that a new technology claims to patch, it introduces another one. It has been this way since time immemorial, and the introduction of 5G will be no different. For enterprises intent on keeping their company secrets a secret, avoiding doing business over cellular networks altogether is impractical in today’s hyper connected, remote working age. Acknowledging the severity and scope of threats doesn’t mean being resigned to them, however. There are practical precautions that enterprises can take to limit their exposure, from enforcing strong authentication to securing devices with cellular protection that can detect and block threats. There’s no such thing as perfect security in an imperfect world.
