Researchers have found a vulnerability with the 5G network months before the high-speed protocol is set to roll out. In a paper detailing privacy threats for 3G, 4G, and 5G, researchers from the Technical University in Berlin, ETH Zurich and SINTEF Digital Norway found a vulnerability affecting Authentication and Key Agreement (AKA) -- which is how your phone securely communicates with cellular networks. The new vulnerability allows potential data thieves to steal information from 5G airwaves, such as a number of calls and text messages sent, according to ZDNet. The advent of 5G is supposed to bring supercharged speeds to mobile devices, and low latency, opening the door for tech innovations like self-driving cars and virtual reality. The new technology is also supposed to bring in a new level of security, as government agencies use International Mobile Subscriber Identity, or IMSI catchers to impersonate cell towers and spy on phones with older connections. IMSI catch...

Apple’s clash with Facebook and Google: What you need to know

If you want a sense of how much power Apple holds over Silicon Valley, take a look at what the iPhone maker did to Google and Facebook this week. On Wednesday, Apple yanked enterprise certificates -- digital signatures that both the tech giants used to run software on iPhones and iPads. That shut down internal apps employees at the companies used to communicate with their coworkers, find shuttle buses and test new features that could eventually be released to the public. It proved to be more a show of power than long-term punishment. Apple, which did not respond to comment, restored both companies' certificates by Thursday. Google said its internal apps are back up and running. Facebook confirmed Apple restored its certificates but said it did not have any new information to share. Here's what you need to know. What's going on? The spat started after TechCrunch reported that Facebook had taken advantage of an Apple program that lets companies design apps for p...

Huawei illuminates its foldable phone in MWC 2019 teaser photo

We've known for a while that Huawei's planning to unveil its first foldable phone at MWC 2019, joining the minor parade led by the Samsung Galaxy X (or whatever it's called), but this is our first peek at what Huawei's foldable effort will look like. The company posted a teaser photo (or render) on Twitter to promote its Mobile World Congress 2019 press conference, showing a silhouette of the phone illuminated by the colors coming off the screen and asking, "Are you ready to reveal the unprecedented?" While it looks cool, the shape of the hinge may augur that it won't fold flat. But we do know that it'll be 5G-ready, as the company announced in late January. Foldable designs let manufacturers expand a handset's screen size while keeping the device compact enough to carry it the way we've become accustomed to. The radical new design is also viewed as a compelling way to encourage upgrading in a mature market, in which we're holding...
