LTE security holes could lead to fake emergency alerts


These aren't just theoretical attacks, either. The team tested eight of the ten attacks using SIM cards from four large US carriers.

While the issues have to do with LTE itself, it is possible to fix them -- at least one of the big US carriers already has. There's still a race against time, however. You can build the necessary LTE exploit tool for as little as $1,300 using readily available parts, so a determined attacker could infiltrate a network without an abundance of resources.

This stresses the importance of testing cell standards in the real world. It's relatively easy to fix security flaws before a standard is finalized and rolls out in earnest -- it's another when it's already in use by cell carriers that may have to patch vast networks.

Yucatan is the neo-Mexican space punk racer you've been waiting for

Image
It's really been far too long since we last saw a neo-Mexican space punk racing game, hasn't it? I've certainly been waiting a fair while for one, which makes the arrival of Yucatan's demo earlier this month such a pleasant surprise; this ticks all the right boxes. The work of developer Joe Bain - with a little help from his friends - Yucatan plays like a tequilla-soaked Trackmania (and there's probably a fair dose of peyote included in that cocktail, too), a psychedelic racer that pits your gloriously proportioned ride against a series of impossibly cruel tracks. Dig down into the detail and there's a lot to like. The drifting feels fantastic, a dedicated button enabling long, lurid slides in which your softly sprung car looks like it's about to dance out of control, but which in the hand feels brilliantly pliable. The tracks, from what's in the demo, have some real teeth, featuring deathly obstacles and layouts that ask for a little reserve with th...

Rare Studio Head on Sea of Thieves Post-Launch Plans

Image
Rare has high hopes for Sea of Thieves, and according to studio head Craig Duncan, the development team intends to continue to support the game post-launch to make it "as big and successful as it can be." On the latest episode of our monthly interview show  IGN Unfiltered , Duncan said the studio "of course" has a roadmap and plan for the future of Sea of Thieves. "There's more stuff we want to add to Sea of Thieves," Duncan said, noting the team "definitely want to be reactive" to fixing any balancing issues and bugs that might arise. "Every single person I've talked to that launched a service-based game tells me, 'Hey, you think you know what you've gotta do—actually when you launch there'll be a load of different stuff,'" he explained, noting he's well aware there will probably be plenty of stuff the team wasn't aware of prior to release that they'll need to address after launch.
