Games in Google+

The launch of games on Google+ is no surprise. Back in June, a reference to “Google+ Games” appeared in Google+ code. Google has been taking its time to make sure Google+ is fully functional before wide release and before it starts accepting branded profiles, but gaming is clearly a big step toward building a viable competitor to Facebook.

Hackers break into Subaru Outback via text message


We've already seen SCADA systems controlled by Google Search, and now the Black Hat Technical Security Conference is offering up yet another slice of cringe-inducing hacker pie. A pair of pros from iSec Partners security firm was able to unlock and start the engine of aSubaru Outback using an Android phone and a process they call war texting. By setting up their own GSM network, they were able to snatch up password authentication messages being sent from server to car, allowing them the option to ride off in a brand new crossover. Apparently, your car isn't the only thing in danger of a war-texting takeover, however, as the team says there are a slew of devices and systems, accessible over telephone networks, that are vulnerable to similar attacks, including A-GPS tracking devices, 3G security cameras, SCADA sensors -- and thus the power grid and water supply -- home automation, and urban traffic control systems. Somehow this group of otherwise innocent looking New York textersappears a whole lot more sinister now.
