According to Reuters, the German Security Research Labs discovered a vulnerability in the widely used wireless technology which could potentially give remote access to malicious hackers to hundred of thousands of GSM devices in a short timeframe giving the possibility to make rogue phone calls and send fraudulent text messages.
This was done in the past on a limited number of devices, but now this could be possible on a larger scale due to the fact that 80% of mobile market today uses the WiFi technology, said Karsten Nohl, head of Germany’s Security Research Labs to Reuters.
“We can do it to hundreds of thousands of phones in a short timeframe,” Nohl told Reuters in advance of a presentation at a hacking convention in Berlin on Tuesday, December 26th.
Mobile network is by far the weakest part of the mobile ecosystem, even when compared to a lot attacked Android or iOS devices,” he said.
The study was conducted by the German Security Research Labs on operators in Austria, Belgium, the Czech Republic, France, Germany, Hungary, Italy, Morocco, Slovakia, Switzerland and Thailand.
