Russian security tester Timur Yunusov has found critical vulnerabilities in routers and 3G and 4G modems from Huawei, ZTE, Gemtek, and Quanta. The flaws mean attackers could completely compromise machines and intercept SMS and HTTP traffic. The research first detailed in December and showcased to hackers yesterday at the …

    No worries. We'll just patch it. oh. Wait a sec....

    Such an exploit would be highly valuable as you can make it exploit a large chunk of the market, as those chipsets all run more or less the same code, probably even the same binary code. While on PCs you are still limited by what you can do via USB, on smart phones you have direct access to the RAM of your "Application Processor".
