If you are a happy owner of Android Smartphone based on Exynos 4210/4412 processor your Smartphone has a critical exploit, which can be used against you.The market of mobile devices is growing really fast and we use those every day. Cell phones, tablets and laptops are important parts of our lives nowadays. We use them not only for communications, but for data transmission and processing. Also many people are getting to use those devices for their business affairs. That’s not surprising, because modern Smartphones are really powerful and their portability makes them to be just a perfect asset for business. But we should pay attention that most of mobile phones are not meant for this, that’s why they may have some security issues, which may become critical to a mobile device owner’s security.
Exynos 4210/4412 Critical Exploit
We should pay more attention to a security of our mobile devices if we would like to use them for really important things. As for an example of such issues we can mention the recent issue regarding Android phones based on Exynos processing unit. Actually mobile processors Exynos 4210 and 4412 can be dangerous. The file that works with physical memory that is at dev/exynos-mem has critical vulnerabilities, using which someone may gain full access to your device. That exploits works for Samsung Galaxy S III, Samsung GALAXY Note II and other mobile devices that are based on Exynos 4210 and 4412 and run Android OS. Actually we are talking about the root access. After that, that hacker is able to do everything with your mobile device.
So, just imagine what a hacker can do if he will gain a root access to all your physical memory. That opens a wide variety of options. It will be possible to steal your data from the mobile device, or simply wipe it out, turning your phone into a useless brick. But there could be more sophisticated ways to use that root access. First one is to use it to steal money from your account by sending text messages or dialing some phone numbers. Or that evildoer may try to install some kind of tracking app on your phone to have the possibility to monitor your location. The most skilled hackers may even try to configure a digital gateway between your device and their equipment. In that case they will be able to eavesdrop your calls and even to listen to everything that is around your phone by making it to dial their hardware. So in that case your own mobile phone will turn into tracking and eavesdropping bug.
You should know that’s not the only example of such exploits. NFC compatible phones running on Android OS also had some issues with that module. It enabled evildoers to upload malicious applications to their cell phones in a background mode. Devices form Apple Inc. were vulnerable to a specific code, which could run on their device, while they were surfing the net. Full access to the Smartphone was granted too.
We at Jammer-Store Company are really concerned about that bug. We’ve checked that XDA developers’ forum provided a non-official fix for that vulnerability, but major companies are silent. So while they develop a fix or a patch it will be cool to have some additional means of security. First of all try to install an up-to-date anti-virus application. Try to avoid installing applications from suspicious websites, use Play Market. To enhance your device’s security avoid connecting to an unknown or public Wi-Fi hotspots, so it will be hard for a hacker to connect to your mobile device.
In some cases you’d probably need 3G/4G signal jammers to block internet connection of your Smartphone. That can be used as short term security booster. But you should be really careful with those devices because there are other people around and they would not be really happy if you will block their connections!
