Hello, Andrew! Some Android smartphones have exploits sometimes and your Samsung Galaxy SIII is not an exception. As you know Android Beam is used for instant and easy content sharing between two or more NFC compatible devices. And the key here is the NFC support, because that technology uses NFC for data transmission. And the vulnerability lies in that NFC protocol. Hacker is able to replace tags and data containers in the packages, that are sent between devices via NFC and get a full access to the targeted device. So your own mobile phone is turned into GSM eavesdropping bug. In general, the whole thing looks like a huge virtual gateway, which enables hacker to connect your device remotely, copy, modify or even erase data from the physical memory of the device, access the web, intercept phone calls and messages and even dial phone numbers. In that case if he will dial his own phone number, he will be able to listen to everything that is going on around the phone itself. So we at Jammer-Store can recommend to avoid using that NFC based Android Beam technology, because it may lead to data leaks. The good news are that this technique is not that convenient, because hacker will have to remain close to the target, due to the short working range of the NFC. But if you’d like to ensure 100% safety and security of your device, you may try to turn the NFC module off, or use our special NFC jamming device. That will surely block all the hacking attempts based on exploiting that bug. Thanks for your question, I hope, I’ve managed to help.
