Data transfer between smart phones and smart watches are not safe

Security researchers warn that as more and more devices start to interact with Smartphones, text messages, calendar entries, moving data to other sensitive user information may have been cracked by hackers.

This is because most of the smart watch with six digit password for Android smartphones ... Encrypted connection between cell phones and smart devices that only 1 million code combinations available, so passwords are easy to hack brute force near.

Researchers at security firm Bitdefender had a pair and carrying Android Google Nexus 4 l preview system pairing Samsung Smart Watch Gear Live hack demo. Using ready-cracking tools, they found the password protected Bluetooth connection between two devices is easy to brute force. Once the crack they can monitor the transmission of information between watches and mobile phones.

Researchers brute Bluetooth connection after intercepting a message

This discovery is not surprising. Six-digit password that only 1 million combinations. Safety engineers have long known that it is difficult to prevent the hacker from cracking. However, this study is still important, because studies of the timing is very important. With so many new smart watch and other wearable device appears, become more and more sensitive data for transmission via Bluetooth. Smart device manufacturers can device before it became popular to create a secure communication channel.

It is unfortunate, some obvious fixes could cause inconvenience to users, it is a bitter pill for the producers. For example, the most obvious remedy in smart devices before pairing, enter a passcode, but given that most limit wearable device keyboard, so users will be discontent. Another possible remedy is when you make matches, relied on NFC pass password to the smart watch, but it will increase the cost of equipment and complexity. Third option is run on the second layer of encryption programs on mobile phones and watches enhanced Bluetooth encryption. Sure, there are other fixes, hope engineers begin to find out more about the method.
