Microsoft’s Project Silica has delivered proof of concept for its quartz glass storage by storing the 1978 movie Superman. Writing to the media is done by etching onto the quartz glass using a femtosecond laser. This new type of storage is highly efficient, can hold data for about 1000 years, and is resistant to heat and weather in general.
FoxGaurd Solutions, Monta Elkins has shown that it’s easy to plant a spy chip on various devices. In his experiment, Elkins took an ATiny85 chip smaller than a pinky fingernail coded the chip and ready it as a spy chip. He then soldered it to a motherboard of a firewall, giving the chip access to the serial port of the firewall.
He used an inconspicuous spot that required no extra wiring, also, this type of modification would not alert an administrator. Elkins said his attack could change firewall settings to offer remote access to the device, disable its security features, and give the hacker access to the device’s log of connections it sees.
What makes this proof-of-concept alarming is how easy it was to do, it’s almost impossible to spot, and how low cost it was (less than $200). With more and more of our lives living online and in the cloud, one has to wonder how secure these service providers and cloud server companies really are.
Bluetooth is a wireless technology that was created for the exchange of data between stationary and mobile devices over short distances. The first phone to feature the technology was the Sony Ericsson T39 which hit store shelves back in 2001. Over the years Bluetooth has gone through many version changes and specification improvements mainly affecting security, data speed, power efficiency, and range.
Bluetooth 5 is the latest version which first debuted in the Apple iPhone 8 and Samsung Galaxy S8. The main benefits to Bluetooth 5 are huge improvements in speed and range. Compared to Bluetooth 4.2 which has a 60 meter (196 feet) range and 1Mbps data transfer speed, Bluetooth 5 doubles the data transfer speed to 2Mbps and quadruples the range to 240 meters (787 feet).
Bluetooth 5 also features Beacon Technology, that allows businesses to send ads, coupons, and promotions to your phones and tablets. Beacon Technology can also be used to help you navigate in places like airports, hospitals, and shopping malls. Another feature that’s unique to Bluetooth 5, is the ability to play audio on two devices at the same time with no lag. An example of this, you could have two headphones connected to your tablet and stream the audio of a movie to both headphones simultaneously.
Just in case you were wondering, Bluetooth 5 is backward compatible with the previous version.
With all its features and advancements, Bluetooth 5 will play a huge role in future smart devices and smart appliances.
