With more and more connected devices around us, the chance that you've been hit by an update notification is high. But what do these software updates do? How do they actually work, and why are they important?
Hardware and Software
Modern electronic devices require two main parts to function: the hardware and the software. The hardware usually refers to physical electronic pieces inside a device (usually a collection of microchips, logic gates and specialised processing chips, such as those to…

Academics have disclosed today a new vulnerability in the Bluetooth wireless protocol, broadly used to interconnect modern devices, such as smartphones, tablets, laptops, and smart IoT devices.
The vulnerability, codenamed BIAS (Bluetooth Impersonation AttackS), impacts the classic version of the Bluetooth protocol, also known as Basic Rate / Enhanced Data Rate, Bluetooth BR/EDR, or just Bluetooth Classic.
The BIAS attack
The BIAS security flaw resides in how devices handle the link key,…

We look at the recently published report on forensic science in the UK, highlight concerns about police not understanding new tech used to extract data from mobile phones; the risk of making incorrect inferences and the general lack of understanding about the capabilities of these tools.
The delivery of justice depends on the integrity and accuracy of evidence and trust that society has in it. So starts the damning report of the House of Lords Science and Technology Select…

In February 2019 Google engineers announced that they had created faster, more efficient encryption system that could function on less-expensive Android phones that were too low-powered to implement existing full-device encryption. The scheme, known as Adiantum, uses established and well-vetted encryption tools and principles. Android has required smartphones to support encryption since 2015's version 6, but low-end devices were exempt because of the performance hit. It will now be up to device…
