Don't use Bluetooth before installing latest updates

A Bluetooth connection can leave computers, smartphones and other devices vulnerable to security breaches, so users should quickly install any updates - or turn the function off. That's the advice of the German Federal Office for Information Security (BSI) in response to the recent "Blueborne" Bluetooth vulnerability, which is thought to have put 8 billion devices at risk. Some manufacturers have already released updates addressing the Blueborne issue, and users should refrain from using Bluetooth before installing them. However, there will probably be no security updates for devices that are no longer supported by the respective manufacturer. These are likely to remain permanently vulnerable. In addition to smartphones, tablets, notebooks and PCs using all kinds of operating systems, Bluetooth vulnerabilities can also affect devices that can be connected to the internet, such as hands-free equipment. Once infected with Blueborne malware, devices may be exposed to additional software from the internet, says the BSI. In addition, the attackers could connect devices to so-called botnets. Even devices without an internet connection, such as keyboards, can pass the malware on to other Bluetooth devices, the agency warns. According to the BSI, Bluetooth on smartphones, PCs or IT accessories should generally only be activated when really needed. This also applies to WiFi connections
