Bluetooth security gap – billion devices endangered

Useful for smartphone users. However, the technology has a serious safety gap. Billions of devices could be affected, experts estimate. The Federal Office for Information Security (BSI) also warns against the dangerous nature of the vulnerability because it could cause serious damage to the user: “This includes spying out communications, running trojans, or copying stored data.”

Two billion devices with Android, two billion with Windows and around one billion Apple devices are to be affected. “All iPhone, iPad, and iPod touch devices with iOS 9.3.5 and lower are affected by the vulnerability. We recommend to play the latest iOS, “the security experts from Armis write. Android is even worse: The experts say, all Android smartphones, tablets and other Android-based devices such as Fitnesstracker are affected. Many vendors have already responded and released updates to close the vulnerabilities. Microsoft has refused on Tuesday. Apple products with updated operating system should not be affected. Before the security investigators publicly made the damage site public, the affected companies were informed.

“Unfortunately, a large number of devices are not supplied with updates because they are either no longer supported by the manufacturer or can not be connected to the Internet,” says a spokesman for BSI from Bonn. For example, headsets or Bluetooth speakers. The Federal Office recommends: Bluetooth should only be used in exceptional cases and otherwise switched off in principle. A problem with Bluetooth connections is that they are used particularly frequently in the spreading “Internet of Things”. For example, when objects communicate at home, but also when fitness bracelets send data. It is precisely for this reason that experts like Wojzechowski advise to regular updates: “The most up-to-date software to install is one of the most effective measures that can be taken.”
