Researchers from Boston University (BU) have detected a vulnerability in several high-profile Bluetooth devices that could allow third parties to determine their location and other sensitive information. In the wrong hands, this information can be used to track or control every step of a user. This is especially worrying, given that basically everyone is carrying a device that supports the technology Bluetooth.
How does this vulnerability allow hackers get the user's location?
A The vulnerability has to do with the way that devices with Bluetooth technology connect. In this relationship, one device serves as a central connection and the other plays a peripheral role. The peripheral device sends a signal that contains a unique address (similar to an IP address) and data about the connection. Most devices produce a random address that automatically reconfigures itself periodically. This means protecting users ’privacy, but BU researchers found that using an“sniffer"Open source, they could identify Bluetooth connections even when their addresses were changed
Although vulnerability does not allow hackers have access to users personal data, it can be used to track Bluetooth devices. Device users with the system Android you can rest assured about it. Researchers say that devices Android don't seem to be vulnerable, but devices that use Windows 10 e iOS can be tracked.
