Of all these attacks, the AWDL vulnerabilities that allow user tracking are the most concerning. Using the vulnerabilities, the researchers were able to obtain information from an AWDL connection like device hostname, real MAC address even with MAC address randomization turned on, the AP the device is connected to, as well as device class and version of the AWDL protocol. All these details are sufficient enough to lead to tracking of users, and if linked with data from online advertisers and analytics utilities, devices could be associated with their owners.
