What is it about?
This paper investigates the security vulnerabilities in mobile identities when using WiFi services provided by mobile network operators. The authors identify several attacks that can be carried out on commonly used authentication protocols, allowing an attacker to obtain and track a user's International Mobile Subscriber Identity (IMSI) while connected to WiFi. These attacks are made possible due to a lack of adequate privacy protection measures, which are further worsened by preconfigured device profiles. We detail a range of potential countermeasures to tackle these issues to ensure that privacy is better protected in the future
