Firstly, the attack requires specific prerequisites, including knowledge of the target SSID and the misconfiguration of wpa_supplicant on the victim\u0027s device, which somewhat limits its widespread exploitation. Additionally, the attack vector primarily targets Enterprise networks relying on PEAP authentication, narrowing its impact compared to more widely used authentication methods. Furthermore, while the ability to bypass Phase-2 authentication poses a risk of unauthorized network access and potential data exposure, it does not directly compromise the confidentiality or integrity of sensitive information.",
