The research paper describes WiKI-Eve as “the first WiFi-based hack-free keystroke eavesdropping system.” It highlights that the attacker’s device can be as inconspicuous as a mobile device that supports monitor mode using the Wi-Fi network interface card (NIC). This means that attackers can carry out these attacks with relatively minimal equipment.
To illustrate the potential risks, the researchers set up a real-world case study. In this scenario, they were able to access a victim’s WeChat Pay information on an iPhone, implying that compromised credentials and sensitive financial data could be at risk.
