Wi-Fi eavesdropping can occur in several ways: - Unsecured Networks: Using a network without encryption makes it easy for hackers to intercept data. - Weak Encryption: Outdated encryption protocols like WEP can be easily cracked. - Man-in-the-Middle Attacks: Attackers position themselves between the user and the Wi-Fi router to intercept communications. - Evil Twin Networks: Hackers set up a fake Wi-Fi network that appears legitimate to capture data.
