2️⃣DoS- Exploiting Countermeasures (MIC failure)

One countermeasure against DoS attacks is called "MIC failure" (Message Integrity Code failure). MIC is a form of cryptographic protection used in Wi-Fi networks, particularly those secured with WPA (Wi-Fi Protected Access) or WPA2 (Wi-Fi Protected Access 2) protocols. MIC ensures that data packets transmitted over the wireless network are not tampered with or altered in transit.

In the context of DoS attacks, a MIC failure can occur when the integrity of the data packets is compromised. Attackers might attempt to exploit vulnerabilities in the cryptographic algorithms or implementation flaws in the Wi-Fi access points or clients to manipulate the data packets in such a way that they pass the integrity check but contain malicious content.

If an attacker has forged a victim user with two MIC Failure Reports, then this user is blocked for 1 minute.

If the attacker continues to send invalid attempts, the victim user will be banned.
