Key Reinstallation Attack (KRACK)

A security flaw in WPA2 that allows attackers to intercept and manipulate Wi-Fi traffic.

Understanding:

KRACK is an attack that exploits vulnerabilities in the WPA2 Wi-Fi protocol, allowing attackers to intercept and decrypt wireless communications.

Common Applications and Use Cases:

Intercepting Encrypted Wi-Fi Traffic – Attackers eavesdrop on network communications.
Man-in-the-Middle (MitM) Attacks – Injecting malicious packets into Wi-Fi traffic.
Credential Theft & Session Hijacking – Stealing authentication tokens from victims.

Best Practices and Security Considerations:

Use WPA3 Encryption – More resistant to KRACK attacks.
Apply Firmware & Software Patches – Many vendors have released fixes.
Use a VPN on Public Wi-Fi – Encrypts traffic to prevent interception.
