Key Reinstallation Attack (KRACK)
Key Reinstallation Attack (KRACK) is a security vulnerability that affects Wi-Fi networks. It allows attackers to steal sensitive information transmitted over wireless networks, such as passwords, credit card numbers, and other personal data.
The KRACK attack exploits a weakness in the Wi-Fi protocol itself, rather than in individual products or devices. This means that any device that uses Wi-Fi is potentially vulnerable, regardless of its manufacturer or operating system.
The way the attack works is by tricking a device into reinstalling an already-used encryption key. This can allow the attacker to decrypt and intercept network traffic, including sensitive information that is supposed to be protected by encryption.
In order to protect your devices from KRACK, it is important to keep them up-to-date with the latest security patches. You can also make sure to use secure connections and avoid connecting to public Wi-Fi networks that are not secured with WPA2 encryption.
Overall, KRACK is a serious security vulnerability that highlights the importance of staying vigilant about online security and taking steps to protect your personal data from attackers.
