Kracrack attack break all WI-FI security (WPA2) Wi-Fi Protected Access






















Kracrack attack break all WI-FI security (WPA2) Wi-Fi Protected Access

A researcher’s discovered vulnerabilities found like 2000, see Wi-Fi protected found vulnerabilities list down below .An attacker within range of a victim can exploit these weaknesses using key reinstallation attacks (KRACKs). 

Concretely, attackers can use this novel attack technique to read information that was previously assumed to be safely encrypted. This can be abused to steal sensitive information such as credit card numbers, passwords, chat messages, emails, photos, and so on.

The attack works against all modern protected Wi-Fi networks. Depending on the network configuration, it is also possible to inject and manipulate data. For example, an attacker might be able to inject ransomware or other malware into websites.
The weaknesses are in the Wi-Fi standard itself, and not in individual products or implementations. Therefore, any correct implementation of WPA2 is likely affected. To prevent the attack, users must update affected products as soon as security updates become available. Note that if your device supports Wi-Fi, it is most likely affected. During our initial research, we discovered ourselves that Android, Linux, Apple, Windows, OpenBSD, MediaTek, Linksys, and others, are all affected by some variant of the attacks. For more information about specific products, consult the database of CERT/CC, or contact your vendor.

The research behind the attack will be presented at the Computer and Communications Security (CCS) conference, and at the Black Hat Europe conference. Our detailed research paper can already be downloaded.

Krackattack demonstration its proof-of concept the attacker is he can easy us able to decrypt all data that the victim transmits information’s. 4-way handshake, group key handshake, or Fast BSS Transition (FT) handshake is vulnerable to key reinstallation attacks. These scripts will be released once we have had the time to clean up their usage instructions. POC that exploits the all zero key re-installation resent in certain Android and Linux devices. This script is the one that we used in the demonstration video  on youtube.
