KRACK WPA2 Vulnerability

KRAK WiFi Vulnerability
IT Security Expert from Belgium Mathy Vanhoef show how a black hat hacker could easily intercept and sniff data transmitted from a wireless device can be a IoT, Android or a laptop by exploiting a new vulnerability found in WiFi Authentication used in WPA2.
The hack took Mathy about 4 minutes to execute and it might be less.

KRACK vulnerability read sensitive data

Mr. Vanhoef described the vulnerability as KRACK Key Reinstallation Attack explained that attackers can exploit this vulnerability to read data being sent between a device and wireless access point it is connected to. Even if there is being utilized the strongest WPA2 WiFi encryption.

WiFi Networks by the millions vulnerable to KRACK vulnerability

The vulnerability is categorized as high severe and can be abused by black hat attackers to steal sensitive information from WiFi encrypted networks
that earlier was believed to be secure.
The information is not limited to and includes chat messages, emails, images photos, passwords, credit cards, sensitive personnel data.
The attack can exploit all modern unpatched WPA2 protected WiFi networks. This will count networks in the millions to be vulnerable if not being
secured and patched.

Not only limited to eves dropping also injection
As it is not bad enough that attackers can eves drop the traffic they can also inject and manipulate data.
This way attackers can inject Malware, Ransomware, worms into website traffic and easily infect users which believe they are secure.

What is important to know about the KRACK vulnerability?

Patches for popular linux systems are already available for download.

Some security experts claim that KRACK might be rare on Windows or iOS devices still Microsoft and Apple has released patches.

What is the real life risk to KRACK WPA2 Vulnerability?

The Security researcher has been very responsible and disclosed the vulnerability to vendors very early for them to develop patches.
The exploit tool it self has not yet by the writing of this article been released.
It might be released or leaked in the future.

Users must always use HTTPS to prevent sniffing of sensitive data even when the WPA2 encryption is being broken.
Also only visit trusted websites to prevent malware attacks.
