KRACK: All available security updates

KRACK: On Monday morning IT around the world had a great time. The public release of an error allowing WPA2 wireless security breach has made many people run and fail.

The WPA2 error puts almost every Wi-Fi device at risk, and security experts say that its public release was the total destruction of the WPA2 security protocol.

Such as I mentioned in SecNews The error was named "KRACK" by Key Reinstallation Attack and is a major flaw in the way Wi-Fi Protected Access II (WPA2) works.

The security protocol, which is essentially an upgrade of WEP, is used to protect and secure communications between routers and devices using Wi-Fi (mobile and Internet of Things devices).

According to security researcher and academic Mathy Vanhoef, who discovered the flaw, attackers can exploit vulnerabilities to decrypt traffic, seize connections, execute attacks and monitor communications sent from a capable device. WPA2.

US-CERT has been aware of the error for several months and has informed the construction companies before the error was publicly disclosed to the public.

Who is affected:

Windows and later versions of iOS are generally unaffected, but the bug can have a serious impact on Android 6.0 Marshmallow and later.

The attack could also be catastrophic for IoT devices, as companies often fail to implement acceptable security standards or information systems in the supply chain, which has already led to the exposure of millions of vulnerable IoT devices to botnets.
