I’m sure that by now most InfoSec-lovers have heard about KRACK.
If you haven’t, check out this great explaination by a fellow StackExchanger.
It’s a new attack on WPA2 which allows for decryption and forging of packets in… Continue reading KRACK: How does a nonce reset allow for decryption?

Wi-Fi Protected Access(WPA,more commonly WPA2)handshake traffic can be manipulated to induce nonce and session key reuse,resulting in key reinstallation by a wireless access point(AP)or client. An attacker within range of an affected AP and client may leverage these vulnerabilities to conduct attacks that are dependent on the data confidentiality protocols being used. Attacks may include arbitrary packet decryption and injection,TCP connection hijacking,HTTP content injection,or the replay of unicast and group-addressed frames. These vulnerabilities are referred to as Key Reinstallation Attacks or"KRACK"attacks.

Do you think your wireless network is secure because you’re using WPA2 encryption?
If yes, think again!
Security researchers have discovered several key management vulnerabilities in the core of Wi-Fi Protected Access II (WPA2) protocol that could al… Continue reading KRACK Demo: Critical Key Reinstallation Attack Against Widely-Used WPA2 Wi-Fi Protocol
WPA2, the standard security for Wi-Fi networks these days, has been cracked due to a flaw in the protocol. Implications stemming from this crack range from decrypting Wi-Fi, hijacking connections, and injecting content. It’s fair to say, WPA2 is now Considered Harmful. The paper is available here (PDF).
This is a proof-of-concept exploit, and like all headline-making network security stories, it has a name. It’s called KRACK, for Key Reinstallation Attack. The key insight to this exploit is a vulnerability in the handshaking between routers and devices to establish a secure connection.

I have just read about a new weaknesses in the WPA2 protocol called KRACKs. The authors of the paper says that they will release scripts that can be used to test if a network is exploitable when they have time. I would like t… Continue reading Are there any detection scripts available for WPA2 Key Reinstallation Attacks (KRACKs)?
Today new research was published on vulnerabilities in wireless network security called Krack.
What are the real-world consequences of these attacks for users and owners of wireless networks, what can an attacker actually do… Continue reading Consequences of the WPA2 KRACK attack
