What You Should Know About the ‘KRACK’ WiFi Security Weakness

Researchers this week published information about a newfound, serious weakness in WPA2 -- the security standard that protects all modern Wi-Fi networks. What follows is a short rundown on what exactly is at stake here, who's most at-risk from this vulnerability, and what organizations and...

Multiple Vulnerabilities in Wi-Fi Protected Access and Wi-Fi Protected Access II

On October 16, 2017, a research paper with the title “Key Reinstallation Attacks: Forcing Nonce Reuse in WPA2” was made publicly available. This paper discusses seven vulnerabilities affecting session key negotiation in both the Wi-Fi Protected Access WPA and the Wi-Fi Protected Access II WPA2...

New KRACK Attack Against Wi-Fi Encryption

Mathy Vanhoef has just published a devastating attack against WPA2, the 14-year-old encryption protocol used by pretty much all wi-fi systems. Its an interesting attack, where the attacker forces the protocol to reuse a key. The authors call this attack KRACK, for Key Reinstallation Attacks This ...

CVE-2017-13084

Wi-Fi Protected Access WPA and WPA2 allows reinstallation of the Station-To-Station-Link STSL Transient Key STK during the PeerKey handshake, allowing an attacker within radio range to replay, decrypt, or spoof frames...

KRACK Attack Devastates Wi-Fi Security, WPA 2 Protocol

A devastating weakness plagues the WPA2 protocol used to secure all modern Wi-Fi networks, and it can be abused to decrypt traffic from enterprise and consumer networks with varying degrees of difficulty. Not only can attackers peek at supposedly encrypted traffic to steal credentials and payment...

CVE-2017-13079

CVE-2017-13082

A new exploitation technique called key reinstallation attacks KRACK affecting WPA2 has been discovered. A remote attacker within Wi-Fi range could exploit this attack to decrypt Wi-Fi traffic or possibly inject forged Wi-Fi packets by reinstalling a previously used pairwise key PTK-TK by...

CVE-2017-13086

Wi-Fi Protected Access WPA and WPA2 allows reinstallation of the Tunneled Direct-Link Setup TDLS Peer Key TPK during the TDLS handshake, allowing an attacker within radio range to replay, decrypt, or spoof frames...

CERT/CC Reports WPA2 Vulnerabilities

CERT Coordination Center CERT/CC has released information on Wi-Fi Protected Access II WPA2 protocol vulnerabilities. Exploitation of these vulnerabilities could allow an attacker to take control of an affected system. The vulnerabilities are in the WPA2 protocol, not within individual WPA2...

CVE-2017-13087

Wi-Fi Protected Access WPA and WPA2 that support 802.11v allows reinstallation of the Group Temporal Key GTK when processing a Wireless Network Management WNM Sleep Mode Response frame, allowing an attacker within radio range to replay frames from access points to clients...

CVE-2017-13082

CVE-2017-13081

Wi-Fi Protected Access WPA and WPA2 that supports IEEE 802.11w allows reinstallation of the Integrity Group Temporal Key IGTK during the group key handshake, allowing an attacker within radio range to spoof frames from access points to clients...

KRACK Demo: Critical Key Reinstallation Attack Against Widely-Used WPA2 Wi-Fi Protocol

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 allow an attacker to hack into your Wi-Fi network a...

Over The Air - Vol. 2, Pt. 3: Exploiting The Wi-Fi Stack on Apple Devices

Posted by Gal Beniamini, Project Zero In this blog post we’ll complete our goal of achieving remote kernel code execution on the iPhone 7, by means of Wi-Fi communication alone. After developing a Wi-Fi firmware exploit in the previous blog post, we are left with the task of using our newly...

Microsoft Issues Patches For Severe Flaws, Including Office Zero-Day & DNS Attack

As part of its "October Patch Tuesday," Microsoft has today released a large batch of security updates to patch a total of 62 vulnerabilities in its products, including a severe MS office zero-day flaw that has been exploited in the wild. Security updates also include patches for Microsoft Window...

Apple: Multiple Race Conditions in PCIe Message Ring protocol leading to OOB Write and OOB Read(CVE-2017-7115)

Broadcom produces Wi-Fi HardMAC SoCs which are used to handle the PHY and MAC layer processing. These chips are present in both mobile devices and Wi-Fi routers, and are capable of handling many Wi-Fi related events without delegating to the host OS. On iOS, the "AppleBCMWLANBusInterfacePCIe"...
