Software update for Personal AXS GUARD v3.2.0
Countering Key Reinstallation Attacks
Security researchers have discovered a major vulnerability in Wi-Fi Protected Access 2 (WPA2), a type of encryption used to secure the vast majority of Wi-Fi networks.
An attacker within range of a victim can exploit this vulnerability through the use of key reinstallation attacks (KRACKs). These techniques allow attackers to read information that was previously assumed to be safely encrypted.
Sensitive information, such as credit card numbers, passwords, chat messages, emails, photos, and any other data sent over the Internet with mobile devices can be intercepted and stolen.
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.
What should you do ?
Wi-Fi users should immediately update their Wi-Fi-enabled devices as soon as a software update is made available. Wi-Fi enabled devices are anything that connects to the Internet — from laptops, tablets, and smartphones to other smart devices such as wearables and home appliances.
