Just a few days ago, a series of vulnerabilities in the security of WiFi networks known as KRACK, an acronym for key reinstallation, came to light. The WPA2 security protocol, used to protect the vast majority of wireless connections, had been hacked, compromising the WiFi network traffic security and exposing the personal information of millions of users.
The weakness, identified by the researcher Mathy Vanhoef, could affect 41% of devices that work with an Android operating system, as pointed out by McAfee, in a statement. With the emergence of these new threats, cybercriminals could take advantage of vulnerabilities in the security of wireless networks to intercept access credentials, credit card data, emails or personal information.
In addition, and as explained by the security company, they could also inject “ransomware” -“malware” that encrypts computers and asks for a ransom- or other malicious content on a website, which means that even a reliable website could be offering a link or ad that actually leads to a program or other malicious content.
Keep IP address hidden
In an increasingly connected world, users need to feel protected. Not in vain, once a cybercriminal has access to a wireless network, the possibilities of “hacking” are practically endless. But how can users protect themselves from these attacks and connect to the network securely? McAfee advises users to keep their IP address hidden while connecting to public or open Wi-Fi networks, as this will allow both your location and your information (bank details, passwords, credentials, etc.) to remain secure.
The company also stresses the importance of updating devices. Users should make sure to install security updates on their devices. In this way, they can avoid, as far as possible, any vulnerability in the systems.
Update the firmware of the router
The router is the most important element to protect the wireless network. However, this update largely depends on how quickly device manufacturers and software developers release a patch. Therefore, McAfee emphasizes that it is recommended to check the respective device manufacturer’s website for details and patch status to protect against KRACK.
Whether a virtual private network can be used
It is also convenient to use VPN networks. If the user needs to connect to a public network, they can use a virtual private network (VPN). A VPN will keep information private and ensure that data goes directly from the device to wherever it connects. It is essential to install security on the devices. Having a comprehensive security solution can help keep your devices safe from viruses and other unwanted malware.
The appearance of this new vulnerability in Wi-Fi networks that use WPA2 security encryption reinforces the idea that cybercriminals are becoming more creative and use more sophisticated attack methods to try to compromise systems. For this reason, and as the company points out, users must be prepared to counteract these threats and guarantee the security of all their devices.
