No one talks about anything else: an attack known as KRACK (Key Reinstallation AttaCK) exploits vulnerabilities in the WPA2 security protocol used by WiFi routers, putting most wireless connections to the Internet, including yours, at risk. All devices can be compromised and early research indicates that Android systems are affected, Apple, Windows, Linux, OpenBSD, MediaTek or Linksys, among others.

Although luckily has not yet revealed the exact procedure to be followed to launch this attack, after knowing the news all users are asking the same question: how to protect my WiFi network from KRANK? Here are some tips to avoid hacking your WiFi.

According to a report published by the Office of Internet Security (OSI) of the National Institute of Cybersecurity (INCIBE) to solve the problem it is necessary to update one of the parties involved in the connection process, either in the operating system of the customers or on the WiFi routers. Therefore, it is necessary to wait until device manufacturers release a patch that fixes the vulnerability in their products.

Microsoft has already addressed the issue on devices running compatible versions of Window s, according to The Verge. While the patches from other manufacturers arrive, OSI have released a series of recommendations to protect the WiFi network of KRANK that we can carry out until the patches arrive:

Do not connect to a WiFi network if it is not strictly necessary, especially if you are going to exchange personal or bank information.

Use mobile data (3G / 4G) whenever you have them, especially to make purchases or take online banking.

Stay tuned for security updates to your device’s operating system. Given that this is a major problem, it is expected that soon manufacturers and developers will release patches to address the danger.

Do not disable the router’s WPA2 option at this time, as it remains the best available option to use.

Navigate pages under the HTTPS protocol to make sure the information you are exchanging is encrypted.
