How To Deal With The WPA2 Wi-Fi Network Vulnerability?

We all know that our Wi-Fi network is safe if the WPA2 type of encryption encrypts it. But, it is not the case anymore. The security researchers have recently discovered a crucial Wi-Fi Protected Access 2 (WPA2) network vulnerability. So, today we are going to discuss how to deal with such vulnerability in network.

WPA2 is a Wi-Fi network security key that offers a unique encryption code to the clients connected to the Wi-Fi network. Network encryption is necessary to keep the digital data secure from any type of intrusion or cyber attack. It works as a secret code that you can only decipher if you have the key. But now, the researchers have found out that the WPA2 encryption also has some network vulnerability, which the cybercriminals can take advantage of and get their hands on the sensitive information of the wireless client.

What Is WPA2 Wi-Fi Network Vulnerability?

The vulnerability that we are talking about here is known as KRACKs (Key Reinstallation AttaCKs). It is not a single network vulnerability; it is a group of multiple vulnerabilities. If the hackers successfully exploit these vulnerabilities, then they can get access to the Wi-Fi network and steal and intercept all the data transmitted over the network.

In such a situation, all the crucial data which you store on your connected device as well as transmit using the Wi-Fi network becomes vulnerable like:

  • Social Security Number,
  • Bank information,
  • Credit and debit card details,
  • Driver’s license number, etc.

All this digital personal information can be used by adversaries to commit identity thefts and other types of fraud.

Which Operating Systems Will be Affected?

According to the researchers who found out this vulnerability, if a cyber attack is initiated, it would be “especially catastrophic” against the wpa_supplicant version 2.4 and above. It is the Wi-Fi client that is usually used on the Linux operating system and Android 6.0 and above.

How To Deal With This Network Vulnerability?

  • Software Update: The users who are using Wi-Fi connection should immediately update the software of their connected devices.
  • Using Wi-Fi Security Tool: You can use a Wi-Fi security tool for network vulnerability scanning or network vulnerability assessment. The tool can detect vulnerability and can take cybersecurity protection measures.
  • Changing Router’s Password Will Not Help: If you are thinking that changing the Wi-Fi password can safeguard against this vulnerability, then you are wrong. The basic purpose of the password is to protect the Wi-Fi router. But, this new vulnerability does not affect the router. Even if your router is password-protected, it still has the capability to put your data at risk because it directly impacts the user’s Wi-Fi enabled devices and the Wi-Fi network itself, and not the router.
  • Security Patch Update: If you are using an android device, then it will be wise to visit the website of the manufacturer and check for any security patches to tackle the said vulnerability.
  • Using Secured VPN: It is not necessary that all the device manufacturers have discovered a security patch for this problem. In such a case, how will you deal with the situation? One of the best options you have is to use a reputable VPN on all your Wi-Fi enabled devices. The purpose behind using a secured Virtual Private Network (VPN) is that it helps in web traffic encryption resulting in the safe transmission of data without worrying about data interception by any adversary.
  • Visiting Secured Websites: Another way of protection against this vulnerability is by using HTTPS-enabled websites only. It provides an additional layer of protection in the form of SSL encryption via the website that you visit.

5G technology has been introduced, which takes the Wi-Fi network to the next level. It is a good thing for the future, but with this new KRACKs vulnerability, the users need to be extra careful while using Wi-Fi, and this is the reason why we have come up with this post on WPA2 Wi-FI network vulnerability.
