What is KRACK?
KRACK stands for Key Reinstallation Attack and has become a serious problem in the tech world. The KRACK Attack takes advantage of a Wi-Fi network security flaw at homes and businesses. Essentially, the attacker reinstalls your network for their personal access, which remains unnoticed to the user. Doing this enables the attacker to decrypt personal information exchanged between the Wi-Fi access point and your device. To defend your information from this predatory programming, you should know what it does to your system.
Virtually any Wi-Fi network that relies on WPA or WPA2 encryption is vulnerable; this means practically every Wi-Fi system in the world is exposed. The attacker takes advantage of this weakness by setting up a Wi-Fi network with the same name (SSID) as an existing system that targets a specific user or groups of users. When they detect someone trying to connect to the original network, they send packages of data that force the device to switch to another channel and join the artificial system. Hackers change the encryption key and gain access to information that the user uploads or downloads, without them ever knowing. Conventional operating systems like iOS, Android, Windows, OSX and others are much more susceptible to this type of intrusion.
Don't Let Attackers Steal Your Privacy
Attacks like this are easily preventable by making sure your router is up-to-date. Router vulnerability has the tech world scrambling to eliminate this risk, and many companies have issued firmware updates allowing users to upgrade their networks as a form of prevention.
If your router's hardware company hasn't issued an update yet, other options are still available. These alternatives are especially useful for people who use public Wi-Fi as these services may not have upgraded their firmware recently.
Be sure to check for a green lock icon in front of a URL, to guarantee the website you are visiting is using an SSL Certificate, which prevents the KRACK vulnerability on that specific site. Also, use a Virtual Private Network (VPN), which adds an additional layer of encryption when you are on Wi-Fi. These networks allow you to establish a VPN on your device on any Wi-Fi connections you make.
Don't let a fake network fool you into giving up your credentials and confidential information. Updating your router, surfing secure sites, and finding the best VPN for you are steps you can take to prevent a KRACK attack from wreaking havoc on your data.
