Breaking news in the tech world reports that all Wi-Fi networks around the world are prone to hacking because of weakness in the wireless security protocol. Belgian researchers discovered this vulnerability and published their findings to notify the world.
Their findings mean that the Internet traffic between your devices and Wi-Fi networks can be peeped on and used by hackers. Fortunately, you can do some things to protect you from the exploit above.
The Vulnerable Security Protocol
Wi-Fi connections have a security protocol called Wi-Fi Protected Access 2 (WPA2). Since it first came out in 2004, WPA2 seemed to be a strong security measure. Recent research findings indicate a weakness in the protocol, however, dubbed Key Reinstallation AttaCK (KRACK).
The KRACK Exploit
Your devices and Wi-Fi networks use a four-way handshake process to connect to each other. KRACK exploits that process by targeting your devices. A hacker can then access sensitive online information without the use of a password.
All devices and Wi-Fi networks that use WPA2 is prone to hackers. Current Windows and iOS devices, however, have less vulnerability because of the different way Microsoft and Apple use the WPA2 protocol. Sadly, Linux and Android devices lack that kind of security.
The Protection Measures You Can Take
To protect your devices and sensitive information then, you can continue using WPA2 since it remains to be the most secure security protocol. You can also update your devices with the latest operating system updates available. Manufacturers are already working on patches to fix the vulnerability.
The KRACK exploit has one caveat that can be good news: hackers need to be within the range of the Wi-Fi you are using to hack into your device. This means hackers can likely attack you on a public Wi-Fi than a home or office Wi-Fi.
Security expert Private Tunnel suggests that you can protect yourself, nonetheless, on a public Wi-Fi with the use of a VPN application that can encrypt your online traffic.
The KRACK exploit may be cause for concern, but with the measures above, you can keep yourself safe.
