Avast business product portfolio delivers VPNs, patch management, and security assessments to compromised Wi-Fi networks
Due to a new security vulnerability uncovered on Monday regarding WPA2 (Wi-Fi Protected Access II) protocol, it’s been a busy week for IT teams tasked with securing business networks—not to mention employee devices and machines.
WPA2, a security technology used on all certified Wi-Fi hardware and Wi-Fi networks, enables the strongest encryption option for wireless network traffic. An upgrade from WEP (Wired Equivalent Privacy), WPA2 protects and secures communications across routers, mobile devices, and internet of things (IoT) devices.
Through the new vulnerability, dubbed KRACK (Key Reinstallation Attack) and uncovered by security researcher Mathy Vanhoef, any device using WPA2 encryption could be a target for attackers looking to gain access to secure Wi-Fi networks, intercept and steal data transmitted across a Wi-Fi network, and potentially access computers and other devices on those networks.
According to Michal Salat, our Threat Intelligence Director, “The vulnerability puts any WPA2 protected network at risk, especially public networks such as those offered in hotels and restaurants. Android version 6.0 and higher and most Linux distributions are particularly easy targets as the bug in these implementations can force the client into resetting the encryption key to a predictable value of zeros, allowing complete takeover of communications.”
The range of modern Wi-Fi and the close proximity of some small business offices to other establishments leads to plenty of opportunity for someone to gain access to an SMB’s Wi-Fi traffic and subsequently compromise the SMB’s network.
According to Salat, “It’s important for users to be extra vigilant when logging into online services. To further mitigate the risk of disclosing wireless internet traffic to bad actors, other secure protocols like HTTPS should be used when browsing the web. Luckily, most websites provide HTTPS certificates. They can be identified by the green padlock in the browser’s address bar.”
