Microsoft Beefs Up Wi-Fi Protection

Microsoft has begun pushing out its May 2019 Windows 10 update, which will flag Wi-Fi networks that are using the outdated and insecure Wired Equivalent Privacy WEP and Temporal Key Integrity Protocol TKIP authentication mechanisms. WEP was introduced in 1997 as part of the original 802.11 Wi-Fi...

The Future of Wi-Fi Security: Assessing Vulnerabilities in WPA3

By William Chalk A new study by researchers Matty Vanhoef and Eyal Ronen revealed five vulnerabilities – collectively named ‘Dragonblood’ – in the WPA3 Wi-Fi standard. Four of the five are considered a severe threat to online security. What does this teach us about trust in our networks? WPA3 Wi-...

FreeBSD : FreeBSD -- SAE confirm missing state validation (98b71436-656d-11e9-8e67-206a8a720317)

When hostapd is used to operate an access point with SAE Simultaneous Authentication of Equals; also known as WPA3-Personal, an invalid authentication sequence could result in the hostapd process terminating due to a NULL pointer dereference when processing SAE confirm message. This was caused by...
