Your wireless network isn’t as safe as you thought it was.
Security researcher Mathy Vanhoef has discovered a serious flaw, that he’s calling KRACK, in the WPA2 protocol that secures almost every modern Wi-Fi network. The vulnerability could allow hackers to inject malware into websites, or spy on people by reading information that was until now assumed to be encrypted.
Android, Apple, and Windows software are all said to be affected by KRACK attacks on some level.
The Wi-Fi alliance, which certifies Wi-Fi devices, says that “there is no evidence that the vulnerability has been exploited maliciously.” It also adds that the issue “can be resolved through straightforward software updates.” Now, we just need to wait for those software updates to arrive.
