One of those is the power-save message, that signals the access point that the given client is going into a low power state. At least that’s the idea, but this attack finds a couple techniques to bypass that protection.Ī bit more background, there are a couple ways that packets can be delayed at the sender side. The WPA encryption schemes introduced pairwise encryption, ensuring that not even other authenticated users can sniff each others’ traffic. We’re first going to talk about the WiFi vulnerability, also known as Framing Frames (pdf). There’s a naming overload here, as two bits of security news this week are using the “MacStealer” moniker.
