Lell’s post on the topic suggests Belkin’s Surf N150 Model F7D1301v1, N900 Model F9K1104v1 and N450 Model F9K1105V2 are all susceptible to the attack.Mac WiFi Problems are one of the common issues for Mac users.

Lell’s revelation, which he says makes it possible to deduce passwords by drawing up a simple substitution table, means all an attacker needs to do to compromise a device is learn its MAC address and then spend a few minutes converting it into Hex. Some models even advertise the address on the case of the device! In either case, that’s problematic because it is possible to interrogate WiFi routers in order to learn their MAC address. Since the WAN MAC address is the WLAN MAC address + one or two (depending on the model), a wireless attacker can easily guess the wan mac address of the device and thus calculate the default WPA2 passphrase. Update The default WPA2-PSK passphrase used in some Belkin routers simply replaces a character of the device’s MAC address with another hecxadecimal character, according to security blogger Jakob Lell.Įach of the eight characters of the default passphrase are created by substituting a corresponding hex-digit of the WAN MAC address using a static substitution table.
