NETMODE is a Ducky Script command which specifies which network mode to use in a given payload. These network modes determine how the Shark Jack will interface with the network. This command was added in Shark Jack firmware version 1.1.0 and is not available on Shark Jack 1.0.0 or 1.0.1.
In this mode, the Shark Jack will attempt to obtain an IP address from the target network via DHCP. This is the most common network mode.
In this mode, the Shark Jack will run a DHCP server and offer an IP address to the host computer on its network in the 172.16.24.0/24 range, similar to Arming mode. This network mode enables attacks against individual computers via Ethernet rather than the network as a whole.
In this mode, the Shark Jack will not offer or attempt to obtain an IP address from DHCP and may be used in conjunction with passive network sniffing programs when more stealth is desired.
