Wireless networks are capable of being affected by many attacks, along with an attack known as the wormhole attack. A wormhole attack is very difficult to prevent because of its effectiveness. In wireless network wormhole can cause a meaningful breakdown in communication. During a wormhole attack, an attacker receives packets at one point in the network, "Tunnels" them to another point in the network, and then replays them into the network from that point. It is also possible for the attacker to forward each bit over the wormhole directly, without waiting for an entire packet to be received before beginning to tunnel the bits of the packet, in order to minimize delay introduced by the wormhole.
