If router security is not activated or if the owner deactivates it for convenience, it creates a free hotspot. Wireless security buying a new router with WPA2 capability.
This is especially true if the laptop is also hooked to a wired network. It is not necessary for the attacker to be in the area of the network using this exploit.
Most wireless systems allow some kind Wireless security MAC filtering to allow only authorized computers with specific MAC IDs to gain access and utilize the network. The DoS attack in itself does little to expose organizational data to a malicious attacker, since the interruption of the network prevents the flow of data and actually indirectly protects data by preventing it from being transmitted.
In an organizational environment, where most wireless devices Wireless security "on the air" throughout the active working shift, MAC filtering provides only a false sense of security since it prevents only "casual" or unintended connections to the organizational infrastructure and does nothing to prevent a directed attack.
If an employee trusted entity brings in a wireless router and plugs it into an unsecured switchport, the entire network can be exposed to anyone within range of the signals. There does not exist a full scope model of such threat. However, there are effective countermeasures like disabling open switchports during switch configuration and VLAN configuration to limit network access that are available to protect both the network and the information it contains, but such countermeasures must be applied uniformly to all network devices.

Once this is done, the hacker connects to a real access point through another wireless card offering a steady flow of traffic through the transparent hacking computer to the real network. A direct bridge, which requires the user actually configure a bridge between the two connections and is thus unlikely to be initiated unless explicitly desired, and an indirect bridge which is the shared resources on the user computer.
However, each new mode of operation will create new options of threatening. The idea behind this type of attack may not be to break into a VPN or other security measures.
