Wireless Internet Tips
While the number of publicly accessible wireless Internet locations or “hot spots” continues to increase, it is important for consumers of New York State to be aware of the dangers associated with surfing the world wide web in an unsecured environment.
While having access to the Internet in a coffee shop or park is extremely convenient, such use may put individuals' privacy at risk.

This rogue network is established in a location within close proximity to the preexisting, trusted network, and designed or named in a similar fashion in an attempt to deceive users. Such networks are often referred to as “Evil Twins.” Unfortunately, users will frequent locations offering free wireless access and may neglect to identify any inconsistencies between the two available networks. Information sent over these "Evil Twin" networks may be susceptible to theft, including but not limited to e-mail, banking information, passwords and so forth.
