Residents of Nevada should think twice before they jump on an unsecured Wi-Fi network to do their online shopping.

That's because the Silver State ranks number one in the country with the most identity theft and fraud, according to a study by WalletHub.

The personal finance site analyzed identity theft and fraud complaints per capita, as well as reported losses due to this criminal activity and state legislation to protect consumers.

Based on that, WalletHub ranked all 50 states and the District of Columbia.
