Head’s up, Washington, D.C. — according to a list compiled by online security provider Norton and research firm Sperling’s BestPlaces, the U.S. capital has the highest number of cybercrime risk factors in the nation. Seattle, San Francisco, Atlanta and Boston round-out the top-five riskiest places.

The evaluation took a close look at data from a total of 50 U.S. cities, examining factors such as the number of computers and mobile devices in a city, unsecured Wi-Fi hot spots and social networking use, in determining the rankings.

While cities with the greatest risk factors don’t generally mean they have highest infection rates, reflection that many consumers have taken steps to keep their online information safe.

“In our examination of the riskiest online cities, we’ve considered a number of factors that can potentially affect online safety,” said Bert Sperling, founder of Sperling’s BestPlaces and lead researcher for the analysis, in a statement. “By looking at data from consumer lifestyle habits as well as cybercrime data provided by Symantec, maker of Norton products, we’re able to provide a holistic view of the various factors that put a person at potential risk.”

The research found that Washington D.C. had placed high in almost all of the factors measuring potential risk, including the second-highest usage of smartphones. The city also placed high in other criteria, including attempted malware infections and Web attacks.

Seattle, which topped list of riskiest cities in 2010, was also at the top in many of the risk categories, including email use and social networking.
