The AP has a profile of Anna Chapman, one of the people accused of serving as Russian spies in the United States. I'm not sure if she's guilty or not, but she bears a striking resemblance to the Black Widow. The Boston Globe has a profile here of other suspects. The common thread seems to be these folks tried really hard to network, whether that was online or in person. Chapman and Tracey Lee Ann Foley, one of the Cambridge-area suspects, both worked in real estate.
