Security researcher Brian Krebs has uncovered the involvement of credit bureau Experian in an ID theft operation, according to ZDNet. Experian became involved through their March 2012 acquisition of Court Ventures.

Through research, Krebs demonstrated that Court Ventures had sold data to Superget.info, a “fraudster-friendly” site that marketed the ability to look up personally-identifiable information on millions of Americans. Krebs cites an interview with Marc Martin, the CEO of another information services company which had a relationship with Court Ventures; Martin says a U.S. Secret Service investigation of Experian related to ID theft and data sold to Superget.info.

Individuals at Superget.info were based in Vietnam, and they have a history of involvement in ID theft, the article says.
