An anonymous reader writes: A Microsoft network engineer is facing federal charges in Florida for allegedly helping launder money obtained from victims of the Reventon ransomware. Florida investigators say that between October 2012 and March 2013, Uadiale worked with a UK citizen going online by the moniker K!NG. The latter would distribute and infect victims with the Reveton ransomware, while Uadiale would collect payments and send the money to K!NG, in the UK. Investigators tracked down Uadiale because this happened before Bitcoin became popular with ransomware authors and they used the now-defunct Liberty Reserve digital currency to move funds. Authorities from 18 countries seized and shut down Liberty Reserve servers in May 2013.
