We offer the unsealed FBI complaints which led to the recent bust of two Kazakstan "hackers" accused of extortion for breaking into Bloomberg's computer system and asking for $200,000 to tell how it was done: http://cryptome.org/bloomberg-bust.htm The complaints describe how the defendants were traced through Hotmail addresses, a sting was arranged, and Bloomberg helped make the bust by setting up an offshore bank account to lure the hackers to London. One coconspirator remains a fugitive -- the lady who made a cellphone call to verify the money was in the bank. The US Attorney and FBI praise the business/law cooperation in battling computer crime and boast of how computer crime has led to improved global law enforcement.
