FBI arrested Ross William Ulbricht, 29, alleged owner and mastermind of Silk Road. Site operated on the Tor anonymity network, which directs traffic through a volunteer network of more than 3,000 relays that make it extremely difficult to trace Internet activity. Site was also used in selling malware, exploit tools, stolen credit card numbers, fake driver’s licenses, passports and social security cards. Silk Road’s downfall appears to be linked to human error, according to a researcher at the International Computer Sciences Institute.”]
