The Tor Project wonders how the feds took down hidden websites

Little is known about how US and European law enforcement shut down more than 400 websites, including Silk Road 2.0, which used technology that hides their true IP addresses. The websites were set up using a special feature of the Tor network, which is designed to mask people’s Internet use using special software that routes encrypted browsing traffic through a network of worldwide servers.

Last week’s takedown of Silk Road 2.0 wasn’t the only law enforcement strike on “darknet” illicit websites being concealed by the Tor Project’s network of anonymizing routers. A total of 410 .onion pages on at least 27 different sites, some of which sell everything from drugs to murder-for-hire assassins, were shut down as part of Operation Onymous—a joint operation between16 member nations of Europol, the FBI, and US Immigration and Customs Enforcement. While 17 arrests were made, some operators of sites taken down by the worldwide sweep remain at large.
