Little is known about how U.S. 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.

The Tor Project, is a nonprofit that relies in part on donations. The project “currently doesn’t have funding for improving the security of hidden services,” wrote Andrew Lewman, the project’s executive director, in a blog post on Sunday. ( https://blog.torproject.org/blog/thoughts-and-concerns-about-operation-onymous )

It is possible that a remote-code execution vulnerability has been found in Tor’s software, or that the individual sites had flaws such as SQL injection vulnerabilities. But Lewman wrote The Tor Project had little information on the methods used by law enforcement in the latest action.

“Tor is most interested in understanding how these services were located and if this indicates a security weakness in Tor hidden services that could be exploited by criminals or secret police repressing dissents,” he wrote.

Can anybody help Andrew Lewman understand what happened ?

    Yeah, I used to do some development related to Freenet, but that was a long time ago. I haven't really used it since the 0.5/0.7 split, so at this point most of my knowledge about it is largely theoretical, and based on running the network on old hardware on a 6megabit connection -- so hopefully it's a bit better now ;)

    However, at the time that I used it, there were already a few attempts to have set up something like Craigslist. The biggest problem was payment though -- this was years before Bitcoin. There was a lot of talk about how to design a crypto-currency and how that would enable Freenet marketplaces, but obviously none really took off without that.

    With Bitcoin now...you could make it work, but it would probably be pretty slow to make and confirm transactions. You can't really have anything that's interactive, but payments don't necessarily need to be. Seller posts what they've got and what the price is, buyer messages them and provides bitcoin data, seller ships the goods. With the price fluctuations on Bitcoin it'd probably be marked up even more than Silk Road already is though, since your payment could be in transit for as long as several hours.

    Other than the time delay, that sounds better than what people have been doing on Tor in quite a few ways. The less interactivity, at least when it comes to the web, generally means the smaller the attack surface. Scripting in general is best left for the clear net. I'd be curious if Bitcoin would work with Freenet, or if it'd need its own cryptocoin like I2P does, due to network design, as that would definitely pose an issue with getting the ball rolling (if you think Bitcoin is unstable with a small userbase, just think about how fun doing business with Anoncoin must be...).
