The clever thing is that they took it over and for one month monitored it without the users knowing. Everyone on obfuscating their persona with Tor and bitcoins, still had to enter their postal addresses on the website, to receive the goodies. That database must be a wet dream for law enforcement.

If users were smart they would have PGP encrypted their address with the seller's public key.

From what I remember poking around at Hansa that's not true. Each vendor / user had a public key associated with their account. All text communication through the website was supposed to be with GPG encrypted text secured by private keys unavailable to website.

So law enforcement has lots of encrypted text along with some clear text from users not informed enough to follow any kind of opsec.

> Some 10,000 foreign addresses of Hansa Market buyers were passed on to Europol.

That's really bad, because not all countries are Holland, which is famous for its 'relaxed' attitude towards drugs in general, so some users might have their lives turned around by this - followed, arrested, jailed, extorted, etc.

I like how they try and color the site by associating it with sites that sell weapons and child porn. > It is Hansa Market, currently the most popular dark market in the ‘anonymous’ part of the internet, the so-called darknet. > ... > The darknet markets enable large-scale trading in chiefly illegal goods, such as drugs, weapons, child pornography, and ransom software. ... No weapons or child pornography were sold on…

Seems fair to lump in with the rest since it was in fact an illegal market place.

>This was made possible by the arrest of the two administrators of Hansa Market in Germany, aged 30 and 31. Since their arrest, the two men, from Siegen, NorthRhine-Westphalia, have been kept in pre-trial detention, and are only allowed to have contact with their lawyers. So admins of the other markets: always have a dead-mans switch.

I'm curious how you would construct a switch that couldnt be bypassed by the police once they have full access to the servers.

A dead man's switch could wipe the server and all backups to erase evidence. The police in this case let the server run for months to catch other sellers. A well hidden software trigger would have been hard for the police to notice without a thorough inspection of all the source code.

Dream Market is still up since Nov 2013. (1 year older than even AlphaBay) Perhaps they're the ones that are actually based in Russia ;P

You seriously have to be a moron to host your DNM in Canada or NL though, NL LE especially has many years of experience and millions worth of equipment for these investigations. Pick a place where they're less likely to have advanced DMA equipment handy! Even better though, is to choose a place where the FBI won't be able to fly a team with advanced DMA equipment.

In fact, I wouldn't be too shocked if the rather sophisticated wiretap gear the Dutch police have at AMS-IX was capable of identifying hidden sites with timing attacks.

Supposedly this was posted on Hansa forums by the staff in the middle of the takedown http://i.imgur.com/yowD1Vr.png

Earlier quoted context omitted.

Alert users that the market is compromised. An example, an admin could have a personal password that is used to update a secure hash of "last known time the market was not compromised". The users can use the public key to verify the markers. Every day or two, the admin updates that marker using the private key (password). A few days after they're arrested, they won't have updated it, the users will know something is…

This is an over engineered solution, and I never understood the value of these warrant canaries etc. In the right set of circumstances you would be compelled to hand over any keys (with their passphrase) in an investigation like this, and failure to do so would result in harsher penalties. People are the weak link here.

This is fanciful. It assumes both extreme competence and legal powers to compel just about anything, neither of which generally exist.

You can often be forced to unlock encrypted data as part of evidence gathering, but there's no legal power to make you conduct arbitrary processes which only exist in your head.

Because obviously it's impossible to express that one party might have viewed an outcome as favorable without agreeing with that view. /s

Services like these give Tor and related projects a bad name. Taking down illegal market places is part of the police's job and this is definitely a success story. The article is lacking in details a bit, but it seems they've taken it down using regular old police work as they mention an "undercover operation". This proves once more that the weakening of security for everybody is not needed to catch criminals.

> Services like these give Tor and related projects a bad name In more ways than one. What if this had been a tor website that was sharing documents proving government or police corruption? And yet somehow, the police did manage to shut it down. It goes to show that the tech needed for fully anonymous websites may not be good enough yet. Any sufficiently anonymous website that could be used for good reasons can also…

>It goes to show that the tech needed for fully anonymous websites may not be good enough yet.

The tech will never be good enough. Even if we had magic unexploitable webapps hosted in the platonic realm of pure forms whose privacy is protected by magic cryptography, darknet markets would still get busted. Darknet markets require support staff, managers and engineers to run the site. The humans who run such sites will always be exploitable.
