The Dutch authorities are really quick. I always wondered about Mixers, some survived for so long, some like Bestmixer just got caught so easily. $200 million is a lot of money,,, but I wonder also how did the authorities determine that was the amount of money laundered? Like if they find out other mixers, I thought it was mainly for privacy?
Well the obvious answer is that they are not anonymous,
. Maybe the authorities are really looking and casing everything before they seize Bestmixer, as for the implications? could lead to arrest. Remind me of this thread,
Breaking Mixing Services.
The most important conclusion of my work is, that even though a mixing service/a mixing algorithm might seem to be reliable at the moment, through a single leak/implementation fault, an attacker could be able to deanonymize any past transaction which has been processed by the mixing services. Even though the leak/implementation fault gets fixed by the service, every transaction which has been processed prior to the fix is irreversible vulnerable.
bitmixer.io & coinmixer.se are offline now, however its still possible to use the bugs I describe in my thesis to reverse nearly all transactions which have ever been processed by these services.
In my thesis, I attacked coinmixer.se (at the time of writing it was the biggest centralized mixing service), however - except chipmixer.com1 - every other centralized mixing service I checked could be broken in a similar fashion.
And two months after Felix release his thesis, one mxing services fall down.
