Topic: The TRUTH about Darkcoin: ZERO Anonymity, EASY DOS attacks, & Amateur code base! - page 2. (Read 9018 times)

Cool, hiring someone to do criminal activities for your benefit - check with your momma first if she thinks it's a good idea.

If its true do it and I'll pay you. I hold a certain interest in dark coin competition. Also it would be better for everyone involved if this monster was killed before it becomes any bigger and hurts even more people. But lets just say ill believe its THIS easy when i see it myself.

Darkcoin is prone to several cost-less DOS attacks that can destroy the whole network.

I normally stay well clear of these debates, for obvious reasons, but I do get frustrated when I see well-articulated responses from people who are clearly intelligent advocating this obviously broken architecture, mostly through much hand-waving and placating each other.

Masternodes have to be available and connected to in real time in order to be used. Mixing is based entirely on their availability. Thus, in order to control a substantial number of masternodes one merely has to own a handful, and make the rest of the masternode network unreachable.

For even a script-kiddie-level attacker these techniques and funds are easily found.

Need to render 1100 masternodes unreachable? No problem - SNMP amplification attacks will let you use a handful of boxes to amplify the bandwidth under your control. When a datacenter sees a clear flood of traffic for a particular IP address at the datacenter their response is always automatic and the same - their upstream data provider blackholes that IP address at the upstream bordergate. This means that you can use SNMP or DNS amplification attacks to render a dedicated machine (never mind a VPS) inoperable and unreachable to the outside world.

The most critical take away for you today is that this problem is unsolvable at the userland level. In other words, no matter how much dev worship there is there isn't a magical line of code that can be written that can prevent amplification attacks from devices and servers that are unrelated to and unconnected to the Darkcoin network. It is something that cannot be controlled or influenced.

The solution would literally be for Darkcoin to scrap masternodes and go back to the proverbial drawing board to find an architecture that uses passive blockchain mixing or similar, but I suspect it is too late and there are too many stubborn heads for that.
