Are centralized networks doomed from the start ?

Recently I heard bad rumors around the DC network. Some malevolent person ( unknown ) has written several scripts for the most known DC hub software, that allow the hub owners to use their users in abusive forms of flooding, using the CTM feature of the protocol. These scripts have started to spread around and now “script kiddies” use it for flame wars and endless childish attacks.

Also, important sites that currently hold on the DC community like the major hublists OpenHublist or DCHublist and the ADC counterpart ADCHublist were attacked and were down for a long time. The major community for ADC , ADCPortal was also attacked ( ADCPortal also provide an alternative wiki to the one on the ADC Project ).

My first concern is that this problem can spread up to the centralized networks principle. In this case, the central node ( hub ) has the power to absolutely control the leaves that are connected, thus it can abusively send them in possible attacks at wish. This might be a serious problem for the centralized networks.

Secure policies have to be enabled in clients and hubs so that this kind of flaws do not affect the community. I don’t know yet if it’s possible in this current situation or the whole concept of centralization is flawed. I hope not, because the Direct Connect community has it’s advantages and there are a lot of people involved and which benefit from it every day.

My advice from the users: make sure you actually know what hubs you are using, and how your client can be abusively used for other purposes than the ones designed, and make sure you are using a proper firewall and perhaps package inspection to see if your computer is not part of a BotNet or similar flooding network.

And one last thing, Happy new year and all the best from the DC++ team.
