I am pretty sure that the only reason bitthief even exists is to show the weakness in the Bittorrent protocol. I think we all should be greatefull and anyone who makes a true client, manages a tracker, or works on the protocol should look at bitthief and find a way to fix all the explites they use as well and some of the privacy flaws, I honestly don’t want everyone else who downloaded hacking manuals to know my IP address, even though I have a dynamic address and know how to instantly change it

First of all, bitthief is wrong. But I think it should be not difficult to a small group of leechers to change the code of their clients to leech faster without upload, as BitThief shows (and happened before with leech eMule clients). What’s the point in banning named clients if everyone could change a Vuze client to steal bandwith? The change should be at protocol level (IMHO).

I guess there is no honor among thieves after all. It’s funny to hear pirates complain about what they are guilty of. The very same justifications for doing what they do can also be used by BitThief users too. Don’t be a hypocrite, keep on stealing what you can and be happy. I know it hurts to be cheated, but how do you think the media industry feels? Most pirates need to climb down from their high horse and accept the reality of this and deal with it, just like the media industries do. Evolve or die, remember? Thank BitThief for forcing BitTorrents to evolve. We want anonymous, fair, and secure BitTorrents for ALL.

So, BitThief is made by peeps in Zurich.. Hmmm. Ya know, that’s where Rapidshare has all it’s servers too. Hmmm.. Conspiracy?

I have to use this sort of upload blocking. I have already been contacted by my ISP about seeding torrents. Their policy is that the next time a torrent goes out from my comp my service gets shut off. It sux here in the US because of this crap. Damn Comcast.

[...] The Java based BitTorrent client continuously sends user data to their server. Currently it collects the torrent hash, total size of the download, the current version of the client, total number of pieces available, and the size of these pieces. Since the data is posted on their server, it is possible to link all this info to the users’ IP-address. [...]

Seems to me we’re all missing the point and we’ve not really understood the rationale behind BithThief’s creation in the first place. I’ll admit as first I was one of those. I actually thought this was tied up to the RIAA/MPAA at one point
The BitThief creators, I believe, are actually trying their damndest (WITHOUT being nefarious) to point out an inherent weakness/set of weaknesses in the underlying protocol.
They’re arguing that the underlying protocol needs to be modified so that what BitThief in particular does is NEVER allowed to happen.
Believe me I think these guys are definetly Pro-BT and they’re using science to promote it. They’re on OUR SIDE guys.

Good post by anonymous.
I wonder why it is that bittyrant is getting most of the bad rap ?
bitthief is a leeching cheat that exploits and ignores the protocol to the max .
They even write in their paper that this clients concept could be used by
anti-p2p groups to destroy swarms . I think it’s good that they publish it, that allows
the right people to do something about it ..

[...] Se o BitTyrant Ã© pelo menos “anti-social”, o BitThief faz troÃ§a das regras e convenÃ§Ãµes do protocolo BitTorrent, bem como das de todas as redes P2P, constituindo a arma ideal para todos os “abusadores” (leechers) que apenas querem receber sem darem nada em troca e contribuirem para o aumento dos recursos de todos. Desenvolvido pelo LaboratÃ³rio de Redes e Engenharia de Computadores de um Instituto TecnolÃ³gico de Zurique, o programa permite efectuar downloads de torrents sem fazer qualquer upload atravÃ©s do recurso a uma sÃ©rie de alteraÃ§Ãµes que, segundo o TorrentFreak, faz com que se apresente constantemente Ã rede “como um novo par recÃ©m-chegado sem nada para dar”. Tal como o BitTyrant, o BitThief tambÃ©m se baseia no Azureus, sendo por isso escrito em Java (apenas disponÃvel para Windows e Linux). [...]

It’s academic research, so it should be public so everyone can profit from it. And by “profit”, I don’t mean that you should use it to download stuff, I mean that it should be used to harden the bittorrent protocol and servers.

Sooner or later someone would have written such a client. The BitThief people made it public and “blam!” the torrentfreaks are thinking about ways to prevent such clients from flooding the network. Like “blah” said, full disclosure.

Prevent repeated "new" connections from same IP — Fri, 05 Jan 2007 22:41:13 +0000

Wouldn’t it be possible to greatly slow BitThief by designing clients / trackers to refuse to allow the same IP address to repeatedly re-announce itself as a “new client” within a time interval (eg 60 minutes)? Therefore a BitThief client downloads a packet, disconnects, attempts to re-connect as a “new client” and is denied connection. Maybe set this to allow one or two re-connections to allow for someone who accidentally canceled their download and is attempting to re-start, or whose ISP hiccupped.
That means that the BitThief client would only be able to download one packet per hour from each seed/peer, and if the IP address of BitThief clients detected in this manner was noted by the tracker, they could be banned for say 12 hours (remember many home users are on DHCP, so their IP address changes sometimes, a permanent ban is not good).

Just a starting point for discussion.

I don’t see why they wouldn’t make it public just because they’re academics. Someone could easily develop their own client based on their research.
Which would you rather be able to claim when it matters: a) we did some research on selfishness in the bittorrent protocol or b) we did some research on the bittorrent protocol, including the development of a client which quickly gained some popularity amongst a subset of bittorrent users, was reported in xxxx places included articles in xxxx and xxxx, the effects of which was a discussion of the robustness of the bittorrent protocol and the development of method to prevent selfish users. or something that could possibly go along those lines.
full disclosure and all.
