Grad Student Project Uses Wikis To Stash Data, Miffs Admins
Anonymous writes "Two graduate students at the Ivy League's Brown University built a P2P system to use abandoned wiki sites to store data. The students were stealing bandwidth from open MediaWiki sites to send data between users as an alternative to BitTorrent. There was immediate backlash as site operators quickly complained to the University. The project appears to be shutdown, but many of the pages still remain on the web. The project homepage was also taken down and the students posted an apology this afternoon." The same submitter links to two different forum discussions on the project.
Google Cache still has the old data.

Graffiti Networks
A Subversive, Internet-Scale Peer-to-Peer File Sharing Model
Abstract:
The proliferation of peer-to-peer (P2P) file sharing protocols is due to their efficient and scalable methods for data dissemination to numerous users. But many of these networks have no provisions to provide users with long term access to filesafter the initial interest has diminished, nor are they able to protect users from malicious clients that wish to implicate them in incriminating activities. We present a new file sharing paradigm that harnesses the potentially unlimited storageof the Internet as a third-party intermediary for peers to indirectly transfer data with each other. We base our decentralized architecture on the premise that users trust file sharing coordinators, but do not trust any other user. Our key contributions in this paper include an overview of the design for a P2P system that implements our new model and a discussion ofthe challenges that such a system will likely encounter.

The fact that some "admin" abandoned a site, with open privileges to post on it, does not constitute theft. I manage servers and write code for a living, and while I'd put a stop to such practices on any site I managed, the use of the term "theft" is laughable.
This is very much reminiscent of Microsoft crying to the media that all their security problems were due to evil hackers, and not their abject failure to follow long-accepted industry practices for code reviews and architecture. My response: cry me a river, and congrats to the grad students for their innovative work in the field of distributed communications.

...I want to hear more about these MILF admins.
It's just stupid. "Hey, we noticed that three quarters of that privately owned parking garage over there isn't being used at any given time. Why don't we open up a car salvage business and store all the derelict junkers that we're parting out in their unused parking spaces?"
These are graduate students?!?
Apparently they don't know about SlashdotFS. This system uses an english hidden markov model sentence constructor to generate plausible comment text and save it as reply's on slashdot. The path through the markov model is variable having multiple word choices at each node so it can encode arbitrary data and can be decoded by replaying the message through the same network model.
It was just a toy till 2003 when a pair of graduate students realized the information density could be dramatically enhanced by introducing spelling, gramatical errors, typo's and l337-speak into the model.
Comments encoding these are usually late posts in the discussion threat and frequently replied to by grammar nazi's.
It's now one of the major Warez dumping sites since it is particularly useful for immutable data of low value.
Some drink at the fountain of knowledge. Others just gargle.
You're abusing TOR network, it was NOT meant to be used for high-bandwidth applications.
Please, stop doing it. Exit nodes do not have unlimited bandwidth.
Except being "unethical" doesn't get you put in jail. Only being "illegal."
I found their garbage on my site yesterday. It's not a high-volume site, but it sure as hell isn't abandoned. And after all this apologizing, one of the students still has the complete list of wikis they used available on his student page. This was a serious case of lack of oversight and/or bad judgment.
Poor means hoping the toothache goes away.
This could be demonstrated just as well on sites that they own / control. For instance, with a single domain name, 100 pastebin clones, 100 wikis could be set up and configured differently (i.e. subdomains).
Some of them could have active SPAM policing, captchas, etc .. others could behave as though they had a lazy / dead admin. Others could just mysteriously vanish (i.e. domain expired, no longer hosted, etc).
The results are the same, either way. I wonder why they bothered going for external sites to begin with? All they needed was a cheap p4 and some scripts to automate mediawiki installs.
Why didn't they just stay in the sandbox?

He experimented further. In one class he had everyone write all hour about the back of his thumb. Everyone gave him funny looks at the beginning of the hour, but everyone did it, and there wasn't a single complaint about "nothing to say."
In another class he changed the subject from the thumb to a coin, and got a full hour's writing from every student. In other classes it was the same. Some asked, "Do you have to write about both sides?" Once they got into the idea of seeing directly for themselves they also saw there was no limit to the amount they could say. It was a confidence-building assignment too, because what they wrote, even though seemingly trivial, was nevertheless their own thing, not a mimicking of someone else's. Classes where he used that coin exercise were always less balky and more interested.
As a result of his experiments he concluded that imitation was a real evil that had to be broken before real rhetoric teaching could begin. This imitation seemed to be an external compulsion. Little children didn't have it. It seemed to come later on, possibly as a result of school itself.
That sounded right, and the more he thought about it the more right it sounded. Schools teach you to imitate. If you don't imitate what the teacher wants you get a bad grade. Here, in college, it was more sophisticated, of course; you were supposed to imitate the teacher in such a way as to convince the teacher you were not imitating, but taking the essence of the instruction and going ahead with it on your own. That got you A's. Originality on the other hand could get you anything...from A to F. The whole grading system cautioned against it.
He discussed this with a professor of psychology who lived next door to him, an extremely imaginative teacher, who said, "Right. Eliminate the whole degree-and-grading system and then you'll get real education."

You couldn't be more wrong. When it comes to proof-of-concept research that illustrates a vulnerability, "If I didn't do it, somebody else would" is one of the noblest defenses known to man.
