MediaDefender’s Decoy Effectiveness on BitTorrent Sites

MediaDefender’s email and anti piracy tool leaks gave the world an unique insight into the workings and the effectiveness of their BitTorrent decoy operations. So how effective were they? And which sites were best protected against these fake torrents? Let’s find out.

MediaDefender's Decoy Effectiveness on BitTorrent SitesMediaDefender determines the effectiveness of their spoofs and decoys by analyzing the top search results for the file in question, mostly movies and music albums. If 2 out of 10 top search results are fake files spread by them, their effectiveness is 20% on that particular BitTorrent site. Their goals is of course to get as many fake files in there, hoping people will end up downloading useless data.

There is a lot of variance in the reported effectiveness between BitTorrent sites and the different decoy projects. We scanned through most of the reports and it seems that The Pirate Bay and Mininova were best protected against fake files whereas MediaDefender was more effective on sites like BiteNova and TorrentPortal.

Niek from Mininova, the toughest site to get onto according to MediaDefender, wrote a blog post in response to the leaked MediaDefender emails. He sums up some of the quotes that show how well protected Mininova is. Niek adds, “We can only be grateful for the many nice words from our friends at MediaDefender. All thanks go to our great moderating team, who did (and do) great work.”

The Pirate Bay always has been one of MediaDefender’s main targets because this site is often mentioned in the press. Unfortunately for MediaDefender The Pirate Bay is also one of the sites that is well protected against fake files.

In July, Brokep from The Pirate Bay already told us that they were doing all they can to block Media Defender from accessing their trackers. “We block them and some other torrent sites do as well.” he said.

This apparently annoyed MediaDefender, as we can see from one of their emails regarding the effectiveness of their decoys for Micheal Moore’s Sicko: “we still have no presence on Pirate bay which is a site they [Weinstein?] are likely watching as it was mentioned in the AdAge article they referenced.”

Here is an example of an effectiveness report for “Fantastic 4: Rise of the Silver Surfer” based on the top search results. Note that an effectiveness of 100% means that all the torrents that showed up in the search results (top 6/10/15) were fake.

BiteNova: 100%
Bittorrent.am 27%
Btjunkie 20%
Btmon 15%
BushTorrent 100%
ExtraTorrent 47%
Fenopy 100%
FlixFlux 23%
FullDLS 32%
IsoHunt 100%
Meganova 100%
Mininova 0%
Monova 35%
MyBittorrent 91%
NewTorrents 0%
Novatina 98%
PirateBay 0%

TorrentSpy 4%
TorrentValley 77%
TorrentView 27%
Torrentz 22%
Underground 0%
WorldNova 97%

    NOOOO!!! I love Isohunt.com because of all the multiple trackers it lists and gathers, but have never gotten a fake from any torrent site since the first time I downloaded a fake file from Torrentspy. But isohunt does have several fakes. Guess when you use a site that has a tendency for fakes you become a fake expert. lol Also Congratulations Newtorrent and ReleaseLog.

    i know which sites to bookmark and which ones to erase from my vocabulary.

    grats to everyone on the list with less than 5%. to all the others (above 5%), you suck a$$… get right or get left.

    September 23rd, 2007 | 07:55

    I agree demonoid as it is closed is one of the best sites when it comes to fakes…

  9. Hbkwarez
    September 23rd, 2007 | 08:21

    Is demonoid accessible to pubic at that ease as newtorrents!

    Personally after Private trackers when it comes to Public site torrents!


    i prefer newtorrents

    September 23rd, 2007 | 08:40

    yoh tbh i know when its a fake because i can check here and see if its been released or not
    the only real fakes they make are..

    axxo -great releaser but his name has been terrorised!!!

    NOTV -their torrents are being abused too most of their recent ones are being faked.

  11. LGx
    September 23rd, 2007 | 08:46

    Isohunt’s search engine is far the best. If you dl something, like Transformers, when it is now playing at he cinemas and the torrent says its a DVDrip, then its your fault to get a fake. Look after first what you want to dl.

    I’m surprised MediaDefenders-Defenders haven’t mentioned the torrent clients that have united with MPAA and other anti-privacy companies or maybe they have and I haven’t noticed. lol I was reading an article about Utorrent leaking information to anti-privacy companies.

  14. paul
    September 23rd, 2007 | 09:16

    yeah i belong to demonoid, sick of everyone stealing our torrents. every site. if you’re not a member you just look up our torrent on mininova or bitjunkie and there you go.

    i gotta say though, whenever i want summat i type the name and ‘rapidshare’ or ‘rs.com’ or ‘megaupload’ into google first, usuallyway better than a leeched to death torrent.

    i only got one fake movie in all my year of movie downloads, it was about 3 years ago it was a timer loop showing 5 4 3 2 1 and then started all again, from then on ive been more carefull and so far so good, going trough newtorrents and piratebay as my prefered public trackers

  20. September 23rd, 2007 | 10:37

    that’s simple, we manually update / check every single torrent on newtorrents, that’s something that almost none of the other websites do :) NTi forever!

  21. mondo74
    September 23rd, 2007 | 10:50

    new torrents and demonoid are the best two sites, i`ve never ended up with a fake from either of them
    keep up the good work NTi

    September 23rd, 2007 | 11:05

    So…these fake torrents stop illegal downloaders because after they’ve leeched the fake they’ll never download an illegal file in their life again?

    September 23rd, 2007 | 11:22

    pure and simple copy/paste from a torrenfreak article … (not the first one by any mean), looks to me like you can’t rephrase anything and simply decide to steal content from other blogs … way to go!

    isohunt is good cos it adds new trackers in the torrents

    never in my life have i seen so many fakes at piratebay as now…and no, not all gets deleted either.

  27. philips14c
    September 23rd, 2007 | 12:31

    BTJUNKIE has multiple tracker support (over 90 billions users)! AXXO’s movies has thousands and thousands of peers and they last longer than any others torrents! And he doesnt compress the movies with rar like other noobs! LOL!

  28. rubob
    September 23rd, 2007 | 12:33

    hahaha, youre the biggest noob..
    axxo rips arent good at all, only stereo sound.

  29. philips14c
    September 23rd, 2007 | 13:02

    They are good enough for a lot of people! Anyway i dont download 2 CD releases (5.1 sound) of every stupid movie (stereo is enough)! Only the very good ones deserve souround sound!

    September 23rd, 2007 | 13:35

    ya good work new torrents i find myself useing that site alot more lately since iv been coming here to rlslog, never had a problem with anything from there or demonoid, am supprised at mininovas 0% i always thought thats where the majority of fakes where, shows how much i know! i guess it safe to use after all

    @24 the article has a link to torrentfreak at the bottem along with credit to the fella that wrote it … new comers that might not know about torrent freak now do, and got the chance to read it so can only be a good thing posting it here too

  31. September 23rd, 2007 | 13:46

    rubob: have to agree with you, there are many fake and virus containing files at TPB

  32. Greg

    Surely this belongs on the site somewhere (unless I missed it):

    TPB files charges against media companies

    Thanks to the email-leakage from MediaDefender-Defenders we now have proof of the things we’ve been suspecting for a long time; the big record and movie labels are paying professional hackers, saboteurs and ddosers to destroy our trackers.

    While browsing through the email we identified the companies that are also active in Sweden and we have tonight reported these incidents to the police. The charges are infrastructural sabotage, denial of service attacks, hacking and spamming, all of these on a commercial level.

    The companies that are being reported are the following:

    * Twentieth Century Fox, Sweden AB
    * Emi Music Sweden AB
    * Universal Music Group Sweden AB
    * Universal Pictures Nordic AB
    * Paramount Home Entertainment (Sweden) AB
    * Atari Nordic AB
    * Activision Nordic Filial Till Activision (Uk) Ltd
    * Ubisoft Sweden AB
    * Sony Bmg Music Entertainment (Sweden) AB
    * Sony Pictures Home Entertainment Nordic AB

    Stay tuned for updates.

    And for the record, there are certainly times when I have gotten axxo releases. I have a crappy tv at the moment, so stereo sound is all I have anyway (good eqiup got screwed up in move and haven’t replaced it yet). BUT I would like to comment that calling someone a ‘noob’ for using rars is ridiculous. Why? Because if you read up on Official Scene Release Standards, the rars are required. So that means you’re saying that every ‘higher up’ in The Scene is a noob… which is a gross misuse of the word ‘noob’ as many of them have been hard at work for years and years and have paved the road for, and are indirectly responsible for, pretty much everything you’ve ever downloaded.

    September 23rd, 2007 | 14:37

    Never really got a fake file, I wait until somebody else d/l’s
    stuff then read the comments, which are normally accurate.

    “BTJUNKIE has multiple tracker support (over 90 billions users)!” Posting 28
    You know that’s a lot of users. Earth has some 7 Billion humans so where is the rest coming from?
    Could you provide us a link where it is explained how that number is generated because 90 billions of users is bullocks in my eyes.
    Even if you are talking about hits then I have bloody hard time believing it.

    is it just me, or would anyone ever DL something from a site called “Bush Torrents”… that’s just steaming with anti-p2p sentiments. Anyhow… good work NTi. And keep up the good work.

    September 23rd, 2007 | 15:10

    @23: Which is why public torrents is a bad source for movies, apps and games. I don’t mean to flame, please delete my comment if you think this is the case. I simply think that if you can’t be 99% sure a release isn’t tampered with, it’s a bad source. This rules out public torrents and especially rapidshare links.

    However, if you are happy with public torrents, then just ignore my opinion. :)

    September 23rd, 2007 | 15:13

    Oops. I didn’t mean @23 in my comment above. I was refering to post 32. However not to martin directly but more as a general thing. (An edit function would be nice, but you can’t have everything ;) )

    private torrents? bullshit lol. as if they are better than public ones

    where do these private torrents get their source anyway.. from the “scene” or newgroups.. bunch of lamers.

    Which UNDERGROUND torrent site is the one mentioned in the report? What is its exact address?

  50. Thraprod
    September 23rd, 2007 | 20:22

    Demonoid has both a public and private tracker, actually. Some of their torrents anyone can get to, others require a login. I’m not positive how it is determined which are which though. I tend toward a few other private trackers myself. At least then there’s NO chance of fakes.

  51. Q
    September 23rd, 2007 | 20:58

    i think its http://www.underground.be
    but it just seams to search mininova and others

    September 23rd, 2007 | 22:21

    well I would say that newtorrents does has fake torrents the ones with the divo codec shit..

  53. B
    September 23rd, 2007 | 22:55

    @48 and @51
    It is determined by How old is a torrent

    The newer torrents are public
    after a week same torrent will be private and will require a ligin to access but if u have the torrent file u can still continue to download

    Rar allows for files to be planted in pieces all over the globe. Imagine a torrent gets uploaded to tpb. 15 different people have fifteen different pieces, making one copy. Now thats a nice way to seed. no one has all of the files, and it is nearly impossible to track the original source as it appeared at once in many pieces. Now imagine a 100 piece rar set with 100 accounts all over the globe…

    Let’s start some team seeding. Azureus supports this, I wonder what other client software does…
