Spyware Analysis of P2P Software 200

rhizome writes "Benjamin Edelman, a PhD candidate in Economics and a Law student at Harvard, has analyzed the hidden (or not) additions to a user's machine when they install some of the major Windows P2P clients. He analyzes the length and readabilty of their licenses, what is revealed or hidden in the software's installer and includes screenshots for illustration. Clear, concise and eye-opening."

    When someone who's both a lawyer and an economist says a license is difficult to interpret, I tend to believe them. Even his assertion that these licenses are obfuscated is, itself, obfuscated.

      He says at the bottom that much of the research was paid for by LimeWire. I was wondering throughout the article why he was givng LimeWire such a clean bill of health, when my experience has not been so good.

      The disclosure does say something for his integrity, but I fear his appraisal may be somewhat biased (intentional or not) in favor of LimeWire.

        I have to say that I think there should be an Open Source set up for independent reviews of things. Sort of like Consumer Reports (versus Consumer Review which was started by the major corporations to try to thwart Consumer Reports' highly accurate ratings). If done correctly, and an unbiased basis can be maintained, it might take off just like many of the software projects have done. Further, it could be used to show the actual state of where Open Source products are versus Closed Source products. In fact, Consumer Reports would be the place to do this since they are fairly independent and back up all of their statements with lots of test data.

        So if anyone from any of the major OSS companies is listening - you might want to help fund the testing of the various OSs via Consumer Reports as well as some of the Open Source Software (OSS) itself versus the Closed Source Software (CSS) versions. Like Open Office versus MS-Office and the like.

        Just a thought.

          I have a lot of respect for Consumer Reports. We used to have a subscription to it when I was growing up, and I always found it objective, scientific, and informative.

          Where CR doesn't distinguish itself is in technical evaluations, software in particular. I could wish for more rigor when it takes on projects like these.

          Historically, the rolloff makes a fair amount of sense, as CR writes for a general rather than technical audience. And, as I often argue, you can't understand computing infrastructure as if it were a kind of appliance. Appliances are finite. Infrastructure exists for its potential.

          But as our daily lives become increasingly involved with technology, I often wish that CR could use its leadership and methodology to inform the technology marketplace as well.

        I too remember helping Windows victims recover from being assaulted by LimeWire in the past. But they have seen the light and repented of their wickedness, including no spy/adware with more recent versions; and the software itself is Free Software, available under the GNU GPLv2. They even have a CVS repository. With those conditions, spyware would be a bit hard to get away with.

    It would be interesting to compare against the popular Open Soure ports to see if they're any less invasive by nature.

    What about Shareaza?
    • Well, I don't know if Shareaza is invasive (although I don't think so), but I do know that when I used it for a while a few months ago, it absolutely killed network performance for all other apps while it was running. I eventually uninstalled it for that very reason. I don't suppose it's anything sinister; most likely it's just a complete hog.
      • Shareaza isn't invasive: I used it for months with no ill-effects. It didn't kill my network, just slowed it down quite a lot, so it is not likely to be something sinister; if anything, it is a general problem, as Gtk-Gnutella on Linux causes connection timeout errors for me on any other apps while it's running.

      It's impossible by definition. If it is an open source share app with spyware it will last like fifteen seconds before someone else gets sick of that and releases it without spyware. :nod:

      LimeWire is open source and is safe. I did a quick check [gondwanaland.com] of several other open source P2P apps (BitTorrent, eMule, Phex, and Shareaza). None are bundled with malware and if they have a license agreement it is only the GPL. All of the proprietary apps checked are unsafe, and it is well known that others not checked (e.g., Grokster) are also not safe.
    • iMesh and Kazaa use the FastTrack network, a propietary technology developed by a Swedish company. They need to pay this company licensing fees to use the network, which is probably why no exact open-source, adware-free equivalents exist... unless you count the hacked "light" versions of these two that have the adware removed but can still access FastTrack.

    • LimeWire is open source, the pre-compiled binaries have banner ads, as noted in the article.

      But usually, open source P2P clients have typically been fairly free of spyware. However, there have been a lot of cases where some people have taken the binaries, added spyware, then made it available for download. (At least Azureus got hit by that.) Nothing to do with coders, there are just people who want mess up the distribution somehow...

    The relevant parts, for people who can't or don't want to RTFA:

    My testing uncovered no bundled software installed without at least some disclosure apparent in a careful and complete reading of all applicable installation license agreements. However, it is possible that programs were installed that I failed to detect, especially if bundled program installations were set to be delayed after installation of the requested P2P software.

    Although each P2P installer included at least a vague reference to each program to be installed, certain P2P programs' installation procedures nonetheless present cause for concern. For one, substantive disclosures are generally detailed only in license agreements presented in scroll boxes -- often squeezing thousands of words of text into small windows requiring dozens of page-downs to view in full.

    I'm not so worried about spyware. At least not the commercial type, since you can figure out their motivations. Actually, I think the best response there is not spyware blockers, but a commercial response. There should be an anti-spyware organization that gives negative publicity to the companies that benefit in any way from spyware, and positive publicity to their competitors. If they're doing it for money, then you hit them in the wallet and they'll wake up.

    However, the think that really worries me is the intersection between P2P and black-hat-hacking skills. That's too much power in one place, and we already know that power corrupts. (The only redeeming point is that sometimes the corruption is pretty funny, like the Gannon/Guckert case.)

      Robogun,

      Preparing these detailed analyses is surprisingly time-consuming -- lots of license text to read, lots of screenshots to make, lots of measurements and other tests (registry, filesystem, etc.). So at least for this initial run, I had to limit myself to a manageable number of P2P programs. In general I tried to focus on the programs believed to have largest market share -- the programs that would infect the most PCs with unwanted software if such programs in fact contain unwanted software.

      WinMX would be a good candidate for inclusion in a follow-up piece. And there are plenty more too.

      Or perhaps someone else will be so kind as to take over where I've left off!

        You'll see that my site contains (what I claim to be) screenshots of the LimeWire install. I also have registry and filesystem change-logs, which I can post if needed (i.e. if they're actually helpful or of interest, which seems a bit unlikely).

        Can you say more about the LimeWire installation you tested? Where did you get the installer program? Was this current testing? Are you sure you have the current installer?

        I don't mean to suggest that current behavior excuses past bad decisions -- quite the contrary. But things change over time, and if we're to understand the way software actually is getting onto users' PCs, we have to be clear about what specific software is being tested.

    There are two types of p2p networks.

    1) The likes of bittorrent. You download from an authoritative server a 'control' file that has an MD5 checksum of a file you want. Very difficult or impossible to spoof the saved file.

    2) The likes of kazaa. You query other machines on the network for files and pray it's not riddled with spyware, etc. It's probably far too easy to create a virus, giving it an enticing name like 'xpcrack.exe' and plop it in your shared folder and wait for someone to pick it up.

    Why would the makers of kazaa bundle spyware/trojans etc directly into their application when it's easier to allow the user to search for something they want and have a hit not on what they really wanted but spyware masquerading as what they wanted?

    I've loaded kazaa on a sandbox computer and downloaded executable files pertaining to cracks of various kinds, and virtually all of them were not cracks at all but were trojans/viruses, etc.

    Bundling trojans/spyware into an application is slow, restrictive and pointless when there are so many more effective ways to do so, including activex, email worms, seeded trojans in the p2p network, etc.

    Kazaa itself and the multitude of files associated with its install for example is reported as spyware, but probably in the most generic term of the fact that whatever files are set up as shared are accessible and thus the program is considered "spyware" for giving that information up. If you go into its options and set up the shared directory, or what you want to share or not, it's not likely to divulge or give up any serious information or data.

    But I don't really care, because I don't really trust apps these days that don't have source code with it.
