Open Source Software Hijacked To Push Malware 147

Posted by samzenpus from the malware-of-the-people dept.
jfruhlinger writes "VLC Media Player is a popular, useful, and free-as-in-beer piece of software. Unfortunately, its open source nature makes it easier for people with bad intentions to repackage it in nefarious ways. Not only do some of these folks claim that they're the originator of the software (a violation of trademark law and the license), but they often bundle it up with crapware and malware, which is a real dilemma for open source developers who play by the rules."

    this is entirely and precisely why distros such as debian go to such lengths to place GPG digital signatures on the downloads; why they go to such lengths to enact extensive GPG key-signing web-of-trust exchanges etc. etc. no software is allowed into the archive that is not GPG digitally-signed by someone who is part of the GPG web-of-trust network (thus whose physical identity has been identified MULTIPLE times by their peers including showing proof of identity in the form of passports or other physical but trusted identification document).

    the lengths to which for example the debian developers go are sufficiently extreme that it would be an incredibly foolish exercise for any debian developer to even attempt to place spyware or any kind of malware into packages, because they could be identified (via their GPG Digital Signature) and thus banned for life from the debian project.

    the lengths to which it would be necessary to go, to circumvent such a system, involve cracking of GPG Digital Signatures or of compromising the Debian Packaging system itself, and switching off the signature-checking system. whilst the average person would not know how to check that this had occurred, it is an extremely remote and unlikely possibility in and of itself; the experienced debian user could boot up off of a live boot or rescue CD and use rkhunter or chkrootkit to verify that the system had not been compromised.

    all in all it has to be said, in simpler terms (as many people on comments here have already said) - don't download stuff you can't trust! but if you can't be bothered to check, but are using a stupid operating system into which a package verification system is not built-in from the ground up, then don't use that stupid operating system! if you ignore this kind of advice, then you deserve everything that you get.

    The site that was promoting this crapware installer used the Mixxx name (trademark), several screenshots featuring the Mixxx logo and included a footer that indicated the contents of the page were copyright of their company 2008...

    So we tracked them down and sent them a cease-and-desist email for violating our trademark (misrepresenting themselves as authors and using screenshots which feature the Mixxx brand without our consent)... Simply put we told them they could NOT use our trademark at all, this mean no screens with our logo, no mention of the projects name -> this means to comply with trademark law they will have to alter artwork (covered under the GPLv2) and in doing so will be required rebuild the app and redistribute all of the code also. As far as we are aware they complied and now they are substantially less relavent from a branding perspective and no longer really much of a threat to our user community...
