Worm Transcodes MP3s To Infect PCs

snydeq writes "Kaspersky Labs has discovered malware that inserts links to malicious Web pages within ASF media files, posing a danger to Windows users who download music files from P2P networks. Infected files launch IE and load a page that asks the user to download a codec. The download, a Trojan horse, installs a proxy program to route other traffic through the PC. The malware also has worm-like qualities, according to Secure Computing. It searches for MP3s, transcodes them to WMA format, wraps them in an ASF container, and adds links to further copies of the malware, all without modifying the .MP3 extension."

      This is really clever. That way of using the file container to get the user to download false codecs.

      I wonder if it could work with other wrappers, like AVI, Quicktime, etc. Maybe not in their original state, but with slight modifications that could fool the player.

      I wasn't aware of all the capabilities of the ASF wrapper, but that sure was a ticking time bomb.

  3. Data vs Program by mlwmohawk · · Score: 5, Insightful

    Microsoft has a SERIOUS design pathology. They too often confused "data" with "program." Every G.D. thing in Windows can, in some way, initiate an action. This is a problem.

    A "music" file should be data. E-mail should be DATA! This is absolutely crazy. Making everything capable of being interpreted as programmatic content is at best a security flaw.

      Computer users (yourself included, me too!) have demanded more automation,

      Speak for yourself. I don't want "automation" and most of my family and friends get confused by it, "Hey, why is it doing that?" is the typical response.

      they want less user interaction, thus MS and everybody else will develop for these wants.

      You are confusing "wanting it to work" and "automation." Clicking, or double clicking, on an icon in a window and having the correct player pop up and play the file correctly is what people want. That is, in fact, *all* they want. No one asked for media files that would "automate" anything.

      User's don't even understand computers at the level where they could ask for such a thing. If they did, they wouldn't even ask. I submit that much of the push for programmatic content within media is from the *IAA types looking to extend control.

      I remember when email was just that data!, had to uuencode/uudecode anything binary

      There is no reason why an email message has to contain programmatic content for an email program to be able to properly decode an attachment. That's what MIME types are all about.

    My question is how the hell that works? Why is it even possible to do that!?

    Data comes in, gets split into an audio stream and a video stream. You look at the magical tags and figure out which decoder to fire up. Feed compressed data into the decoder, get decompressed data out. Pass the video data to the display pipeline, and the audio data to the audio pipeline.

    There should be no way to execute anything from those pipelines.

    I hate how Windows has hidden file extensions in every version since XP. It's supposed to make the machine more Mac-like and friendlier, but it is a serious security concern.

    I try to turn it off on every machine that I'm asked to setup or fix, but occasionally I get someone who deletes the "unfamiliar" file extensions from their files and ends up not being able to open them.

    The irony is that in all these years, I don't think I've ever seen WMP successfully find and install a codec it was missing. I just end up with a message saying it couldn't find the codec that doesn't even tell me which codec it was looking for. Then it turns out this all just another malware attack vector.

    In 2000, this problem would have "more of the same" but the fact that this still exists in 2008 is insane. I mean Microsoft publicly admitted their security is awful in 2000, took four years to make a decent attempt to correct things, and yet here we are four years after that...

    Where did concerts come into this?

    GGGP wrote "support music by buying from the artists" which then led to a comparison of alternate methods of supporting the artists, ergo concerts. A legitimate (OT) point, and not a straw man. However, between the venues, concert promoters and TicketBastard, the concert business is ripping off artist almost as badly as the recording labels.
