Instant-Messaging Attacks On the Rise 151

Posted by CmdrTaco from the no-shock-here dept.
Ant writes "CNET News.com and ZDNet News report that security attacks over instant-messaging (IM) networks became more prevalent in 2005, according to a new study. MSN experienced the largest number of IM security incidents in both 2004 and 2005, while year-on-year incident growth rates were largest on AIM."

    I have not seen any such attacks when using my normal IM software. I am constantly connected to AIM but I never recieve such problems. It might have to do with the fact that I use Fire/iChat, or Kopete/Gaim.

    Maybe because my IM client doesn't download and run activeX ads I don't have such problems. The AIM client for Windows doesn't like running in restricted user modes or restricted IE settings on any machine i have installed it on.

    So I would say it's not so much IM problems but more of the same IE/ActiveX security issues that continually plague the world that uses that crap.

            This seems overly broad. How do you automate internal file transfers with a policy like this? Do you have no operational systems that need to provide data extracts to analysis systems or the like? Or do you allow automated transfer in documented and approved situations?

              That's the policy. Then exceptions are written as needed. This is pretty easy as there is a difference between a ftp between two OpenBSD servers and somebody accepting, by default, whatever crap anybody on the net throws at their IM client.

            However, GAIM seems to ignore (or unable to set on the server) the setting for "ignore everyone but my buddy list" on ICQ. In both Windows and Linux, you can set this, but it resets within a short period of time.

            Anyone have any ideas? Googling doesn't seem to indicate that anyone else has this problem.
    • Your assumption that these security are IE/ActiveX related is completely flawed.

      I am a WinGaim user and I have seen a large number of infected AIM profiles and away messages as well as received quite a few "click this" type IMs. The vast majority of these attacks are social attacks. Generally, the malware inserts a "click this" type link that tries to get you to "look at my pictures" or something like that with a link to pictures.gif.pif.

Why should they care that the picture came from an untrusted and unsigned source?
        • What makes you think that ".gif.pif" is any better? The dialog calls the file "a program". Even if a user knows that .gif means it is a picture, who says they know that .pif is an executable and not some other image format? Besides, the only time Windows truncates the extension is when you have "hide extensions for known file types" enabled (the default) and if this is something you don't know anything about then you've probably never seen .gif and don't know that it is an image anyway.

    IM applications are hot attack vectors.

    1. Most instant messenger applications are client dependant. You need YIM/AIM/MSNM clients to talk to others on those IM networks, unlike client independant networks such as IRC.

    2. IM programs store contact lists much like a standard email client. Easy to read, exploit and spread.

    3. Most IM programs enjoy a high degree of popularity. Higher user counts = faster spreading.

    It's probably why I avoid IM programs like the plague.
    • While it may be a hot attack vector, I don't see why it's an infection problem in the corporate world. Everything depends on the user being able to download & execute the payload. If it's a home user, there aren't may protections in place to save them. In a corporate environment, downloads should be filtered to begin with.
