Are Cell Viruses A Real Threat Now? 72

Posted by Zonk from the reach-out-and-cough-someone dept.
Celpha writes "According to security firm F-Secure, a Trojan virus (Cardtrap.A) attacks Symbian mobile phone operating systems, attempting to infect users' PCs if they insert the phone's memory card into their computers. From the article: 'We expect to see more of this on the mobile front,' an F-Secure chief research officer said. Trend Micro issued a media alert stating it is a 'fully functioning' mobile threat. However, Antivirus firm Sophos slams the claim of this first example of a serious mobile malware threat as just plain bonkers."

    TrendMicro claims that the Symbos_Cardtrp.A trojan is a "fully functioning threat", while Sophos dissmisses the entire thing as "bonkers". I'm thinking that the truth is rather in the middle.

    The Symbos_Cardtrp.A trojan is one of the first clumsy attempts at this sort of thing, but we all know that the malware only gets more sophisticated and polished over time. People certainly should be alarmed about the appearance of this trojan...not because it itself is all that threatening, but because it clearly demonstrates the potential for mischief.

    As Raimund Genes, president of the firm's European Operations, said: "This attack is really a proof of concept and may be an indication of a new type of blended threat to come." You can bet that as cellphones become more sophisicated and more interconnected to our computers, malware authors are going to turn this into a genuine threat.

    In short, while it's rather sensationalistic to tout this as a "fully functioning threat", claiming that there is nothingto worry about disingenuous in the extreme. Sophos' claim that paying attenton to this threat distracts sysadmins from the "real threat" of attacks on Windows desktops is pure sheepdip. Imagine if we dismissed out of hand the new threat of infection via USB thumbdrives, because we were all too busy paying attention to the "real threat" of infection over the network?

      An objective observer (which the various anti-virus people probably aren't) might ask why a mobile phone needs to become "more sophisticated" in the first place. My phone was a freebie about four years ago when I signed up, and still has way more features than I ever want or need.

      Give me a good phone book feature, voice, text messaging and some sort of answerphone if I can't take a call. I don't need it to be a low quality digital camera, hard-to-use PDA, sub-standard web browser, trivial calculator, poor-capacity MP3 player, pathetically quiet alarm clock, and all the other junk. Nor do I need it to run some super-complicated operating system that's ripe for attacking.

My points are that: 1) The statement's inclusion would imply that only Windows systems are theoretically vulnerable to this sort of threat, which is untrue. 2) Its true meaning, which is at best implicit, is that the only noticable development of these viruses will be on Windows systems. This is painfully obvious anyway (as there are so few viruses in general for other systems). Ergo, it's a trivial point.

      But when the new phone had to go in for repairs, I briefly re-activated the V60. That was a pleasure.
    • the trouble is that cell phones use digital signal processing to do their thing. They contain enormously powerful processors to encode and decode voice and even some radio functions are now done directly in firmware. Therefore, the user functions are really just a trivial add-on to the phone.

  • Got paid to develop Trojans (Score:5, Interesting)

    by Anonymous Coward on Friday September 23, 2005 @09:00AM (#13628692)
    I got paid by a major company in the mobile field to develop Trojan horses for Java, Symbian, PalmOS and Windows Smartphone.

    The goal was not to release "in the wild" but to showcase the need for funding for mobile phone security.

    Nevertheless, pretty much nothing has been done even though modern smartphone OSes are incredibly close to allowing excellent OS security (MMU enables kernel / user separation).

    It's pretty easy to do fancy stuff once you get in the mindset of an attacker. Like waking up the phone at midnight to place calls to a premium number. One doesn't even need to stack-smash to have fun (that is harder on ARM platforms bc you have to develop your own shellcode anyway).

    The problem is especially important for wireless operators because people pay with their mobile phone. While that is the basis of revenue, it also enables major fraud (very much akin to what the "dialer kits" do to modem owners by silently ringing 900 numbers).

    Examples:

      * There's a WAP (wireless browsing) service where you can download ringtones for $2. What if a program on your phone starts downloading those silently?

      * In some countries SMS are charged with a premium. What if a program are sending premium SMS without your knowing?

    Of course it's also important for users ("what if a Trojan posts my phone book to some website", "what if a Trojan gets my location from the network and gives it to my wife". It's also important for security that the phone not be transformed into a jammer by changes in the radio firmware / software, but that's harder to do.

    Hopefully the players involved will wake up before we find a nasty one in the wild.

    Cell companies would make cell phones that didn't rely upon such an exploitable OS.

    Granted Symbian is nice, looks pretty, but everyone I know with a cell phone running Symbian also complains that the phone is so slow to respond.

    All the old Nokia phones were extremely fast, responsive (no 3-4 second lag waiting to go back a screen just to look at one freaking phone number) and best of all, didn't require such an exploitable OS because at the time, it was all hardware logic-control.

    I don't know what the OS is on my Kyocera Phantom phone, but even it's slow to respond to keystrokes, and it doesn't have all those little capabilities that most phones nowdays have.

    Simply put, as long as phone companies use software instead of hardware to control a phone, there will always be a threat of software infection.

    Flash implements a full program language, but the program's wings are clipped. Unlike regular executables, a flash program can't interfere with other programs and it can't mess with files it doesn't own. Add a way allowing programs to interact with other components (including the file system) with a strict and manageable protocol, and there's no big need for any program to run unrestricted.
