Rootkit Creators Turn Professional

pete richards writes "Signalling a trend towards increased 'outsourcing' of some elements of malware creation, worm authors are increasingly turning to commercially available rootkits to help their creations slip past virus detection engines. Those root kits in the mean time are becoming more professional. Antivirus vendor F-Secure reported last week that it had detected a first rootkit designed to bypass detection by most of the modern rootkit detection engines."

      There probably isn't a law against rootkits, and there shouldn't be. There should be a law against using them to break into systems that you are not authorized to enter, and there is a law against that.

      A law against rootkits would be very problematic. Is VNC a rootkit? If there's a bug in SSH that is exploitable to gain root access I bet it would suddenly fall under the domain of being labeled a rootkit by any law banning them, should the mainatainers of SSH be prosecuted because of that?

      It really comes down to liberty though. If I want to hack my own computer I should be allowed to do so. If I want to write a virus I should be allowed to do so, but I should not be allowed to release it into the wild.

    Hmnn, this article is thin on facts and figures. And like so much "news" coming from the security industry, you're never really sure how much of it is fud and puffery in order to sell new products. Still, I guess things will continue to get worse so long as much of the IT industry plays pass the parcel, a shuffling process that always ends with the hit landing up on the poor old end-user, the person who is usually least qualified to deal with it.

    I guess Bruce Schneier is right when he suggests that the way to improve some aspects of security, anyway, is by placing responsibility firmly on outfits like banks and ISPs who'll get smacked mightly hard in the wallet - by law, this time - unless they raise their game. That might put some pressure on OS-makers and their pals to design products that don't also need AV checkers that are dependent on signature libraries and prey to zero-day exploits.

    Love the quote from a researcher saying that the alleged sale of rookits means that "there is a criminalisation of the virus world going on." As if it hasn't been criminal till now, just good clean fun ho ho.

    Virus writers go by their own rules. The anti virus business has a reactionary approach. Unless the anti virus engines have the updated signatures they can't stop the virus from spreading.
    Doesn't this again bring up the question which was discussed a while ago. 'Why should Operating systems have a policy of default accept? Run programs only which you trust.' Not that this will solve the problem in one shot but it will make the problem more manageable. By the way things are going and the speed with which new viruses are created, i guess the day is not far when we will need huge databases to store the signatures for the viruses on each machine.

  9. Misuse of the term by $RANDOMLUSER · · Score: 5, Insightful
    From TFA:

    A rootkit is a tool that helps worm authors to slip past malware detection tools. The rootkit is 'wrapped around' the virus, and hides its payload from detection engines. After the rootkit has penetrated a system's defences, the worm can start doing its work.

    Wrong. A "rootkit" is a series of hacks to the underlying operating system, which make a running process harder to detect. In other words, a rootkit will keep your process from turning up in the Windows Task Manager, or a Linux "ps".

      Root kits will normally includ things such as modded ps and other modified binaries so that the system appears to be running fine, yet has a backdoor and any logging / system monitoring tools will not show any processes or activity.

      There is more to a root kit than just a replacement ps, but of course that is a critical element.

      No it's not rocket science, but in practice modding system binaries whilst on the outside keeping the system appearing to be running normally is much harder, different library / operating system / architectures to deal with and the fact that you are messing around with core system files.

      I think at this point the burden of proof is on you to come up with a reference. I've personally always heard the term rootkit used in the manner used now by about three people who have replied to you, and as described on three different fairly-definitive websites referenced in this thread.

      We can sit here all night posting back and forth "is not," "is too" but I don't think that we'll get any further. If you're so certain on your position please take 30 seconds and find something reasonably definitive to support your position.

      Mods - before modding anything else in this thread please take the time to actually look up what a rootkit is... :)

      For the record, an exploit is software designed to gain unauthorized access to a system. A rootkit is a set of tools used to maintain such access without the knowledge of the admin of the cracked system. Typically it includes modified ps, login/su/sshd, etc.

      The whole idea of a rootkit is to make sure you can get back into the system a week later when the admin has patched the original vulnerability. If you rm the ps command it probably won't take long for the admin to figure out what happened.

      The best way to detect a rootkit is via tripwire, run from a boot CD. There really isn't any way of defeating this method of detection, but it is very inconvenient since it requires brining the system offline for scanning. There are tools like rkhunter which search for rootkits on running systems, and in theory these can be defeated by a very clever rootkit.

      Not necessarily. There are rootkits which are based on kernel modules (so that the kernel API are not reporting the process either, just in case the sysadmin brings in a statically compiled ps, or manually digs through /proc).

      It's the primitive rootkits that only replace some common utilities such as ps, ls, and netstat. Many of these don't even bother to doctor md5sum or rpm, so they can be trivially detected by an rpm -qa --verify.

      The good ones on the other hand do a much more thorough job, and can only be detected by booting from a known-good media (i.e. a Knoppix CD)
