Malware vs. Anti-Malware, 20 Years Into The Fray 62

jcatcw writes "Steven J. Vaughan-Nichols considers the dissimilarities between malware of yore and current infiltrations as we approach the 20th anniversary of the Robert Morris worm. Modern malware apps curl up and make themselves at home in your system, where they wait for a chance to snatch an important password or a credit card number. Welcome to the era of capitalist hacking. Any self-respecting malware program today is polymorphic, making signature-based antivirus approaches difficult. Heuristics and virtual sandboxes offer alternatives, but all such methods are reactive. Unfortunately, monitoring lists and networks is about the only current alternative."

    Some malware i've seen has become seriously soffisticated, so much so cleaning it is basically impossible.

    Non-admin rights, client-side file-scanners, web-side black-lists, and user training is the only way malware is going to go away.

      not only that but a more varied OS/software environment would lessen the damage that could be caused by malware/baddies in general. homogenization is likely one of the worst things to have ever happened to software in general.

        Only if we don't unify our code, which probably won't happen because people will want to target broad user bases. When code can be compiled on a Windows machine to target a Linux machine, you still have problems.

    Don't install system wide untrusted software, only use signed software from your public repository or from trusted vendors.

    Prevent any other changes from being made to the system, mount system partitions read only.

    Where users are installing software, force it into a sandbox (one for each application). Each sandbox will have limited access to the network, user files and hardware (such as web cams and microphones).

    The simplest solution is to never allow software from users to run (mount home partition as no-exec). However, this doesn't cut it much of the time, which is why I would suggest doing something similar to no-exec, but as a sandbox rather then not running the file at all. I'm not sure how hard that would be, but I'm sure it is possible.

    (Oh wait, are we talking about MS Windows here? I guess you can ignore what I said then...)

          For PCs in a home environment, would you recommend criteria that shut out software developed and self-published by a micro-ISV [wikipedia.org]?

          I don't know of any tool similar to System Restore Points from MS Windows in GNU/Linux land, but dd could easily do a similar job.

    Between spam, malware, and credit card fraud, the criminals are winning, big time.

    The eventual consequence of this is a faltering of trust in our financial systems and economies, and the rise of new kinds of criminal mafias, with billion dollar portfolios. If you thought the mob was scary, wait until you see what rises out of the ashes of the current system.

    The solution to this, I believe, is first to limit the information transferred in any transaction to that which is necessary for the transaction (no grocer, you don't need to know where I live); second to implement electronic cash (in the current credit card system you give authorization to perform transactions at any time in the future without verification); and third to establish and teach strong cryptography for communications, transactions, and identity.

    But the biggest thing we can do now is get the world's police forces to get off their asses. As long as these things are not prosecuted, criminals will flourish, and they are.

    It's time to make this an important issue in elections, before we all lose big.

    The whole way security is treated needs to be changed. Having root and an ordinary user just doesn't offer the level of granularity that users need. As a user I want to be able to do everything on my computer, what's really needed is fine grained access control per program. Of course, that has issues with users having to grant those privileges but you could have profiles. Imagine installing Evolution or something and it pops up and says "This software says it's a mail client, does that sound right to you?" and then what privileges it gets granted will be set by a "mail client" profile already installed on the system.

    When you need to install something esoteric then you would have to do some more advanced steps but if you are installing something strange then you probably know what you are doing anyway.

    This could maybe be combined with some sort of trust network. Say your friend installs something that needs non-standard access rights, they could grant the required permissions and create a new profile. You would have them in your trusted list and would have access to all of their profiles so when you install that application, it can categorise it using the info your friend provided.

    I think this system provides a good balance between really fine grained permissions and not blindly clicking through loads of confirmation dialogs.
    • That sounds good, but I don't think the average user has the patience for a system like that. I know even as an IT guy it would get a little old. And unfortunately I don't trust the software venders to come up with an effective automated system that would lessen the required user intervention.

      • The way I imagined program access control was that each user program would be confined to a sandbox where it only had access to its application directory, a (system configured) data directory for that application and basic OS API functionality. If an application wants network access, it can request it from the OS and the OS will ask the user whether to grant the application the access it seeks. The user could be informed by the system what the implications of granting access would be. It could prompt a sing

    In re: "Unfortunately, monitoring lists and networks is about the only current alternative."

    There are many alternatives to this, starting with: "Recognize that operating systems which are readily compromised by malware are broken and not acceptable for use." If you choose to use an OS which is so intrinsically weak that it cannot survive exposure to the (unfirewalled) Internet without anti-virus, anti-spyware, anti-adware, etc., then you have chosen poorly, and no subsequent choice you make will compensate for that.

    A followup point would be "Understand that it is not possible to 'clean' a malware-contaminated system. The only acceptable course of action is to wipe to bare metal, reinstall, and restore from backups." While it might have been partially true in a limited sense that some malware could be removed by anti-whatever products, that's certainly not the case now: it's much more likely that malware will evade detection and removal. Of course, it serves the purposes of both anti-whatever companies and lazy system administrators to continue propagating this fiction, because if they actually had to scrub and rebuild systems as often as they're infested, they might have to face some hard choices that they'd rather not.

    And an excellent set of auxiliary points may be found in Marcus Ranum's The Six Dumbest Ideas in Computer Security [ranum.com], where he enumerates the most egregious (and sadly, most common) mistakes made by nearly everyone, including supposed "experts" with strings of meaningless, worthless certifications after their names.

    So there are plenty of alternatives -- but choosing them and implementing them requires vision and insight, two qualities badly lacking in many in the profession.
