LovSan Clone Let Loose

JMullins writes "According to Kaspersky Labs the LovSan virus has been re-released in a new form that has changed the appearance of the worm. It looks like the outbreak continues to get worse and worse, with no real end in sight until people can patch their systems. Net slowdowns are expected over the weekend when both versions of the virus start their attack."

      Maybe some of them do do that, and the A-V firms haven't caught on yet.

      Seriously, IMO the kind of worms we've seen so far are child's play compared to what we can expect when someone wants to do some serious damage. In the future we'll have stealth worms that just flip a few bits on your system and then erase themselves after propagating to another computer or two, worms that work as a genetic algorithm to optimize effectiveness and continually feed new variants into new "ecological niches" of the internet, worms that are mathematically optimized for the fastest spread, or conversely for the broadest under-the-radar spread, etc.

      The future is bleak, IMO.

      Uhm - they've been doing that for years. Early types were called polymorphism, an idea pioneered by the 'Dark Avenger'. Search for "MtE Dark Avenger" on the net. Old stuff.

      Basically, the concept is that an encryptor is built up in memory randomly, while the inverted code (e.g. add vs. sub, rol vs. ror) is built up in reverse. The virus is encrypted with the encryptor, and the decryptor is prepended.

      There were a ton of them in the early 90's. There are polymorphic Word viruses that use different techniques - running their script through a randomizer for variable names and such. Some viruses have also mutated their own opcodes as you suggest, although it's less common - but its been done.

      Detecting such viruses is challanging, but usually there are static bytes with known (although possibly variable) distances between them. One can also run an interpreter over a file and pseudo-execute it until it can be proven that it is or is not a virus, or just blast any existing crypto around the body and look to see what's there. If the virus just flips between equivalent opcodes, then just scan with a regular expression that includes each equivalent as an alternative. Another method is analysing the opcodes - if an exe's entry point is at the end of the file where you have a 1k decryptor right before 2k of garbage, and all the decryptor's opcodes fall within what one virus can produce, chances are....

      There are a lot more complex and hybrid techniques for it -those are just a few that can be described quickly.

      The French intelligence services work very closely with French businesses.

      And, to be fair, US intelligence service works occasionally closely with US corporations (there were some cases related to airplane industry where EU was investigating how come US company had found out what some european company was bidding).

      Point being that perspective certainly matters, like you say, but also that few government agencies if any are completely above using illegal and/or immoral practices to help "their" companies, anywhere in the world.

      Open democracies, and especially free press lessen likelihood of such stunts (by retroactively uncovering them, usually leading to scandals... which act as deterrent in the long run). Unfortunately those 'antidotes' are being threatened especially in US, by latest legislations (from "Patriot" act to DMCA).

      Oooh man, tell me about it. I don't know what I'm missing, I suppose.

      I had been working on my CAD system on my home machine running WIN95 and DOS. I wasn't even aware anything was amiss until I logged onto Slashdot to see whats new. I was wondering why it was so slow. My firewall responded in a bit and told me I was getting a helluva lot of connect attempts on port135. So, I go look up the log file and it looked like SQL slammer all over again. Almost a megabyte of infection attempts. I wondered at first if I had made an enemy on a dialup??? In 4 hours??? Why did the whole world seem determined to wax me off the web? Damm, it seemed like everyone in the world was wanting my port135.

      Ok.. so I continue to read Slashdot and the story finally loads about this new LoveSan virus making the rounds. Hmmm. When I think of how much work would have been lost had something came in and messed up my machine, I shudder. But then, I don't run my machine wide open to the net. I try to practice secure techniques - such as never allowing any programs to run that I have not verified their intentions, and don't run anything that allows embedded executables ( read: javascript and later things post DMCA that haven't been "cleared" by what I consider trusted groups - which are mostly the groups the DMCA was aimed at in the first place. )

      Sure, there are a lot of websites that I can no longer see. I can not even access the Southern California Edison site, nor many business sites - as they require these embedded-executable technologies as a requisite to viewing their content.

      So, I sit here, with a pretty fast system, as its pretty simple. I have no virus scanning going on, as I am not running just anything I get in. I do have an integrity monitor running, which does a quickie on startup to see if any critical files are amiss ( it just calculates an MD5 on my key executables and compares to what they should be. ).. if so, booting to GUI is aborted and I drop to DOS to straighten it out - but its never happened outside a test situation.

      I keep getting all these people telling me I should upgrade and be current with the times. I would gladly upgrade if the later stuff was actually better and more robust than the earlier stuff - but thats not what I see.

      Oh yes, the "presentation skills" are definitely better on the new stuff, but I see the new systems much like a stunningly beautiful secretary that I can't trust, and spends a helluva lot of time doing her makeup.

      I try to tell these business people what they are getting into by running software that hasn't been verified for trustworthiness, but they seem happy to go ahead and do it anyway as long as there is someone else to blame if things go amiss. I hoot till I'm blue in the face about these businessmen who put content on the web that can only be viewed with proprietary readers, whose underlying trojan motives, if any, can no longer be legally ascertained as a result of the DMCA.

      I am especially puzzled by business's perception of proper etiquette. Would they hire a sales rep that constantly interrupted a customer in mid-question with comments on his grammar or spelling? Or worse yet, rudely hangs up on customers if they don't understand something? Is not a corporate web-site their sales-rep in cyberspace? Why would a business hire such rude representatives that coin their own protocols and chide the customers relentlessly for not adhering to their latest incarnations of the communications protocol "standard"?

      At the risk of redundancy, I'll say it again. I do not like these proprietary unverifiable protocols. I consider them very risky - to me. I really don't care if YOU get hit with a virus, but I don't want any part of it.

      Ok.. I just had to get this off my chest. It might cost me a bit of karma, but I had to say it in public in the hopes that someone in management that makes the decisions will hear my plea.

    OK - maybe this is a -5 Flamebait here, but here's a couple of my thoughts.

    The desktop world is ruled (by numbers, anyway) by Microsoft. Any potential malware s'kiddie can knock together some malware in a few hours, dump it into some unsuspecting newsgroup somewhere or email it to his Outlook-using mates and start an epidemic relatively easily. The sheer number of vulnerable machines makes that easy.

    The installed base of Windows boxes also means that, despite MS not opening up their code to anyone (except governments and universities willing to sign away their first-born as insurance against breaking the NDA), large numbers of people spend vast tracts of time throwing McValue Meal-sized URLs at web-servers and mutant packets at RPC interfaces.

    Lots of people x Lots of time x Lots of machines = lots of vulnerabilities found...

    Now consider *nix. It has a number of advantages straight off the block:

    1. It's open source. Code that finds its way into the kernel goes through the best peer-review system available; public scrutiny.
    2. Generally, the people who run *nix are more tech-savvy than an average Joe Blow.
    3. Any vulnerabilities that are found get acknowledged and fixed very quickly.
    But what would happen if *nix had the sort of desktop penetration that Windows does? How quickly would the kind of person that thinks a computer case is called a 'hard drive' apply a *nix security patch? If *nix was that popular, how many more people would devote vast tracts of time to finding obscure security holes and vulnerabilities?

    Just a thought. Now flame away ;)
