Storm Worm Botnet Partitions May Be Up For Sale 192

Bowling for cents writes "There is evidence that the massive Storm Worm botnet is being broken up into smaller networks, and a ZDNet post thinks that's a surefire sign that the CPU power is up for sale to spammers and denial-of-service attackers. The latest variants of Storm are now using a 40-byte key to encrypt their Overnet/eDonkey peer-to-peer traffic, meaning that each node will only be able to communicate with nodes that use the same key. This effectively allows the Storm author to segment the Storm botnet into smaller networks. This could be a precursor to selling Storm to other spammers, as an end-to-end spam botnet system, complete with fast-flux DNS and hosting capabilities."

      Basically, you set your records to expire in a very, very short time, and constantly change the DNS servers, as well as the records. This makes it very hard to shut down the DNS, since its always moving and changing. I guess a good way to picture it is if at google, every single one of their 1M servers was changing. IE, every 5 seconds, a different machine was the dns server for "Google.com" and the www address changed to a different computer. Then, try to figure out which machine was misbehaving, and displaying the wrong data. It would be difficult.
      • ...and if there aren't, then why are reputable DNS servers allowing these super-fast changes to DNS records anyway? Certainly such trends can be easily detected and stopped dead in its tracks?
        • Sure there are legitimate reasons to do this - one of them is cheap datacenter fail-over. If I have web servers colocated in two different datacenters with two different ISPs, and one of them goes down, I can change the TTL on my DNS records to, say 30 seconds, and point all the addresses to the other location. The short short TTL will cause global DNS to be updated much more quickly than normal, and my web site's traffic won't dead-end.

          On the other hand, I defintiely see ISPs that don't respect DNS TTLs
          • Ok, but I think the original poster's argument is, the DNS servers that normal consumers connect to (ie. supplied by DHCP when connecting to your ISP) shouldn't normally be receiving lost of responses with very short TTLs.

            Is this another one of those things an ISP *could* do to help control this scourge? Could they reject all DNS responses with a TTL below some threshold, even if its 29 seconds, and not break legitimate access? Or keep those responses in the cache and flag/reject follow-on responses if

            Changing the TTL when you need to change the records, won't make any difference. Those nameservers that already have cached the IP addresses of your machines will have cached the old TTL also. Those nameservers that need to look up the IP address will pick up the new IP address irrespective of the TTL.

            It really only makes a difference if your domain's TTL is short before you need to make the change.

            Actually you'll have to change the TTL prior to failing over. So if you use it for active fail-over and not for scheduled maintenance, the other nameservers will be using your 'old' TTL. A common mistake by cheap webhosters.

            The other issue is that TTL is a suggested time for keeping your records alive. The other (caching) nameserver can choose to ignore it (to circumvent stuff like this botnet or just to keep it's own load down) or if it can't reach your nameservers after that TTL you specified it will just

      Here's a small and possibly unrepresentative datapoint from last weekend that would tend to suggest there are a lot of infected PCs out there, some of them with Storm. Basically, 2 of 3 PCs scanned had backdoor trojans and I didn't have time to debug the third PC enough to scan it.

      I spyware scanned three PCs belonging to two friends/family households. Naturally, they were all Windows. I used Webroot Spysweeper which is pretty good but costs, and Kaspersky online scan, which is good but slow, and virus only.

      - PC 1: infected with various spyware and a backdoor trojan (remote access by the bad guys) - had an up to date antivirus (AVG) that didn't spot any of this, but no anti-spyware installed.

      - PC 2 (same network as 1): couldn't even install new software (error on running any new .EXE), ran out of time to debug this so did not install Webroot or any other tools. Also had AVG antivirus, which was up to date, and no anti-spyware. Presumed infected.

      - PC 3: (2nd household) - infected with a different backdoor trojan and several viruses. Had Norton anti-virus that had not updated since 2004.

      I would assume the average Windows PC has a high chance of some sort of infection, unless the users are very careful about installing third party software, some of which carries spyware or worse, and clicking on links in IE. Even Firefox had spyware on one of these machines.

      Windows PCs run by power users (not the users here) can be somewhat secure, but it's painful to make them so. One colleague who's very techie still got infected by a PDF security hole recently, so you need Secunia PSI to run continuously, as well as monitoring some security blogs, and updating software regularly, as well as using a good anti-spyware tool, not using IE/Outlook, etc etc. However, once you are making this much effort, the work needed to install Ubuntu becomes much less of a hurdle - you might as well just switch over one PC so you have a safe PC for online shopping/banking etc.

      The only good thing about this story is that nothing very important was being done on these PCs - little online shopping and no online banking... however, that's the users' self-reported status and they may well not want to admit they are at risk.

      I don't do this for a living, I'm just a Windows and Linux user who wondered why there were so many popups on one of these PCs and ended up getting sucked into this when I should have been socialising - fortunately anti-spyware scans can run during dinner...

Every computer I've seen with an up to date Norton, McAffee, or any other 'major name' anti-virus is just chalk-full of trojans and spyware. Way over the FDA recommended amounts. I usually run Spybot once to clear out the easy stuff, and then go registry hunting with HiJackThis and a few other tools.

    The updates are part of the Slashdot tenth anniversary auction. In addition to the @slashdot.org address and low user id, CmdrTaco has also gotten the operators of the Storm Worm Botnet to auction its use off as part of the charity action.

    Some potential uses for the winning bidder:

    • No longer will you have to only imagine having a Beowulf cluster of those.
    • Create your own Slashdot effect at the push of a button.
    • Thousands of Slashdot sock puppet accounts at your beck and call, ready to mod you up, karma-assassinate your foes, or post supportive replies to all the drivel you post.
    • Bring the parallel power of distributed computing to bear on problems like cracking DRM, modelling global warming, or ray tracing pictures of Natalie Portman with hot grits.
    • DDOS the RIAA / SCO / Diebold / whoever and become an instant Slashdot hero.

    There's only one way that there'll be enough public outcry to cause solutions to be generated. The spammers will have to overplay their hands hugely. (Think Al Qaeda in Iraq - things are turning around over there at the grassroots level, mainly because AQI was chopping off people's heads and serving roasted children on platters to parents, and the public outcry has been enormous.)

    Everyone hates spam, but spam filtering techniques have progressed to the point where we're at an uneasy stalemate with spammers. Everyone hates DDoS attacks, but in truth, how many people have really been the victim of one, and how many companies with muscle are really vulnerable to a normal-sized one? What will have to happen is that some overambitious crook gets it in their head to attack a Google or a Level3 or an Amazon or a national military, and puts the muscle behind it to make it work. It'll take players of that sort of weight to induce ISPs to do what they should have been doing all this time - proactively detecting botnet traffic and suspending the account of any user, individual or corporation, participating in such botnets.

    I suppose we could also black hole enough of the world that the botnet controllers are forced into the reach of countries with tough computer anticrime resources, where they can be put behind bars and well out of the reach of any keyboard. I'm just not quite sure the Russians will stand for that....

    I'm sorry, I'm probably sounding completely lame to those more firm in cryptography, but I have to ask:

    What would it take to attack the 40 byte key? Imagine a coordinated effort by the biggest 500 gouverment computing setups around the world. All the blue genes and whatnot pitching in. The Japanese sure have the one or other state-of-the-art mainframe supercomputer, and CERN, ESA, Nasa and few German weather services have a few aswell. There is tons of horsepower laying around idle at agencies, bureaus and the occasional school or corporation. If they all pitch in in a coordinated brute force attack *and* have Seti@Home do a few hours too it should be possible, no? Especially if one takes into account that at least the NSA has mathmatical functions that do some of the dirty work and speed up the process a little. They wouldn't even have to publish them.

    Wait, let's just check:

    255 to the power of 40 is rougly 1.8 times 10 to the power of 96 (Gulp!). Thats nearly Gogol. (10^100, what Google initially was supposed to be called, the guy registering the domain mixed up the letters...)
    Whatever.
    On it goes: For the sake of ease I'll roughly estimate that after the overhead has been dealt with, half of the top 500 (or a simular setup) will be doing optimized attacks on an average of 50 billion tries per second. An average state-of-the-art mid-range server has aprox. 20 GigaFLOPS, so I think that's fairly realistic for a large mainframe doing a multi-step operation.
    250 * 50 000 000 000 = 1.25*10^13 tries per second.

    *60*60*24 makes 1.08*10^18 per day. [Sidenote: This may be way off wack allready and total bollocks but it's fun actually]

    *7*52*5 makes 1.96*10^21. Oh, gee. This doesn't look to good. Where at it for 5 years and have only covered less than the fourth root of our total amount of keys. Even if we had 10 times the power it would make up only 1 percent of the keypace. Sheesh. We'll probably be cheaper off in handing out Linux PCs to everyone on the planet.

    It's no use. I gotta start working on my next project: Finding an explicit function for prime numbers. Hehehe. I could use the Million from the Fields Medal too. :-)

    Bottom line: My question/assumption was lame. But at least I found out myself. :-)
