Microsoft Secretly Beheads Notorious Waledac Botnet

Barence writes "Microsoft has quietly won court approval to deactivate 277 domain names that are being used to control a vast network of infected PCs. The notorious Waledac botnet is being used by Eastern European spammers to send 1.5 billion spam messages every day, and infect hundreds of thousands of machines with malware. In a suit filed in the US District Court of Eastern Virginia, Microsoft accused 27 unnamed defendants of violating federal computer crime laws. It further requested that domain registrar Verisign temporarily deactivate the domains, shutting down the control servers being used to send commands to the machines. The request was secretly approved by District Judge Leonie Brinkema, allowing the action to be taken covertly, preventing Waledac's operators from switching domains."

      If I wrote malware (I don't), I'd use google, other search engines and maybe even twitter (but that's probably covered by search engines nowadays) to search for new instructions :). So you could post the instructions "anywhere" in the world along with keywords. The search engines would find it. Naturally you'd check the signatures to see if the instructions are valid.

      I'd also write the malware in perl. Pretty easy to do such stuff with perl - can also fork and run the instructions in an eval (if you think people are going to crack your malware). It'll be interesting to see how the AV people cope with TIMTOWTDI. Probably trivial to whip up equivalents in python or similar.

      Well, here are a few thoughts:

      • Microsoft probably thoroughly reverse-engineered the botnet client code prior to seeking the court's assistance. Therefore, they have a very good understanding of the botnet's control algorithms. They probably derived those domain names and took those specific measures in response to their understanding of those algorithms.
      • For a botnet, hard-coding IP addresses could be riskier than DNS names. If someone is trying to shut you down, it's easier on their part to pick a specific set of IP addresses and (with cooperation of their respective ISPs) get them shut down or (without said cooperation) firewalled.
      • For a botnet, it's much faster and easier to change your IP address and update a DNS entry, leaving the botnet code alone. If you have to change those hard-coded addresses, you have to not only rebuild and push new code, but update every infected system (and any network admin on a legit controlled network knows that there can be issues with this). With the DNS entry they have a central point to update.
      • I'd not be surprised if Microsoft chose this specific botnet because it had a vulnerability that was within the reach of a court to address

      As others have pointed out, this teaches every other botnet author a lesson on what can be done. The problem ain't solved by a longshot, but maybe the Internet is safe for another night (cue Batman music).

      I tend to wonder at the accuracy of that assumption. I think that drug dealing is a lot like acting - people see all the famous actors and say "I can get rich as an actor", but don't notice that it is only the top one percent or so that truly make it - the rest struggle to get by, or make a moderate living at best. Additionally, as a drug dealer, you also have to avoid the law - being wildly successful for 5 years then getting caught and put in jail for ten to twenty makes flipping burgers more profitable an endeavor over the long term. Not to mention the rather short life expectancy of many of the most successful due to "competition".

      So, short term, yeah, dealing (or many types of crime) is easier than making money legally. But long term, you either have to be really good, and thus invest much effort in staying one step ahead of both the law and those looking to "replace" you, or you lose the advantage that crime had, and then some. And if you are investing the required effort successfully, you likely could have done equally well working legitimately. Sure, there are the Dons and Columbian drug lords that are the exception, but again - only the top 1% or less enjoy that privilege.

      Not a new idea. Google is working actively to stop this kind of abuse, which they do by forcing you to go through a captcha if you try to search for terms that are related to malware. I have taken apart a few "evil" programs that did google searches, and each time I found that the search terms had a captcha block.

      State of the art for malware is to use a generator function (typically a hash) to generate random domain names. If it loses contact with the C&C servers it will use this generator to try domain names until it finds a new configuration file (propperly encrypted and signed). For the controller they only need to register one of the domain names generated by the hash and eventually the bots will all reconnect.

They really didn't have any money left at the end of the week. Owning houses that you bought with drug money doesn't work out very well when the IRS comes knocking, so they would blow all their funds on consumables during the week.

      Eventually they got caught and spent about 5 years in jail each. But for the 2 or 3 years they were earning that kind of cash and spending it on cloths, cars, women and drugs they lived like rock stars. The problem is that you do get caught and it is a very rough life. You have to have a very low moral standard that most of society can't stomach. But from the pictures it looked like a lot of fun.

    It called a Temporary Restraining Order (TRO). In civil court cases, the Plaintiff can ask the judge to issue a TRO to prevent ongoing harmful conduct that later monetary damages after trial are insufficient to remedy. In other words: "Your Honor, this can't wait until the trial is over." The standards are high, and courts do not do this this without a very compelling set of alleged facts. Requesting Plaintiffs are often required to post a significant cash bond to cover damage to the enjoined party in case the TRO is not, in hindsight, the proper pre-trial remedy.

    In most cases, a court won't issue a TRO without notice to the defendants and a hearing to allow the sought-to-be-enjoined party to response to the Motion for TRO. In some situations, like this, where mere notice might allow the Defendants to further the harm, the court orders the TRO without notice to the enjoined party. The Order allows the Plaintiffs to demand third parties to do or stop doing something for the enjoined party - the first notice to them is when they can't access bank accounts, or their vendor refuses to cooperate, etc.

    The safeguards built into the system are (1) the cash bond, (2) a neutral judge that weighs the likelihood of irreversible damage and proof of the initial allegations against the harm from enjoining a party before a verdict, and most importantly, (3) that these are TEMPORARY. The judge will order a hearing with BOTH parties within (usually) 10 days of the TRO issuance, at which time the Defendants can object, rebut the Plaintiff's allegations, and ask the court to lift the injunction. At that point, it is a dispute between two noticed parties before a neutral court.

    Stuff is filed under seal in court all the time. The idea is that you don't want the defendant you're pursuing to know you're pursuing them if there's a high chance they can cover their tracks. You can't just make a "mere accusation" and get a court to do whatever you want. That, of course, would be silly.

    Most judges are really quite reasonable about the decision to keep things sealed. In any event, all the docs will become unsealed relatively quickly -- and if you think the court was *unreasonable*, that they abused their discretion somehow, you can take your complaint to the appellate court.

    Court proceedings are slow, but some crooks (especially intelligent, well-funded crooks) can move fast. This is the balance we've found between thinking things through carefully, and satisfying the public's right to this information, while still prosecuting agile crooks.

    In copyright infringement cases, the plaintiff would probably have a hard time convincing the judge that docs need to stay sealed.

    Believe it or not, the system actually works pretty well sometimes.
