Fears of a Conficker Meltdown Greatly Exaggerated 143

BobB-nw writes "Many have been worrying that the Conficker worm will somehow rise up and devastate the Internet on April 1. These fears are misplaced, security experts say. April 1 is what Conficker researchers are calling a trigger date, when the worm will switch the way it looks for software updates. A 60 Minutes episode about the worm on Sunday will stoke concerns. But the worm has already had several such trigger dates, including Jan. 1, none of which had any direct impact on IT operations, according to Phil Porras, a program director with SRI International who has studied the worm. 'Technically, we will see a new capability, but it complements a capability that already exists,' Porras said."

    The Media...? Exaggerating?

    that never happens.

    /Here, have some cool aid.

    • Mainstream media isn't exaggerating it, they've barely mentioned it. It's the on-line media that can't quit talking about it. How many Slashdot articles?

          Yeah, that was a sham job.

          Script: Leslie's Virus Story

          Software Guy's office:

          Leslie: "There's this thing called a worm out there that's going to steal all your money and destroy the world, you know, it'll be bad. Cats and dogs lying down together and all that."
          Software guy: "Buy our software or your bank account will be emptied. Please watch this sham demo."
          Leslie: "Wow, I got a Facebook from Andy, let me just go ahead and delete that..."
          Software Guy: "No no no no no!! You have to pay attention to Andy or your money won't be stolen."
          Leslie: "I see. So that's why nobody's had their money stolen yet. You're not just on the show to sell your software, are you?"
          Software Guy: "Nah, you can trust me. I'm a software guy, not a banker. But if you don't buy it, some Russian kids will get all your money."
          Leslie: "Is there any other way to protect your computer, like installing the latest Windows patch?"
          Software Guy: "You're really not good at playing along, are you."

          Cut to interview with woman who's money was stolen because she didn't have Software Guy's latest product:

          Woman: "I saw it transfer money from my account to my son's account right before my eyes."
          Leslie: "Really? Right before your eyes."
          Woman: "Yeah."

          Woman's password is clearly visible on Post-it note on monitor. It's "password".

          Leslie: "So you have virus software?"
          Woman: "Yeah, it came with the computer. But after 30 days it started asking me to renew the subscription for $30, sooo..."
          Leslie: "I see. Did you consider a Mac?"
          Woman: "I'm not cool enough for a Mac. If that hot, skinny redhead isn't cool enough for a Mac, what chance do I have?"

          Virus Expert's office:

          Leslie: "What does this cornflucker thing do anyway?"
          Virus Expert: "Well, nothing so far, but that could change. One day it's going to take all your money and destroy the world. It's going to be bad. You won't believe what the cats and dogs will be doing."

    April 1st is when the worm will *start* looking for updates. It will continue looking from that date on, with a different set of domains each day. So there is no reason why the authors would register one of the domains and put out an update on the first day. If anything, they would wait a while to increase the number of domains security researchers have to watch out for. Also, the authors may not have any reason to update it just yet - it seems to be quite successful in its current iteration. They may be waiting for a buyer to purchase a block of the botnet for example.

    Maybe I'm wrong here, but doesn't it make more sense to get everyone trying to fight this virus/bot/whatever early rather than wait?

    After April 1st, this thing will be drawing from more domains than can be blocked for future updates. It sounds like it'll be much more entrenched and difficult to combat if that happens. So this advise sounds a lot like 'Well, the gangrene has spread from your foot up to your knee, but it's not a problem'.

      Maybe I'm wrong here, but doesn't it make more sense to get everyone trying to fight this virus/bot/whatever early rather than wait?

      They're trying. Microsoft has released a patch that supposedly blocks the primary vector [microsoft.com] (a vulnerability in the Server service affecting all Microsoft operating systems since Windows 98), and updated their repair tool MSRT [microsoft.com] to detect and remove it (download it from a machine that's not infested). It has probably removed it from several million of the estimated 15 million infested machines. Microsoft is working with ICANN [icann.org] to block registration of the generated domain names in the case where they're not yet registered and the owners of the domains that were previously registered to mitigate downtime. Every managed service provider and major IT shop I know of has pushed out all of this stuff. Unfortunately, this is not even close to enough. The secondary vector, autorun, is pernicious. This thing is now on the root thousands of major shares and every time they remove it one of the thousands of Conficker clients puts it back. It's on millions of pen drives, millions of backups. It's been burned to millions of CDs. It's on iPods and mp3 players, Blackberries and iPhones and Windows Mobile phones, picture frames and DVDs. It's probably now in the root of DVD ISOs distributed via all the popular media distribution sites. Tertiary vectors include compromising network neighbors. Your grandchildren are going to be installing this thing if they don't figure out the whole "autorun is stupid" thing.

      This thing is really very well engineered. The next one will be even better. And the next one better still. If you're in a Microsoft shop you're going to be working half your holiday weekends for the rest of your career, and a lot of planned vacations too. Remember that this is not the only Windows malware currently making the rounds. There are at least three major development groups and all of them have active botnets and a release schedule for new exploits.

      We've been playing this game for a long time and the black hats are getting more proficient than the white hats. The problem is that the target platform - Windows - cannot be made invulnerable to these threats without defeating its main selling point: application compatibility. Most of the people who work with this toxic stuff do their development on BSD, OS-X or Linux and refer to Windows boxes as "targets". If Microsoft makes Windows so secure that this junk won't spread, most of the apps for it won't run. You might as well run an OS that's not a target now as wait for that to happen.

      But TFA is right. April Fools is the day the botmaster begins to harvest his crop of bots. May 22 is more likely the beginning of operations. I could be wrong about this because I previously guessed January 16.

    I would like this thing to actually shut down all those computers that are infected. It would save quite a bit on energy and actually be quite useful. If there would be a way to permanently disable a computer (flash it's BIOS with a bad image) then maybe it could stimulate the economy. Another thing would be to simulate a 56k connection on all those machines. Finally the intertubes would be cleared of a lot of clutter by people trying to get to awful flash 'movies' of random people on Facebook or MySpace. Another thing would be to register every IP that the computers are connected to as potential spam hosts to well-known spam registries.

    Of course if some host is infected and some life or death situation is dependent on it, the blame should be placed on the IT administrator or the vendor, not the creator.

    It will be interesting to see what will happen.

    Ok... so here's what I don't get:

    Security experts are well aware of this botnet client and are keeping a close eye on it. They've picked the client bot apart line by line. They know exactly how it is supposed to behave on the client side, but they of course don't have a clue about the server side. So why can't they hijack the hijacker?

    For example, say this client bot is programmed to go to IP address on April 1st and DL some update. Ok..., block that IP address on the internet or trace the IP address back to the owners and stop it there. Those don't seem hard. (ok... and before someone calls me an idiot for saying "block the ip address on the internet", what i mean is that you can get the major service providers, certainly here in the US, and potentially abroad to "lose" anything sent to a specific address.)

    Ok... so let's say that the client bot is programmed to go to IP address to and ping each one to ask for an appropriate update, verifying each update against a specific hash key. Ok... then grab IP address and put in something that DLs a file that neutralizes the bot. There can be no hash key that the researchers can't figure out because they can pick through the entire client bot's code bit by bit.

    I'm clearly not getting something crucial here, but it just seems that in all the moaning about how bad this is that it wouldn't be that hard for someone person to write some kill code for it as long as enough time and effort had already gone into understanding the client side code.
