Paul Vixie On DNS Changer: We're Dealing With Malware the Wrong Way

AlistairCharlton writes with this snippet: "Victims of the DNS Changer malware think they have better things to do than check their internet security, and as a digital society we're dealing with malware in completely the wrong way. These are the thoughts of Paul Vixie who worked with the FBI in intercepting servers used by a gang of Estonian hackers who made millions of dollars from redirecting internet users away from the websites they requested, directing them to advertisements instead." The linked article also offers an interesting description of how the FBI's quiet takeover of a botnet came to be.

  2. Definitely the wrong way by SJester · · Score: 5, Insightful

    I'm not sure why it's even the government's obligation to "close the deal" (from TFA) and help a victim fix their infected systems. If the victim felt they "have more important things to worry about" than prevent infection, then felt they "have more important things to worry about" than routinely scan their system, AND THEN when told that they were infected they "have more important things to worry about" than fix it themselves and pay out of pocket... maybe the government has "more important things to worry about", too. tl;dr If you didn't wear a condom, and you didn't get tested, and you found out you had syphilis and didn't care - why should I?

    Cornficker is related to the Conficker malware, but prefers to fick it's victims with vegetables instead. Many vicitms did not mind.

  4. Summary: Area Man Has Gut Feelings by Lord+Grey · · Score: 4, Insightful

    From TFA:

    Summing up, Vixie says: "These victims seem to feel that [they] have more important things to worry about. My gut feeling is that they're wrong, but I can't seem to prove it. My other gut feeling about all this is that we, as a digital society, are doing this all wrong."

    My gut feeling is that International Business Times didn't really have a useful article but needed some more ad space, so they wrote this thing.

    For the few of you considering actually reading the article: There is nothing new to see there. Move along.

  6. hack is brilliant technically, stupid tactically by circletimessquare · · Score: 3, Insightful

    why did the hackers think they were ever going to get away with it?

    it is a brutally effective hack, but...

    1. they thought no one was going to notice?
    2. and if they noticed, no one was going to do anything about it?
    3. and if anyone was going to do anything about it, they didn't see the glaring weak point that would so easily undo all of their hard effort?

    commandeer your rogue DNS server. duh!

    how come these hackers spent so much time energy and effort in a scheme so easily undone?

    this not a matter of "oh, it's easy to point problems in hindsight". these guys obviously had the intellectual capacity to think through the technical requirements of their hack. so they obviously had the intellectual capacity to think through the tactical requirements. none of them said "it will never work: single easy point of failure."

    "These are the thoughts of Paul Vixie who worked with the FBI in intercepting servers used by a gang of Estonian hackers who made millions of dollars from redirecting internet users away from the websites they requested, directing them to advertisements instead."

    well ok, jokes on me: they realized the weakness, and they bet the authorities were going to react slowly, and they won the bet

    Care to show a source, even a single one, for that? The FBI handled this right, asking ISC to install and run the DNS servers. I really doubt the ISC would play ball with any extra-legal requests for data.

      I appreciate the FBI intervention, it gave people ample time to upgrade their virus scanners and get it fixed - or go to the website that gave them tips on removing it and get it fixed... worst case they wound up with another piece of malicious software and had someone fix it in the interim. Being in direct to customer Tech Support, I was grateful that I did not have to answer a single call regarding this yesterday, and that would not have been the case had they just turned off those servers when they took this beast down. It would be interesting to see if the virus scanning companies saw an increase in installs/updates/upgrades since the mass media coverage last week.

      Exactly. We know we never have to worry about a private corporation using personal data for profit, right? And no company would ever play ball with the feds in return for a juicy government contract. And its a good things they have a good reputation. I mean, someday companies might even have to start hiring PR people and the like to try to hide the evil things they do behind a good reputation.

      Who said anything about a private corporation. Do you know what ISC IS?

      They are a non-profit organization whose sole purpose is to support the infrastructure of the Internet. They build open-source software (like BIND and implementations of DHCP). Sorry, but you really should research before you spout off.

      Not to mention running the F root name server. They really know DNS.

      Off the top of my head, I can think of only a few organizations in the world who have the know-how and ability to run a large-scale DNS system properly. ISC is at the top of that list. IMHO, the FBI chose wisely.

    Vixie predicts an uncertain future where computer users don't understand or simply don't care about the risks involved.

    As opposed to today when uhh...

    At what point did the average home user understand or care about security? We should consider ourselves lucky that service providers at least pretend to care about security these days. Any home user that can understand computer security policy and practice is most likely in the industry, or trained to do so.

    Now a High School / GED level computer security class might sound hilariously basic for someone on Slashdot; but might be as useful as drivers ed classes for the masses. Sure there are morons that will drive/compute unsafely no matter what training, but some basic learning on how to protect one's self would really help intelligent people that just don't know better.

    Wasn't this the original intent of the web browser? Rather than connecting your computer to a network of other PCs and running executable files, internet users would be able to set up "webpages" using a markup language that did not execute code on the computers of others who were only viewing the webpage. Drive-by virus downloads were not even possible back in 1995 or 1997 when web browsers actually "browsed" the internet. But browsing endless pages of text, sound, graphics, pictures, GIF animations and even motion video was not enough. Users wanted more interaction. They wanted in-browser games rather than playing stand-alone games in multiplayer mode. They wanted interactive web applications that could perform calculations, not just read back text and pictures like a magazine. Rather than standing against the demands of the uneducated masses due to the risk of anonymous cyber criminals hijacking their machines, HTML was enhanced with JavaScript, Flash and other exotic tools. The browsers made add-ons available and later these functions were buried and integrated deep within the next release of the bare bones browser. Like a boy crying "wolf" the browsers began warning users of the dangers of clicking a hyperlink, allowing cookies, allow scripts, leaving a secure site, certificate missing, etc. while at the same time very few of the websites users needed to see could be accessed without these warnings. Naturally the users began to dismiss most if not all of the automated warning notices. With time the scale and bloat of web browsers increased to surpass that of whole operating systems of old. Plug-ins, pop-ups, location sharing, data mining cookies, and notifications became standard industry practice. The malware hackers had endless fun with the complex, bloated, and vulnerable layers of code that left gaping exploits such that even a benign jpg image could become the carrier for a globally devastating virus. Hackers were even able to add malicious code to legitimate sites. Before long the intrinsically safe browser became the PC users most vulnerable liability.
