Superfish Security Certificate Password Cracked, Creating New Attack Vector 144

In a followup to today's news about junk software included with Lenovo computers, an anonymous reader writes Robert Graham at Errata Security has published an article announcing his success in extracting the SuperFish self-signed security certificate from the adware which has caused Chinese computer manufacturer Lenovo such embarrassment in the last day. Since SuperFish is already capable of carrying out man-in-the-middle attacks over secure connections on the Lenovo machines which use the certificate, the disclosure of the certificate's password presents hackers with a 'a pre-installed hacking environment' which would be difficult to arrange by other means. The password, "komodia," is also the name of the Komodia Redirector framework, which allows its clients to manipulate TCP/IP network sessions "with a few simple clicks."

  • I mean, even without this, they were performing man-in-the-middle attacks on their customers. Doesn't something like the DMCA apply when you're hijacking banking websites?

      Of course they can be sued. Can you actually win? Probably not. I would assume there's some agreement somewhere when you unwrap the computer saying you accept the software that's installed.

        If the law sees it that way then you need to start selling to businesses and include small print that says "by accepting these goods you sign over all property, goods, chattels and monies under your or the accepting company's ownership, stewardship or control to us without let or hindrance from the date and time noted".

        The court then to remain consistent would need to ensure that this small print is held to be equally valid ...

      • Small claims court- You don't need to pay a lawyer, you can just present your side of the story to a judge or jury
        Worst case scenario, you lose half a day and get nothing, and spend ~$100 on court fees.
        But there is a chance, especially with a jury, that you will get reimbursed the laptops cost, and either way Lenovo will spend thousands of dollars in legal fees.
    • Think of it like this:

      Every computer you own has security vulnerabilities. Huge ones. Right now there are zero-day vulnerabilities in Windows that we don't know about. Same with Linux. Even OpenBSD probably has some remote vulnerabilities in there (though not many).

      If you could win a lawsuit based on vulnerable software, every software company would go out of business.
  • But then I always wiped my Lenovo to install Ubuntu anyway.

  • Now that the vendor knows this, they may be legally obligated to do a "voluntary" factory recall or face a government-mandated involuntary recall.

  • so, we have a for-profit load of a known attack system with name = password from Lenovo.

    what was the trade name of this series of laptops, GOTCHA? "New, the GOTCHA from Lenovo, because we want your other financial information, too." great tag line. when do the TV ads start?

        Why do you assume that Dell, HP or Acer would be any better than Lenovo?

        If they are not doing the same, they soon will be. Even if they did not want to do it for moral reasons, the market and capitalism will force them to or risk losing revenue.....

        And even if we do sue them and win...they will just come back with 2 new methods to do the same, only this time a little more careful not to get caught.

        • by cfalcon ( 779563 )

          Well, there's the fact that Dell, HP, Acer, etc are NOT doing this. That, I feel, is a pretty good indicator.

          It's clear that many companies feel obligated to bundle shitware, but that doesn't make it inevitable nor ok. I think it's a good indication that Lenovo is alone on this branch.

      • I mean, it's important and all, but there's different levels of issues. Heartbleed and shellshock are one thing- this is a sketchy manufacturer doing something sketchy.

        Did you miss the part about how this software breaks the whole certifcate validation process? This is worse than Heartbeat for anyone who has an infected laptop. Any HTTPS website can masquerade as another HTTPS website and, because of the way Superfish works, the browser won't detect anything wrong.

        • by cfalcon ( 779563 )

          It's worse than other bugs for anyone who has an infected laptop... but to get an infected laptop, you'd have to buy it from Lenovo and then not purge the disk promptly. It's not an issue because most people aren't ever going to have a Lenovo laptop, nor a bank who uses one, nor a common website that relies on it. Amazon isn't going to lose your credit card number because they run Lenovo laptops or whatever. Unlike the actual real bugs that cause problems, this one is just something that blights consume

        Couldn't agree more, the only time I ever used a Lenovo was when it was handed to me at work. Look's like a pregnant brick, weight's more than a pregnant brick, and generally suck in all ways considering the pricetag. Besides, I ALWAYS format a new laptop, drivers are usually out of date when it lands in your lap, so you may as well DL the latest ones and make a clean start.

      I was setting up a PC for a friend yesterday and needed to install a popular shareware archival app that has been recognized as the best in its category and has never been bundled with any crap.

      I opened up Firefox and typed the name in the search bar which had Yahoo set as the default search provider - as Firefox have notably done recently. I clicked on the first link that appeared, which for all intents and purposes appeared to be the link from the actual creator of said application.

      But in fact it was not. It was some sleazebag site which basically bundles a load of crapware into the installer. Even when I carefully unselected all the crapware it was trying to profer, it still installed a PUP IE addon that Malwarebytes picked up. In short, Yahoo has descended to the level of pushing shading companies which install malware on people's computers and hijack the installers of legitimate shareware products. And Firefox have descended to making this company (Yahoo) their default search provider.

      This is total shit. The model of the Internet as some kind of enhanced TV experience which tracks everything people do and targets and infiltrates them has got to stop.

      You are totally right in seeing that there is no qualitative difference between what corporations are doing, what governments are doing, and what scammers are doing. We have moved from an age of true innovation to one of scamming. Hence why banking and investment are so big.

    • Anybody else work in IT and is starting to get depressed?

      Starting to? Been going on for a while, for me. But it isn't the computers nor the internet which are rotting away it's the companies behind it all -- and the Governments which the companies run!

The other manufacturers are all watching to see how much backlash there is, and how quickly people forget and move on to see if this is something that they'll want to do in the future as well. Consumers won't care about this, and business will carry on as usual soon enough.

      If by "OS" you mean the factory-installed crypto-signed firmware/bootloader/OS stack which can't be changed without keys the end-user doesn't have, then the answer is "probably more than we would like to think."

        I'm not sure what models you're referring to. My last three or four laptops have been Lenovos, and I never experienced any roadblocks installing Linux on them. I think the BIOS on at least one of these supported a whole-disk encryption but that doesn't even try to prevent you from reformatting and installing an OS.

        My vague understanding is that Superfish is Windows software, not part of BIOS or the Windows bootloader, and certainly not grub. You can also apparently uninstall superfish: http://www.cnet.com/h [cnet.com]
