Washington Post Says Use Linux To Avoid Bank Fraud 422

christian.einfeldt writes "Washington Post Security Fix columnist Brian Krebs recommends that banking customers consider using a Linux LiveCD, rather than Microsoft Windows, to access their on-line banking. He tells a story of two businesses that lost $100K and $447K, respectively, when thieves — armed with malware on the company controller's PC — were able to intercept one of the controller's log-in codes, and then delay the controller from logging in. Krebs notes that he is not alone in recommending the use of non-Windows machines for banking; The Financial Services Information Sharing and Analysis Center, an industry group supported by some of the world's largest banks, recently issued guidelines urging businesses to carry out all online banking activities from 'a stand-alone, hardened, and completely locked down computer system from where regular e-mail and Web browsing [are] not possible.' Krebs concludes his article with a link to an earlier column in which he steps readers through the process of booting a Linux LiveCD to do their on-line banking." Police in Australia offer similar advice, according to an item sent in by reader The Mad Hatterz: "Detective Inspector Bruce van der Graaf from the Computer Crime Investigation Unit told the hearing that he uses two rules to protect himself from cybercriminals when banking online. The first rule, he said, was to never click on hyperlinks to the banking site and the second was to avoid Microsoft Windows."

        Countrywide had a nice system.

        I had to enter my user name, and then then the password screen came up, I would type in my password, and then click on one of about 40 images on the screen.

        I had to click the one that was my image (this was rather than a sign in button).

        Also, I think a security token can count as a second factor of authentication, and I agree on security questions, never help at all, and often I can't find options with an obvious answer (for myself).

          That's not two factor, it's one factor. It's something you know, in two parts. A key fob introduces something you have.

          A big problem with what you described is that 40 images to choose from is like adding one more character to your password, allowing lowercase, numbers, and 4 other punctuation marks only.

          It doesn't add much to security at all, in other words.

            As a victim of Identity Theft, I can tell you that banks and credit agencies just don't care. The bank writes off the loss due to fraud. The credit agency shrugs their shoulders at bad information in your credit file and tells *you* to fix it (while they happily go on reporting the bad information). In the case of stolen credit card numbers, the credit card company simply issues a new card and reverses the fraudulent charges. Meanwhile, the thief has their new television and the store is out a few thousand dollars.

            In my case, the credit card company opened a line of credit for "me" even though the online application contained the wrong Mother's Maiden Name. I only found out about it because the thieves put in for a rush delivery of the card and *then* changed the address on the account. The card wound up at my house instead of their house/drop box/whatever. The incorrect maiden name and quick address change didn't set off any fraud alerts. Neither did "me" trying to get a $5,000 cash advance on the card prior to activating it. And when I called them about it, they refused to give me any information because "I might run out and kill the thief and then they're liable." They even gave the police department the runaround.

            As I said, they just don't care. They'll do everything in their power to protect themselves. Even if protecting themselves in the short term means the identity thief gets away and commits more fraud against their business in the long term. In the end, you are only important to them insofar as how much green they can make off of you.

          True, but it doens't have to be that expensive to do right. My bank offers two different solutions for the second-factor. One is s crypto-key tokenthing that they send you to hang on your keychain. (so you log in with a password + a 5-digit security token from the gadget)

          The other is, quite simply your mobile phone. You enter your username and password, if correct, they send you a SMS with a 5-char one-time-password, you enter this and are in.

          Yes, it adds 10 seconds to the login-procedure, but it's a very efficient way of stopping keyloggers and malware from learning how to access your account. Even if they successfully snoop your password, that doesn't help them aslong as they can't ALSO intercept SMS-traffic to your cellphone. This isn't IMPOSSIBLE offcourse, but it sure as hell raises the bar.

        Those are both the same factor, just like a user's password.

        Security factors are

        1. something you know
        2. something you have
        3. something you are

        In order to qualify as "two factor", you must have two of those (no, having two of the same factor doesn't count.)

        So passwords, personal question, and favourite image are all examples of "something you know", and don't represent two-factor authentication.

        The Security-token would be an example of "something you have", and thus combining them with a password would be two-factor authentication.

        You realize that the way two factor security is supposed to work is that is requires you to know something and have something right? The way that two factor security is usually done from what I've seen is requiring a password that the client knows and a rolling code from a small device the client has. As long as a bank does not allow that same rolling code to be used twice it doesn't matter what kind of keystroke logging, mouse gesture capturing, or screen recording is used nor how fast it is sent to the bad guys.

        For you car enthusiasts, it's like taking the engine with you when you leave the car. Even if the car is hot-wired, it's not going anywhere without that thing you still have.

          Though I agree two factor authentication is useful, the 'taking the engine' analogy overestimates the difficulty of breaking through it.

          All the scammers have to do is instead of recording your keystrokes, gesturing, etc., they display a 'fake' copy of the bank to you through whatever software they have installed on your computer. They take the information you think you are sending to your bank (but are sending to them instead) and instantly have their scripts login to the site from their own systems (or some other bot on the net).

          If they prevent your initial login to the site from happening, they can use your username + password + rolling code themselves if their software auto logs in.

          This of course requires a user to go to a phishing site (miscellaneous.scammersite.com or something more complex), or requires the phisher to own the user's computer enough that they can intercept their connections & deal with the SSL certificate issues) while the phisher's automated software automatically goes to the real miscellaneousbank.com site.

        Because a 2 factor authentication token like an RSA key changes every 10 or so seconds so by the time Bad Guy #1 has finished parsing that log the 2nd authentication factor is out of date. The far cheaper way of doing this which most banks in Australia have started using is a one time password sent to you via SMS. This password works one time only (hence we call it a one time password, geddit) so if the Bad Guys(TM) get the entire password in real time and are reading their logs in real time then they still cant use it as the password has already been used.

          None of this will work with the problems described in the article, if someone has control of your computer then you're screwed no matter what kind of authentication you have. In one of the examples they specifically stated that crackers used the token code and delayed the customer's request:

          Johnston's bank requires customers to enter the code from a Vasco security token. But the thieves - armed with malware on the company controller's PC - were able to intercept one of those codes when the controller tried to log in, and then delay the controller from logging in. Indeed, Johnston said the company's computer logs show that the controller logged into the system while the series of thefts was already in progress.

          So, instead of the cracker getting blocked the customer would have been blocked because the "malware" made the customer's request come in AFTER the cracker's. If you were really clever you'd program the thing to intercept all the communication before it gets encrypted to go out to the bank and then fake the returned data so the user doesn't know that you're toying with them (yes, you can intercept the crypto library calls - I toyed with this some to get the Red Alert 3 Beta working on Wine). I don't know about you, but I can't think of a solid way around this interception (except having the bank only allow logins from a special custom browser that they load on a Live CD).

Browsers on LiveCDs don't magically download malware from the internet by themselves - you have to direct them to. And most conventional malware must install itself - which won't happen on a LiveCD.

You're going to extremes purely for the point of argument, but although it may have passed you by, it was established several thousands years ago that "nothing is certain".

        Browser security is only an issue if you're visiting other sites, in the same session, on the same boot, on your LiveCD.

        Wrong. Any security compromise on the same boot lends a possibility of compromising that session. Not all vulnerabilities will lead to that, but some can.

        And going as far as questioning whether your CD burning software is infected is ridiculous. You can't be any more certain that your mouse doesn't have imbedded circuitry tracing your movement pattens, or your keyboard doesn't have a keylogger built directly into it,

        No, the question is not whether the software came pre-0wned. The question is, once this practice becomes widespread, won't malware authors target the ISO downloading and/or CD burning process? If malware attaches itself to Nero, and Nero injects something into your shiny new livecd, what are you going to do? Ask it to verify itself?

      hey, who says your CD burning software isn't infected - implications on trusting trust and all.

      I understand there's only a fine line between safety and paranoia, but the idea of a CD burning software having been compromised to detect Linux LiveCD ISOs and add a software keylogger to the system included therein is so far up in 'paranoia' territory it already got full citizenship and is considering running for president against "Elvis is hidden in Area 51" and "9/11 was planned by Israel to draw the US into the middle east".

    Its not just "linux vs Windows" but "trusted boot": All you need to rely on is that the live CD is OK and your BIOS is not corrupted and you can effectively safely connect to your bank.

    I use it myself for my Schwab account, with the added bonus of there is enough math to show active traders lose big, so don't trade active, which goes into play here.

    Well, don't do online banking.
    Or, use a totally separate computer to do online banking. Only use the web browser to access one's bank account.
    Or look for those "freeze" type software, which makes the harddrive essentially read only.
    Also, it doesn't hurt to check which processes you are running, and whether any of those are unusual.

      You won't find the word "proprietary", "open source", or "source code" in the article. The reason Windows is advocated against is simple: Malware is written to target Windows. Malware could as easily be written to target any operating system which is vulnerable.

    The browser on a LiveCD may be out of date. How about a USB flash drive that can save your ISP settings and can update the browser? Banks could distribute them for the price of the flash drive as a safer option for online banking.

    Devil's advocate here:

    Of course, a diskless system running Linux would reduce the chance of malware on clients, but perhaps if a company is dependent on Windows, almost as good security (and I state almost) would be obtained from denying admin access and using something like DeepFreeze, Windows SteadyState, or similar?

    Combine DeepFreeze with AppLocker, some decent enterprise antivirus utilities, BitLocker, and the usual physical and BIOS protection on a machine, and one can make a decently locked down terminal that can cleanly run Windows apps. Should additional software be needed, no need to install it, just use something like VMWare ThinApp and have it runnable from a central location.

    There is nothing wrong with a diskless system and booting from a CD-ROM. However, unless one creates a custom image with reliable enterprise level auditing tools, it becomes difficult to extract data from a group of PCs (and this is important for larger businesses come tax season, or regulatory compliance), and it is definitely an issue to add or update software without a reboot, unless it is a precompiled binary on a central server that people run.

    Also, instead of running live CDs, why not consider going to a vendor like Wyse and going with truly thin technology? This way, there is little to no fiddling with the client side. If a thin terminal has a problem, just swap it out for another one, chuck the old one in the RMA box and be done with it. This is arguably a lot easier than the cost for maintaining standard PCs [1].

    [1]: I'm primarily intending enterprise level here. For some SMBs, it is a lot cheaper to go with a boot CD and a generic PC, but for larger companies, it may mean more futzing around with stuff for their IT staff, especially on the scale of thousands of endpoints. If I had a startup with a call center of 5 people, PCs are a lot more economical. However, 500 to 1000 people in a non-technical call center, then I'd take a serious look at thin terminals and a beefy internal network fabric.

      Yes, a hardened single-purpose Windows machine is almost as resilient as a Live CD. Almost. It is also infinitely harder to set up correctly and significantly less useful all those times you aren't banking. It is understandable why it is not the solution recommended for non-technical users or people who only want one computer.

    ...it's more a matter of a read-only medium. If people start doing this is greater numbers, all the evil people will do is start distributing hacked ISOs pretending they're legitimate. This also doesn't do much for machines which have been hacked at a BIOS/bootloader level. In fact, if the PC is set to boot to the hard drive and the trojan supervisor is smart and puts up a boot menu that looks bios-ish (ie, allowing you to select the boot device), 95% of users would never notice. So unless Linux LiveCDs start running checks to see if they're being virtualized, this isn't a very good safety net.

    Also, honestly, how many people do you think check the MD5 sum on an ISO? Hell, I've never had a RedHat/Fedora disc that passed its self-check. I gave up on that ages ago.

    A bank with any technical savvy would be immediately preparing a LiveCD/USB distro that boots as quickly as possible into a browser pre-configured with the bank's portal page set as the home page. The distro would contain nothing extraneous -- just enough for fast, safe banking. It would, of course, be thoroughly branded, but completely legit vis a vis source code and license notices. Give them away in the mail, or even sell USB drives.

It's difficult to convince non-power-users to drop a bank and go with another that works in Konqueror or even Firefox.

    But the banking system here, requires the use of single use numbers for each online banking transaction. Your bank provides you with a unique sheet of them and if you lose it, you have to request a new one. Nor are credit cards popular with German consumers. Sites such as Amazon.de allow payment by bank transfer (Uberweisung). You can manually complete the transactions slip and give to your bank or do the same thing with your online banking. Any issue and the transfer has to be reversed. There are an awful lot more banks too - one just around the corner from me and at least three within a few minutes walk with real people working there and very, very friendly managers - if you're liquid!
