Study Shows "Secret Questions" Are Too Easily Guessed 303

wjousts writes "Several high-profile break-ins have resulted from hackers guessing the answers to secret questions (the hijacking of Sarah Palin's Yahoo account was one). This week, research from Microsoft and Carnegie Mellon University, presented at the IEEE Symposium on Security and Privacy, will show how woefully insecure secret questions actually are. As reported in Technology Review: 'In a study involving 130 people, the researchers found that 28 percent of the people who knew and were trusted by the study's participants could guess the correct answers to the participant's secret questions. Even people not trusted by the participant still had a 17 percent chance of guessing the correct answer to a secret question.'" Schneier pointed out years ago how weird it is to have a password-recovery mechanism that is less secure than the password.

              You could always use the same answer for every question (regardless)

              From your bank:
              What was the name of your first pet? PASSPHRASE@bankdomain.com12345

              From your e-mail:
              What is your mother's middle name? PASSPHRASE@emaildomain.com12345

              From your favorite blog:
              What is your favorite color? PASSPHRASE@blogdomain.com12345

              Not easily guessable without prior knowledge of the pattern, but easy enough for you to derive as needed. Now, the question would be whether or not they forward-only encrypt the answer and verify it much like a password or if it's stored in clear text that any numbnutz with DB access could poke around. Hopefully it's treated as secure as a password, but I could see a lot of places not treating it that securely (which is probably mentioned in the articles that I didn't read).

If you look at a security as a bunch of security components put together either in line or in parallel, you'll realise that when you put in parallel something somewhat secure like a password and something not very secure like asking a question, then the system is only as secure as the weaker of the two securities. You don't need to know much about someone to know or guess where they were born or what their favourite TV show it, I mean that's the kind of information people put on their Facebook profile for the whole world to see to begin with.

      Not only that but when I have used them I've found them annoying as they're often case sensitive and it's easy to forget what you entered or how you entered it. What is your dog's name? Which dog? What is your date of birth? What date format?

      They're just bad all round, often the questions you get to choose from either fall into the category of far too easily guessed/socially engineered such as where were you born which 90% of people you've ever met can tell from something like your accent or where you work and live if you never moved away or they fall into the category of being too ambiguous such that when it comes back to remembering how you entered it 3 tries will probably get you locked out.

      Creating a list of questions that truly are secret and of which at least one is common to everyone is near impossible. You could start asking things like "Who at your workplace would you most like to sleep with" but I don't think most people would want to answer such intrusive questions!

      To be fair, most of the systems I have seen that have secret question type security don't let you in on the basis of the secret question, they email a replacement password to you, and only use the secret question to reduce DOS attacks and minimise the sending of plain-text passwords.

    Secret questions are only less secure than passwords if they tell you the password right away. But if they reset the password and email the new one to a pre-specified email account then just guessing the answer isn't enough; you'd have to have access to the victim's email account too.

    The questions have to be so easy that the owner will -never- forget them... That means they pretty much have to be a defining characteristic in a person's life.

    Favorite color, birth city, mother's maiden name, location of first job, favorite pet, etc etc.

    While my friends couldn't name a couple of those, it'd be stupidly easy for them to get those answers from me in a normal conversation. Even strangers, around friends, have a good chance at it.

    Also, my bank takes this a step further... Sometimes when you log in, it asks you one of the security questions after you put in the name and password. I've never felt this made much sense, but oh well.

    If someone was really wanted to go on a phishing expedition, they would open a site that requires registration, security questions, and all that, and then try the information on the webmail of the people who just registered. Probably would work phenomally as well.

    If websites wanted to be truly secure, they would ask for a mailing address or at least a phone number to confirm resetting things (thinking of financial accounts, not stupid forums). They confirm the same inane, easily duplicable facts in real life, but at least they have to reach you at a confirmed safe location.

      Well, that's clever, everyone should do that. I'll have to teach my grandmother to write perl scripts, then remember what she called it, where she stored it, and how to run it everytime she is asked one of these retarded questions. Oh, and also how to save the output to her gpg file after remembering what her gpg file was called and where she stored it and what its password is.

      If you (presumably) guard your passwords carefully (in this same gpg file?), why do you even bother saving the answer to the "secret question"? Just type a bunch of random keyboard characters (bang hard, using the opportunity to release the pent-up frustration), don't save it, and be done with it. Isn't that faster than going through the perl script rigamarole?

      For most things - various user forums, etc. - I don't give a damn about all this password/secret question paranoia. If they crack it, so what? I haven't changed my slashdot password since day one, its easy for me to remember, and if someone cracks it and "steals" my "identity" here, well, I would probably find it amusing.

      There are a relatively small number of things, such as bank accounts and trusted access to other people's networks (and yeah, my servers' roots) whose passwords I protect very carefully. Almost none of those things involve extra secret questions in case I forget the password, or if they do I've give a gibberish answer I don't save.

    I also use the book as a source for passwords for the many accounts I have everywhere on the internet. I spell out the login name in the book (say "Mylogin") by looking for the first word starting with "M", then the next word with "y", then the nex word with "l", etc... until I find a word that starts with "n", use the very next word that's 8 characters or more, append the line number, and that's my password.

    I usually remember most passwords I use all the time, but for the accounts I seldom use, the book title is the only thing I need to remember to recover my passwords. Given the size of my library and the fact that the book is a huge, boring French novel, tough luck even for a burglar to find it.

      Even worse, in my opinion, is some bank's web sites, like mine: It doesnt let me have a password of more than 8 characters, and special characters are not allowed (only alpha and numbers, not even space!).

      Then in the name of security, they put these stupid questions. Fix the passwords first anyone?

    I dimly remember I saw something like this on /. before...

    It's a no brainer. Or at least it should be. Most of those "secret" questions draw from a limited set of possible answers. Worse, ALL those answers will be found in a dictionary. Because they invariably ask for (*drumroll*) a real, usually English, word.

    Now, what do we tell people, what did we tell them for ages? DO NOT use words that can be found in a dictionary. Yet for the "secret answer" (which is in almost all cases as good as the real password) we ask for a word that can be found in one.

    Is it me or is this like, you know, STUPID?

    There is no "secure" word. Not even your pet's name. My first pet was called ;drop table *;, btw. Yeah, I'm such a geek... sorry 'bout your database, btw.

    • Is it me or is this like, you know, STUPID?

      Only if it is implemented in such a way that knowing the answer is as good as knowing the password.

      There's no reason it can't be used as part of a belt & braces approach (of course, if someone's stolen your belt then its possible that they've stolen your braces as well) and/or where the worst thing that it can trigger is to get a new temporary password mailed to your known address.

      It also depends what the stakes are and comes down to a risk analysis between the potential security risk vs. the inconve

  • When I have to fill out a "secret question" with an answer that's all too easy to look up, I just make up an answer no one will figure out but me. If someone trying to get into my account tries to guess what was "the color of my first car", how are they going to know the answer if I made up a word that doesn't even exist?
  • Just pick one word you use to answer all questions, like "love2canoo" or something. Why put in answers people can guess? Just make up a single answer that answers all questions.

    For example:

    1) Mother's maiden name: love2canoo
    2) First pet: love2canoo
    3) First car: love2canoo

    That way everyone trying to guess your answers will always be wrong. I'm not sure why people think they really need to answer those things truthfully. Lie, and others trying to use the truth will fail.

    Answering the actual question is obviously flawed security.

      Not filling them out is dangerous. If you don't fill them out then a question is selected by default. No answer is still an answer. A reasonable guess to 'the answer' is nothing, or rather, I didn't fill it out.

      I imagine an operator asking: What is your mother's maiden name? Then the perp being stumped, and after a period of silence, the operator determining that the question was answered correctly.

      And a machine is almost guaranteed to be that dumb.

    So, it seems every slashdotter is submitting his best SHA1 fancy trick to answer the security question. But I think you missed the problem. The problem is not securing the accounts of smart tech-savvy people, as they should already know how to do it themselves. It is "how do we make sure that Joe the Plumber, Granny, and Sarah do not set dumb-ass security questions leading their account to be pwned in less than ten seconds?"

    Schneier pointed out years ago how weird it is to have a password-recovery mechanism that is less secure than the password.

    Trump that: E.E. 'Doc' Smith pointed out sometime in the 1930s that what the world really, really needed was a foolproof way of establishing someone's identity. Unfortunately, his solution was to have some omnipotent aliens come up with a magic identity bracelet, which isn't particularly helpful.

    That's the real problem - these dumb-ass methods of establishing identities come about because there is no good solution on offer to let a service provider check that you are who you say you are - and no way do we trust our wonderfully tech-savvy governments or industries to set up and run one.

  • The only time I've run into these being used is as a second layer after they send a hashed URL to my email address, so the attacker would have to have known which email account on which server I was using, then discovered the password to my mail account or set up a MITM attack on my mail server, before they even got to the secret question part.

    i, too, have always deplored the secret question. so many sites force you to use them but they are really just insecure back doors into your account.

    my solution? for years i've been treating passwords and secret questions as two fields each, delimited by a non-alphanumeric. for example: say my mother's maiden name is "harris", i and i'm entering it as a secret answer on amazon.com. i would answer "amazon*harris". for passwords, i have a standard password, for example, "ninjasinmypants". at amazon.com, my password would be "amazon*ninjasinmypants". that way my password is different from site to site, but still easy to remember.

    add some password common-sense, e.g. not using dictionary words, and you end up with pretty strong passwords that are easy to remember.

    Here in Australia the Federal government department Centrelink (who are responsible for welfare, student support etc) make you answer a secret question every time you log on to their online system. Which is moronic as your user name is your customer ID you aren't supposed to give out, and they enforce strong passwords.

    Funny thing is that when you set a decent secret question you probably won't remember the answer over a year later (to clever for my own good). Of course their system is "smartly" designed and you can't get rid of your old questions just make new ones. So now I have about five questions I can't remember the answer to and twenty that are along the lines of "What is your name?" and I just hit refresh until I get an easy one.

    Remember folks if you make your security too tight people will just write their passwords on a sticky note and put it on their monitor.
