MySpace Users Have Stronger Passwords Than Corporate Employees

Posted by Zonk on Thu Dec 14, 2006 03:36 PM
from the hardly-surprising dept.
Ant writes "A Wired News column reports on Bruce Schneier's analysis of data from a successful phishing attack on MySpace, and compares the captured user-passwords to an earlier data-set from a corporation. He concludes that MySpace users are better at coming up with good passwords than corporate drones." From the article: "We used to quip that 'password' is the most common password. Now it's 'password1.' Who said users haven't learned anything about security? But seriously, passwords are getting better. I'm impressed that less than 4 percent were dictionary words and that the great majority were at least alphanumeric. Writing in 1989, Daniel Klein was able to crack (.gz) 24 percent of his sample passwords with a small dictionary of just 63,000 words, and found that the average password was 6.4 characters long."

    So MySpace users are smart enough to pick somewhat secure passwords, but still dumb enough to fall for basic phishing attacks.

    It doesn't matter how strong their password is if they are still giving it to whoever asks for it.

          You're going to have trouble typing my password, as it's 6.4 characters long. The first six characters are 'passwo' The .4 consists of 'r' and 'd' type in such a way as to only use 0.2 of each. :-)

        From a link in the article:

        "The attacker had registered a MySpace account named login_home_index_html, meaning that the MySpace page hosting the fake login, looked like a legitimate place where users would sign on to the service."

        So it was just a user page but it DID have myspace.com in the URL. The URL was:

        http://www.myspace.com/login_home_index_html [myspace.com]

      Those corporate users that were dumb enough to fall for phishing had bad passwords. No suprises there. People prone to fishing are probably less securtity concious.

      Are myspace users really more security consious? Or are the typical demographics those people who tend to use oddball non-English words and text phrases that end up being "good passwords". yourmom69

              How is a password from sample A more secure than sample B when BOTH sample A and B's passwords were compromised?

              They were both compromised by social engineering. Which allows us to see the passwords people are choosing and find that corporate passwords are more venerable to brute force attacks.

          I never worry about passwords. I would not worry if someone else knew my password for slashdot. What would they do with it? The only thing they could do it make comments in my name. Even with my bank accounts the only thing they can do it to see how much money I have and transfer money between two of my accounts. If someone wanted to be super mean they could transfer all my checking account money into my savings account and thus cause any checks I write to bounce. They still would not get any personal gain from it. If passwords are such a problem let me suggest a hardware fix. Let there be two passwords. A local password that the user would remember and a password that would be sent out. There would be a table on either the hard drive or a usb flash memory card for the lookup of the secondary password. Since no one would have to memorize or even know the secondary password it could be a 100 randomly generated characters and could be changed every time the user access the account. If one uses the usb flash memory than one could take it with them for use on another computer and by removing it from the computer prevent any other user on that computer from accessing their account. If it is that big a problem than a fix like that would have been used a long time ago.

        Yeah I agree. The time limits on passwords cause most people to just come up with something easier to remember. Why should I have to change my password every 30 days if it's something like Mxo2s0LLn234aAZSQ If I can't even get it right I'm sure no one else is going to guess it. There shouldn't be a need to change it.

    You can't compare the passwords from two different phishing attacks. You only get the passwords from people who fall for the scam. If one scam is easier to detect than the other one, then one sample will contain passwords from dumber people than the other sample.

    The quality of passwords has nothing to do with the type of people that where scammed, but with the difficulty of detecting the spam.

    The only reason MySpace users have stronger passwords is because they're required to. Try signing up to MySpace with a weak password (i.e. without numeric characters) and see what I mean. I signed up for MySpace for a throwaway account with an easy-to-remember password, but couldn't.

    Computer security is something that kids are learning at younger ages these days. Case in point: My 6-year-old daughter plays a flash game called clubpenguin.com, which is basically a MUD where you're a penguin and you go around playing video games, socializing with other penguins, taking care of your pet, etc. Yesterday at school, her friend asked her for her login info, and she gave it to her. Yesterday evening, my daughter finished her homework, tried to log on, and got a message saying she'd been banned for 24 hours for cussing, and the time when her penguin was cussing was a time when she hadn't been on the computer. No big deal, but at age 6, she's now had a concrete experience that shows her how it's not a good idea to give your password to someone else, even someone you think you can trust.

    It depends on length and the character set.  Many cracking programs, brute force cracks, will iterate through all possible combinations of a character set up to a certain length.  This lets the program find simpler passwords faster.

    With just alphabetic characters and a 6 character length you have about 26^6 or about 308 million possibilities

    With alphanumeric characters and a 6 character length you have about 36^6 or about 2.1 billion possibilities

    Extending to common non-alphanumeric characters (using shift+#) adds another 10, 46^6 or 9.4 billion possibilities

    By comparison, changing the length of the previous examples:

    Alpha: 26^7 = 8 billion
    Alphanumeric: 36^7 = 78 billion
    Extended with non-alphanumeric: 435 billion

    So "crackability" as you dub it, is influenced heavily by the length of the password, but it is also greatly influenced by the character set used.

    As for whether "adklfjsldfjsdf" is harder to crack than "adklf123dfjsdf".

    "adklfjsldfjsdf" is 15 in length and alpha characters only (26^15)
    "adklf123dfjsdf" is 15 in length and alphanumeric (36^15)

    1,677,259,342,285,725,925,376 is less than 221,073,919,720,733,357,899,776

    So the alphanumeric one is definitely more secure.
