    Silly me. I allowed myself to become involved in a battle of wits with
    someone who came unarmed.

    But, never let it be said I am not man enough to admit a mistake. And
    correct it! Sooooo..... PLONK!

    Excellent decision, sir. When you have nothing to say, perhaps it's
    best just to shut up.

    Now, back to defeating keyloggers. I contend that for any given acceptable
    risk, it is completely possible to defeat a keylogger attack. This
    is trivial if all you wish to do is authenticate or perform simple
    instructions. Less so if you wish to preserve confidentiality too,
    but still possible.

    or use a token with a protected authentication path (eg. smartcard &
    finread) for logging on, decryption, etc.

    If I need 100% protection against possible keylogger virus attack, so
    quite a neat thing I've seen was a "self-made" (self-programmed)
    mouse-keyboard so that you can "type in" your password/paraphrase via
    mouse so that a keyboard-hook doesn't work...

    Taliesin is on the right track. You must not type in your password at
    all. Let a program inject the password (internally) - there is no
    simulation of keyboard typing anywhere otherwise the keyboard logger
    will capture your keystrokes. That program may possible be an injected
    DLL (in the windoze world).

    There are lots of programs for that purpose, some free (e.g. Password Safe)
    and some pay-for (e.g. Personal Info Keeper).

    I never type passwords in anywhere, always drag/drop or cut/paste.

    Hi Joe,

    Good start but two potential flaws
    1) keyboard logger still has a chance of capturing your screen (of your
    original password document because it is in clear text)
    2) someone may overlook your shoulder.

    For more secure needs, search for password manager tools instead.

    That is NOT a keylogger, it's sumpn else
    Wouldn't get them anywhere - even if I didn't notice (unlikely)
    Thanks, but I don't have a problem. Save your advice for someone who does.

    password safe (free utility) never shows the password after day1 (first
    time you set up specific site) and stores password using blowfish on
    local machine, and requires a separate password to access the "safe".
    Security wise I have not tried to crack it, but for me it is a handy
    utility for storing login passwords for multiple sites. It has a
    reasonable random password generator (though only alpha numeric) for new
    sites. The password generator does not do special or alt chats, but the
    safe will support manual entry of those char types. The random password
    Generator will support user define password lengths which is useful for
    long password strings irrespective of the char type restrictions. One
    may add or modify a couple of the random generated chars with alt or
    special chars to further enhance the security of the chosen password,
    users call. Bear in mind blowfish isn't bulletproof,but meets casual
    encryption requirements for my local system.

    Another way to protect passwords from people looking over your
    shoulder is to use biometrics. I use Microsoft fingerprint reader
    and never have to type in passwords. Pretty cheap at $35.

    The Fingerprint Reader should not be used for protecting sensitive data
    such as financial information or for accessing corporate networks.
    We continue to recommend that you use a strong password for these types of

    Wonder if there is a Linux driver?

    My daughter opens my laptop fingerprint reader easier than I can. I
    recorded the prints and have rerecorded them, I have a difficult time
    opening device with my print but she just walks on in...Boy I hope she
    never kills anyone...

    The Microsoft Fingerprint Reader is primarily used for logging onto
    windows, accessing Internet sites that require a User Name and
    Password. The disclaimer with the Fingerprint Reader should not be
    used with financial sites, etc. is for Microsoft's protection from
    liability. The Fingerprint Reader is very convenient and easy to use.
    PGP is used to protect E-Mail messages, attachments, and files stored
    on the computer.

  16. Several years ago there was some tests in the German magazine C'T.
    I think one trick was to breathe on the sensor after somebody used it,
    that made the pattern 're-appear'.
    Have you had any success with things like that?
    And making a fake fingerprint with some silicone kit?
    Is there a Linux driver?

    Hi Jan,

    I guess that is a remote possiblity to counterfit my fingerprint. I'm
    not concerned, because my computer is in a safe enviorment.
    No Linux driver on my computer.

    It is generally trivial to "capture" soneone else's fingerprint, especially
    if one shares some environment with him (home, work, social, etc.). For
    instance, offer him a glass of wine to taste, or even just take his coffee
    cup - the imaginative will readily think of dozens of additional methods.
    BTW cyanoacrylate (crazy glue) can be used to lift even very faint prints.

    Most cheap (and even some expensive) fingerprint readers do not do very (or
    any!) "aliveness" tests - they just read the pattern.

    Moreover, many fingerprint readers are simple USB devices and do NOT
    authenticate themselves to the computer (or vice versa) - chances are there
    is no encryption of the data transmitted either. This makes it very easy
    to spoof a genuine reader, do replay attacks, etc.

    Nope, fingerprint readers, as currently implemented, are generally very
    feeble reeds on which to lean.

  19. I say, if someone wants something so bad they are willing to take
    your finger . . . I suggest you just give it to them.

    But if you give 'em the finger, they'll be really pissed off.
