  1. Re:A good reason *not* to keep these things secret on Emergency Alert System Insecure · · Score: 2, Informative

    Here's security through obscurity:

    Frgw ocpw ap. a egmxugjt!

    You don't know what I said, but as soon as you figure out my algorithm you will. And you'll know what anyone else using that algorithm said. That's security through obscurity.

    On the other side of the coin, is SSH2 Key-based authentication. I can tell you exactly how that works, but that knowledge won't let you log into my computer. You need the key. That's real security.

  2. tornado sirens too? on Emergency Alert System Insecure · · Score: 5, Interesting

    I've always thought things like this were insecure. When I was in
    high school, I wanted to make a device to activate the tornado siren.
    I figured I could just implement a simple replay attack. I never got
    around to researching what frequency the signal was broadcast on, and
    I didn't know how to record the signal once I knew where to get it
    from. But it seems simple:
    record when they do the monthly test, replay whenever. Panic everyone. Good
    fun.

    Apparently if you modify various bits you can make them play different
    sounds and even broadcast voice. Plenty of fun to be had there.

    If anyone has done anything like this, I'd be interested in knowing,
    just so I don't have to get myself hauled off to jail trying to do it
    myself :)

    Yup, I have a fear of Wal-Mart due to a similar incident. I didn't steal anything but my new jacket set the alarm off (when I was walking in). They assumed that I, the fourth grader, was a huge criminal and let me know it. It still bothers me.

    This is a valuable lesson.

    Computer models can be WRONG. Computer models said that a 707 could hit the world trade center and not cause any problems. Guess what... it caused the buildings to collapse. (767s and 707s are pretty much the same... different electronics, but size-wise and fuel-wise, about the same.)

    That is very true. Since he said that his Quadro was $300 I can't imagine it was the best graphics card ever made :)

    But, my friend tells me that you can reflash certain cards (I think I can do it with my MX440...) to become quadros. And when you do, you lose many many fps in games.

    Different cards for different applications. Doom3 is not what a workstation is for.

    True, I suppose since I had a lot of stuff laying around (I still have 4 monitors...) that saved me some cash. That's what's nice about the x86/PC platform. Stuff from many years ago still works fine today.

    (That can't be said for, say, macs. Try using your ADB stuff today. Or your ADC monitors. Of course the A in all of those stands for Apple, which should clue you in. Thankfully today's macs use standard stuff. USB/DVI/IDE/PC2700 RAM, etc. )

    That's because the Quadros don't take shortcuts that fuck up the image like consumer cards do. You can't afford to have your diagrams munged to get some extra fps. Gamers can, so that's what their cards do.

  18. Re:embedding signiature?? on Hydan: Steganography in Executables · · Score: 5, Interesting

    Unless you do it like this (an example is always easy to understand).

    Say you have an executable:

    1337PROGRAM

    Your signature checking routine then does this:

    1_3_3_7_P_R_O_G_R_A_M

    and computes the hash

    deadbabeca

    And then sends:

    1d3e3a7dPbRaObGeRcAaM

    To reverse, we extract the hash (deadbabeca) and the "original" executable.

    Then we compute the hash (of 1_3_3_7...) and check if it matches...

    In summary, we embedded a checksum, but we removed it before we checked it. Simple, really.

    Gmail is a classic tradeoff. Do you want the convenience of having your email easily searchable and always available? Or do you want it encrypted stored on a DVD in your safe deposit box?

    Personally, I don't have anything to hide. But I certainly respect others that do, which is why I always encourage stego, strong crypto, and Freenet. If you really care, just PGP everything and you'll be OK. Don't trust PGP? Write your own crypto routines (they're pretty simple) OR use a 1-time-pad that you keep with you at all times.

    Anyway, yeah gmail is a privacy risk. But I don't care if someone knows that andy needs to meet me at 8:00AM at union station to have coffee... hell I just told you, you don't even need to read my email...
