How the Secret Service Cracks Encrypted Evidence

tabdelgawad writes "The Washington Post offers this writeup about how the U.S. Secret Service uses a Distributed Network Attack program to crack encryption on computers and drives seized as evidence. How can brute force still succeed with 256-bit encryption, you ask? Customized password dictionaries from the seized computer's email files and browser cache: People still use non-random passwords."

      We have determined that you are using an insecure PIN, because it has a pattern in it.

      Through extensive research, our staff has determined that many PINs are insecure because they contain patterns, birthdays, anniversaries, etc. By excluding all combinations of duplicate numbers, keyboard-pattern entries, and significant numbers, we have determined that the most secure PIN you can use is 7439. Please change your PIN to 7439 immediately in order to ensure our company's assets are properly protected.

      I work in the custom luggage industry. Most combo-lock mechanisms that I see are 3-digit. Yes, you can get locks with more digits but three is most common, (which is why I put "(most common)" in my post - maybe you missed that part? I kinda doubt that since you quoted it in your reply). But to answer your question; No, I don't believe there is a number shortage in Sweden at present. They are probably just conserving and planning for the day when there might be an actual number shortage. (Don't ask; it's a Swedish thing :).

      Also, keep in mind that most luggage has these things called 'handles'. If a thief really wants your stuff, they will grab it by the afore-mentioned 'handle', take it home, and drill the fucker open. IOW, luggage locks are only there to keep the honest people honest.

      Another thing: here in the States, you aren't allowed to lock checked baggage anymore. Airport screeners require that luggage be left unlocked to facilitate spot-checking of baggage. (Don't argue with this or you may well be labeled a terrorist.)

    I have a friend that works as a defense contractor and he has a security clearence and all that. His job is to build the radios that the FBI, Secret Service, etc use and if you think that stuff is paranoid, these guys are nuts.

    The radios are encrypted (obviously) using NSA techniques. The NSA techniques cannot be written down anywhere, and to find out how they work, they ask some dude who has been employed by said defense contractor for his entire life and his job is to remember this technique without ever writing it down or such. He is well paid too.
    Once this said technique is written and tested to work 100% of the time, and not 99.99999999% like many programs, it is compiled and the source file is then given to the NSA for safe keeping/code review.

    The radios themselves are the height of paranioa. The radios if tampered or left unguarded for 15 minutes, it will automatically wipe out the flash card (thus destroying the encryption key and non hardware based technique). This makes the radio a $1000 dollar brick which then needs to be sent back to the manufacturer to work again. (for a nice profit too!)
    Also, once a radio is compromised, the other radios are distributed new encryption keys, so their communications are now secure. The radios in said group are also re-keyed at normal intervals.

    Now, these radios if compromised are not totally useless. They can be used as remote listening devices (transmit when button not pressed, and "other" features) and can be broadcast fake information(duh).

    Also, in those type situations, I have another friend who says the destruction method of choice for paper and tapes are incendiary grenades. Load the classified manuals(these are just lit with a lighter, but you get the point), important computer chips and other stuff into a box, place the nade and watch it flame and then after it has burned, chuck it off said airplane.
    Also, most of the memory devices have a self-wipe feature. For hardware, the sledgehammer method is used. "take one, and apply liberally"
    After that, to break the individual chips, smaller boards are collected in boxes and smashed with said hammers and stepped on etc.
    He said his training instructor said, "Have you ever wanted to trash a room like a rock star? Leave nothing intact, and just destroy everything in sight? Except instead of some hotel room, it would be millions of dollars of equipment, and you get to destroy it? Nothing off limits? This is your chance. Live your dreams.
    Just before you land, make you sure you destroy the more valuable stuff first, and toss the remains out the airplane too. "
