Hacker Jeff Moss Sworn Into Homeland Security Advisory Council

Wolfgang Kandek writes "Hacker Jeff Moss, founder of computer security conferences DEFCON and Black Hat, has been sworn in as one of the new members of the Homeland Security Advisory Council (HSAC) of the DHS. Moss, who goes by the handle 'the Dark Tangent' says he was surprised to be asked to join the council and that he was nominated to bring an 'outside perspective' to its meetings. He said, 'I know there is a new-found emphasis on cybersecurity, and they're looking to diversify the members and to have alternative viewpoints. I think they needed a skeptical outsider's view because that has been missing.'"

But to stay inside and really use your voice means either being threatened with being fired (at best), or saying things that you are allowed to, meaning, what was approved, not the full unabridged truth.

Perhaps he'll find out something about how the security/surveillance works, or something or other, not agree with it, and wish to denounce it. The choices will be laid out.

      a = x % 731
      b = x % 129
      Now take a number: say, x = 10,000. Easy to compute: a = 497. b = 67. Very easy to calculate. But, working backwards from a and b alone, can you determine x? Suppose a = 616 and b = 100; can you tell me what my number is? It's not quite that easy! You'll need to do a lot more math. Not too much, in this case, as this is a ridiculously simple code and the numbers are small, but a lot more than a simple integer-division-and-remainder operation.

      That's not an encrypted message. (Public-key cryptography is related but different.) That's a simple one-way cryptographic hash: a secret number (your password) goes in, and a mysterious hash-value (a and b) comes out, and there's no easy way to map it back. But if you give me the password, it's easy to check that it's right. That hash value is what's in your shadow password file. Except it uses MD5 or SHA or whatever-the-latest-hotness-is.

      Now, granted, there's few enough passwords that you can check them all, given enough time. (You might even precompute them all, which is why you add a little random 'salt' to each password that makes them all different. In the example above, the 'salt' could be 'add 12345 to X before hashing it'. You can store the salt next to the encrypted password - you'll need it to check the password. It only protects you from the guy who calculated all the passwords adding +12344 each time - his "rainbow table" of passwords and hashes is now useless.). That's why the shadow-password file isn't usually broadcasted to the world. You try to keep it reasonably secret: not world-readable, certainly not exposed to the Internet.

People can't reverse the process of decrypting your password because your password isn't stored there to begin with.

      If you want to know what is actually stored, follow the previous advice about looking up hashing algorithms. Quick a dirty answer: when you first type in your password, a hashing algorithm is run over it and a hash code is produced, which is stored. When it prompts anyone for your password, it doesn't know the correct answer, but whatever answer anyone gives, it runs through the same hashing algorithm and sees if it produces the same result. The odds of two different strings producing the same hash result vary with the algorithm but it can be something like 1 in 2^160.

      But the short answer is, your password cannot be decrypted because it wasn't encrypted and stored to begin with. There's nothing to decrypt.

      The password is not encrypted, it is cryptographically hashed (encrpytion is two-way, hashing is one-way). A hash function transforms an arbitrary length input into a fixed length output, so there is no inverse function in the mathematical sense: a single hash value has an infinite number of inputs corresponding to it. Finding a value that produces a given hash is extremely hard: a good hash function will not have any way of computing such a value more effective than brute force (e.g. you try all possible inputs until one of them given you the hash you're looking for).

      As for reversing the algorithm: in essence, the generation of the password hash always uses a stateful generator, and this state is not preserved in the hash. When trying to reverse the hash, you must know not only the hash but also the state of the generator at the end of the algorithm, otherwise backtracking to the initial state of the generator defined in the hash function definition can take more than the age of the universe, even if you used all the computing power on earth to break this single password. Another mathematical idea that is frequently used is that if you have two very large prime numbers x and y, you can quickly compute their product z, but you can't easily find x and y if you only have z. Unless you have a quantum computer, which doesn't exist yet.

      While I *love* the first respondent's answer, and giggled like an idiot when I read it, perhaps this will be more a more useful example for understanding how it works.

      The modulus operator in arithmetic returns the remainder after integer division. It is commonly noted "x % y", "x mod y", "mod( x, y )", or similar.

      So:
      3 mod 2 = 1
      4 mod 3 = 1
      4 mod 2 = 0
      5 mod 2 = 1
      5 mod 3 = 2
      5 mod 4 = 1 ...

      Now, suppose a password structure "x:y" -- you are required to enter your password as two digits, separated by a colon (not normal, but just suppose).

      You could enter, as your password, "4:3", and the system could store as your password hash "1" -- the result of "4 mod 3". Then, when you attempt to log in next time, if you submit "4:3", the system would take the modulus and check the result, "1", against its internal table of password hashes and allow you in.

      Now, suppose you get the table of hashes, and see:
      joeSmith: 1

      joeSmith has the password hash "1". Is his actual password "3:2", "4:3", "5:2", or "5:4"? Since the modulus of all those pairs is "1", the correct answer cannot be determined from the output alone. Modulus is what is called a "non-reversible function." The output of the modulus function contains less information than the input, so it cannot be reversed.

      In this example it is trivial, however, to generate another password combination that results in the same hash. For example, "6:5" also equates to the hash "1". This is called a collision between "6:5" and "4:3". The attacker does not have to know joeSmith's actual password, as long as he can supply input that results in the correct hash. That leads to the next step in identity verification systems: ensuring that it is not possible for a reasonably funded attacker to forge a document which collides with the actual document (or password in this case, which is a special kind of document).

      Using very rough numbers, at around 500 digits, around 99.9% of integers are composite, meaning around 0.1% are prime. (I'll leave proof of this as an exercise to the reader.) For the sake of the discussion, lets assume that is an accurate 'prime density' for the range of 500 digit numbers.

      So, to create a database of the 500 digit prime numbers we'll need to store 0.1% of them. So far so good.

Lets look at 3 digit numbers (100-999) inclusive; which equals 999-100+1 or equivalently 10^3-10^2.Or we can express it even more conveniently as (10*(10^2))-(1*(10^2) = 9*(10^2). And the general formula for how many n digit integers there are is 9*(10^(n-1)). For 500 digit numbers there are 9*(10^499).

      Ah, but we only need 0.1% because we are only storing primes, so we multiply by 0.001 or 10^-3 and get:
      9*(10^496).

      Our database is going to need around 9*(10^496) records for this...

      If it hasn't already made itself clear to you, this poses a serious problem. There are estimated to be around 10^50 atoms on earth. So even if you could store an entire database record on an atom, and the entire planet was used in our storage system, we'd still run out of atoms before we made a measurable dent in the data set we need to store.

      In fact, if we used every atom in the universe we'd still run out of atoms before we made a dent in the data set. The universe is estimated to have fewer than 10^81 atoms.

      The name of the House Committee escapes me, but they do yearly reports on computer security and gov't agencies regularly get Ds (up from their previous Fs).

      The big question is what do these grades really mean? Do they really provide any true indication as to how effective the Government is at securing their systems? Is a 'D' all that much better than a 'F'? And what does it mean if an organization manages a 'B' (mine did)?

      But at the same time, I get a feeling that it sort of does give an impression as to where things are. A 'D' just isn't all that great. But it is better than a 'F'.

      My little nook of the Fed world improved over the years. Infosec took on new meaning when the top of the Fed hierarchy started throwing around requirements and putting on their serious face. I would imagine things ARE getting better all in all. It's just darned hard to tell how much better.

      http://csrc.nist.gov/groups/SMA/fisma/index.html demonstrate its compliance with the security requirements as opposed to how well the requirements are actually implemented.

      NIST Special Publication 800-53 is what I had in mind. It's generated a ton of work for contractors to bring in auditors. And in my (limited) experience, it's a great opportunity for someone with no infosec background to "get in to security" as auditors are simply required to follow the documentation. Said documentation can be turned on it's ear by a sufficiently adept beurocrat in some cases (and avoided if your auditor isn't too technical in others). But despite my cynicism... it's something. There ARE some good practices in that document. And NIST has put out some nice automated scripts to help hash it all out (best keep an eye on what its doing though). So it's not ALL bad. Just not great.
