Capture of USB Dongle traffic?

Are there any softwares or tools that will allow you to capture the
traffic information that comes from and to a USB Dongle (software
license control)?

Care to explain exactly why you wish to do this? Please speak clearly
and look directly into the camera....

Or tools : Yes, a logic analyzer does that for you.
Not on the message level though. On the bit level.

Good luck.

Google on: USB analyzer.

I'm sure Win Hill would be glad to help you on this project.

But seriously, most of this stuff has encryption algorithms complex
enough that no simple traffic analysis is going to help; the
datastreams are never the same.

That's true- however I would imagine that one attack scheme would be
to observe the traffic to the dongle in order to identify places to
patch the executable-- but I'm certainly no expert in the field.

Of course, that's assuming the OP has some nefarious intent-- perhaps
s/he has a legitimate need to debug the transactions between a program
s/he's written and a security dongle s/he's trying to incorporate.

If it wasn't nefarious, s/he would know that dongles that you buy, to
incorporate into your own software creations, come with all the
necessary software to do the handshake... my oldest son uses Rainbow
Sentinel stuff.

With a black box, encrypted random handshaking etc I suppose it could be
possible to determine the algorithm by observing the traffic for a long
time. Probably a VERY long time, distributed-processing levels of power
required. Depending on how complex the encryption is, I'd guess that it
might be easier to etch the lid off the chip in the dongle and extract
the encryption code for disassembly, or duplicate the dongles. As
another mentioned, cracks are usually done via software patches
anyway...the code is already there for disassembly.

I still just can't get over the fact that "dongle" is a real word.

Or a legitimate need to run somebody else's software without the dongle.

And what "legitimate need" might that be?

Sort of like a legitimate need to use the bank's money without an
account.

John, will you kindly cut out the behind-my-back at-my-expense
CRAP, supposed right-wing fun-making, or not? I've paid enough
in honest Dongle fees *, without any attempts to cheat, to earn
respect on that account.

* Over $150k.

OK, no sense of humor. OK.

But "right-wing"? How?

I might point out that you've said all sorts of disparaging stuff
about me, some demonstrably untrue [1], and none has ever got me
angry.

[1] Like calling me a Republican (no!) and a conservative (well,
that's a lot fuzzier, but I'm awfully liberal in the classic sense.)

Running very expensive software on a much more expensive, but
hardware-incompatible computer.

Or running it somewhere like a classroom where people keep stealing the
dongles.

Or running it in more than one location without having to get someone
to FedEx you the dongle because you left in a hurry.

Or general distaste for an industry that has managed to convince
lawmakers (and quite a few of their customers too) that fair use
doesn't exist; i.e., that we can't be trusted with the choice of
whether to obey the laws.

I for one am thankful that there will always be iconoclastic European
college students who can crack copy protection efforts just as quickly
as they're developed. There should be an endowment for these kids.

Surely you can do better:

Vendor gone bust and dongle enforces lame-o-matic 1 year expiry date and/or
one needs to reload $OLD_PROJECT (which is now hidden away in secret
proprietary format to "protect the CAD vendors IPR while screwing the
customers (tm)".

I'm sorry and I apologize for my ignorance. Are you a
Libertarian, then? I assume you're not a Democrat. Or
are you an Independent (which doesn't say much), like me?
