jgreco writes "A judge in North Dakota has just ruled that requesting a zone transfer from a public DNS server is criminal activity within the meaning of the North Dakota Computer Crimes Law. A zone transfer is a simple request that a DNS server hand over information in bulk, and a DNS server may be configured to allow or deny such requests. That the owner of a DNS server would configure the server to allow such requests, and then claim such requests were unauthorized, is simply stunning."

"In all intended uses of a zone transfer, the secondary server is operated by the same party that operates the primary server. A secondary intended purpose for zone transfers is to permit trouble shooting in which case zone transfers may sometimes be undertaken via the manually conducted host -l command. In those instances, however, the person conducting the diagnosis acts with the authorization of the operator of the system and is usually the network administrator for the system."
Sounds like the judge understood it pretty well to me.

In this case, the geek in question performed the DNS queries as part of an ongoing investigation into the spam activities of the ISP in question. This was not a case of someone with malicious intent, or even someone exploring for the sake of exploring, this was a computer professional attempting to track the source of some spam and to compile evidence against the spammer. In this regard he was acting more as a PI (I realize a PI is usually licensed by the state, but it's still close enough) in attempting to investigate something that if not directly a crime, is at least questionable.
If I was investigating you, and I came and knocked on your door saying "My car broke down, can I use your phone to call a tow truck?" and while inside your house used a hidden camera to take pictures, this would also be "not authorized", but in most states it's still perfectly legal, and you couldn't then turn around and try to sue me for trespassing.
The reason the judge ruled against the defendant in this case seems to have had a lot less to do with the merit of the case then it did several instances of the defendant giving false testimony, and in at least one case directly violating an order of the court. Essentially the judge was ticked at the guy, and that biased the case against him.

Well, there's a problem right there. No one person knows all the intended uses of a zone transfer. I learned a new one today from a sibling post -- actually migrating DNS information to a new host, when switching service providers.
*chokes on breakfast* ...what?
I've been using it for almost a year now, for dynamic DNS. It means I get to configure and run a real DNS server, and set it up exactly the way I like, and then, when I need to update the records on my real DNS servers (at zoneedit.com, dyndns.com, etc), I only have to change one setting -- the master host. This means that, for example, if I want to switch to another system, I don't have to learn a new API (or write one to crawl their website) that's much more complicated than a single POST request, updating which master server they should update from.
(Just been reading that zoneedit.com sucks, so I'm considering switching to dyndns.com, which honestly is pretty cheap, and their service which does zone transfers is cheaper than their service which has a web interface.)
That is to say: I operate the primary server, and the secondary and tertiary servers are operated by a third party, even if these secondary and tertiary servers are listed in my domain as primary and secondary servers. This is hardly unique to dynamic DNS -- it's also used in cases where there is a static IP, but you only want to maintain one server, and you (obviously) can't guarantee five nines of uptime on that server. So you pay someone to run a secondary DNS server.
That's reasonable, but answer this: If I were to use the "host" command -- just "host", by itself, looking up MX records and such -- should I be worried about it being illegal? What about "whois" and such? There are plenty of times when it's reasonable to expect that a third party should run diagnostics -- such as when the first party is completely clueless, and needs to be told so. [centos.org]
Some other poster put it very clearly -- geeks generally believe that if you make a service public, it is public. It's certainly possible to limit zone transfers to the IP address of the secondary DNS server. This would not be an absolute protection, but it would at least show what the intent was.
This has been debated fairly often with respect to open wireless access points. What you have here is, according to the machine protocols involved, a machine shouting "Look at me! My name is LINKSYS, and I'm open! Just connect if you want to get online!" It is trivially easy, in most cases, to have it instead broadcast "My name is LINKSYS, and you'll need a password to connect!" Or, alternatively, to not brodcast at all -- to just sit in a corner until someone says, "Hey, LINKSYS! Let me connect!"
It's not quite that bad, but it's similar. "Hey, ns1.example.com! Would you mind telling me what all the subdomains of example.com are?" (There are legitimate reasons for doing this, too -- maybe I'm a spider, and I want to find web pages which aren't specifically linked to by www.example.com.) At this point, if ns1.example.com says "Sure! There's mail.example.com, and www.example.com, and, oh yeah, super.secret.stuff.example.com"... how is this your fault? If super.secret.stuff was really that secret, ns1.example.com could've left it out, or could've said "No, sorry, I'm not going to tell you."

The act of putting up a website (or any other internet server) on the public internet should be enough to say the operator of the server gave you permission to access it. If you don't want people accessing your server, at least put a password on it for basic access control, or if it requires more security, than put it behind a VPN/Firewall box.
The act of putting up a DNS server is exactly the same. But we now know it's illegal to access a DNS server, therefore it must be illegal to access a web server.

If a service is running on a machine connected to the Internet and that service is obviously not secured, then the only thing that can be assumed is that permission to use that service is implicitly granted, especially in absence of notices stating otherwise.
IOW, if you run a Web server on port 80 and require no authentication, then it can be easily assumed that you intend to publish any materials served via the Web server to the public Internet -- you expect people to access it.
Ditto if you run a DNS service that allows zone transfers to all comers -- you expect that DNS zone transfer will occur and no one will need permission from you to do so.
To rule otherwise is nothing but pure stupidity.

If you had, you would probably at least know that the Judge was a 'she' not a 'he'. If you did actually read the article, this might be a good indicator of how much you actually paid attention to what you were reading...
Several of the 'conclusions of law', as stipulated, are indeed seriously problematic. She did not specify her rulings upon the basis of an injunction. She specified them based upon the actions themselves. THAT is why technically savvy individuals consider her ruling to be badly flawed.
Her conclusions on Zone Transfer Queries, for starters, are seriously flawed. There are plenty of legitimate reasons to make DNS Zone queries when you are not an employee or someone else acting with the explicit permission of the entity who put the server in place. Many ISPs cache entire zones to cut down on excess DNS traffic for requests from their customers, for example.
For another, while it is difficult to say with certainty not knowing the exact details of the testimony of the defense's expert witness, a reading of her response by someone knowledgeable with DNS configuration suggests reasonably that he may have attempted to explain that there are specific methods that would be used to prevent zone transfers to unauthorized servers, that there were other methods that would be used to configure the server to provide zone information in response to external requests, and that by configuring their DNS server in such a way as to give the Zone information, the plaintiffs were authorizing the transfer of information and making the information publicly available. If their DNS server was configured to respond to external Zone Transfer requests, this information would in effect be public, as anyone at all, not just the defendant, who issued a perfectly normal host command would have received that information. If this was not their intent, the issue would be one of incompetence on the part of their technical staff, not one of 'hacking' on the part of the defendant.
Her suggestion that using a command switch for 'host' that is clearly documented to query information that was publicly available constitutes 'unauthorized use of a computer system' is unfounded, overly broad, and, to any technically knowledgeable individual, deplorable. She does not state that she reached her conclusion because of any injunction against the defendant. She states her finding is based upon the facility of the program itself, and her miraculous idea that somehow use of this normal function is somehow mystically, only intended for a specific subset of target users she has imagined. One that is, again, seriously flawed.
'Knowledge available to the average user' should NEVER be used as a yard stick for what constitutes the acceptable bounds of computer use. The 'average user' is ignorant of the actual function and capabilities of their systems to a point that is common to describe them, quite accurately, as largely 'computer illiterate'.
If no one knew more about any particular thing than an 'average' individual does, at any given point in time, we'd still be hunting and gathering. To suggest that this baseline should have anything to do with determination of what constitutes a potential criminal act, if applied to any other circumstance, would immediately render anyone of actual knowledge, rather than vague theories about a subject a criminal.
What do you know, for example, about repairing the engine of your car. Say you know quite a bit about it. Should you be considered a criminal if you make repairs on it, based upon knowledge you have, if you aren't a certified mechanic? How about if you repair your mother's car with that knowledge. Does that make you a criminal? By this Judge's logic, it would.
If you don't like that analogy, try this one. Let's say that the 'average person' knows that telephone bo

This is bad because there was a cryptographer in the 90s that discovered that its possible to determine random number generation sequences based on your processor model and frequency. So it wouldn't be good for that info to be public.

In this case (ignoring the fact that the defendant already had an injunction against him) the operators could probably have prevented their DNS server to serve this data (probably, as I am not an admin in this area). In other cases, such as deep linking, well, it is a little rougher, but they could for example not use frames, but good page layout, which automatically shows all their ads in the standard headers and such, or make stuff password protected, or use .htaccess to redirect requests that go straight for their meat back to the frontpage, just like many free image hosters do now for hotlinking.

What you're forgetting is that in most court cases, the defendant is there for one of two possible reasons: they really weren't responsible, or they were responsible but are now lying about it. And the plaintiff or complainant is there to make sure something "legal" happens in their favor, and they're not above lying to get their desired outcome, either. Usually there's a lot of both. That means the judges are professionally sitting at the mouth of a never ending river of bullshit, and they have to keep control of the situation.
It's not that judges can't or refuse to understand the technology; it's that the cases are about the people, which is where their focus must remain. The computer didn't act of its own accord. It operated under the direction of its owner. The question of "was there malicious intent?" has nothing to do with DNS or any other logic-based technology and everything to do with the two guys standing in the courtroom.
