German law is making security research a risky business.

Current news: A court found a developer guilty of “hacking.” His crime: he was tasked with looking into a software that produced way too many log messages. And he discovered that this software was making a MySQL connection to the vendor’s database server.

When he checked that MySQL connection, he realized that the database contained data belonging to not merely his client but all of the vendor’s customers. So he immediately informed the vendor – and while they fixed this vulnerability they also pressed charges.

There was apparently considerable discussion as to whether hardcoding database credentials in the application (visible as plain text, not even decompiling required) is sufficient protection to justify hacking charges. But the court ruling says: yes, there was a password, so there is a protection mechanism which was circumvented, and that’s hacking.

I very much hope that there will be a next instance ruling overturning this decision again. But it’s exactly as people feared: no matter how flawed the supposed “protection,” its mere existence turns security research into criminal hacking under the German law. This has a chilling effect on legitimate research, allowing companies to get away with inadequate security and in the end endangering users.

@WPalant that's like saying it's breaking & entering if I give you a key to my house. I gave you the key, ergo you had permission to be there.

husjon

@thisismissem @WPalant you could also twist it a bit more and say you left your key under your door mat, not even explicitly giving them the key.

ww
@husjon @thisismissem @WPalant if you really want a metaphor, here's a more accurate one. there's a fulfillment center, and each customer is issued a delivery robot that will drive there and retrieve their deliveries. one customer followed the robot to see where it goes and saw that the door opens for any robot and stays open long enough for another person to enter, allowing access to everyone's deliveries. reported that to the company and got sued.
cognitively accessible math

@husjon @thisismissem @WPalant Yes, that's the better analysis. "Attractive nuisance" idea works well, too. If you make it too easy/tempting then it's your responsibility.

Yellow Flag

@thisismissem Difficult. If we spin this analogy further: you gave me your key for a specific purpose (e.g. pizza delivery while you were out), after which I returned it to you. You didn’t allow me to make a copy of this key and use it later to rearrange the furniture for example.

Abusing hardcoded credentials can definitely constitute hacking and cause perfectly justified criminal charges. But intention and damage caused definitely need to go into the equation, not merely “circumvention of protection mechanisms.”

Emelia 👸🏻

@WPalant in this case it just sounds like he used the key to open the front door, saw an absolute mess & notified the company of the issue

Bartosz Rakowski

@thisismissem @WPalant this seems to omit the other side of the story. If I understand this correctly, vendor software was making undocumented calls to outside infrastructure and sharing potentially sensitive data. It should be in company's right to check the level of exposure to properly protect their and their customers' rights.

Thomas Tempelmann

@RakowskiBartosz @thisismissem @WPalant Well, no. You can't demand the right to look into the internals of your partners - they have a right to privacy as well. You are instead "protected" by the law that requires the partner to protect your privacy interests, or by contracts. What that law is missing, however, is a way to universally verify that they do it correctly, e.g. by independent auditors. Which isn't often feasible, though. It's all a compromise, and it sucks.

Riley S. Faelan

@RakowskiBartosz

Surely you forgot to add a sarcasm tag.

The vendor is almost certainly out of GDPR compliance.

@thisismissem @WPalant

Tamas K Lengyel

@WPalant @thisismissem Intent and damages should absolutely matter. But it's also common sense not to use the hardcoded credentials to login and dump the database. Or if you do, why report that you did? Perfectly sufficient to just say you found the hardcoded credentials and stop there.. Bad practice on both sides.

Yellow Flag

@tklengyel @thisismissem Where did you read that he dumped the database? My understanding is that he connected to the database in the assumption that it was specific to his client, then disconnected and reported the issue immediately after realizing that it contained data on other customers as well.

Tamas K Lengyel

@WPalant @thisismissem Just connecting to the db won't show you what data is in it to determine it's not just your data. So he must have dumped it or at the least queried it sufficiently deeply to make that call.

DELETED

@tklengyel @WPalant @thisismissem I hate this thread. Also responsible disclosure is a thing and should be protected under law. Vendors doing something stupid than pressing charges is incompetence and should be audited by a gov agency.

This thread and this case is why people don't bother reporting anything they find without malicious intent and just watch the company shoot themselves in the foot.

Tamas K Lengyel

@alex_02 @WPalant @thisismissem I agree, but the reality is that you are better off just ditching that vendor if they won't fix the issue. Then why not publish the issue anonymously? If you aren't going for a bug bounty what is there is to gain by attaching your name to it?

DELETED

@tklengyel @WPalant @thisismissem why does disclosing a security issue require to be a bug bounty or publishing it anonymously? Treating hackers and researchers like terrorists is just making things worse and why threats like ransomware gangs have such an easy walk in the park with breaking into networks.

Alex Rock

@WPalant @thisismissem

Many judges in court don't know jack shit about programming, and "compiling" is the same as "encrypting" for them.

As many analogies said: if you give someone the key to your house, whether it's wrapped in tons of cardboard and tape, they still have the key.

The software provider must be condemned as a security flaw, endangering all users.

Leonid 🇮🇱

@thisismissem @WPalant I understand this case more like you put your key in front of your house, visible for everybody. And I'm just telling you that it is a security issue and you are suing me for that.

Yellow Flag

@leonid @thisismissem Well, you did verify that it isn’t just any key but the one opening my door. It’s the fact that you opened the door which got you into court.

In fact, even that analogy doesn’t really convey the situation – it’s not actually the key to my house but rather to the storage facility where I keep stuff of people who paid me. And that key puts their stuff at risk.

Leonid 🇮🇱

@WPalant @thisismissem now I get it. The issue was that he accessed vendor's database. Even if he has the credentials, he is not allowed to use it.

It's like if I found a post-it with password on your PC, I'm still not allowed to use it to login into your account.

crazyeddie

@thisismissem @WPalant More like you put a lock on your door that has no tumbers because you didn't know this because it's a "secret"--and someone comes along and says, "Hey, those locks have no tumblers and can just be turned with a flathead," and that person is arrested and imprisoned. No actual entry is required and its been this way for almost 3 decades. Can also be used to imprison someone for the act of selling you a screwdriver or just telling you how to forge one.

JR Freeman

@thisismissem @WPalant It's more like someone found a key hidden in a very obvious place.

Like, if you call the plumber because of a leak in your yard, he can't find it, so he let's himself in with a key under the mat and finds the problem in your house. He was doing the job you hired him to do, but you might be a little uncomfortable learning he's taken liberties with your locks in order to do so.

Now, whether that discomfort means a crime has occurred is another matter.

@weddige @cifvts I’ve learned to keep my expectations low with this government.

@WPalant @cifvts I'm certainly not without some unease, knowing that this bill will be drafted by the Ministry of Justice (with, I'm sure, terrible input from the Ministry of the Interior).

@Doomed_Daniel @WPalant @darren Schöffen are not assigned based on their competence in the case, but through a randomized system. E.g. in Berlin you get a list of appointments for the next year, and whatever case takes place on that date is the one you judge on.

jesterchen42

@WPalant And we've had this discussion ad nauseam in the past: if you circumvent any protection mechanism, no matter how stupid, it's bad for you. So deCSS is basically illegal in Germany, even though this wouldn't count as any security "best" practice.

Also, programs that can be used to take part in computer crimes, may not be produced, distributed, downloaded or possessed in Germany - if it's the only purpose of that tool. So either forbid notepad or add a funny feature to such tools. 🙄

jesterchen42

@WPalant And yeah, basically downloading Kali might get you to jail.

Yet another law that was created despite the protest of several groups like digitalcourage or CCC. Luckily, they're probably addressing it.

Sadly, they're probably addressing it. I fear the outcome - as long as our knowledge of "internet" is that one shown in the article above.

And always remember: pushing F12 is a crime as well. ^^

Anthropy :verified_dragon:

@WPalant I think we should actually ban judges and lawyers that don't know how computers and software works, from making judgements about these areas. This is absolutely ridiculous, it's like accusing a customer that walked into a store full of illegal wares and gently told the store owner that this might not be a good idea, that they were stealing these wares and breaking into the store. it literally couldn't be more backwards

Patrick $8 :verified:

@WPalant A protection mechanism isn't circumvented when used as intended. The vendor supplied credentials to their customers with the specific intent for them to be used. German judges are morons

Alexander Goeres

@WPalant I imagine this will lead to all the German security researchers moving to another country in Europe if it stays.

@hamato No, there is a high court decision clarifying that dual use tools are exempt from that rule.

hamato

@WPalant Yeah okay, that's *not* really better, because it mostly covers "professional use". While I am an IT consultant, I am *not* a security consultant so professional use probably'd never apply.

The part about malicious intent is also something I'd decidedly not like to test in court, because it's way too easy to assume and way too hard to disprove.

But it's great to see Karlsruhe involved in this. Once or twice more and we might even get reasonable hacking laws. 🙈

Edin 🇪🇺

@WPalant I mean the learning for the guy who discovered this vulnerability is that he should not have revealed it.

@techtraveler @WPalant Or he should have pseudonymously leaked it them using a throwaway account. With a note to the effect that if they didn't correct it, the next step would be to post it to a public forum.

Varbin :arctic_fox: ​:gay_furr:

@WPalant From the article I read that the judge is actually on the side on the defendant, but does have no other option - the law currently states this.
Possibly the judge hoped that a higher court can make a precedence. This would not be the first case where the judge and the defendant agreed on a (very) mild sentence to allow a revision/appeal to create ruling by a higher court.

Felix "tmbinc" Domke

@WPalant "Auch wir fanden bei einer Untersuchung entsprechender, frei im Internet zugänglicher Binärdateien der Firma Modern Solution, Passwörter im Klartext."

@PiiiepsBrummm @pluralistic Sorry, I’m not really convinced. It is a problematic law, as it rules any data access to be illegal as long as the data is protected – it does not set any requirements on that protection. It doesn’t even require the data to be remote: I could access data on my own computer protected by military-grade ROT13 encryption, and it could be considered a violation of this law. This extremely broad definition is why we now have courts carving out restrictions where this law violates common sense, and they won’t always produce sensible results.

Every law needs interpretation. You _can't_ include all definitions and possible exceptions. If you would do this, the code for a bike fit for road use would still involve a 6V dynamo. Battery lamps not allowed.

The whole ruling depends on the interpretation of "protected". The error here is believing, that a hardcoded and unencryprted password fulfills the definition.

@SiteRelEnby Hey, I totally agree that Germany did really badly in this area, but are you certain about that “ripped out” and “replaced” part? From all I know, Germany merely stopped paying for building up clean energy capacities which essentially killed this industry branch. But whatever was there already stayed there (healthy increases again under the new government). And Germany isn’t actually expanding the capacity of its coal-fired power stations, though it could certainly retire them sooner.

@WPalant If I understand right, the developer found hard coded credentials being used to connect from his instance to the vendor. I think at that point, he has no reason to believe that using those credentials will give him access to anything other than his own data. As soon as he saw otherwise, he backed out and did responsible disclosure. Two thoughts:

1. This will have chilling effects on responsible disclosure (perhaps the goal).
2. If you give me the credentials needed to access a dataset, I don't think you should be able to claim the existence of those credentials as an access control meant to keep me out.
