Thanks to PSD2 most european banks have APIs, so there isn't actually any requireent to use the bank's apps anymore.
Tell me more? Are there opensource banking apps that work or can for example gnucash use these APIs?
That’s not a reality for any Belgian banks as far as I can tell.
One bank even shut their doors, took down their website, and forced all their customers to either use their non-free app or lose access to their money.
I don't know much about Belgian banks, but the first one I found is Ing, and here is their documentation: https://developer.ing.com/openbanking/home. I'm sure searching for " bankname PSD2" will give you results for other banks.
Looks like Ing still maintains the linux CLI app. I thought they discontinued that but it’s apparently still maintained. I’ve never seen a FOSS app from any other Belgian bank. FOSS phone apps are entirely non-existent for all Belgian banks AFAICT. The link you posted does not appear to lead to one.
BTW, wouldn’t it be strange if Ing had a FOSS Android app considering their app from playstore detects when it’s launched in a virtual machine and then refuses to run? If they had a FOSS app, the user could make it run inside a VM.
Be the change you want to see. The API is there. Go build that FOSS phone app.
I agree with that principle. And for me, that leads me elsewhere. (I’m not the OP)
I oppose forced banking. I also oppose forced online banking within the banking sector.
Forced online banking
Technologists are mostly incompetent, evidenced by today’s web which is increasingly enshitified. The ultimate escape from incompetently implemented shitty tech is an offline/analog option. It’s important for consumers to be able to say “fuck this, I’m done with electronic access.” Naturally you’d think if you write the app yourself that solves the problem. Not exactly. That API is still controlled by the bank. While the API is likely decent, there’s a firewall around it. Banks are increasingly making stupid anti-consumer moves in their firewalls:
These factors are outside of the control of the app developer. A developer could invest a lot of their own time building a great app, only to be demoralized by aggressive firewall anti-features. And worse, if the dev boycotts Cloudflare and/or the bank, their FOSS app continues to benefit the bank after they begin their boycott. IOW, the fruits of their labor is used against them.
Forced banking
Banks are becoming increasingly anti-consumer both online and offline. I could fill a book on this. But to be brief, imagine a bank decides to force everyone online, they close their countertop service, and then force people to obtain a mobile phone, mobile phone service, and force them to share their mobile phone number with the bank. (yes, this has actually happened). The ultimate escape is being able to function without a bank. The #WarOnCash is killing that option off so we are being forced to use banks.
So when you say “Be the change you want to see”, that’s exactly what I’m doing by living an unbanked life and fighting against the war on cash. In that mission, producing a FOSS app would actually be antithetical. A FOSS app would make banking a little more satisfying when it’s more important to have unbanked people fighting for the right to live an analog life.
Surely you are not suggesting that Cloudflare has access to end user credentials? Why would you say thay? Do uou have any hint of proof that that is the case? It would be a massive no-no, and heads would roll. If you hate electronic banking, here is your chance to take them down.
Cloudflare holds the keys. They decrypt all traffic that reaches their reverse proxy. It’s legal. Banks can outsource anything they want and they do so willy nilly. Their privacy policies cover this.. they can share whatever they need to with their partners.
BTW FWiW, I have caught banks breaking a few laws and reported it to regulators. Regulators don’t care. Everyone thinks consumer banks have a gun pointed at them to comply with the law because it periodically makes a big splash in the media when they’re caught not enforcing AML rules. But when it comes to consumer protection, anything goes to a large extent. There’s very little pressure to do right by consumers. One regulator even had the nerve to say to me “why don’t you change banks?” (in response to a report of unlawful conduct).
I'm well aware that Cloudflare holds the TLS keys. I'm also well aware that that does not equal having access to credentials.
Banks certainly can not outsource willy nilly. Or well, I suppose they may in some jurisdictions, but the context here is Europe, where the banks actually are regulated.
Can you elaborate? I believe the hashing must be done on the server side not the user side, so Cloudflare would see the creds before hashing. I know it’s possible to subscribe to an enterprise package where you hold your own SSL keys, but it’s unclear why CF would even be used in that scenario. If CF cannot see the traffic, it cannot optimize it as it all has to be passed through to the original host anyway. AFAICT, CF’s only usefulness in that scenario is privacy of the websites ownership - something that banks would not benefit from.
US banks (esp. credit unions) outsource with reckless disregard for just about everything. Europe is indeed different in this regard. But European banks have no hesitation to outsource email to Microsoft or Google and then to use email for unencrypted correspondence with customers. That crosses a line for me.
European banks will also outsource investments to JP Morgan (one of the most unethical banks in the world), and they tend to be quiet about it. I boycott JPM along with other similar banks in part due to investments in fossil fuels and private prisons. This means banking in Europe is a minefield if you boycott the upstream baddies.
Without TLS termination Cloudflare is still useful for e.g. DDoS protection, and serving content that do not contain client information.
Caching client data globally using Cloudflare would be pretty pointless and help very little and probably even be harmful to performance, so them having the TLS key for it would absolutely not be worth it.
I’m not seeing that. Cloudflare’s DDoS protection is all about having the bandwidth to serve the traffic. If CF cannot treat the traffic itself (due to inability to see the payloads), that whole firehose of traffic must be passed through to the original host which then must be able to handle that volume. CF’s firewall in itself is not sophisticated enough to significantly reduce the traffic that’s passed along. It crudely uses IP reputation which can easily be done by one’s own firewall. What am I missing?
Well, it seems people are prepared to pay quite a bit for cloudflare DDoS protection. Maybe you are right, and they are all wrong. But it does not really matter, because they cmearly have convinced people that it is worth paying for it, even if you disagree.
I’m not looking to be proven right. The purpose of the tangent discussion was to substantiate whether or not bank creds are exposed to CF. If banks are actually protecting consumer creds from CF, then it requires a bit of analysis because banks don’t even disclose the fact that they use Cloudflare. They make the switch to CF quietly and conceal it from customers (which is actually illegal - banks are supposed to disclose it but it’s not enforced in the US). AFAICT, CF’s role is mostly useless if the SSL keys are held by the site owner.
In the US, the financial system is quite sloppy with user creds and user data. There are even a couple 3rd-party services (Yodlee / Mint) that ask customers for their banking creds at all the places they bank. This service then signs on to all the banks on behalf of the customer to fetch their statements, so customers can get all their bank statements in one place. IIRC some banks even participate so that you login to a participating bank to reach Yodlee and get all your other bank statements. Yodlee and Mint are gratis services, so you have to wonder how they are profiting. The banks are not even wise enough to issue a separate set of read-only creds to their customers who use that Yodlee service. In any case, with that degree of cavalier recklessness, I don’t envision that a US bank would hesitate to use CF in a manner that gives the bank the performance advantage of CF handling the traffic directly. But I’m open to convincing arguments.
It seems like a lot of your points hinges on this being true, but it simply isn't. There is a massive benefit to preventing DDoS attacks, and that does not require keys. There is no indication that banks are handing over client ctedentials to CF.
“AFAICT” expands to “as far as I know”, which means the text that follows not an assertion. It’s an intuitive expectation that is open to be proved or disproved. The pins are all set up for you to simply knock down.
This is unexplained. I’ve explained how CF uses its own keys to offer DDoS protection (they directly treat the traffic because they can see the request). I’ve also explained why CFs other (payload-blind) techniques are not useful. You’ve simply asserted the contrary with no explanation. HOW does CF prevent DDoS in the absence of treatment of the traffic? Obviously it’s not merely CFs crude IP reputation config because any website can trivially configure their own firewall in the same way without CF. So I’m just waiting for you to support your own point.
This is trivially verifiable. E.g. if you get the SSL cert for eagleone.ns3web.org, what do you see? I see CF keys. That means they’re not using the premium option to use their own keys. Thus CF sees the payloads. I’m open to being disproven so feel free to elaborate on your claim.
How many websites can handle the amount of traffic that CF can handle? It's not just about configuring your firewall, it's about having the bandwidth. Otherwise it's not much of a DDoS protection.
As I don't have an account there I can't see which requests containing credentials use which cert.
And also, just because the cert is verified by cloudflare does not mean they have the private key.
That’s what I’ve been saying throughout this thread. The only significant DDoS protection offered by Cloudflare requires CF seeing the traffic (and holding the keys) so it can treat the high-volume traffic. If CF cannot see the payloads, it cannot process it other than to pass it all through to the original host (thus defeating the DDoS protection purpose).
Why would you need an account? Why wouldn’t bogus creds take the same path?
If it’s true that this is unverifiable, that’s good cause to avoid Cloudflared banks. It’s a bad idea for customers to rely on blind trust. Customers need to know who the creds are shared with /before/ they make use of them -- ideally even before they make the effort of opening an account.
This uncertainty is indeed good cause to avoid using a Cloudflared bank.
UPDATE: I’ve spoken to some others on this who assert that it is impossible for a bank customer to know for certain if a bank uses their own key to prevent disclosure to CF.
