#133Their German counterpart, Sofortüberweisung, didn't properly blacklist test credentials given out by banks e.g. to developers in the beginning, so people could simply use those and pay for goods and services with fake accounts. For me there are so many red flags with all these services, as they basically "steal" your credentials to log into your online banking. And while they claim that they only use the credentials…
Can you explain more about the credentials and online banking? I've used (and integrated with) Klarna in the UK and from what I've seen it's only really a payment method with merchants who you pay back by card later.
They provide "pay by bank account" (which involves the mentioned MITMing of users' online banking accounts, unless Klarna is integrated with your bank via OAuth/PSD2, which is still not ubiquitous), but also installment payments/factoring and others.

There have been some weird legal cases in Sweden where businesses and scammers have been freed after having signed in using other people's "BankID" to change retirement savings around or send cash. Its the ID method I use for credits, pharmacies, health care, taxes, but was apparently not an ID so it's not id-hijacking. Klarna has man in the middled my bank account before and performed a purchase and I've boycotting…
As far as I know most, if not all, of these scams have been perpetrated against the elderly. All operations (authentication, signing) can be initiated remotely with just a personal ID number, so the typical scam meant calling up someone and claiming that "an authentication must be performed", and simultanously initiating a bank login session. If you can keep the victim on the phone and using the BankID app when you tell them, you could basically login and empty their bank accounts. This has been largely fixed using QR codes to initiate login requests for major internet banks (which means you have to be in front of the same screen now) and other clever workarounds. But it has also always been a fact that there will be a description saying what you are signing, in the app, so being careful you could easily avoid being scammed.
I think its largely a great asset (BankID) but its never gonna be 100% tamper-proof without being seriously neutered.

Klarna is actually its own bank these days so that doesn't really happen anymore. I think however many other payment providers operate this way still which is ridiculous. Then again, PSD2 API roll-out has been very ???

Re: Klarna users are being signed in to random accounts
#139Will be interesting to see what the problem is here. From what I have seen in real life my top guesses are. Some dependency on static variables in code. Reversed proxy with incorrect cache rules that ignores headers or some parameter.
How do you envision the static variables thing? I've seen the cache thing myself in real life but not the other.

#140Sometime in the future, people will stop belittling crypto currencies when they realize that the digitization concepts of traditional finance technology providers are inferior to those of crypto currencies and blockchains. Putting safety and security first for anything that handles money makes sense. The calls for "you don't need a blockchain, just use a database" will become less and less. Edit: Of course, Hacker Ne…
Its not like BitCoin and other Coins are free of scams/fraud because they are not regulated...
Most blockchains startups need to create problems which nobody has to sell it to people who don't know better...
