Klarna users are being signed in to random accounts

"The payment giant Klarna, which has 87 million customers globally, currently has major technical problems. Users of the company's app saw other customers' payments and personal information, before it was shut down completely.

The supervisory authority Finansinspektionen, FI, has asked Klarna to explain what happened."

A future, fascinating post-mortem I hope!

I find the default Twitter response by the Klarna social media account really annoying. The issue is not a system disturbance. The issue is clearly in the whole implementation of the system itself, code which was written by developers and where something really stupid has been implemented and where security was not taken into account at all because an issue like this could have been prevented at so many layers and yet it happened.

you have to wonder why they decided to stay up. Surely, if you have a leak this bad, you pull the plug until you can fix it.

Huh, from the headline I was thinking it was intentional! Nothing but marketing fluff in the newsfeed yet, still waiting on an article that's not walled in Swedish(?).

MS Exchange outlook web interface sometimes showed me completely unrelated mailbox content upon login: folders, list of messages, read status, subjects, etc. Trying to open email never worked though and the whole problem goes away after page refresh.
