I have no idea what this means. Can someone explain?
I mean I think you could also do this on Mastodon but it would just show a "verified" highlight for amazon s3 in your profile, not that it would get verified as your username.
This is why mastodon , webfinger and ACME uss .well-known uri prefix. .well-known is reserved and you can't e.g. make a bucket named .well-known It's funny the bluesky devs say they implemented "something like webfinger" but left out the only important part of webfinger that protects against these attacks in the first place. Weird oversight and something something don't come up with your own standards
Maybe I'm old but what are some popular use cases for webfinger? (I'm just learning about it now)
Seems like the crypto crowd is moving on to creating flaky decentralized twitter clones now
For those not getting the context(like me), this seems to be about the Bluesky Social( https://bsky.app/ ), a twitter alternative.
The official method is to set a TXT record, but apparently their "AT protocol" also lets you confirm a domain by serving `GET your.domainname.com/xrpc/com.atproto.identity.resolveHandle`
and `xrpc` was available as an S3 bucket name :)

If you can upload a custom file to a domain/subdomain, bluesky social (Jack Dorsey's new twitter) uses it to verify you are the owner of the domain. Chaz uploaded his custom file to their Amazon s3 bucket and now since he was the first one to do it, his account is now associated with Amazon S3.
Solution is also on the works like use /.well-known/, so this is more like funny, rather than a big problem. Key to trick was to have bucket named "xrpc" and store a file there: https://s3.amazonaws.com/xrpc/com.atproto.identity.resolveHa... There is also another funny thing in the image, the user posting about is sending one from "retr0-id.translate.goog", which is odd. Somehow he has got https://retr0-id.translate.…

It's ridiculous that this is not in the title.
