"If you don't live under a rock, you might've heard of Bluesky, a decentralised social microblogging app built on top of the AT Protocol. In early June 2023, I identified a vulnerability in Bluesky's core user identity mechanism, did:plc, which allowed me to modify the identity information associated with any* account. I tested my hypothesis by changing the handle of the official @bsky.app account."

Detailed breakdown of how bluesky/atproto (and to a lesser extent activitypub) work
"...Under these definitions, Bluesky and ATProto are not meaningfully decentralized, and are not federated either. However, this is not to say that Bluesky is not achieving something useful; while Bluesky is not building what is presently a decentralized Twitter, it is building an excellent replacement for Twitter, and Bluesky's main deliverable goal is something else instead: a Twitter replacement, with the possibility of "credible exit"."

"In this post you will learn about how I built a comment interface on top the ATProto protocol and Bluesky social network. The post is relatively technical, but I also try to tell a story of how I got to this point. Read on if you are interested in social networks, decentralized protocols, open standards, and Bluesky."
