  • Just use mTLS via QUIC, it’s standardized, secure, future proof and has implementations in tons of languages and supports proper certificate checks and that whole ecosystem around it which they apparently tried to reinvent. It’s such a great protocol for these use cases, I don’t get why it’s not used more.

  • Glad to hear they are moving to iroh instead of a custom protocol. This is the problem with rolling your own stuff.

    As a bonus, this should help camouflage the traffic. (Iroh is becoming more common.)

  • > The network protocol used by Radicle does not give the confidentiality it was expected to give. Anyone who can observe the network path between two nodes can read the data they exchange as the data is sent in plain text.

    Is this a... design choice? This feels like too egregious of an omission to be a regular vulnerability here.

  • This whole project reads like amateur hour. Still using curl pipe to shell install and everything. Plus this lax security disclosure with just an outstandingly foolish security flaw. Gross.

  • Radicle has been one of those projects that had seemed interesting, but something always bothered me about it. (I think it was very highly tied to the cryptocurrency movement for a while? And the Cyphernet GitHub org seems to have rebranded from a DAO?)

    This, unfortunately, kinda seals the deal on never using this thing, at least not for anything I intend to keep private. This isn't about proficiency in some protocol which has XYZ footgun: they never checked that payloads were encrypted. Ridiculous.

  • The fact that this was reported three months ago and the "workaround" is to stop using private repos and assume they are all pwnd is quite something. How do you not notice that cross-node traffic is not encrypted when building something like this?

    announcement 3 months later is not super great, considering that the current advice is "Stop using private repositories (over the network) until the security update is released."

    > Network traffic between nodes is not encrypted and not authenticated.

    Oh.

    After all of the work they put into using cryptographic identities and decentralization tricks, how did they forget to do anything about the network traffic?

    Was this a case of thinking they'd handle it later, but then it fell off the TODO list?
