Why would these public network would allow guest hosts to communicate with each other?

I think they're saying you create your own malicious wifi network and people will unintentionally connect to it. This network specifies your malicious DNS server via DHCP, and everything looks secure to the client. I think the main issue with this in practice is that all the major browsers have been updated to not trust these certs.

So you target some host like ssh.dev.azure.com, find all the hooks in the proper repo the client is trying to access, make a new commit that puts your persistence payload in one of them that you expect will be executed soon, this script can additionally "correct" the git state when it finally runs, and moves its persistence to some more appropriate location.

Users will be none-the-wiser because they're not accessing these hosts through a web browser, and you net a few more compromised hosts in your inventory.

Yeah also got to be lucky that the users are using https and not ssh. You're very limited in what you can mitm, you'll be trivially detected by patched devices (though maybe not acted on because nobody is the wiser), but then you'll need to serve objects with common/conflicting hashes -- fixing up that state synchronisation (what you call "correct") to then do nefarious things is not trivial at all. Extremely difficult to pull off successfully for git anyways or to do it in stealth.

Ahhh, true, SSH isn't the same certs, my bad... well, both Github and Azure DevOps default to HTTPS-based cloning anyway...

They wouldn't. A device like the Pineapple broadcasts its own copycat wireless signal and tricks unsuspecting clients to connect to it thinking it's the real one.

It's good to see push back against this narrative that is trying to develop that this isn't any kind of big deal.

This has been every machine on the internet compromised for at least 12 hours and probably some that are not going to ever get patched.

This is a HUGE deal for embedded devices, we can now mitm HTTPS traffic on lots of embedded devices running Linux produced between 2018 and now.

They don't need to, a Pineapple (or anything else that can run a wireless access point, you could do this with a laptop) just needs to advertise the expected SSID and do so with a stronger signal than the official ones for people's devices to connect to it instead of the actual network.

It’s extremely common to see other Macs pop up in the ‘network’ panel in Finder in the independent coffee shops around me. I imagine they’re just signing up for a business plan and using the routers the ISP gives them with a custom SSID and password.

You dont interact with anyone. You just set your own hotspot and people will connect to it.
