Sunbird just relayed messages back and forth using a Mac mini in a warehouse. They probably had something that read the messages app on there and sent to their app on the phone through their servers, and seemingly forgot to encrypt anything during this process.
This is actually sending messages as iMessage. It’s been reverse engineered which is an incredible feat, iMessage has been out like …10+ years? And no one figured it out yet until this 16yr old rocks up.
Doesn't iMessage require some sort of Apple-issued device id? A key, unique to a device, hard-coded in the SoC? (which is easy to block if over-used).
Which is why hackintoshes used to require crazy workarounds to get this working, even with Apple's own software, if I remember correctly (never tried myself, could be wrong).
It does, the article actually mentions that. Yes, they did get around or reverse-engineer it. The article does not describe how, though I imagine it's doing the same sort of workaround that Hackintoshes have to do. Honestly, it's quite a feat.
