They can very easily decrypt iMessage traffic using the method outlined in the article. They simply provide the sender with an erroneous key.

Not according to GGP's definition, which didn't require merely that messages stay encrypted between endpoints but that middlemen have no way of decrypting the data.
- saagarjha 7y agoMiddlemen don't have a way of decrypting the data, because they don't have the keys to decrypt it. If they're malicious they can try to send you new keys to use, and only if you accept them will they then have the keys to decrypt your messages.

Apple's own "Apple Platform Security Spring 2020" document does not claim any such thing. It says the device requests keys from IDS at the start of a conversation and just uses them. The article I linked to above said that Apple fixed several other bugs the researchers pointed out but not that one, which other researchers had also described to Apple years before.
