That's a clever attack.

However modifying the entropy though via injection into the stream I think would be hit or miss.

The attacker would have to intercept and respond before the two devices do, or force a failure and renegotiate on entropy. This makes it a bit of a random chance.

So you would have to be there when someone of interest if pairing, and THEN be able to respond before the handshake on entropy completes.
