Impossible! I suppose that's the whole point of his blog.
I highly doubt that the side-channel he mentions is exploitable in real-world conditions on a server with dozens of users where each request might be handled by a different processor core — and that's exactly what Matrix dev told him.

He can always prove us wrong by making a proof of concept exploit, but no… "I did look into this, but I didn't spend too much time on it… but this is a HORRIBLE vulnerability, a GAPING HOLE even — just use Signal" 🤦
