It’s too early to tell if what’s happened in Spain & Portugal was caused by a cyber attack or some sort of physical activity.
There’s a history of jumping to the former conclusion before the latter is proved true.

This is inaccurate. There is no known vulnerability with Signal's core tech. The memo was discussing phishing attempts, which Signal has worked to mitigate. And it was hastily reported.
It's important not to spread misinfo that can confuse people into moving away from meaningfully private comms.
