The devastating hacks confirm the analysis that I'm sharing in this post: that TeleMessage's server – hosted on the public AWS cloud, run by an Israeli company that's led by a former IDF spook – has plaintext access to the Signal chat logs they're archiving (along with chat logs for Telegram, WeChat, and WhatsApp).
SignalGate is even worse than we thought because they weren't just using Signal. They had this other insecure layer on top.
