Proton
Proton@ProtonPrivacy·
It looks like welcome progress has been made in the EU and existential threat to #encryption known as #ChatControl seems to be softening. Parliamentarians have reportedly agreed to remove clauses that give law enforcement a blank check to force encrypted services like #ProtonMail to hand over user messages, emails, and files. While this is a victory for the online #privacy movement, the devil is in the details, and we look forward to seeing the official text. It's vital the European Council aligns its position with Parliament now. Read our full statement here: proton.me/blog/eu-chat-c…

@HansVanEijsden @ProtonMail Ah neat, in this case you know that your setup already validates DNSSEC. We call this prefiltering, but we mostly saw it for web clients until now. In order to conduct the other tests, you can remove these 2 addresses from the list of To addresses. Hope this helps :)

@holzsec @ProtonMail Unfortunately, I'm unable to reply to the mail. See screenshot, my Postfix which checks for DANE/DNSSEC refuses to send because of the two broken domains and gives back the error to my SMTP client 😉

Test your email provider on email-security-scans.org! We are still looking for the first one to score 10/10 - While waiting for your result, have a look at the blogpost! My setup at @ProtonMail -> Strict TLS support ✅ (! DANE < MTA-STS); IPv6 for DNS 🏗️ / 📧-delivery soon?

⚠️A while ago I developed Heimdall-WiFi-Radar, only with 3× ESP8266 it was possible to track and position WiFis devices through walls, now with the help of AI we have a new level, it is possible to know where you are and what are you doing! 😱😱
