Das ist ein kleiner Sieg und vor allem euch zu verdanken! Die nächste Abstimmung ist für Dezember geplant - jetzt ist es wichtig den Druck bis dahin hoch zu halten.

What a great set of awardees for the #Levchin prize 2026
🏆 Whitfield Diffie and Martin Hellman for the invention (and publication 🤭) of Public Key Cryptography 🔐
🏆 The Tamarin team for the developement of the Tamarin prover and its use in verifying security protocols
Well-deserved 👏
Hier erklärt das Max Planck Institute for Security and Privacy kindgerecht, warum #Chatkontrolle eine sehr sehr schlechte Idee ist.
Das ist wichtige Arbeit, weil es auch nach drei Jahren „Diskussion“ immer noch Politikerinnen gibt, die es nicht verstanden haben.
EU muss endlich die #ChatkontrolleStoppen!
Falls nochmal jemand das Märchen erzählt, das Client-Side-Scanning der #Chatkontrolle sei kein Angriff auf Verschlüsselung, bitte schickt ihnen dieses FAQ:
https://csa-scientist-open-letter.org/FAQ
Wissenschaftler*innen versuchen es jetzt der Politik schon wirklich so einfach wie möglich zu machen, damit sie diesen total fehlgeleiteten Angriff auf sichere Kommunikation endlich aufhalten.
#ChatkontrolleStoppen
I just received this update on ChatControl from @carmelatroncoso @bpreneel @cascremers and Anja Lehmann:
Here is a new update. As you might know, there is no consensus still on the Chat Control regulation. The next two weeks are crucial. On October 8th there will be a non-public meeting where states will reveal their vote intention, with an actual vote on October 14th.
[...]
As of today, we have no guarantee that the regulation will be rejected. In fact, we have never been closer to acceptance, as several countries with major impact on the vote are reverting their previous position to reject or abstain. [...]
What would help right now is to either raise more public awareness, for example through the press, to put public pressure on governments; or directly contact your representatives, opposition parties, or relevant ministers, to bring awareness to the issues.
[...]
And we have created an FAQ to make it more accessible to press and politicians: https://csa-scientist-open-letter.org/FAQ [...]
If you can spare time to take any of the above actions, please do. Every little push counts.

Countries that are opposing the Danish chat control text:
Austria - strongly opposing
Poland - strongly opposing
Luxembourg - strongly opposing
Estonia - but needs support to stay opposing
Czechia - but needs support to stay opposing
Countries that are undecided, abstaining or ambivalent - need to be pressured:
Italy – undecided, we think there is a chance for an abstention
Finland – undecided / rumoured to be opposing, we think there is a decent chance for opposition
Germany - undecided / rumoured to be close to acceptance
Netherlands – they are confirmed abstention, this cannot change in time for the vote
Latvia – rumoured to be opposing, but the last official notes showed them supporting
Greece – silent, but have supported in the past
Slovenia – silent, but have opposed in the past
Countries that have only recently started supporting the Danish text, or that support it but have had concerns, so could maybe be convinced to change position, or at least abstain:
Belgium - recent support
France - recent support
Lithuania
Croatia
Malta
Portugal
It doesn't look good. Not at all. Please do anything you can, this situation is so ridiculous that I find it difficult even to explain it to Average Joe.
Renommierte Forscher:innen erinnern die Mitglieder des EU-Parlaments und des EU-Rates daran, dass die Chatkontrolle „beispiellose Möglichkeiten für Überwachung, Kontrolle und Zensur“ bieten würde. Sie fordern, die Ursachen von sexualisierter Gewalt an Kindern zu bekämpfen statt Hunderte Millionen Menschen zu überwachen.

We (over 500 scientists) have put (yet another) open letter to the EU commission online, detailing while we do not believe anything has changed in the recent iteration of #chatcontrol proposals that would make it any less unsafe: https://csa-scientist-open-letter.org/Sep2025
Please boost. Next week there will be (another) decision!

400 scientists speak out against chat control
Researchers from 33 European countries protests against mass surveillance on end devices. They warn that it is of little use and endangers everyone's safety.
