Switzerland is a great place for doing experiments at altitude, in a literal and metaphorical sense.

I wonder what is the digital sovereignty strategy of federal research institutions, #EPFL and #ETHZ?
Is it enough to keep the data hosted locally, while metadata and services themselves - not?
Is development of strong independent technological foundation important?

La Confédération affirme vouloir "réduire progressivement et à long terme sa dépendance vis-à-vis de Microsoft", rapportait dimanche la NZZ am Sonntag. À rebours de ses décisions des dernières années, cette annonce est saluée par plusieurs politiques et spécialistes.

Das können wir durch anekdotische Evidenz untermauern. Beim Besuch unserer über 10 Jahre alten #Wiederaufforstung in Costa Rica kann man diesen Kühlungseffekt bemerken.
Dazu trägt auch die Laubschicht auf dem Boden bei, wodurch Wasser verdunstet.

[en] Signal #messenger: "two practical attacks that break the integrity properties of #Signal in its advertised #threat model" - Patched
Paper #ETHZ
"... protocol for resolving identities based on usernames and on phone numbers introduced a #vulnerability that allows a malicious server to inject arbitrary messages into one-to-one conversations under specific circumstances"
"The second #attack is even more severe. It arises from Signal's Sealed Sender (SSS) feature, designed to allow sender identities to be hidden ... a combination of two errors in the #SSS implementation in #Android allows a #malicious server to #inject arbitrary messages into both one-to-one and group conversations."

Signal is a secure messaging app offering end-to-end security for pairwise and group communications. It has tens of millions of users, and has heavily influenced the design of other secure messaging apps (including WhatsApp). Signal has been heavily analysed and, as a result, is rightly regarded as setting the "gold standard" for messaging apps by the scientific community. We present two practical attacks that break the integrity properties of Signal in its advertised threat model. Each attack arises from different features of Signal that are poorly documented and have eluded formal security analyses. The first attack, affecting Android and Desktop, arises from Signal's introduction of identities based on usernames (instead of phone numbers) in early 2022. We show that the protocol for resolving identities based on usernames and on phone numbers introduced a vulnerability that allows a malicious server to inject arbitrary messages into one-to-one conversations under specific circumstances. The injection causes a user-visible alert about a change of safety numbers, but if the users compare their safety numbers, they will be correct. The second attack is even more severe. It arises from Signal's Sealed Sender (SSS) feature, designed to allow sender identities to be hidden. We show that a combination of two errors in the SSS implementation in Android allows a malicious server to inject arbitrary messages into both one-to-one and group conversations. The errors relate to missing key checks and the loss of context when cryptographic processing is distributed across multiple software components. The attack is undetectable by users and can be mounted at any time, without any preconditions. As far as we can tell, the vulnerability has been present since the introduction of SSS in 2018. We disclosed both attacks to Signal. The vulnerabilities were promptly acknowledged and patched: the first vulnerability was fixed two days after disclosure, while the second one was patched after eight days. Beyond presenting these devastating attacks on Signal's end-to-end security guarantees, we discuss more broadly what can be learned about the challenges of deploying new security features in complex software projects.
Introduction to #Linux (Tomorrow, 10.03.26):
In this course you will learn about the wide family of free operating systems based on the Linux kernel, some of the most useful software tools available for them, as well as the philosophy that made them so successful.
Find out how easy to use and yet powerful Linux systems are, discover their advantages when compared to other operating systems, and get to understand their basic structure and most important concepts.
Furthermore, discover different flavours of Linux and get a feeling for which #distribution and desktop environment would be the right match for you.
