Personne n'aura autant fait pour populariser France Connect auprès du grand public que le sénateur Duplomb.
Très triste aujourd'hui.

Très grand chercheur en informatique et pédagogue exceptionnel, il a été pour moi l'un de ces professeurs qui marquent et qui aident à trouver sa voie.

Merci pour tout !

Watching Spain and Portugal very closely, but please don't jump to conclusions. Lots of bizarre root causes in big power grids.

From one of the leading figures in industrial cyber security 👇

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.

We don’t yet know

Aujourd'hui, j'aimerais revenir sur cette annonce qui a fait le tour des rédactions et des réseaux sociaux :

"On a enfin trouvé des indices liés à vie sur une autre exoplanète !"

Comme d'habitude, des affirmations extraordinaires nécessitent des preuves extraordinaires.

On en est loin ici.

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.
In case you missed it: the Pentagon--that's Hegseth--got warned about using Signal a week ago.

☀️ We've got a big new report out today☀️

A subset of the Russian info op known as "Portal Kombat" appears to be constructed not for human consumption, but machines.

NEW: We’ve uncovered something alarming: a Russian-backed disinformation network, known as the Pravda network, is flooding the internet—and LLMs—with pro-Kremlin propaganda. Our new report reveals how this growing operation threatens democracies worldwide. www.americansunlight.org/updates/new-...
