"Österreichische Streitkräfte, die befähigt sind, die wahrscheinlichsten Bedrohungsszenarien langfristig abzuschrecken und im Ernstfall so lange durchzuhalten, bis Partner uns zu Hilfe eilen. Ohne Verbündete kann ein Kleinstaat im 21. Jahrhundert im militärischen Ernstfall nicht überleben."

Ein 🧵

Weil gerade wieder Doom-Saison auf allen Kanälen ist, und auch hier alles was „Rang und Namen“ hat, oder nicht hat, Doom-Meldungen und „Expertisen“ streut, hier was wirklich zählt.

Amateure reden über Orte und Gelände, Profis wissen aber, es geht um Logistik - und um Zeit.

„Es geht nicht mehr darum, Gelände zu erobern, sondern darum, funktionsfähig zu bleiben. Die Seite, die ihre Logistik stabil hält und sich nicht überdehnt, gewinnt Zeit – und Zeit ist die einzige echte Währung, die noch übrig ist.“

‼️Es geht schon lange nicht mehr um „Pokrovsk“ - es geht um ZEIT!

Norway finds out that its electric busses - produced by a Chinese firm - can be remotely controlled from China!

The good news of this is that the Norwegians realised this because they did a cybersecurity test. We need to think about, and test, stuff like this more.

Mal und immer wieder danke fürs "grounden".
Als Zivilist und ehemaliger Sozi mit Ostermarsch-Vergangenheit (ja, ich würde heute woanders marschieren) und sehr wenig Verständnis für militärische Zusammenhänge hilft es wirklich, nicht zu verzweifeln und weiter an das Gute (die Ukraine) zu glauben.

Is it time to update Coordinated Vulnerability Disclosure standards to be Coordinated Vulnerability and Patch Disclosure.

In the early days of L0pht/@stake we often had a Mitigation/Fix section in our vulnerability reports.

My latest cartoon for @newscientist.com

p.s. this week I am on a USA/Canada tour with my new book. Details and preorder links at tomgauld.com
Panel 1. image of a huge nuclear plant. “Reactor Overheating” 2. A worker in a hazmat suit works at a computer. The screen reads: “Press cancel to avoid critical overload” 3 - 9. The worker continues to type at the computer. The screen changes in each panel and reads: “Enter password to confirm” “Incorrect password” “Incorrect password” “Do you want to reset your password?” “Reset link has been sent to your email” “Please choose a new password” “New password can't be the same as old password” The colour gets hotter in each panel. Starting blue in 1 and ending in red in 9. Panel 10. Wide view. The entire earth is blown up.

Das diesen Leuten, die sowas auch noch teilen, das konstante Doom-Posting für Klicks nicht langsam selber zu blöde wird? 🤨

Seit 1‘344 Tagen machen die das schon, und diese Ukraine will und will nicht unter gehen.
