> Microsoft has the government locked in as a customer, so the government’s options for forcing change at Microsoft are limited, at least in the short term.

This applies to the states of the 🇪🇺 and many other countries as well. But the bigger problem is: Nobody seems to care. Many times people just shrug and say that we can't change that anyway. ¯_(ツ)_/¯

To me it's the same situation as with the 🌡️ . You can make the change. Switch to such as a :linux: / system, support projects through contribution and donation, and never trust the cloud (other people's computers).

No or "genius" at or other company will save the world or protect you from . It's up to you and it's your responsibility to make the change. 🛡️ is a process that begins with your to it, and the is no sandpit (anymore).

Gestern hat Golem über Probleme im eID-Verfahren berichtet.
Zitat: „…dass die Sicherheit des eID-Verfahrens im Wesentlichen von jener der Client-Seite abhänge.“

Ich hatte mit dem System mal beruflich zu tun, wollt Ihr ne Story?

Im wdr wird mal wieder berichtet, das ein „Hackerangriff“ die Computer eines Klinikums lahm legt.

Liebe Journalisten, bitte schreibt doch nicht immer solch einen Unfug!
Hackerangriffe legen gar nichts lahm, die werden oft jahrelang gar nicht bemerkt.

Das was ihr meint ist folgendes: „Im Klinikum XY hat eine Mitarbeiterin auf einen Link geklickt. Leider wurde am IT-Betriebskonzept gespart, weswegen jetzt alles kaputt ist.“
Die Überschrift lautet also: „Klinikum offline - mangelhafte IT verhindert Betrieb“ o.s.ä.

Reading about the recent SMTP and SSH vulnerabilities, I get the impression that open source projects, proprietary vendors and government agencies such as @certbund don't know how to talk to each other. They should at least have something like a red phone.

Please comment here if you have a constructive idea on how to improve the situation! #SECconsulting seems to assume that everyone uses #VINCE, a CMU service I had never heard of.

screenshot from the Postfix website: SMTP Smuggling [An updated version of this text may be found at https://www.postfix.org/smtp-smuggling.html] Author: Wietse Venema Last update: December 23, 2023 Summary Days before a 10+ day holiday break and associated production change freeze, SEC Consult has published an email spoofing attack that involves a composition of email services with specific differences in the way they handle line endings other than . Unfortunately, criticial information provided by the researcher was not passed on to Postfix maintainers before publication of the attack, otherwise we would certainly have convinced SEC Consult to postpone publication until after people had a chance to update their Postfix systems. …
screenshot from the Terrapin website: … Aside from the SSH implementations marked with an asterisk, we included the following implementations, vendors, and CERTs in our responsible disclosure process. Due to the lack of proper security contacts and response, we were not able to disclose our findings to some of them. AbsoluteTelnet (Celestial Software) Amazon AWS CERT-Bund Cisco Ericsson Microsoft Mikrotik Partnered CERTs of CERT-Bund (via CERT-Bund) SSH Server for Windows (Georgia Softworks) Tectia SSH (SSH Communications Security, Inc.) Termius (Termius Corporation) The selection of SSH implementations contacted during responsible disclosure was based on several factors. We aimed to achieve a decent coverage of "strict kex" on public disclosure by focusing on the underlying SSH implementations. We gathered all SSH implementations listed in publicly available resources (Wikipedia SSH clients, Wikipedia SSH servers, Quendi SSH implementation comparison) as a baseline. …

So, friend of mine just fell for a phishing text message pretending to be the mail service, advising him that a delivery had failed - and besides the fact that even savvy people like said friend can be fooled, there's a question: How the f**k do the Bad Guys™️ know that we were expecting delivery from that carrier, even at exactly that time, down to phone number & email...?

This was far too on-the-nose to be coincidence. Somebody in the chain has a leak.

Not because it's #solutionism at it's worst aka. #web3...

But because it has serious issues in terms of #ITsec & #InfoSec:

After disabling URL previews in Signal for security reasons, I wanted to do the same in #Element just to be on the safe side.

Locating this option took me quite a while because I did not expect it to be tucked away under the “Images, GIFs and videos” section heading.

Here is the full click path:

Settings → Options → “Images, GIFs and videos” → “Enable inline URL previews by default” → no

Opened Firefox on Android.
Get "Decentraleyes has been added to Firefox" overlay with "Open it in the menu", "Allow in private browsing" and "OK, Got it".

Problem is I didn't try to install this extension.

Is this just more Firefox providing misleading info?
Perhaps after an update on an Extension that I had installed and switched off years ago?

Or is some worse happening?

(Not keen on the Firefox help forum. Negative prev experiences there.)
