Push-Benachrichtigungen und Datenschutz

Seit einigen Tagen werden Push-Benachrichtigungen und deren Implikationen für den Datenschutz heiss diskutiert. Auslöser war der Brief eines US-Senators ans Justizministerium (DOJ), worin gefordert wird, dass Betreiber von Push-Diensten – insb.

same reason for #Linux I guess and same reason why I do all the #OS1337 code in #bash with only .config makefiles where needed:

Readable and thus easy to #audit code allows for #transparency, which is vital for #maintainability and #security...

After all, mistakes do happen and I'd rather have it easy find and fix than optimize every bit at the cost of unmaintainable code.

Big Brother is watching you - now also via Google's & Apple's push. 🤬

LibreOffice supports symmetric and asymmetric encryption for OpenDocument Format (ODF) files.

Select File > Save/Save As

The "Save with password" option encrypts the file with AES-256.
The "Encrypt with GPG key" option encrypts the file with a public key.

New-ish Asus routers seem to enable "Yandex.DNS" by default. This forwards all of your DNS lookups to Yandex, a large Russian search engine. I discovered this on my dad's router when he had troubles accessing his bank from his broadband but not on his phone. (Presumably, the bank geoblocked Russian IPs as a protest to the invasion of Ukraine.)

I get that you need to trust someone with your DNS lookups (your ISP, Google, Cloudfare, etc), but I didn't expect the non-ISP option to be the default...

Check your router!

We're happy that #Apple has now joined the fight for encryption! 🔒

There is no magic key that allows the police to scan all chat messages, emails, and more for harmful content while not risking the security and privacy of everyone. This is technically not possible.

The more agree to this fact, the higher the chances that legislation is altered to protect everybody's privacy.

Mozilla: "In a well-intentioned yet dangerous move to fight online fraud, France is on the verge of forcing browsers to create a dystopian technical capability. It would force browser providers to create the means to mandatorily block websites present on a government provided list. Such a move will overturn decades of established content moderation norms and provide a playbook for authoritarian governments"

Interesting: ProtonMail finally admits that Germany "is a good choice given Germany’s strong privacy laws and culture that make it almost as strong as Switzerland."

For once, we couldn't agree more. 😀

We'd even argue Germany is much better as we do not have data retention laws (which would be against the German constitution) - while in Switzerland large tech companies are forced by law to retain data: https://tutanota.com/blog/posts/data-retention-germany

2FA-Secrets offengelegt: Google Authenticator bläst geheime Daten in den Äther

2FA-Secrets geleakt: Google Authenticator ist nicht ganz dicht

2FA, eine der wichtigsten Apps für die Sicherheit der eigenen Online-Welt hat offenbar Probleme den zweiten Faktor geheim zu halten.

^{Moritz Poldrack (Tarnkappe.info)}

Google has just updated its 2FA Authenticator app and added a much-needed feature: the ability to sync secrets across devices.

TL;DR: Don't turn it on.

The new update allows users to sign in with their Google Account and sync 2FA secrets across their iOS and Android devices.

We analyzed the network traffic when the app syncs the secrets, and it turns out the traffic is not end-to-end encrypted. As shown in the screenshots, this means that Google can see the secrets, likely even while they’re stored on their servers. There is no option to add a passphrase to protect the secrets, to make them accessible only by the user.

Why is this bad?

Every 2FA QR code contains a secret, or a seed, that’s used to generate the one-time codes. If someone else knows the secret, they can generate the same one-time codes and defeat 2FA protections. So, if there’s ever a data breach or if someone obtains access .... 🧵
