Net een -nog- voordeliger aanbod gekregen van mijne huidige elec/gas provider na het overstappen naar groepsaankoop. Klagen (en overstappen) blijft lonen.

The source code for the TM SGNL apps (basically a backdoored version of Signal used by Trump officials) is public! Since it's open source, I've pushed it to github for easier research micahflee.com/heres-the-so...

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.

Seems VRT was spreading misinformation about Signal in favour of Threema, which my old blog post also mentions is subpar compared to Signal.

Meta AI was forcibly enabled for EU whatsapp users. AI chat input is used to train the model. Use ‘ /reset-all-ais’ to clear the AI memory.

Fun fact: the latest Apple WebKit security patch was done based on a Reddit story of a user being targeted and reporting the original patch not begin sufficient. I flagged this to Apple Product Security, which I like to think is the cause of iOS 18.3.2 & macOS 15.3.2.

Apple retracting Advanced Data Protection from the UK after it requiring a legal backdoor should tell you everything you need for this E2E encryption feature. Get some yubikeys and enable it on your fruit ecosystem!

If you use Signal, take a moment and confirm you have this setting turned on. Trust me on this when I say it’s important.

Use Screen Security to prevent Signal previews from appearing in the app switcher on your phone. This is unrelated to the screen lock designed to lock your Signal screen so that you can't interact ...

Humongous shoutout to DIGI for finally challenging the gated telco monopoly situation here in Belgium. This is just amazing.
10Gbps duplex for 20 EU/m. Mobile for 5eu/month.
Executives at Proximus and Telenet are sure worried right now.
Digi Belgium is busy with a press conference
