Threema

number one is have a look at what apps you have installed if there's anything that you don't use anymore remove it because over an extended period of time those apps get vulnerabilities and that vulnerability could be a backdoor into your entire phone the second thing is if you feel like you're an at-risk person then using more secure communications is probably a great start If you're just messaging your friends about a barbecue, WhatsApp and message is perfectly fine.

But if you're doing something more sensitive, then definitely consider using more secure messaging apps like Signal or Threema or many of the other options that are available.

seen any examples of the Pegasus spyware in Australia? So I've spoken to security researchers and they've told me that since March this year, more than 250 individuals, journalists, politicians, activists, lawyers have actually been notified that they have mercenary spyware on their phone.

Who notifies them? So if you have Apple on the latest iOS, Apple and Google have taken what we call indicators of compromise from Citizen Lab, which is a group of security researchers that are funded by Amnesty International and Amnesty's International Security Lab to actually identify these fingerprints of the various different mercenary spyware that are out there around the world.

Freema is another new integration.

It lets automation send end-to-end encrypted messages to people on Threema, the privacy-focused messenger that does not need a phone number.

It uses the Threema gateway service, and each person you add as a recipient gets their own notify entity.

A notify entity is a target Home Assistant can send notifications to.

Willow connects Willow plant sensors to Home Assistant.

Yeah, look at that.

Uh, Threema.

Send end-to-end e-encrypted message from your automations to people on Threema.

Um, it's a privacy-focused messenger that doesn't need a phone number.

It uses the Threema gateway service, and each person you add as a recipient gets their own notify entity.

I have never heard of Threema.

This is, uh-

I'm glad you haven't.

Telegram sends codes to existing devices, WhatsApp requires the sign-in to start inside the app, and Signal uses QR codes that can still be scanned without physical access.

Testing began in late 2023, and the strategy became permanent for all agents in August 2025 covering WhatsApp, Telegram, Threema, and Signal.

The advice for users is simple.

Check your active sessions and remove any device you do not recognize.

So I just simplified.

That's when I also dropped Threema and a few other platforms.

More niche ones.

But yeah, it was that kind of a problem, like constantly losing messages or group chats don't load messages until I open the group chat or notifications don't come through until I open the app or just all those incidents.
