Wie, Du bist nicht bei Whatsapp?

“Wer Whatsapp liebt, sollte besser nicht weiterlesen, oder vielleicht gerade dann, denn Liebe macht ja bekanntlich oft blind.” Boris Pohler, selbst Lehrer und Vater von zwei Kindern, bennent den Preis für die Verwendung des weit verbreiteten Dienstes und erklärt, warum jeder Nutzer gegen deutsches Recht verstößt.

How not to get phished

“Most humans can tell the difference most of the time, but if they are tired, or stressed, or in a rush, or have any number of other common obstacles to computer use, there’s a good chance they won’t notice the difference, will type their password into the wrong site, and will have their account taken over by bad guys.” Jacob Hoffman-Andrews identifies password managers as the average human’s best defence against phishing attacks.

Conversations

“Welcome to this introduction to Conversations. It is gonna be a great introduction. It’s gonna be fabulous. Other instant messengers have fought Conversations for many years, but they couldn’t beat it. Just couldn’t do it. Total loosers. They’re all dead now. All the other messengers have failed. Forget WhatsApp, okay? Signal …total disaster. Threema is so bad, it’s not even a real messenger. It’s fake. Threema is a fake messenger. Converstations has got to be the best messenger in the world. It’s huge. OMEMO. You’ll love it. Best protocol. Tremendous. Absolutely fantastic. Nobody has messengers better than Conversations. This messenger is so big, you can even see it from the moon. And I am going to make you pay for it. It’s true. Important people tell me that Conversations is so great, it’s unbelievable. So great, it’s beautiful. Conversations is the best instant messenger that God ever created.”

Signal

“I am regularly impressed with the thought and care put into both the security and the usability of this app. It’s my first choice for an encrypted conversation.”
Bruce Schneier

Signal offers private messaging and calling in one simple app. It is both free and open source. Development is supported by community donations and grants. This means that there are no hidden strings attached. Use Signal as an alternative to WhatsApp or, better still, its replacement.

Threema

“Threema is a mobile messaging app that puts security first. With true end-to-end encryption, you can rest assured that only you and the intended recipient can read your messages.” Threema is my favourite instant messaging application and has been described as “a much flasher version of WhatsApp”. Its source code has recently undergone an external security audit and was found to provide a ”security level which compares favourably with the state of the art in similar messaging services“.
