Gen Digital researchers have disclosed GhostPairing, a technique that leverages WhatsApp’s multi-device functionality via social engineering to enable persistent, low-noise access to user communications.

The case highlights how legitimate features can become attack surfaces when paired with deception rather than technical exploitation.

Open discussion: how can platforms mitigate abuse of trusted workflows without degrading user experience?

Researchers disclosed that delivery-receipt behavior in WhatsApp and Signal can be leveraged to observe device activity using silent reactions, edits, and deletions.

Only a phone number is needed, and there’s no user control to disable receipts.
What types of safeguards would you consider appropriate here?

Swedish government wants to get access to your encrypted messaging communication.
Exactly how are they thinking of doing that?
I am no tech specialist, even I have been online since early 1990s. I may very well miss something or be ignorant of some aspects, but..

OK, let's say Swedish government wants backdoors to messaging apps.
Signal refuses and leaves Sweden.
So, is the Swedish government going to demand that of everyone messaging app?
Signal, WhatsApp, etc, they are centralised, so could perhaps work.

But what about smaller, "unknown", decentralised messaging services? Like SimpleX? How are you going to get them to comply?

Or XMPP/Jabber with OMEMO encryption? That is a not an app, not even a messaging service, but a protocol, similar to email.
Do you think every developer of an XMPP app is going to comply? That is, if you are even capable of finding them? And that goes for the XMPP servers, as well. "Anyone" can set up an encrypted XMPP server.

Gearing up for some more development on encrypting and decrypting messages for kids.

Just renamed my one-time pad encryptio library to something that was possible to remember:

otp-encryption-js

First thing is to make emojis unique over different versions of unicode emoji versions.

Then look at one-time pad exchange between phones.

iMessage and Secure Communication

In the process of updating my blog to align with Fediverse standards and protocols, I realized that iMessage could be a great option for secure communication. I wasn’t aware that you can prompt a link to open a new iMessage chat.

By creating a disposable iMessage alias and disabling unknown FaceTime calls, you can keep your contact information accessible while maintaining clear boundaries. 🙂
