Three billion WhatsApp users are at risk - an expert has developed a tool that could spy on everyone, and you would never know about it
By knowing only a phone number, an attacker can repeatedly probe a device without sending visible messages or triggering notifications.
Silent Whisper operates below the user interface, making detection unlikely during normal phone use.

For people forced to use #WhatsApp
WhatsApp's usernames with PIN protection remain available only in beta versions as of late 2025. No stable public rollout has occurred yet, despite ongoing testing across Android and iOS betas.

@kuketzblog 2/2 Für Leute die #WhatsApp nutzen müssen
In der WhatsApp-Beta für Android und iOS können Nutzer einen einzigartigen Nutzernamen reservieren, der anstelle der Handynummer für neue Kontakte genutzt wird. Andere sehen dann nur diesen Namen, nicht die Nummer, und es gibt optionale PIN-Schutz für Nachrichten von Unbekannten.

@kuketzblog P.P.S.:
"For people who want to restrict delivery receipts, Signal already supports disabling phone number discoverability (Settings > Privacy > Phone Number > Who Can Find Me By Number). With this setting enabled, you can choose a random alphanumeric username and no one will be able to send you any messages (delivery receipts or otherwise) unless you share that username with them."

2/3 "We understand that Signal cannot be everything to everybody. If people are concerned about this, as previously mentioned, you can disable discovery in the settings. If someone's threat model includes concerns about network activity in general (because let's be clear, there are many other potential vectors to consider depending on your specific threat model), we recommend using a VPN."
