FOE
This is bad news for defenders because a feature designed for privacy is being bypassed, potentially exposing sensitive information.
Defender Context
This highlights the ongoing challenge of securing features that rely on client-side controls, especially when users can employ modified applications. Defenders should be aware that privacy features can be circumvented and that user reliance on end-to-end encryption does not guarantee complete protection against data capture via alternative means.
