The app first got here out in September 2021, however after an replace the next August, it started recording a minute of audio each quarter-hour and forwarding these recordings, by way of an encrypted hyperlink, to the developer’s server. The entire thing is documented in a blog post from Important Safety in opposition to Evolving Threats (ESET) researcher Lukas Stefanko.
