Hathaway_Noa my friend im hundred percent on what you say about don't rely on titan. This is what i also recommend and do.
Now on the subject of law enforcement. Most of them, even at the federal level, have no idea about infosec. They are specifically trained in groups and most of the tasks are done by external companies. Such as Cellebrite, grayshift, pegasus etc. I also have chats where authorities claim to be able to decrypt signals over the air. Do we want to discuss this also? That's why I've talked about the court case several times. Because that's the only thing that matters. There is a criminal procedure. It must be possible to verify the integrity of the data, otherwise it cannot be used. It must be ensured that the data has not been altered. This is only possible if every step is precisely documented and reproducible. This means that the complete technical process must be verifiable on request. Otherwise, even the dumbest defense lawyer can question the integrity of the data. All this was encrochat and Sky and now anom not possible because the prosecutors have used a simple trick. The source of the data are countries where these disclosure laws do not exist. It is simply said that the investigating authorities and courts that produce the source of the data are trusted to comply with all laws.
As a simple example related to Germany. Here, an investigating judge is not allowed to order a so-called source telecommunication surveillance. Only a criminal court can do that. In Germany, the encro hack would have been legally impossible to implement. The criminal procedure order was deliberately circumvented by them.
After all the defense lawyers in Germany had to watch stunned as their clients were sentenced, they founded an association that has collected everything in German criminal law that is relevant. And according to the current status, Cellebrite must describe such a circumvention in detail in court.
In Holland, the laws are even stricter. In short, the chat with an official there is hot air until it comes to court. Just ask him for a file number. In court he would have to explain how they do it. This is why such vulnerabilities get closed soon as they hit the court. This doesn't apply to all countries. But Germany, Belgium, Netherlands. Belgium has imposed an absolute ban on the use of evidence over encro.
