These are stupid design decisions made by engineers who had no idea how to create a secure system.
I know that there's an old saying about not attributing to malice what can be explained by stupidity, but there's also a saying that 3 times is enemy action. Given the world we now live in, the most conservative analysis should be that DTEN is, wittingly or unwittingly, actively engaged in industrial espionage. If they as a company are not involved, I would expect some very public terminations of the managers who were in charge of these systems and any engineers who did not speak up regarding the poor security practices. Otherwise, I don't see why any company would buy and use DTEN products with any level of trust that their data is in good hands. 6e08b7e5a96f13fb9da31a93e85d2ddb7115d1de425c8b80f1f61e4d7733947e
