We appear to be going round in circles on this topic.
The exploits discussed here are widely available to be viewed on much more popular sites.
Customers with a need for high security will already have their own IT experts (in theory) securing the network. If not, frankly that is their poor decision, not their 'physical' security suppliers, as most here will sell with a disclaimer re: open or remote access.

It is highly unlikely this forum is a used or useful site for criminal activity.
*Although I appreciate it's pretty much a universal problem, to varying degrees
