The exploit
-----------

This library has the very specific target of undermining the security of the
"internet of things". It was designed to be attractive to being integrated into
IoT hardware platforms where it will be difficult to patch once it is
discovered.  The backdoor also has a fairly strong degree of 
deniability. It arises from a rare, yet plausible bug. It would be very hard to
establish malice as opposed to simple oversight on the programmers part once the
exploit is publicly discovered.
