/*

listen test - listen on ports / allow incomming tcp/connections wiith a customm tcp/ip stack

this is another side of mass surveillance platforms being weaponized...

specific sockets which are listening on specific ports which can be turned on/off at will algorithm wise..
the rest of the IP can function normal to its server..

I planned to use this for automated hacking + worm-ing the world but they .. why not just give it away?

The point is that if you are able to filter specific ports from a 'target IP' then you can redirect to this custom TCP/IP stack
which will allow C&C which has nevver been seen before because .. it functions 100% proper, and normal...
the IPs, and ports can change.. it TRULY is 100% untracable, but also available worldwide... the HOPs, etc
can be manipulated (thats the only new portion of this for the  last two years that i came up with recently),

oh one other new development lately... it can be secured by tcp options, or a few other features that i dont want to discuss yet
any ISP worldwide can prepare this setup, or any passive internet monitoring system... its unstoppable in every way possible

the entire system can and should be controlled by an algorithm.. nobody could ever figure it out woithout inside knowledge
it can allow secure communication, drops, etc which can never be found againn.. and with proper encryption the logs
would be irrelevant... it can take advantage of real live servers (facebook, etc) and nobody would be none the wiser
or ever suspect anything.. well time for the world to see just how dangereous mass surveillance systems are...
BEYOND mass surveillance..
