ISIS uses steganography and public websites for operational communications.
There’s no way to shut that down because the messages are invisible. Impossible to detect that the messages are even being exchanged, let alone with information they contain.
They could be communicating through pictures posted on FR and we’d never know it.
Monitoring that kind of communication is ostensibly what the NSA is supposed to be doing. Instead the NSA is monitoring you and I.
Its difficult but not impossible when you feed a ton of information into a massive data analysis machine.
“They could be communicating through pictures posted on FR and we’d never know it.”
Very true, but still we could make it harder. And theres no excuse that they have facebook and twitter presence and email names. As soon as one is identified it should be killed.
We do nothing to cut off their communications nodes.
