ISIS and EBOLA connection?

I remember about a month or so ago there was an interpretation of a statement made by Al Queda or ISIS and it had to do with the "next 9/11 style attack".
they promised it would be exponentially larger and will not be from the air or over the ground but rather from the inside out.
I also remember worrying that this would be most likely a biological approach and the 'inside out' was referring to ourselves and our bodies.
I cannot be the only person who read the report and also feels this is too coincidental.
watching these half-baked beheading videos while all the works are put in place to catch us while we're not looking.
thanks for listening and appreciate any thoughts or concerns.
