DID THE GCSB EVER INVESTIGATE THE BRASH EMAIL COMPLAINT?

We wonder, we also wonder why in 2006 the GCBS's Centre for Critical Infrastructure Protection listed NINE significant cyber incidents.

In 2008 there were TEN significant cyber incidents listed.

But in 2007 the GCSB did not list the number of significant cyber incidents.

We would like to know:
What constitutes a significant cyber incident.
Why the number of significant cyber incidents for 2007 where not listed.

And we tried to upload the annual Reports but SCRIBD says they are encrypted and password protected.. So sorry, you will have to go to links to read the info.
