A little blog i wrote on how you can quickly unpack the storm worm packer, the one using code and IAT on heap.

Nothing really complex, just thought i'd share for people interested:

Yes it does.
But from what i saw, it's not morphine.
This sort of technique gets more and more common, the loader uses no fancy headers in order to bypass heuristics.
