If it's stupid and it works, it isn't stupid.

Todd, have you verified this "encryption" specifically the statement
by McAfee:
"One of the malicious programs opened a remote backdoor to the
computer, establishing an encrypted covert channel that masqueraded as
an SSL connection to avoid detection."

I assume by masquerade they mean the fact it is communicating over
port 443 with some simple XOR'd bytes to form commands for performing
various actions ranging from process to file manipulation and updating
etc...

There are by far better exploits and malware in the world and used
even by joe botnet operators than this IE0day and malware.

Can you explain how this is sophisticated. It looks to me like most
decent malware samples I've RE'd:

The result: triple encrypted shell code which downloads multiple
encrypted binaries used to drop an encrypted payload on a target
machine
which then establishes an encrypted SSL channel to connect to a
command
and control network.

If they are so sophisticated and organized, then why do they
continually
get noticed shortly after the attack. A major element that you
fail to
realize about these so called sophisticated attacks is stealth and
persistence, which this attack lacks.
