If anyone would like the SNORT sig we're using to sense 'bots
phoning
home
for control instructions, just drop me a line.  Am not sure posting
it
here
would be wise - too many lurkers who might like to subtly alter
this
overused variant to counter the sig.

When this triggers an alert on your SNORT, the bot is just waking
up
and
still benign (relatively speaking) and can be removed before the
'owner'
wakes them up and uses them to do harm.
