This is such a golden opportunity for each of you to find compromised
hosts on your network or your customer's network.  The number of
genuine lookups of the blog vs the number of botted machine would
make it almost certain that anything directed at the blog is a
compromised machine.  A phone call to the customer / further analysis
would reduce the false positive rate.

This time around its not about spoofing.

I presume this is development of the same botnet/worm that we seen day2 of
Shellshock public disclosure - its was pretty hightech - golang,
arm/mips/x86 support, multiple attack vectors - inlcuding (surprisingly)
very effective password guessing.
It counted  ~100k heads on day2,  and i suppose they did grew quite a bit.


Thats part of a problem why cause that much havoc - they do have real IP
addresses and reasonably well conected - so they can wreck a havoc in
bandwidth and tcp stack.

They most likely do not have enough resources to do Full Browser Stack,
thats why I think  L7 capabilities of the botnet will be very basic.

This is not strictly true.  If it could be determined where a large
bulk of the spoofing came from, public pressure could be applied.  This
may not have been the issue in this case, but in many amplification and
reflection attacks, the originating spoof-enabled networks were from a
limited set of networks.  De-peering, service termination, shaming, etc
could have an effect.
