The last I spoke with NTT they said the largest they ever saw was > 300GB
and most of the time they don't follow through. They threaten 100 networks
and hope that x% will pay them off 'just in case'

They lie.  The largest attacks we've seen from these threat actors are in
the ~60gb/sec range - which is nothing to shake a stick at, mind.

Many times, they don't follow through.  But you're right to be prepared.

See these two presos:

I would really appreciate help in a few areas (primarily with certain
provider contacts/intros) so we can execute our strategy (which I can't
reveal here for obvious reasons).


All this super-secret squirrel stuff doesn't help, it's actually a
hindrance.  The short answer is 'upstream ACLs'.

Nevertheless, contact me 1:1 and I'll work to hook you up with the right
folks.
