You will still see backscatter which will let you know your space is being spoofed as well. This will show in your telemetry. Sent from my iCar

How would they know what to look for?
I'm assuming Sony isn't cooperating.

If someone is being spoofed, they aren't receiving the spoofed packets. How are they supposed to collect anything on the attack?
Offending host pretending to be Octolus -> Sony -> Real Octolus.

It is impossible to find the true origin of where the spoofed attacks are coming from.
This is demonstrably untrue.
If you provide the requisite information to operators, they can look through their flow telemetry collection/analysis systems in order to determine whether the spoofed traffic traversed their network; if it did so, they will see where it ingressed their network.
With enough participants who have this capability, it's possible to trace the spoofed traffic back to its origin network, or at least some network or networks topologically proximate to the origin network.
That's what Damian is suggesting.
