Yep. It sounds like the packets were coming from this nic and the backbone routers had no logic to filter out those kinds of invalid packets. No SRC/DST/TTL should be a big red flag, but it seems like they didn't have a rule for that.

Talk about a needle in a hay stack.

Traditional IP filters are typically useless against packet storms because all of the packets are technically valid, there are just way too many of them.
