Usage-inflation Attack

NOTICE: This attack is applicable to ISPs that account for TCP retransmission. As of November 2013, the majority of ISPs (outside of South Korea) blindly account for every IP packet regardless of TCP retransmission.

The "usage-inflation" attack arbitrarily inflates the cellular data usage of a target subscriber by intentionally retransmitting packets in the flow even without actual packet losses.
