> +#### Active Attacks
+
+An active attack ({{?RFC3552}}) involves writing data to the network.  An
+attacker with such a capability might be in a position to additionally prevent
+the original packets it observes from reaching their intended destination.  If
+so, they are considered to be an on-path attacker.
+
+An active attacker may also choose to rewrite the source or destination IP
+addresses of packets that it forwards or injects. Such spoofing attacks are only
+effective against a QUIC connection if the attacker can still forward the
+contents of the packets to the original endpoint, since QUIC connections are
+both authenticated and encrypted.
+
+A blind attacker, one who injects packets without being able to observe valid
+packets for a QUIC connection, is unlikely to be successful, since QUIC packet
+protection ensures that valid packets are only generated by endpoints which
