> +save observed QUIC packets for an offline attack against QUIC packet protection
+at a future time; this is true for any observer of any packet on any network.
+
+
+#### 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.

Reworded and moved this around to hopefully be more clear
