Compared with the distributed denial of service attack that directly forges the source address, the reflection attack is more difficult to trace the source of the attack due to the addition of a reflection step. However, this is not the real threat of the reflection attack, and the real threat lies in the amplification attack using the reflection principle.Finally: Summarize APT attacks again:黑道组织铁船帮帮主越西鸿手下有十三鹰，全都武功高强。江湖大侠司马鑫受人敬重，越西鸿一直欲除之而后快，但又不敢轻举妄动。越趁司马鑫女婿卓一帆外出之际，率十三鹰将司马鑫、其女儿司马玉琴等全家人杀死。戚明星是十三鹰之一，因对帮主乱杀无辜不满，叛逃中正遭铁船帮追杀。戚逃至沙漠，见一受伤青年昏倒在地便将其救起，此青年乃司马玉琴的丈夫卓一帆。两人栖身沙漠一小屋内，联手将追至此处的铁船帮杀手统统歼灭。随后，他俩直扑铁船帮总坛，与帮主在堂上展开一场恶战，终将越西鸿毙命。Ten, Terrain Modeling, Road Projection and Surface Plant GenerationHow fast is 5G mobile phone? What changes can it bring to our life?/grin (grin)The sockstreet attack first completes the tcp three-way handshake the tcp connection is established, but in the last ack reply of the three-way handshake, the attacker sets its tcp window to 0 and then makes a data request. When the target discovers that the TCP window size at the receiving end is 0 when transmitting data, it will stop transmitting data and issue a TCP window probe packet to ask the attacker if its TCP window has been updated. Since the attacker does not change the size of the tcp window, the target will always maintain the tcp connection waiting for data to be sent and continuously carry out window update detection. If the attacker uses a large number of controlled hosts to carry out sockstreet attacks, the target will always maintain a large number of tcp connections and carry out a large number of window update detection, and its tcp connection table will gradually run out.
