The attacker first completes the three-way handshake to establish the connection, but in the last ACK reply of the three-way handshake, the TCP window size is set to 0, and then a data request is made. When the attack target sends the request result to the attacker, it stops the data transmission when it finds that the TCP window size is 0, and sends out a TCP window detection packet to ask the attacker if the TCP window has been updated. Since the attacker will not update the window size, the attack target will always maintain the TCP connection and wait for the data to be sent, and continuously carry out TCP window size detection. When the number of controlled hosts in the botnet is large, Target's connection table will gradually be exhausted, resulting in denial of service.少女玛丽·阿德勒（凯特琳·德弗饰演）报警说自己在家中被一名闯入者强奸，但调查人 员以及她身边的人都怀疑这件事的真实性。与此同时，在数百里外，侦探格雷丝·拉斯马森 和卡伦·杜瓦尔（分别由艾美奖获得者托妮·科莱特和梅里特·韦弗饰演）在调查两起非常 相似的强奸案时相遇，她们合力追捕这名潜藏的连环强奸犯。The fighting situation at position 149 to be talked about next is many different from that at positions 169 and 142 mentioned earlier, because for the first time there is a "flying unit" among the "living biological weapons" appearing at position 149.Callie and Arizona have to make a choice regarding surrogacy while the board has to decide whether to give Cristina's seat on the board to Alex or Bailey.
