If there are more parameters, they will be stored on the stack. Therefore, in order for the computer to run the commands we want, we need to find a way to put the address of "/bin/sh" into RDI so that the machine can execute the system function. After carefully examining the linux function stack structure, we can find that we can use RAX register to put the system () address into RAX, then look for code fragments with JMP rax to make use of, and at the same time use RDI register to pass the parameter "/bin/sh" to finally achieve the attack purpose.As shown in the above figure, the server side provides NTP service. Attacker sends an NTP monlist Request to the server, but its source IP address is not its own IP address, but the IP address of the target. After the server receives the request, it will send a Response message to Target (not Attacker). Since Reponse contains 600 time synchronization records with Server, which is much larger than Request and consists of many messages, amplification is realized.Among the "waking up" experiencers, Ellie actually experienced a knock at the door by death because of a "failure" and never dared to talk about "suicide" again.　　当时的嬴政（林峰 饰）还没有登上帝位，更被囚禁于赵国。少龙为了能返回未来，便不惜一切帮助嬴政顺利登上帝位。由于少龙的机智过人与特殊身份，他的能力得到了众人的赏识，因此他也遭到了多方奸狡之人的暗算。(3) Verification of js event blistering
