Security executives are never willing to talk about these attacks because they do not want their remarks to attract more attention to the enterprise. They even worry that providing basic information on defense strategies alone will be enough to attract attackers to come and find security vulnerabilities.十四天第一季……德布拉甘萨从没有小视过这个没见过面的敌人。蒲俊冷笑道：想死？没那么容易。TCP FloodWe know that in x64, the first six parameters of the function are stored in RDI, RSI, RDX, RCX, R8 and R9 registers in turn. 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.
