We 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.僕だって泣いちゃうよ -- NMB48悠扬清冷的箫声回荡在天地间，将玄武王心情表现得淋漓尽致，那是尘埃落定的淡然，那是喧嚣过后的沉淀，那是勘破人生的从容，那是含着微笑的等待。1. The role of the Sentinel process: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.故事以平凡小胖子乐乐的校园生活为背景，讲述钢铁飞龙——炽焰、深蓝、铁拳、Maggie、小星五位战士从未来世界穿越而来，在指导、带领乐乐在一次次击败怪兽的过程中，陪伴他成长为未来英雄的故事。全片除了有热血和冒险元素外，还会有小主角历险后的感悟，让孩子在英雄身上学会成长。RF Front End Design Challenges
