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.Now, although the practice is over, the words of "industry serving the country" and "down-to-earth" are deeply imprinted in the hearts of the team members. "I hope you can be intelligent" low entropy "people, because in this way you will be richer and become more useful to the society in the future!" It is precisely because of Mr. Sun Yimin's hard guidance and accompanying team members that they can have a broader vision and more confidence in the future.16.8 Chronic progressive diseases of throat that affect function and are not easy to correct are unqualified.Composite Reuse Principle (CRP) is to use some existing objects in a new object to make it part of the new object. New objects reuse used functions by delegating to these objects. In short, it is necessary to use synthesis/aggregation as much as possible and not inheritance as much as possible.The last such leak shocked the US National Security Agency in 2013, when Edward Snowden released confidential information about the agency's surveillance activities. But as experts pointed out, the information stolen by shadow brokers is more destructive. As the New York Times analogies, if Snowden announces an effective battle plan, the shadow broker will release his weapons on his own.
