Chapter 63: The First Battle

Sun Dongyang followed the sniffing program and chased after him, but the target was also very cunning, and the host it retreated from was just a meat machine. Sun Dongyang is so sure because he knows the address. That's the server of the post office in S city. Sun Dongyang's classmate and friend worked there as a safety director. His classmate is also a talent with very good computer skills, and often discusses offensive and defensive knowledge of computer security with Sun Dongyang. I didn't expect to be made a meat machine this time, and I didn't know it. Sun Dongyang is ready to laugh at his old classmate the next time he sees him.

However, at this time, Sun Dongyang did not have time to greet his old classmates. He was engrossed in his gaze, not letting his target escape. The target has successively passed through three meat machines as a springboard, namely the host server of the S City Telecommunications Bureau, the host server of the S City Insurance Company and the commercial host server of a large enterprise. This surprised Sun Dongyang, this goal is not simple, just from the perspective of these servers he captured, they are all in an important department in S City. Problems with any server can cause big trouble. And the more important the computer, the more advanced the security policy of the server itself. The target is able to obtain super administrator privileges without the double check of the hardware firewall and security personnel, and its hacking level should be quite high. Sun Dongyang had the excitement of meeting a master. Only by playing with the master and defeating it can Sun Dongyang have a sense of achievement. Dealing with rookie hackers who can only use vulnerability scanning software all day long makes Sun Dongyang feel bored.

Finally, after the target retreated to the fifth address, Sun Dongyang did not know if this was the target's lair or was still a broiler, and because the target knew that he could not get rid of his tracking, he began to organize defenses on the spot. But anyway, the real confrontation between the two finally began.

The target's defense system is well-established. All of the vulnerabilities in Knowing have been patched. Firewalls are also not a common product on the market. Sun Dongyang's invasion was hampered here. But Sun Dongyang was not discouraged, but even more excited. He knew that this place, if not the computer next to the target, was a very important fortress computer for the target. As long as you capture this place, you will not be far from capturing the target. What's the point of beating down an opponent all at once. The more challenging the task, the more fun it is. Sun Dongyang continued to attack along the route he had just tracked, sneering and muttering to himself, "Finally stopped running?" Then let me try your pounds. "On the one hand, another line of attack was drawn from the headquarters of the National Security Agency, and the IP address of the target in a straight line.

Sun Dongyang is trying to overwhelm people with power. The computer in the headquarters of the National Security Bureau where he works can be one of the best in the entire city of S. This is not comparable to the average home computer, and the cabinet with the CPU alone takes up an entire room. It is a real mainframe. And when needed, it can also be combined with several mainframe computers in the university town of S City to form a supercomputer system. In terms of the amount of computing alone, it is not much more than the most advanced supercomputers in China. Those supercomputers are more advanced than the supercomputer network system in S City, but they are smaller in size and lower in maintenance costs under the premise of the same amount of computation.

Of course, Sun Dongyang will not use the supercomputer system lightly. Because the mainframes in those universities are also full of computing tasks. And Sun Dongyang believes that relying only on the mainframe of the National Security Bureau itself is enough to crush ordinary hackers.

Sun Dongyang's soldiers divided into two ways, all the way along the tracked route to find the loopholes in the target's defense system, constantly disguised as various legitimate information in an attempt to deceive the interception of the firewall. The other way is to directly use the huge amount of data through brute force attacks to let the opponent's data overflow and collapse the opponent's defenses, which is equivalent to facing a city. Sun Dongyang was the attacking side. On the one hand, a small force was sent to sneak under the city gate to pick the lock, and on the other hand, the siege force was sent to smash the wall with trebuchet. Either side succeeds and allows him to storm the city without any problems. And as a defensive aspect, defending against two very different attacks will definitely take care of one or the other. This ultimately led to a total collapse of the defense.

Sun Dongyang thought very well, but what he didn't expect was that the hacker he regarded as highly skilled and cunning was actually just an intelligent program designed by Song Baobao. When Sun Dongyang began to attack the firewall on Song Baobao's computer, Song Baobao also received feedback from the sniffing program and began to officially take over the defense.

Sun Dongyang's attack was less than two minutes away, and the data flow of the first attack was suddenly eliminated by a counterattack from the opponent, and the opponent directly pushed the defense line forward to the previous meat machine. One by one, the server meat machines of insurance companies, telecommunications companies, and postal companies were taken over by the other side and organized for defense. The advance of the battle line was no slower than it had been when it had retreated. Sun Dongyang was repelled by Song Baobao's attack with almost no decent attack on this line, and was regained by Song Baobao.

But Sun Dongyang didn't care. Just now he was just focusing on tracking the target, and he didn't set up defenses on the machines along the way. These machines have been invaded by targets for a long time, so naturally they know better than themselves. It is not surprising that it was repulsed. And Sun Dongyang has already found the main fortress computer of the target. The massive data stream attacks sent directly from the NSA are his main direction of attack.

Therefore, Sun Dongyang did not entangle too much with the opponent on the first line, and directly gave up the attack on the first line. Focus on the second line. But at this time, when Sun Dongyang carried a huge data stream through the router to attack the target. Suddenly, the target vanished. To put it in martial arts terms, it's like punching with all your strength but hitting the air, and if you don't do it, you will get internal injuries. Although Sun Dongyang was not injured internally, he was also stunned when he looked at the screen.

"Is the other party physically disconnected?" Sun Dongyang chattered suspiciously. It is important to know that although a physical disconnection can immediately cut off the network connection, it will still leave a large number of clues in the network. And once the network is physically disconnected, it is equivalent to handing over the decision of the entire network to the opponent. It's like running away on the battlefield, and the losses are likely to be even greater. Therefore, between hacker attack and defense, unless it is absolutely necessary, they will choose to physically disconnect the network. And the target is under Sun Dongyang's attack, and the defense is not leaky, obviously there is still room for support, why did you choose to physically disconnect the network?

Sun Dongyang's guessing and analysis didn't last long, just a few seconds after he confirmed that the other party had been physically disconnected, a shrill alarm suddenly sounded in the entire computer room. The NSA's firewall was suddenly hit by a large number of cyberattacks from unknown sources.
