Chapter 281 Administrator Account

Sun Chao found that there were already three administrator accounts. After following the clues, Sun Chao finally figured out that one of the three accounts was the account of the principal Wei Yang, one was the dean of the computer school, and the other was the head of the computer department. .

Sun Chao originally intended to directly take over the principal Wei Yang's account, but he gave up. Although he heard that the principal was a computer novice, he didn't know if it was true or not.

To be on the safe side, Sun Chao planned to use the loophole to recreate an administrator account for himself.

And it can't be put on the bright side. When Sun Chao plans to create it, he will hide it by the way.

There is no shortage of experts in Sun Chao's school. If someone is found out that he has taken over the principal's account, he needs to trouble him a second time, so it's better to solve it once.

The advantage of creating a hidden account is that next time you can enter the server openly and save trouble.

It would be a waste of time if you need to hack in every time.

Sun Chao has always known that he is a person who is afraid of trouble, and would rather waste some time at the beginning than go through such trouble every time.

Sun Chao is still very self-aware.

After creating the account, Sun Chao successfully entered the school server.

Sun Chao planned to use this server as a springboard to attack the firewall he had just finished, to see how the masterpiece he had just completed was.

Sun Chao planned to test the effect of the firewall he made first.

Then patch the two vulnerabilities I found on the server, and install a few honeypots by the way.

Sun Chao plans to make the school's server more perfect.

But it can't be seen by administrators and computer novices, which will take a little effort.

From now on, it will be my own territory, how can my own home let people come and go as soon as they come, right?

After Sun Chao was ready, he launched an attack on his desktop computer.

Although the computer can't be compared with the server, the Taishan Firewall established by himself has initially resisted Sun Chao's attack.

"not bad."

Sun Chao was still satisfied.

There are usually two ways to implement the attack: one is to use system vulnerabilities or defects to send illegal data packets to the target system, causing the target system to crash or restart;
The second is to use denial-of-service attack tools to send a large number of data packets to the target host, consuming network bandwidth resources and host resources, causing the network or system to overload and stop providing services to users.

Currently, the most influential and harmful is the distributed DoS attack.It controls a large number of network hosts to launch an attack on a certain target at the same time, which can easily cause the system of the attacked host to be paralyzed, and due to the large number of hosts participating in the attack, it is difficult to locate the source of the attack.

Sun Chao intends to try both methods to see how his firewall is doing.

Sun Chao found that the firewall had been blocking his attack, and the memory overflow information was directly repaired by the firewall.

Sun Chao is still very satisfied with the result, this firewall has initially passed the test.

Sun Chao plans to visit the hacker website often in the future, so he can't keep working behind closed doors.

After the end, Sun Chao looked around in the posts on the campus network, but he still didn't see the list of players for this competition.

Sun Chao didn't know if it wasn't the time for the announcement, or what, but the list of players who participated in the competition has not been announced yet.

Sun Chao also intends to see how many teams participated this time, and also to know how the skills of the participants are.

Since there was no Sun Chao, he withdrew directly.

While Sun Chao was messing with the school server, the school management was also having a meeting.

The theme of this meeting is to determine the participating teams.

Under normal circumstances, as long as they are juniors and seniors, as long as they sign up, they can see it without such trouble, but the reason why it has not been announced is Sun Chao, a freshman team.

Because whether or not to report this team to the competition, there has been no agreement.

One side of the opinion is that they are afraid that the freshman's skills are too poor, and they will be brushed off directly if they go up, which will embarrass Peking University.

The other party thinks that Sun Chao's ability is very good, even if they are brushed down, they can let them practice for a while, as if they are accumulating experience.

Sun Chao is still a very good student, what if there are any surprises.

And another member of the competition is Fan Kexin, the son of Fan Yong. Although this kid is only a freshman, because his father is an expert in this field, this kid has been exposed to computers for a long time.

This is the main reason why the teachers on this side agreed to their participation.

One is the best student in recent years, and the other is a child who has been exposed to computers for many years.

The atmosphere in the conference room was quite tense.

"I don't agree with freshman students participating. If they are rejected as soon as they go up, then we will lose face at Peking University."

"Those who don't know think that our Peking University students are all at this level. Isn't this a shame." The few female teachers in the conference room said very dissatisfied.

The teacher of the computer department next to him was unwilling: "Is there a rule in our school that freshmen cannot participate in this competition? Did the organizer say that freshman students cannot participate?"

The teacher next to him who didn't want Sun Chao and the three of them to participate in the competition was indeed speechless. Indeed, neither the school nor the organizer said no, and they couldn't open their eyes and talk nonsense.

"Since there is no clear rule that freshman students cannot participate, why don't you let other students participate? How many of their children want to participate, that is self-confidence in their own skills, and we should encourage them."

The female teacher still disagreed, and then said: "Do you see freshman students participating in other schools? Everyone doesn't know that it is impossible to get grades and it will only hurt students' self-confidence. I am not against it. They participated, but let them study in school for a few years, so that they have a better chance of winning."

"Anyway, I have confidence in the three of them, and they are the best students in our school in the past few years; and Fan Kexin in this team is not an ordinary student, you may not know who it is, but you must know who his father is .”

The teacher did not wait for others to ask and continued: "Fan Kexin, the son of Fan Yong, the dean of the Computer Research Institute; as far as I know, this Fan Kexin started to use computers when he was in junior high school. How could his computer skills be comparable to that of ordinary first-year students."

At this time, Fan Kexin's counselor came in.

Seeing that everyone was discussing, Fan Kexin's counselor found a seat nearby and sat down. Before he came, he guessed the reason for coming.

Although the female teacher's attitude was a little loose after hearing what the teacher said, she still asked: "If Fan Kexin's skills are really good as you said, why did he rank in the top ten in the class in the last few exams?" A few, I knew this in advance."
