Strange, obviously just found a loophole, and it disappeared in a blink of an eye.
Teachers and students from the computer departments of major universities participated in the actual combat test, and there are all kinds of beings.
The attack lasted for a total of three hours before Chen Nuorang stopped the attack.
Eagles, stats.
Yes!
Others in the meeting room also stared at the eagle, waiting for the actual measurement results.
After waiting for nearly 1 minute, the eagle opened his mouth and said: 96 billion attacks were attacked and resisted within three hours, with an average of 32 billion attacks per hour, the highest computing power reached 2.8PFlops, the average computing power was 1.9, and the system computing power load was 280%.
What?How is that possible?
Shen Nan exclaimed.
Ari receives as many as 3 million attacks every day, and the highest number on Double Eleven is only 22 billion. The attacks by teachers and students in 151 colleges and universities are even more powerful than hacker attacks.
They have all seen the actual combat plan. The computing power of the Xuanwu system is limited to 1PFlops. It is a fantasy to block the attack with the highest computing power of 1PFlops with 2.8PFlops computing power.
Data don't lie.Chen Nuo said something indifferently, and then said: "Report system problems."
A total of 12 vulnerabilities occurred, including 0 A-level vulnerabilities, 2 B-level vulnerabilities, and 10 C-level vulnerabilities. The system has all been repaired by itself.
Vulnerabilities are divided into three levels, A, B, and C, from high to low according to the degree of danger to the target host.
A level is that it is a vulnerability that allows a malicious intruder to gain access and potentially compromise the entire target system.
Class B is a vulnerability that allows local users to elevate their access privileges and potentially allow them to gain control of the system.
Class C is any vulnerability that allows a user to interrupt, degrade, or impede system operation, such as a 404 code.
I am!
Shen Nan swears again, and the others look puzzled, unable to understand the meaning of this data.
9 holes?so much?
Boy, your system is not working, there are so many loopholes.
Why are you so surprised, please explain quickly.
Lei Ling gave Shen Nan a hard look, and Shen Nan said: Leaders, there are really not many loopholes. Let me put it this way, some large companies have relatively long business lines, so they often encounter weak passwords. Tens of hundreds of loopholes.
There are many types of vulnerabilities, such as DOM-type XSS vulnerabilities, storage-type XSS, reflection-type XSS, relatively hidden sql injection, SVN leaks, etc., and some companies cannot discover it themselves.
The logical complexity of the Xuanwu system is top-notch in China, and the country's ticket booking websites can barely compete with it.
With Shen Nan's explanation, everyone understood, and their eyes were full of shock.
Especially Mr. Chu and Mr. Wang, who participated in the development of the algorithm for the development of the booking website back then, naturally knew how complicated the website was.
Xuanwu has such a huge system, but there are only 9 loopholes, which can be ignored. This is so fucking awesome. I have to say that this group of masters is awesome.
Chen Nuo, quickly test the second part.
Are you ready for money?
Why are you preparing money?
Once the system activates the counterattack mechanism, it will automatically track and counterattack the intruder, and the hard disk of the other party's computer may be damaged. Based on the computing power of the attack just now, the average selling price of these students' computers is above 8000.
If 8000 units are damaged, that is [-] million. Will you or I pay the money, or the Ministry of Education?Or is it the student's responsibility?
Minister Chen, we pay the money, how about you take care of the aftermath?
Lei Ling is very straightforward, in his opinion, it is too cost-effective to test this system with 8000 million.
Chen Bo nodded, there was no reason not to agree.
Minister Chen, the test will start in 10 minutes, please let me know!
The countdown began, and this time the eagle and the knight were more nervous. Passive defense and active tracking and attack are two different things.
The countdown ended, and the big screen code jumped again.
After 1 second, a red code block suddenly appeared on the big screen and began to flash.
At the same time, harsh sirens and mechanical voices sounded in the conference room and hall.
Warning, detection of intrusion, activation of defense mechanism.
When C-level attacks are discovered, active tracking and anti-attack mechanisms are activated.
Start the cooling system of the equipment room.
After a series of mechanically synthesized sounds sounded, the next moment, the code on the entire big screen went crazy, and the flow speed could not be seen clearly.
The server on the second floor began to roar, and waves of heat came from the computer room.
I'm going, someone is attacking me, come and support me!
Fuck, didn't you mean just participate in the attack?Didn't you say it was offense and defense?
Damn, my computer, my teacher Cang
The computer was killed, who is responsible for this?
All the teachers and students who participated in the attack found that their computers were out of their control.
Some computers even died after emitting a burnt smell.
Without waiting for the teachers and students to make a fuss, the higher-ups notified directly that all the computers that died in battle would be equipped with a new one according to the original configuration, or compensated at the original price.
This decision instantly detonated all the teachers and students.
Those who were killed were extremely excited, those who were not killed wailed, and of course there were also some wailed for being killed, calling out Teacher Cang
This time the test lasted only a few minutes before it was over.
Report the results!
This time a total of 3 million times, 10189 people participated in the attack, scanning the hard disk data of the intruder, the intrusion response time was 1 second, the computing power was used 1.6PFlops, 2 servers were started, and the energy consumption was 1000 kWh.
A total of 4899 intruder computers were damaged by counter-attacks.
After Eagle finished speaking, several information packages popped up on the big screen.
Mr. Shen, the data packet No. 1 is the IP address of the teachers and students who participated in the attack.
Packet No. 2 is the serial number and configuration of the damaged computer.
Shen Nan is overjoyed, if this system is used in the future, if someone attacks the website and obtains the IP, then the intruder will basically be caught one by one.
If you dare to invade, I will arrest you all and work for me.
Don't get too excited, this time it went so smoothly because the teachers and students are rookies, and experts like Eagle, the possibility of this system catching them is only 50%, and the project team members should be around 70%.
Chen Nuo looked at the excited Shen Nan, poured a basin of cold water, and continued: Of course, if you can improve the current configuration to another level, the eagle can also become a chicken, and the knight can also be ridden by others.
The faces of the eagle and the knight instantly darkened.
Chapter 118 Are You a Jingle Cat?
Overall, the test
Wait a moment.
Chen Nuo was interrupted by Shen Nan before he finished speaking.
You only mentioned 3 of the 2 file packages above, what is the 3rd one?You didn't copy the other party's information, did you?
As soon as Shen Nan said these words, Chen Bo sat up straight.
Copying the other party's information can be big or small, and it is a violation of privacy if it is big.
See for yourself!
Chen Nuo typed a few times on the computer, then pushed the computer to Shen Nan.
After Shen Nan opened it and looked at it for a while, his face became strange. The data package is a statistical file, which is the name and memory size of the data in the intruder's computer. The system has already classified them.
What happened to Shen Nan?
You'd better let Chen Nuo talk!
Everyone looked at Chen Nuo. Chen Nuo smiled and said, "Let me make it clear. It contains the name of the computer data that the system scans for intruders. The first place is the small movie, with a total of 4800G memory and more than 20000 copies."
Pfft!
Haha
cough cough cough
Shen Nan, Eagle, and Knight couldn't bear it any longer, and laughed wildly.
Mr. Chu, Mr. Wang, and Lei Ling looked dumbfounded. How normal is it to watch a movie? Why is it so funny?
Chen Bo and Wu Yuanming's faces turned red, and the veins on their foreheads were throbbing.
Minister Chen, how normal is this, they are all young people, you don't have to be so conservative!
Chen Bo glared at Chen Nuo fiercely. He found that this kid always played cards out of routine.
Under Lei Ling's staring eyes, Shen Nan explained in a low voice, the whole meeting room was completely out of control.
After a long time, Shen Nan asked: Chen Nuo, since you can scan the name of the other party's profile, you should also be able to copy the profile of the other party.
If this can be done, the entire Xia Kingdom Online will no longer be a place outside the law.
Yes, but pointless.Copying the other party's data requires the other party's network speed and the other party's reading speed. A file is hundreds of megabytes, which will inevitably consume the other party's computer calculations. Do you think the other party can't detect it?
After Chen Nuo finished speaking, he paused, and continued: Besides, if the other party dares to invade you, do you think they would be so stupid as to save confidential files in the computer?
Shen Nan smiled awkwardly, he forgot such a simple truth in a hurry.
Overall, this test works well, we still need to optimize it, and deliver it to you after the second test.
Mr. Shen, you need to be prepared for the test on the 15th. We need to use master hackers and servers with more than 1PFlops or supercomputing attacks. Only such masters and centralized mobilization of computing power can test the ultimate pressure of the system.
OK, we'll get ready!
Although today’s attack intensity is also very high, they are all computing power generated by computers connected in parallel, which is relatively scattered. Under the control of hackers, super-computing attacks are based on point-to-point attacks. The same 1PFlops computing power produces very different effects. .
After everyone chatted for a while, Chen Nuo said: Mr. Chu, Mr. Wang, dinner will be in an hour, how about we have a celebration tonight?To tell you the truth, I'm a good cook, boy, do you want to show off to you guys?
Chu Xiutong and Wang Shicheng couldn't laugh or cry.
Is your boy Tinker Bell?How can everything?
I think it's okay, Chen Nuo is going to get some food, let's take advantage of this time to do a secret procedure, what do the two elders think?
Row!
Well, I was delayed for a day, and it's not too late!
After Chen Nuo explained to the eagle, he went to the first floor.
The bosses have signed countless confidentiality agreements, and there is no need to publicize them, just sign a document, and it will be done in a few minutes.
Minister Lei, according to your NSA's investigation and analysis, how is Chen Nuo doing?
Seeing that Mr. Chu had spoken, Lei Ling glanced at Shen Nan, and Shen Nan said: "This kid is a narrow-minded master, he is extremely protective, if you provoke him, he will definitely return it, but this kid's character is really nothing to say, he is extremely patriotic." .
He is not in a hurry to do things, what should be done and what should not be done. He is very clear and has his own opinions. He is typical of being soft and not hard. Yes, he doesn't have to, but we can't deny it, and this kid likes freedom very much, and doesn't like others to interfere with his decisions.
I don't know about his other aspects, but in terms of programming, in time, it will be the most important weapon in the country.
Shen Nan's last words shocked everyone, they did not expect the NSA to give such a high evaluation.
Mr. Chu, our professor of psychology and behavior in Huaqing came to the same conclusion as Mr. Shen.
Wu Yuanming also replied.
Mr. Chu, Mr. Wang, and Chen Bo were silent, and they didn't know what they were thinking.
The silence in the conference room was broken by Eagle calling everyone to go down for dinner.
When everyone reached the first floor, Chen Nuo came out with a chef's hat and a plate of dishes.
Chen Bo was stunned. This kid really looked good. There were eight dishes on a table, not to mention the taste, but they were all delicious.
Sit down and taste my craft.
Several people sat down and took a sip.
