data repair

While the boss was eloquently educating Jin Yuxing on hacking knowledge in bedroom 303, the heads of the computer and intelligence circles of several major countries gathered together immediately.

Compared with the attack on 02 root servers around the world in 13, the complete scrapping of the auxiliary root servers of the Internet Software Consortium this time worries those who know the details even more.

After all, it was just a ddos ​​attack in 02.At that time, 30 to 40 times more data packets than the normal number hit these root servers violently and caused 9 of them to fail to operate normally.

However, this is nothing more than a crash, there is nothing wrong with the root servers themselves.

For example, it's like a group of people blocking the door of your house, people outside can't get in, and people in your family can't get out. This is the so-called ddos ​​attack, but there is no loss of anything in your house.

If the ddos ​​attack only attacks the general website server, then the entire Internet will not be paralyzed.It happened that in 02, root servers around the world encountered a 'blocking' incident at the same time, so it led to serious consequences.

Of course, there are many theories about who was behind the 'blocking the door' incident in 02, and no one can fully understand it.However, the events that happened in front of them made the elites of the great powers panic.

Vulnerabilities of giant servers definitely exist, and this problem is unavoidable on every root server or even a web server.In contrast, the security policies on these servers are more impregnable than personal PCs.But under such circumstances, the auxiliary root server of the 'Internet Software Consortium' was still directly scrapped in just a dozen seconds, such hacking methods are daunting.

Originally, the IP segment attacking the campus network of Peking University was not limited to "an IT company in San Francisco", but when all the machines of this company were scrapped, the rest of the collaborators immediately received the wind, and quickly stopped the work at hand with lingering fear. The far east retreated back.Then, these people were stunned to receive news that the 'Internet Software Alliance' had also been attacked.

CIA building, a small meeting room on a certain floor.

"Director, the general investigation report of this incident has been passed over there!" The secretary of the director said, "The specific server test report has to wait for the final judgment of the 'Internet Software Consortium'!"

"Oh!? What did the report say?" CIA director Peter Pan asked.

"The report said that this incident may be related to our organization's cyber operations! Maybe it's the East's counterattack!" The secretary repeated the views in the report.

The leader of the network intelligence team, Yin Si, yelled angrily, "This is impossible! The network technology of the East is a piece of shit in our eyes!"

"Ince, don't forget that our bureau's activities have been done step by step recently, but there are no big moves. Only your attack on the east side is the most likely to lead to the opponent's counterattack!" Yin Enzhen, the leader of the Asian intelligence team, said.

"You..." Ince was obviously unwilling to take the blame for this, and was about to retort, but who knew that it was Pan Peter who slapped the table and shouted: "Enough!"

A meal in the conference room.

Pan Peter said again: "Let's put aside whose responsibility we don't discuss, and talk about your views on this hacker attack?"

"I think……"

At the same time, in country y, in rb, in country e, and even China... similar meetings are going on.

……

At the moment, Simmons, chief engineer of the Internet Software Consortium, is crossing his arms and watching his staff check the root server.

The inspection results came out quickly, and all the hard disks on the hard disk array were damaged, and none of them were usable.But there are not many bad sectors on each hard disk, just like we usually format the hard disk, as long as we format a little, we can repartition.

The most critical point is that after the backup hard disk array is connected, the entire server cannot be restarted even if it is connected to the power supply.

Such results are undoubtedly shocking.

If in the past, someone said that someone could hack and destroy a giant server through the Internet in a few seconds or even less, the elites of the 'Internet Software Alliance' would never believe it.But now, living examples are before their eyes, and they have to admit that this is a slap in the face, and they were slapped in the face naked.

The CEO Rhodes also brought a large number of his elites to watch the inspection process of the 'Software Alliance' through video, and everyone realized the terror of the person who carried out this hacker attack.This is by no means a problem with the security policy on the root server, because the other party didn't touch those things at all.Otherwise, once you get entangled in the security strategy, the battle will never be over in just a dozen seconds.

The engineers of the 'Software Alliance' began to remove the bad hard drives on the array and check them piece by piece on other computers.

Soon, Hahn, an engineer in front of a computer, exclaimed as if he had seen heaven and man: "This hacker is really powerful!" Everyone's attention was immediately attracted.They all knew that Hahn had done a lot of research on hardware, so it was no surprise that he could find the reason.

"What's going on? Hahn, why do you say the hacker is a person?" A computer elite asked.

"It's very simple. I tested three hard drives in a row and found that most of the information on tracks 1 to 8 was erased at the same time, causing the hard drives to be damaged..." Hahn said with a serious face, "I think other Probably the same with hard drives, do you know what that means?"

"At the same time? Is there no difference in milliseconds?" Someone asked.

"That's right... a millisecond is not bad..." Hahn said, "This can only be done by one person, otherwise, even a well-coordinated team will cause a slight time difference when the command program attacks the hard disk of the server due to hand speed problems! "

"But it can't be concluded that it was done by one person?" A beautiful engineer retorted, "You know, in order to reduce the burden on the server, our hard drives don't support vertical reading and writing!"

The so-called vertical reading and writing refers to intelligent seeking and intelligent reading and writing.On ordinary personal PCs, this technology is widely used, because no matter how personal PCs read and write, its data volume rarely exceeds 1TB, and the overall burden on the computer is not large.However, for root servers with huge daily data traffic, this is a huge burden.

"You said this just confirms my non-team statement!" Hahn continued his point of view, "You know, even hard disks produced by the same manufacturer, the same model, and the same batch have slight differences in the speed of the hard disk. This is even more so, plus the problem of everyone's hand speed, then what team can kill so many hard drives at the same time in such a unified way?"

The beautiful engineer refused to accept: "If the other party is only one person, then tell me, how did he do all this?"

Hearing this, not only Hahn laughed, but also the colleagues beside him.

Simmons, who was always stern at the side, said: "If Hahn knew, he would become a 'God'!"

This made the beautiful engineer quite embarrassed.

"Okay, stop laughing! Didn't you say that besides the hard disk, there are other problems with the server?" Rhode said on the screen, "Then check it quickly! The cia is still waiting for our report! "

……

"What!? Boss, you mean, not only our campus network card, but also the campus network in Shencheng and Wucheng?" Yuxing said in surprise.

"That's right! If you don't believe me, you can go to 'Tianya' to have a look and you'll know! There's already a ruckus up there!" Zhang Yi said.

"What about Mizuki next door, and HKUST?" Yu Xing asked again.

"It's all stuck!" Cao Donglin answered, "We're all dead here, so we can lose them!"

Yu Xing fell silent immediately, it seemed that he was a little reckless in this shot.Maybe he was a little dizzy when he saw the beautiful woman Han!But fortunately, this time the attack on Yu Xing was not completely reckless, otherwise there would be a bigger disturbance.

Right now, Yu Xing decides to be a man with his tail between his legs, otherwise he will be in trouble if someone notices him.

Unfortunately, what Yu Xing didn't know was that he was already being targeted.

The next day happened to be Sunday, so Yu Xing got up early for morning exercises.Now he can't even think about the equipment of the Taekwondo club. Ever since Pu Jinxi collapsed in public, he has been regarded as a wolf by the members of the Taekwondo club.

Therefore, Yu Xing can only run around with a heavy load, and then go to the forest to practice boxing to achieve his goal. Although there is little progress, it is better than nothing.

As usual, Yuxing ran around the Weiming Lake for a dozen laps, and was about to get into the woods, but he didn't expect a familiar figure to appear on the path ahead.

Han Yingqiu!

Yu Xing muttered in his heart, and turned into the forest path without seeing it.

Unexpectedly, Han Yingqiu also followed.

After running for a while, seeing that the other party was still following, Yu Xing finally couldn't help but stop, and didn't talk to Han Yingqiu, and practiced Wen Qu Ziquan in the middle of a small open field.

Unexpectedly, Han Yingqiu followed suit, stopped, took out a small cloth mat from the sports bag behind her, spread it on the floor, and practiced yoga.

After being teased by her like this, Yu Xing almost lost his temper.Fortunately, the forest was quiet at this time, and the dense air was lingering. Feeling the surrounding atmosphere, Yu Xing finally calmed down and completely merged into boxing.

The brilliance of the morning sun sprinkled through the dense forest. At this time, Yu Xing's boxing skills were fully unfolded, his eyes were piercing, his energy and spirit reached the peak of fullness, and his mental power even dispersed into his limbs unconsciously. , and slowly circulate in the meridians.

Beside, Han Yingqiu, who was expecting Yuxing to strike up a conversation, couldn't help being shocked.

I saw Yuxing's boxing circles around, like a dragon going out to sea, and like a phoenix singing from the sky.At the boxing place, there is the sound of dragons roaring and tigers roaring, the power is astonishing.As the footsteps unfolded, his body was like a dream, erratic, and the field was full of afterimages, and his fists merged into one, and there was no distinction between them!

(I am afraid that the second watch will be at 01:30 in the morning, and I will confess!)
