In the last row of the computer room, on the monitor in front of Chen Yan, a waterfall of information and data was quickly brushed through.

Although Elon was puzzled by the inexplicable news sent by Chen Yan, he finally responded, not to mention that Chen Yan was his boss, at least Chen Yan's achievements in AI still made him admire.

Within a few minutes, the computers in the entire computer room had been controlled by Elon.

And all the gateways on the campus along the road have also been taken down, because they must be taken down before they can control the computers in the computer room.

It's like a huge river with countless branches underneath, and the river must first pass through the main channel, and then it can flow to the branch channels, and the gateways are the confluence of the main trunks and branches of these rivers.

Bai Yujing is a junior in the Academy of Planning, on a whim, he developed a beauty list, and later his schoolwork was heavier, and he had already successfully obtained an offer from an IT company, so he didn't care much about the operation of the beauty list, and when he knew about this emergency, it had been almost an hour.

When he tried to connect to a "server" hosted in another computer room, he found that he had lost control.

The server that runs the beauty list is not a real server, but an extremely ordinary civilian PC with linux installed.

In addition, it is not accurate to say that the hosting is not accurate, because only the power supply and network of the microcomputer room are used, and some network equipment in the normal data center, such as "access layer switch", "aggregation layer switch", "core layer switch", "Internet behavior management", "firewall" and so on, there is only one "router" that integrates all these functions In fact, on the contrary, everything will be equivalent to nothing, and if it cannot prevent the spread of illegal information, it will be easier to be attacked.

When someone noticed that the beauty list site at this time was a little stuck, the server of the beauty list changed hands again.

Elon easily took control of the beauty list.

Just as Elon was preparing to recover the website's data, a tricky thing arose.

First of all, there is no scheduled backup function in this broken host, and there is no option to restore from the backup data.

The second is that there is no backup of any static files in the host of the beauty list.,All the picture files before they were modified,No longer exists.,The "jack_JOW" of the County Institute of Technology actually used the method of secure erase of the disk.,The original picture becomes unrecoverable.。

Under normal circumstances, in the Linux environment, files deleted from the computer using the delete key, emptying the trash or rm command are not permanently and safely deleted from the computer's hard disk (HDD or SSD), but only hide the target file from the user, in fact, it still resides somewhere on the hard disk and may still be read. The method of secure erasure is to repeatedly write data and delete files in the way of file overwriting to the location of hidden files, so that the area becomes chaotic, so that the disk in the target area loses the initial data information.

For example, if you write on a blank piece of paper with a pencil, you think that after erasing it with an eraser, others will not be able to see it, but when you write with a pencil, it will leave traces, and you can see the original handwriting by looking sideways or lightly smearing a layer of pencil ash on the writing position, so as to distinguish what words are written. However, if you write repeatedly in the same area, it is difficult to tell what is written, even if you put a gray mark on it.

In desperation, Elon had to send a message to Chen Yan and needed to get the original file of the picture from the website developer.

I don't know if the developer has that data.

Chen Yan didn't know who the developer was, so he hurriedly asked in the dormitory group.

Wang Dang heard the prompt sound of receiving a message on his mobile phone, took it out and looked at it, and found that it was Chen Yan of the dormitory group who said that he wanted the original data, and immediately wondered, what do you want the original data for?

"Brother Gaoren, have you regained the authority of the website?"

After Qin Xiaochuan reacted, he asked.

"Cowhide!

Ni Yixiong also immediately offered his fart.

"Wait for me, I'm in a group of Senior Brother Bai, I'll go find him. ”

Wang Dang suddenly woke up at this time and immediately went to Bai Yujing to ask for picture files.

Not long after, Wang Dang sent a data packet to the dormitory group.

After Chen Yan forwarded it to Elon, it took less than three minutes for the website to return to normal.

"Okay, okay, the beauty list is back to normal. ”

"Senior Brother Bai Niu Cha @ Bai Yujing is a little white dragon. ”

"Hunan big cowhide!

"Let's go, the county Polytechnic BBS has a wave. ”

"them!"

"The crack in the wall suggested hacking their bbs, let them know who is the first brother of Junsha. ”

"Senior Brother Bai them and takes down their BBS!"

The moment he saw the beauty list return to normal, all kinds of news were flooded in various groups, but when Bai Yujing saw that someone said that he was going to hack the BBS of the County Institute of Technology, he sighed helplessly and sent a message.

"The beauty list is not something I recovered, and I am not good at the offense and defense of network security. ”

"I don't have the ability to regain control (눈_눈), and I was going to close the beauty list directly, and then go online when it returns to normal. ”

"It was Wang Dang from Class 3 of Level 20 who came to me and said that he had taken it, but the picture data was safely deleted and could not be recovered, so the original data was needed. ”

"So you said you were going to hack the BBS of the County Institute of Technology,-,- I can't do it!"

Bai Yujing's words made the group a little fryer, and they all wondered which animal Wang Dang was, he was so violent, he couldn't handle the things that Senior Brother Bai couldn't handle after getting an offer in his junior year, when did the junior brothers in his freshman year become so tough?

Wang Dang looked at the chat messages in the group, broke out in a cold sweat, and hurriedly explained.

"It's not me, I'm just a stinky brother!"

"A brother in our dormitory, an exchange student from Stockholm University this year. ”

Wang Dang did not directly reveal Chen Yan's name, but some people in the group started a crazy discussion on this topic, and all of them were women.

"I know I know, that guy is super handsome, super temperamental, I've seen it twice. ”

"I heard that he can speak seven Chinese, oh, so powerful, I didn't expect the technology to be so good." ().̮)✽) Oops, it's the feeling of being in love. ”

I have also seen him from afar, and I heard that his name is Chen Yan, but I don't know if he has a girlfriend. ”

"Ever since I met him, why have I been so rare with other boys?"

"You guys are going to die of this heart, he has long been taken down by so-and-so, and so-and-so is said to be a teacher. ”

"I'm throwing a special meow Lou, what's the hurry?ʕ⊙⊙ʔ"
