The next day was Saturday, Hu Yifei came to Weilan in the morning, and as soon as he entered the office, before he could catch his breath, Section Chief Wang of the Industrial and Commercial Bureau chased him in behind his buttocks.

"Xiaohu, our website has been hacked again!" Section Chief Wang went upstairs in a hurry, sweated in his head, and said loudly: "You have to go and check for us again!" ”

"Hacked again?" Hu Yifei was surprised at first, and then sat down slowly, "Didn't you catch all the hackers yesterday?" ”

"Who's to say it isn't!" Section Chief Wang took out a handkerchief to wipe his sweat, "But I didn't expect the website to be hacked again in the middle of the night!" ”

Hu Yifei took out a pen, flipped through the table for a long time, and found a piece of paper, "It's okay, don't worry, let's talk about the specific situation first!" ”

"It's the same as before, the name of the website has been changed again!" Section Chief Wang watched Hu Yifei write slowly, and snatched his pen from him, "Don't register, hurry up and follow me to see it!" The director is angry, and I can't rest this big weekend! ”

Hu Yifei dragged the pen back again, "Did you release the hacker you caught?" ”

"Nope!" Section Chief Wang is really dying, "That child has been at the police station all the time last night, the police station means that the child is small, so he will be detained for three days, and then let their family come over and pay money to guarantee people out." ”

"Then it looks like you've caught the wrong person!" Hu Yifei suddenly realized, "Think about it, that kid is at the police station, and the website has been hacked, and the method is the same, doesn't this mean that the real hacker has not been caught?" ”

Section Chief Wang was dumbfounded for a moment, and then said: "Oh, my Comrade Xiaohu, let's leave that kid alone if it's a real hacker, okay?" ”

"Okay!" Hu Yifei answered, threw the pen on the table, and stood up.

Wang Keda was overjoyed, "Then let's hurry over, the car is downstairs!" ”

"No hurry!" Hu Yifei stretched out his hand, "You first show me yesterday's accident appraisal report and solution!" ”

Section Chief Wang didn't care about it at this time, opened his handbag, and handed over the two reports.

Hu Yifei just glanced at it, and frowned, "Section Chief Wang, this matter is not easy to do!" The reporter is Director Qin's name, so he has to handle this matter! After speaking, Hu Yifei pointed to the new regulations on the wall that I don't know who hung up, and said: "See, we have implemented new management regulations here, who takes over, who is responsible, the case will be in the end!" Since this matter was taken over by Director Qin, according to the regulations, he has to be responsible for it to the end, I am just a small soldier and have no right to interfere! ”

Section Chief Wang froze there suddenly, feeling a cool breath on his back, rushing straight to his head, this Hu Yifei was still a Liba yesterday, he looked stupid and didn't know anything, and he could be happy to give a kind word, why is it like a different person today, and he actually raised the head of their unit. Section Chief Wang really wanted to cry without tears, and said in his heart that he was in a hurry yesterday afternoon, so he changed the appraisal report. Director Qin, who is said to be a dog, is not a working material at first glance, otherwise he would not have been so cautious on the seal yesterday.

This is a fucking cybersecurity reform, it's not as good as before! In the past, I could find a random computer student on the street and give two of you money to solve the problem, but now it's good, and you have to come here. If you can't get the information security monitoring center's handling opinion, the unit's network just wants to pull a two-foot-long network cable, and you have to pay out of your own pocket, and the financial reimbursement only recognizes the processing opinion issued here. This is only a transformation, as for the money for the maintenance of the network, there will be no money, let alone reimbursement, the municipal finance will allocate special funds to the monitoring center every month, and the monitoring center is specifically responsible for network maintenance, if you invite someone from the outside to repair your own network, but you have to pay out of your own pocket, and if something happens in the future, you have to bear all the consequences.

"Brother Hu!" Section Chief Wang now knows who the uncle is, and laughs with him, "We don't care if Director Qin is not Director Qin, I will recognize you, I only believe in your skills, I don't worry about changing someone else!" ”

"Thank you, Section Chief Wang, for your love!" Hu Yifei shook his head and smiled bitterly, "We are not outsiders, so I won't hide it from you, it's really not that I don't help you, I really can't do anything, don't look at me I'm here to work today, but I'm on duty for Weilan Netan!" After speaking, Hu Yifei also pointed to the work duty table on the wall.

Section Chief Wang looked at it and was dumbfounded, the table on the wall clearly stated that Weilan Network Security was 7x24 hours a day, Hu Yifei was on duty on Saturday and Sunday, and the information security monitoring center was on duty from Monday to Friday, and there was only one emergency contact number on weekends. Section Chief Wang wanted to scold people, this bullshit unit has just been established, and there is a bureaucratic style, and there are two sets of duty systems, which are clearly in order to better kick the ball and play Tai Chi!

"Without a work order from the monitoring center, wouldn't it be in vain for me to go!" Hu Yifei smiled and walked to the side slowly, "Section Chief Wang, don't worry, I'll pour you a glass of water first!" ”

Section Chief Wang is soft, but Hu Yifei doesn't eat this set, uses hard, just kidding, and now he is begging for someone, besides, this kind of intern, you come hard, people are not afraid at all, pat your ass and leave, but your own affairs are 100,000 urgent, and if you delay it again, the director will be held accountable by the city, so can you still have good fruit to eat?

"Brother Hu, if you think of a way, you must help me!" Section Chief Wang can't be soft, so he uses super soft.

Hu Yifei handed the water cup to Section Chief Wang, "Why don't you call this emergency number?" As long as the people in the monitoring center can open a work order, we can go immediately! ”

Section Chief Wang had no choice but to dial the emergency phone on the wall, and three seconds later, the phone on the desk behind Section Chief Wang's buttocks rang.

Hu Yifei was taken aback, I damn it, I don't know when the phone in this office is pulling, but he laughed and said, "It seems that no one answered this call!" ”

Section Chief Wang is so angry that he wants to drop his mobile phone, usually these newspapers and television, always like to criticize the Industrial and Commercial Bureau, saying that it is inefficient, a good hand of prevarication, isn't this fucking random report, Lao Tzu must find someone to expose the monitoring center when he goes back, and see who is the well-deserved No.1.

"Brother Hu, what do you think we should do now?" Section Chief Wang is about to go crazy.

"I can't help it!" Hu Yi flew to the desk and sat down, "I don't have their contact information either, or Section Chief Wang, you can come back on Monday!" ”

"Monday?" Section Chief Wang jumped three feet high as if he had stepped on a landmine, and after landing on the ground, he changed his smile, "Brother Hu, it's a big matter of 100,000 urgent, but I can't wait for Monday!" ”

"Then wait, let's see if there is anyone from the monitoring center in a while!" Hu Yifei turned on the computer, "I have a landlord and digging a pit here, do you want to come to two?" ”

Section Chief Wang fell and was about to leave, he really couldn't wait for Hu Yifei, and now he could only find someone to do it out of his own pocket, and there were more than a dozen security companies in Dongyang City.

was about to go out, but Cobra walked in, and when he saw Section Chief Wang's annoyed and angry appearance, he asked, "Xiaohu, what's going on?" ”

"Section Chief Wang of the Industrial and Commercial Bureau said that the website was hacked and he was looking for someone to do the test!" Hu Yifei laughed and said to Section Chief Wang: "Look, I just said to let you wait patiently for a while, no, our Director Hui is here!" ”

Section Chief Wang was about to cry, how could he have the time to settle accounts with Hu Yifei, and grabbed Cobra's hand in the past, "Director Hui, I can be regarded as waiting for you, our website has been hacked for three consecutive days, and it must be solved immediately!" ”

Cobra just passed by the company and came up to pick up something, but he didn't think that he could still encounter this matter, so he said to Hu Yifei: "Xiaohu, if you are free, go and deal with it!" ”

Hu Yifei scratched his head and said, "This matter was taken over by Deputy Director Qin, and there is his accident appraisal report, so I can't interfere!" ”

As soon as Cobra heard it, he knew what was going on, and said that Hu Yifei was young and vigorous in the end, and he was unhappy with who he was unhappy with, and he immediately showed it. He went over and sat down at his desk, looked at the report in Section Chief Wang's hand, and then dialed Qin Shouren's phone, "Section Chief Wang of the Industrial and Commercial Bureau said that their website was hacked, and there is an accident identification report signed by you, what is going on?" ”

Qin Shouren was blind when he heard it, damn, wasn't it all good yesterday, and the problem was solved, he dared to sign his name, why was the website hacked again in a blink of an eye, he said on the phone: "Mr. Hui, things are like this......", this and that for half a day, Qin Shouren didn't say that he was ugly.

"It's not clear on the phone, Section Chief Wang is in the company now, since you are responsible for this matter, then you can deal with it!" Cobra didn't give Qin Shouren a chance to explain again, hung up the phone, and said to Section Chief Wang: "I'm really sorry, I have already notified Deputy Director Qin to come over to deal with this matter!" ”

Section Chief Wang suddenly had two big heads, he thought he was looking forward to a savior, why was the ball kicked to Qin Shouren in a blink of an eye, he hurriedly said: "Big weekend, I don't think it needs to be so troublesome, Xiaohu is also in the company, his skills are good, do you see if you will send him to deal with this matter!" ”

"The company has articles of association!" Cobra was very patient and explained: "Since this matter was taken over by Deputy Director Qin, even if he wants to change people halfway, he must sign and agree to it!" It's okay, you wait a minute, he's probably on his way now! ”

Cobra found a folder from his office drawer, took it out to confirm, stood up, and said, "Xiaohu, you entertain Section Chief Wang!" It looks like he's leaving.

Section Chief Wang was a little anxious in his heart, afraid that Qin Shouren would come over to command Hu Yifei, so he wanted to stop Cobra and delay for a while.

Unexpectedly, Hu Yifei opened his mouth first, "Director Hui, I have a question I want to ask you!" ”

Cobra had no choice but to put down the papers in his hand and sit down again, "Tell me about it, hehe!" ”

"Recently, someone on the Internet gave me a data recovery problem...... Hu Yifei scratched his scalp, a little embarrassed.

"It's okay, let's study it together!" Cobra laughed.

"It's a very strange folder.,After recovering it.,You can see that its capacity is 10g.,But after opening the folder.,But you can't see anything.,What's even more strange is that you can't find this folder under DOS.。 If you make a slight change to this folder, the 10g content will disappear immediately. Hu Yifei smiled, "I thought about it for a week, and I didn't understand what was going on!" ”

"That's it!" Cobra thought for a while and said with a smile: "The situation you said reminds me of a bug in the previous Microsoft system!" ”

Hu Yifei became interested and said hurriedly: "Teacher Hui, let's talk about it!" ”

"That's right, when Microsoft System creates a folder, it doesn't allow the folder name to have "." (Note: the symbol is dotted) this symbol, if you play with . name, the system will automatically filter out that small dot, for example, if you create a folder called 'a...', after confirmation, the name of the folder will automatically change to 'a'. Cobra laughed, "But Microsoft is negligent that under their DOS it is possible to build this kind of . folder, and then there is a **ug! ”

Cobra turned on his computer and showed Hu Yifei that he had set up two folders in the root directory of the D drive on his computer, called A and B, and then put a picture in folder A, called "Zhang San", and a picture in folder B, called "Li Si".

"Look at it now!" Cobra opened the system's built-in DOS command console, "I'm now changing the name of folder B to 'A...'. ”

Cobra typed in the command,After prompting the modification successfully,He opened the D disk directory again,It's two folders A and A...,If you don't look carefully,You really can't see the small dots behind。

"So there's a bug!" Cobra clicked on folder A, and the picture Zhang 3 that he had placed before appeared in it, but he clicked on the folder A..., and the picture Zhang 3 appeared in it.

Section Chief Wang is an electric white, pouting his ass and watching it for a long time, but he didn't find any difference. Hu Yifei saw the doorway at a glance, opened folder A..., and saw the contents of folder A, but the original second picture Li Si was gone.

"How so?" Hu Yifei asked.

"It's just a bug!" Cobra smiled, and then typed under dos, showing the contents of the two folders respectively, and only the picture Zhang 3 was displayed, and the picture Li 4 was completely invisible.

Hu Yifei immediately understood the connection between this and the strange folder on Dr. T's hard drive, since it was a bug, it meant that the picture Li Si did not disappear, but because the bug was hidden and the system could not display it. Hu Yifei hurriedly asked, "Is there a way to restore the original picture?" ”

Cobra entered the command under DOS again, and the command was very simple, that is, to move the folder A... The picture "Li Si" inside goes to folder A, after entering, and then open folder A, pictures Zhang San and Li Si both appear.

"See, if you can know the name of what's hidden in this folder, you can call it out!" Cobra explained, "But if you don't know what the name of the thing inside is, there is no way, if there is something in such a folder, you can't delete it in the usual way, it's a headache!" ”

Hu Yifei clenched his fists, very excited, it seems that there is no way to recover the files on the hard drive.

"This bug is very early, hackers can peek into the contents of other folders outside of their permission as long as they create folder names for their surnames, and later they are even used to hide virus Trojans, because antivirus software can't search these folders. Microsoft later released a patch to fix this bug, but I heard that someone made a more complex shadow file based on this vulnerability, its principle, like a calm water surface, you can see the reflection of the water surface, you can also see the water in the clear sand, fish playing, but as long as you throw a stone into it, you can't see anything. Cobra smiled and turned off the computer, "I think you just admit defeat, this kind of shadow file can't be recovered!" ”

"What if you could know the name of the document inside?" Hu Yifei asked.

Cobra shook her head, "I've only heard of it, but I haven't seen the actual shadow file, but you can give it a try and see if you can get the fish out inside!" Hehe. Cobra smiled and grabbed his papers, "Okay, no other problems, I'll go first!" ”

"No, thank you, Mr. Hui!" Hu Yifei thanked him, still thinking about this shadow file in his head, last time I heard the tarantula say that the program has a shadow, and this time I heard cobra say that the folder also has a shadow, it seems that this shadow is mostly a bit reliable!

"Brother Hu, what kind of fish?" Section Chief Wang still doesn't understand where this fish came from, and the more he doesn't understand it, the more he has to ask, which is a typical characteristic of a layman.

"Don't think about this fish! It's better to wait for Director Qin to come with peace of mind! After Hu Yifei finished speaking, he ran to his computer and tried to repeat what Cobra had just done, but found that he couldn't create a folder with small dots on his computer, and it seemed that the system he used had been patched.

Hu Yifei shook his head, wondering in his heart, Cobra was actually playing with an unpatched sieve system!

After more than ten minutes, Qin Shouren finally came, and when he entered the door, he saw Hu Yifei sitting there in a daze, so he shouted: "Hu Yifei, what's the matter with you?" Obviously people are in the company, why don't you do things! Everything is waiting for me to deal with, what does the company want you to do! ”

Hu Yifei was not angry, stood up and said with a smile: "Director Qin, there is no work order, what is the matter if I go, and I can't report the bill when I come back, right?" ”

When Qin Shouren heard this, his face softened slightly, he thought that Hu Yifei went on strike because he was dissatisfied with his own credit, he held back the fire in his stomach on the way here, even Daqiang's group of birdmen went on strike, and now even a little intern dares to rebel, do you really think that your deputy director is a vegetarian, how do you know that Hu Yifei, this kid, does not work, but he is afraid that the round-trip expenses will not be reimbursed!

"Well, you still have to go through the charter, I'll give you a ticket now!" Qin Shouren used to bill in the past, but he was very disdainful in his heart, damn, the round-trip fare is only three yuan, because you tossed Lao Tzu over these few cents, I think your kid is just like that.
