Chapter 240: The Product Salesman

"It's really worthy of being the big boss of the Soft Alliance, the number one security expert in China, look at it, look at it!" Director Ding was broken at this time, and looked back and forth at the server, "What is the master, this shot, in less than two minutes, this password has been unlocked, amazing, amazing, admire, admire!" Director Ding gave Liu Xiao a thumbs up, his face full of admiration.

The experts of the two network supervisors were also stunned, this is really a god, a letter V will unlock this password, the head of this soft alliance is the head of the house, there are really some ways to do it!

Liu Xiao smiled bitterly, walked over, called up the attack record just now on the server and looked at it, and found nothing special, this is because the attack log has been cleared.

Liu Xiao shook his head, let go of the server, and stood aside thinking, this is a master, he has done it so seamlessly, he can easily delete the account after coming in, change the password, and clear all the logs, but no network administrator can find out, so what is his purpose?

"Mr. Liu!" The network supervisor tinkered with the server for a long time, and then turned around and looked at Liu Xiao, "I have restored the tampered web page, do you see if you can transfer the domain name now, you can't always let people look at that empty website!"

"Okay, turn around, turn around!" Director Ding smiled on the side, and the problem was finally solved.

The network supervisor was about to make a move, but Liu Xiao said: "Don't worry, don't worry!", and returned to the server after speaking, "I'll take a look!"

Liu Xiao opened his backpack, took out his notebook, and then connected the network cable, and linked it to the server, "I'll test it first, try to virtualize the state that the server has been connected to the network normally, and see if the other party has any tricks left!", Liu Xiao explained to everyone a little.

Liu Xiao ran a tool, re-set the IP of his computer and the server, and then ran a virtual domain name management system, virtually bound the IP of the server to his correct domain name before, and finally entered the domain name address on his machine to access the server normally.

As soon as the page opened, Director Na Ding shouted again, "That's right, that's it, it's this page, it's okay now!"

Liu Xiao didn't say anything, just refreshed the page again, and when the page opened again, everyone was stupid, especially Director Na Ding, whose smile was directly frozen on his face, because it had been tampered with again, it was still the appearance of the red letters on a black background just now.

"How can this be?" the expert of the network supervisor was a little puzzled, "I checked it just now, and the back door on the server has not been opened!", can you not wonder, this server has not been connected to the network yet, why has it been hacked again.

"This is not a back door!" Liu Xiao smiled, "It's a mechanism program!", Liu Xiao really felt very funny in his heart, this was a competition with himself, he played a trick on the mechanism program, and he returned it to himself, fortunately, he had expected that it would not be so simple, a small test, and he tried it, otherwise when the domain name was transferred back, it would be over. Tomorrow, someone will definitely tell a joke, saying that the summit website in Thunder City has been hacked, and after a long time, it has finally been repaired, but the next second it is repaired, it will be hacked again, and people will lose people twice in a row!

"God!" The expert of the network supervisor also smiled, "Mr. Liu, you are really a god, how do you know that the other party will bury the procedures?"

"I'm not an iron-mouthed half-immortal, I can predict the prophet, I just did a test for safety!" Liu Xiao smiled and put away his tools, "We do safety, when dealing with this kind of thing, we must be careful, and we can't fall twice in a pit!"

"Yes, yes, what Mr. Liu said!" the expert of the network supervisor smiled, "Then what do you say to do now?"

"It's very simple, just find out the organ program!" Liu Xiao stood up and pointed to the computer screen, "According to the test just now, I preliminarily judged that there are two prerequisites for the organ program to be triggered, one is the domain name binding, and the other is that there are external users accessing the web page normally, I can verify this for you again!"

Liu Xiao said and walked to the server again, and found out the normal web page to the experts of the network supervisor, who knows, found that the account password of the server has been changed again, Liu Xiao is helpless, and enters Bobby McKinnon again, enters the server, deletes the tampered web page, restores the normal web page, and then opens the normal web page on the server, refreshes it several times in a row, and the web page is normal and has not been tampered with.

After finishing it, Liu Xiao returned to his computer, opened the virtual tool again, and accessed the web page of the server after setting it, and when it was refreshed, it was tampered with again.

"Everyone has seen it!" Liu Xiao smiled, "Only when an external user uses a domain name to access, the organ program will be triggered, so I judge that this organ program must be in the file that needs to be called on the homepage of the website!"

Liu Xiao restored the server again, reopened the normal web page, and looked at everything displayed on the homepage, "Let's take a look, let's see where this organ program can be hidden!"

A group of people are all in front of the screen, this is not to see anything, the page is nothing, simple, the background is the Lei City Government, in the middle is a news scroll, timely broadcast of various text reports of the summit, on the right is the demeanor of the people, is the photo of the guests, below is the schedule and tips of the conference, on the left is a video window, at this time is playing the video of Mayor Na Dong announcing the opening of the summit.

"Nothing special!" Several people looked at the eyes sour, and they didn't find anything special, all the documents were displayed normally.

"Mr. Liu, it's better for you to analyze and analyze for everyone!" The person in the network supervisor was also very modest, "These documents can all be displayed normally, I really can't see anything abnormal!"

"In fact, the organ program can be triggered, the premise is that its host program can run normally, so that it will trigger its organ message, only some extremely clever organ programs can open the organ message when the host program is not running, but people who know this kind of technology, the world can't find five people, they don't have time to hack our summit website!" Liu Xiao smiled and looked at the web page, "Now all the files can be displayed normally, which means that these files may be the host of the organ program." ”

"Oh~", a few people realized, it turns out that there is still this saying, "Then which one should we start with?"

"Eliminate the biggest suspicions!" Liu Xiao pointed to the video that was playing, "The master can make the organ message execute in any file, and the general person who is just getting started with the organ program technology can only use the executable vulnerabilities of some specific files to open the organ message, this website is eligible, only pictures and videos, relatively speaking, the probability of adding executable code to the video will be greater." ”

"Then I'll pinch this video first!" After the expert of the Internet Supervision Department finished speaking, he found this video in the files on the website, changed the name of this video, and then moved it to another place.

After doing all this, Liu Xiao opened the web page of the server on his computer again, and except for the video that was not played, all other places were displayed normally. Liu Xiao refreshed again, the page reopened, it was still the same, except for the video, the rest were displayed normally, and the page that had been tampered with did not appear this time.

"It's done!" The expert of the network supervisor was excited, "It seems that the agency program is hiding in that video, it's really amazing, it's the first time I've encountered this situation, what do you think about this attacker, does he deliberately want us to make a fool of ourselves many times?"

"Maybe, maybe not!" Liu Xiao said an ambiguous word, he knew that the other party might not be for the summit, it was very likely for himself, and paused, "All videos and pictures must be checked, and if there are problems, they must be deleted, and it is best to find the original file and replace it." ”

"Yes, yes, yes!" Director Ding nodded, "Safety first, be careful, we have backups of these files, but unfortunately there is no website program on the backup server, so we are so passive!"

"That's good!" Liu Xiao nodded, "But you must pay attention to network security work in the future, for such an important summit, there is not even a decent anti-spyware software on your website server!"

"Yes, yes, yes!" Director Ding still nodded, "I'll let them install the best right away now, and use the anti-spyware software of the soft alliance, what do you think of this?"

Liu Xiao shook his head helplessly, as if he was here to promote products, he was really depressed, but Liu Xiao didn't care about it, whatever he said!

Gu Zhendong on the side saw Liu Xiao's unhappiness, and immediately shouted: "Director Ding, how are you talking, the city has entrusted you with such an important matter, you should have used the best safety products, is there any doubt about this? Besides, if Mr. Liu didn't sell me a little face this time, you would have used a sedan chair, and you might not have been able to let Mr. Liu personally come over to do this anti-invasion test for you!"

Director Ding was stunned for a moment, then reacted, and hurriedly compensated no, "Look at my mouth, Mr. Liu, don't be surprised, I don't mean what you think, I'm stupid, don't worry, I will do a good job in this safety work in the future, and I will use the best for all products!"

Liu Xiao smiled and waved his hand, "It's okay, I didn't think much about it, don't take it seriously, hurry up and recover, it's been delayed for a long time, I'm afraid the city will hold you responsible." ”

"Yes, yes, I'll arrange it!" Director Ding said, and immediately arranged for someone to find a backup, ready to replace all the files that may be infected by the agency's programs, and then asked people to call the 24-hour sales phone of the soft alliance to urgently buy the software of the soft alliance.

"That's right!" Liu Xiao looked at Director Ding, "This video file that is infected with the agency's program, I want to copy a copy and go back for research!"

"This is not a confidential thing, Mr. Liu wants to study it, although I take it, this thing is useful to you, but in my place, it is a scourge, Mr. Liu wants to take it away, we are too late to be grateful!" Director Ding was full of honey, just this mouth, and said that he was stupid.

Liu Xiao couldn't cry or laugh, shook his head, copied the video file to his computer, and then put the computer into his bag, and then looked at the two experts of the network supervisor, "I'll leave it to the two of you here, if you bother more, I'll leave!"

The two network monitoring experts shook hands with Liu Xiao, "Mr. Liu, go slowly, if we are free in the future, we hope to communicate with you more, we can learn a lot today!"

"Learn from each other!" Liu Xiao smiled, "If you two have any problems in the future, you can come to me at any time, and we can analyze and discuss together!", as he spoke, Liu Xiao took out his business card from his pocket and distributed it to the hands of the two Internet supervision experts.

When Liu Xiao and Gu Zhendong came out of the computer room, the two network supervisors looked at Liu Xiao's business card and sighed: "It's really worthy of being the number one security expert in China, there is nothing to say about technology, even people are so modest, people can make the soft alliance so big, it's really not blowing." If such a person is underdeveloped, it is really unreasonable!"

"Gotcha, let's hurry up and clean up this mess!" another network supervisor instructed, "You can put away your business card, let's show it off when we go back, let them come here to solve the problem before, no one wants to, I regret killing them now!"
