As soon as I went out, I happened to meet the person who sent the work order, Liu Xiao's appearance startled the person, "Liu Xiao, what's the matter with you? What's wrong with your hand?" The man was very concerned, and he wanted to see Liu Xiao's hand when he came up.

Liu Xiao protected his hand, "It's okay, there is water on the ground, I slipped, you go find someone to mop the floor of the bathroom, don't let the people behind you fall too." ”

"Your hand is fine, it looks very serious, why don't you go to the doctor?" the man seemed a little uneasy.

"It's okay, it's just a knock, it's a little broken, I have a band-aid in that drawer, and Yunnan Baiyao, you can rest assured!" Liu Xiao waved his hand.

"Then I'll go to the cleaner!" The man took one last look at Liu Xiao's hand, and then turned around and went busy.

Back in his seat, Liu Xiao took out a few band-aids from the drawer, pasted them all to the wound, and then tried to knock on the keyboard a few times, and a heart-piercing pain spread from the backs of his two hands, causing a layer of fine sweat to suddenly appear on Liu Xiao's forehead.

"***!" Liu Xiao gritted his teeth, blew a few breaths at the wound, and then bent over and pressed the power button of the computer.

After the computer was turned on, Liu Xiao looked at the authorization letter again, and then he noticed the date under the authorization letter, the electronic company authorized the soft alliance to conduct security inspections, which was actually two weeks ago. "Two weeks, two weeks......" Liu Xiao couldn't help but smile bitterly in his heart, how could he wait until today to send down the business he received two weeks ago, could it be that the company is not manpower enough to be discharged?

Now that he knows how he was deceived, Liu Xiao has a way to bypass the deception trap they set for himself, and successfully log in to the server that originally belonged to the electronic company, Liu Xiao wants to find the means and methods of ufeifan from this server, figure out the details of this server, and then he will dig the same pit for ufeifan and them on this server, how the other party let himself fall in, and how he let the other party fall in.

One day, for Liu Xiao, feifan They invaded this server and did tricks on this server, it must have been many days ago, Liu Xiao wanted to find the traces of the other party from the complex data on the server, it was not easy, not to mention that it was tantamount to looking for a needle in a haystack from these data.

But Liu Xiao has to do this, and he can only do this, he now has a preliminary understanding of ufeifan's attack, these guys have a weakness, that is, if a trick works, then they don't mind using this trick again, a Trojan encryption method they can continue to use for two years, and the method of framing people has been used for more than three years, just by virtue of this, Liu Xiao dares to guarantee that if they are allowed to invade this server again now, those guys will definitely not want to, how they got in last time, how they will come in this time。 And Liu Xiao just wanted to take advantage of this and dig a big pit for those guys on the path they often "walked".

Liu Xiao got all the data records on that server, fortunately, he found out that the gang had dug a trap for himself a few hours ago, and it seems that they were also afraid that the server would be abnormal for too long and expose themselves. But in this way, it is tantamount to helping Liu Xiao a big gang, they dig the trap in the middle of the night, and now it is just a short time after going to work, this time is not working time, so the access data generated by the server is very small, so there is a lot less trouble, because there is no other data to interfere with Liu Xiao's sight.

Liu Xiao successfully found out the traces of the invasion of Ufeifan, and all he had to do was to analyze this data and determine how the other party invaded. In order to make his analysis purposeful, Liu Xiao uploaded all his detection tools to that server, and he wanted to know what vulnerabilities existed in that server.

If you can't analyze the other party's intrusion methods from the data, then you can only attack all these vulnerabilities to see which vulnerability is the attack to produce similar data, so that you can basically determine the other party's attack methods, but there is a little bit of luck, sometimes, many different attack methods will also produce very similar data.

The whole company was puzzled by Liu Xiao's abnormal behavior today, and I usually didn't see Liu Xiao so desperate, his hands were broken, but he was still tapping the keyboard in front of the computer, the wound was pulled open again and again, and the band-aid had already been infiltrated by blood. At lunchtime, Liu Xiao, who is usually the most active, actually sat firmly in Diaoyutai, sitting in front of the computer and staring at the characters on the screen, screen after screen, and I didn't know what he was looking for in it, but looking at the expression, it was as if there was gold hidden in this pile of characters.

In the end, it was the front desk MM who bought Liu Xiao food, and while no one was paying attention, he sneaked to Liu Xiao's side, "Hey, Liu Xiao, what's wrong with you today, don't be so desperate, hurry up and eat something!"

Liu Xiao raised a hand and signaled MM not to speak, his analysis at the moment had reached the most critical moment, and he was one step away from grasping the truth, Liu Xiao flipped through the pile of data, and wrote down a character on the paper in his hand, and then turned a paragraph, and remembered another one.

"You can't be sick, are you!" MM stretched out her hand and touched Liu Xiao's forehead, she felt that Liu Xiao was a little confused.

As soon as his hand touched Liu Xiao's forehead, Liu Xiao jumped up from the chair, "He's ***, finally got done by Lao Tzu!"

Liu Xiao's sudden body, coupled with the foul mouth, scared MM a lot, thinking that Liu Xiao's nerve was wrong, he took two steps back, and looked at Liu Xiao nervously, "You...... What do you want to do?"

Liu Xiao looked at the screen proudly, stretched his waist, and then his eyes were retracted, and he caught a glimpse of MM on the side, and said strangely: "Huh, why are you running to me here? ”

MM was completely stupid at this time, came back to his senses, reached out and touched Liu Xiao's forehead again, looked puzzled, and muttered in his mouth: "Don't burn, is it a demon?"

"What do you ask!" Liu Xiao looked at the MM with a smile, "What are you touching my forehead, I don't have a fever!"

"It's okay, it's okay!" MM waved her hand again and again, she was made furious by Liu Xiao's abnormality, "I'll bring you a boxed lunch, hurry up and eat, I'll go back first!" After MM finished speaking, he turned around and left, not daring to stay here with Liu Xiao for a moment.

"Lunch box?" Liu Xiao turned around and glanced at the time on the computer, only to find that it was already past the point of eating, and then he realized that he might have been too focused before, so he turned back to MM's back and said loudly: "Thank you, I will invite you to dinner in the evening!" After speaking, he sat on the chair and began to pull the lunch box.

When MM heard this, he ran back to his front desk as if he was running away.

When Lan Shenghua was eating at noon, he heard the employees talk about Liu Xiao's abnormality, put down his food and ran back to see, but he happened to see this scene, and immediately let out a sigh of relief, shook his head at Liu Xiao, who was gobbling up there, turned around and walked out again.

After eating, everyone returned to their seats one after another, ready for the afternoon's work. Liu Xiao sat in front of his computer at this time, took a deep breath, and found out the attack method of ufeifan, and it was the last critical moment, because Liu Xiao was ready to invade the confidential server again. If it's just an intrusion, that's fine, and what Liu Xiao wants to do is to make a hole in that confidential server and create a hole in the server that originally had no loopholes.

Confidential servers, the security level is very high, and there are people who are specially responsible for guarding them, even super hackers, and they dare not say that they can 100% succeed in the invade, even if the intrusion is successful, it is difficult to guarantee that it will not be discovered. Liu Xiao invaded in the morning in a daze, and it was already a fluke to be able to get out of the way, and now he actually has to go in again, what is even more outrageous is that he still has to open an opening on the already very safe server of others, and is ready to let ufeifan in, the difficulty is so high, it is conceivable, it is estimated that only a madman dares to think so. You know, the administrator of the confidential server is not stupid, once the other party finds out, the tracking program will be activated immediately, with the powerful resources of the military, it is easy to find someone to come out. Therefore, the evil sword didn't explain back then, and just escaped first.

Liu Xiao checked all the tools again, and there could be no mistakes. He is very grateful to one person in his heart at this time, that is, treading snow without a trace, the invasion method of stepping on snow without a trace is the same as his screen name, stepping on snow without a trace, if it weren't for this, Liu Xiao is afraid that he would have already fallen into the hands of ufeifan at this time, hacking into a confidential server, and there is no return. It was also the snow without a trace that forced Liu Xiao to analyze the data packets again and again, and his solid skills allowed Liu Xiao to determine the means of invasion in such a short period of time.

"I hope it will succeed this time!bless me!" Liu Xiao suddenly prayed at this time that stepping on the snow without a trace would bless him, not the sky or God.

Liu Xiao made a springboard, this time he directly filled in the IP address of the confidential server, and then launched an attack, unexpectedly, the tool did not respond at all!

"What's going on?" Liu Xiao was a little weak-hearted, it couldn't be that his attack in the morning was discovered, then this military master was too powerful, and in just a few hours, he found out the loopholes and patched them.

But looking back and thinking about it again, Liu Xiao felt that this possibility was too small, he obviously didn't alarm the other party in the morning, and the amount of data on the communication server was so large, even if the other party found out, it was impossible to repair it so quickly. Liu Xiao felt that his springboard might have been blocked by that server, this kind of confidential server has strict access restrictions, and not everyone can access it.

In order to confirm his guess, Liu Xiao removed the springboard and used his computer to send a spy message to the confidential server, but there was no return, but Liu Xiao sent a message to the server of the electronic company, only to find that his spy message was not only successfully transferred to the confidential server, but also confirmed this by the returned news.

Liu Xiao finally figured out that the nature of this electronic technology research and development enterprise should be a military scientific research unit, so his server can access the confidential server, which is not in the military network, and the strange port opened on it may be used for confidential communication between the military network and these military enterprises.

In this way, ufeifan has really put a lot of effort into framing himself, all links are indispensable, and it is not easy to put so many conditions together.

Liu Xiao snorted coldly, and still filled in the IP address of the electronic company's server on his attack tool, and after the attack was successful, Liu Xiao invaded the confidential server again.

Just like in the morning, Liu Xiao first checked the status of the server and found that the administrator had been active for a while, but he did not find out about his intrusion in the morning.

Liu Xiao was relieved and hurriedly uploaded the tools he had prepared, thanks to the transfer station that ufeifan had made for himself, the confidential server always thought that he was exchanging data with the server of the electronic company, so he did not detect the abnormality of the data.

All the actions were automatically completed by the tools that Liu Xiao had made in advance, and it was only a few seconds before and after, Liu Xiao saw that the tool was executed, sent a message to test it, and made sure that it was correct, so he didn't dare to delay, quickly cleared his footprints, and exited the confidential server.

Liu Xiao leaned back in the chair and gasped, but it was done, and the process was quite smooth. Outsiders may think that this process is thrilling and dangerous, but the difficulty inside is only understood by Liu Xiao. Giving the other party's server an opening is like opening a crotch on the pants of a person who is very attentive to his image, and you can't let him know that he has opened his crotch when it's over. It's like the emperor's new clothes, obviously running naked, and thinking that he was wearing the most luxurious clothes in the world. The Emperor's IQ is not good, but the administrator of the secret server is not a vegetarian, and it will take some skill to deceive them.

Liu Xiao returned to the server of the electronics company and modified the settings of ufeifan, which was considered a big hole dug, and he just waited for someone to jump in.

Sitting on the chair and fantasizing about the scene after being fooled for a long time, Liu Xiao's heart was also half of the fire, and he sat there alone and was silly.

"Liu Xiao, what are you happy about?" someone patted Liu Xiao on the shoulder from behind.

Liu Xiao looked back and saw that it was the person who sent the work order, Liu Xiao never asked who this person's surname was, so he had to say: "It's nothing, it's nothing, I just remembered a funny thing." ”

"Just now I went out on an errand, passed by the pharmacy, and brought you some medicine by the way. As he spoke, the man put a small plastic bag on Liu Xiao's desk, which contained some newly bought band-aids and some anti-inflammatory and pain-relieving products.

"Thank you, it's so troublesome for you!" Liu Xiao quickly got up and thanked him, it was not easy to meet such an enthusiastic colleague.

"It's okay, you're welcome! You're busy, I'll go over there and have a look!" the man smiled and left.

Liu Xiao tore off his few pieces of bloody band-aids, and then prepared to replace them with new ones, but he looked left and right, and the wastepaper basket he put at his feet was gone, so he wanted to find a piece of paper to wrap up these old band-aids, and threw them away after a while.

At the moment, Liu Xiao didn't care about pasting a new band-aid, he dragged it over and the keyboard began to crack again, he dug all the traps, but forgot to put a bait on the trap, this bait is the work that Lan Shenghua sent to him today, the safety inspection report.

When he got off work in the afternoon, Liu Xiao finally got it done, hurriedly sorted out the order, and didn't bother to check it, so he went to the small office area with this safety check.

Knocking on the door, Liu Xiao put the safety inspection report on Lan Shenghua's desk, "This is today's test report, and this is the information taken from you in the morning, and now I will return it to you!"

"It's all done?" Lan Shenghua looked at Liu Xiao with a smile.

"Today's server is really difficult to handle, and it almost scared me to death, but in the end, I was able to get it done!" Liu Xiao smiled.

"Let it go, I'll just watch it later!" Lan Shenghua smiled even more, "It's time to get off work, you can go back first." ”

Liu Xiao said hello, went out to pack his things, and left the soft alliance.

As soon as he left, Lan Shenghua slowly opened Liu Xiao's test report, only glanced at it, and suddenly lost color, "No, what's going on?

Everyone in the room looked over, not knowing what was wrong with Lan Shenghua, the boss sitting in the corner frowned, and asked, "Old Lan, what's going on, don't be surprised, make it clear!"

"This kid didn't give us the test report of that confidential server at all!" Lan Shenghua threw the report on the table, "It's the security report of the server of that military enterprise!"

The people in the room were all stunned, their first thought was that they had been busy for the past two weeks, and they were casting bait and pulling a big net, and the capital was not less, and the coolies were not less, and in the end the bait was eaten, but the fish ran away, it was really fucking frustrated! This Liu Xiao is too powerful, he was not even bypassed to the confidential server, but how did he see through this ecstasy array.

Liu Xiao had already gone downstairs to stop the car at this time, and what he wanted in his heart was to hurry home and send a message to Treading Snow without a trace, telling him that he sincerely thanked him, without him, he might have been plotted by others today, and it was impossible to turn around and "plot" against others.
