After Liu Xiao arrived in Russia, Stepo did not arrange for him to experience the Great Spider System directly, but settled him down first, and then waited for the notice from the military and the government.

However, Liu Xiao is not idle, he now has one thing on his head, to find the loopholes in the strategic-level system, and then follow the vine to see if he can find any clues about the knowledge system of treading snow without a trace and the wild goose phonograph, so he is also happy to be idle and hide in the hotel room to ponder about it.

"Bang bang!" Liu Xiao was thinking about the pain in his brain when he suddenly heard a knock on the door.

Liu Xiao rubbed his temples and walked over, opened the door, and found an old man standing outside, not a waiter from the hotel, nor a person from Steko, Liu Xiao was a little puzzled, "Who are you looking for?"

"It's Mr. Liu Xiao from the Soft League, right?" asked Lao Maozi.

Liu Xiao nodded, "Yes!", and figured out the origin of the other party.

"Mr. Qian asked me to send you something!" Lao Maozi finished speaking, and handed a small document bag to Liu Xiao.

"Mr. Qian?" Liu Xiao was stunned for a moment, and then thought that this might be Qian Wanneng, so he nodded and said to the other party: "Thank you, it's troublesome!"

"You're welcome!" the other party said and left, without much delay.

Liu Xiao pinched the document bag, thinking that it should be a USB flash drive, and couldn't help but be a little strange, "What is the fat man doing, so mysterious! Isn't it okay to call me directly, what is so important, and people have to chase them to Russia!"

Back to the table, Liu Xiao opened the file bag, and it was indeed a USB flash drive, as well as a business card, which read "Internationally renowned and rich, Mr. Qian Almighty", Liu Xiao shook his head and chuckled, Qian Fatzi's business card is really 'only this one, no other semicolon', and he doesn't even need to look at the material of this business card, he also knows that it is his, and others print this kind of business card, and they are afraid of being embarrassed. Liu Xiao put the card away carefully, the cost of this business card is as good as a good car, although Liu Xiao does not have a mobile phone to match it, but he is reluctant to throw away this card.

Connecting the USB flash drive to the computer, Liu Xiao found that it was a small file inside, and when he opened it, he looked at it, but it was all garbled characters, which seemed to be encrypted.

"Mysterious and secretive!" Liu Xiao shook his head, what's wrong with the fat man, such a small document, you don't have to guess that there are not many goods in it, he specially asked people to send it, even if it is not it, why is it still densed, as for it!

I thought so in my heart, but Liu Xiao hurriedly called up a decryption tool, and after checking, he didn't know what method this file was encrypted. Liu Xiao was really stunned at this time, he couldn't guess what the fat man was doing, he had come all the way to send such a small file, but he used a very clever encryption method, did he want to let himself see it, or didn't want him to see it.

Liu Xiao shook his head, "It seems that you have to use real guys!", Liu Xiao connected to the hotel's network, and began to download those real guys at the bottom of the box from several backup points distributed on the network.

"Atli encryption method!", with his own special decryption tool, he immediately got the result, Liu Xiao smiled a little, this encryption method is not very powerful, but it is rarely used, the military of some European countries has used this encryption method, but it has been eliminated for a long time, and the fat man doesn't know where to find the master, even this old-fashioned encryption algorithm has been turned out. This is also thanks to Liu Xiao, if someone else is replaced, it is estimated that they will not have this set of encryption algorithm decryption tools.

Liu Xiao called up the decryption tool, and in just a few seconds, he restored the encrypted file, he opened the file excitedly, wanting to see what kind of medicine was sold in the gourd of the fat man, and Liu Xiao was dumbfounded when he saw it, or garbled code, "This fat man won't be playing me, can you let me see these garbled codes?", Liu Xiao was completely depressed, if it was code, even if it was binary code, he could still guess what it meant, but how to guess this garbled code!

Liu Xiao scratched his head, he really couldn't understand what this fat man meant.

After staring at the garbled characters for a long time, Liu Xiao suddenly thought of a possibility, this fat man would not have used multiple encryption, thinking of this, Liu Xiao hurriedly used a decryption tool to check the file. As soon as the results came out, Liu Xiao smiled, he really guessed correctly, this fat man really used multiple encryption, and the means of encryption are not the same, after the Atli encryption method, it turned out to be Bellamy's encryption method, this encryption method is more powerful, the military of country F has been using it, and it was eliminated until a year ago, and I don't know where the fat man got it from.

But this is not over, Liu Xiao opened the decrypted file and found that it was still garbled, there was no way, so I had to continue to solve it, the encryption methods used by Qian Fat Man are really varied, and one is more difficult than the other, and when the solution reaches the eighteenth, it turns out to be the North encryption method, which is a new encryption method that has just been adopted, the algorithm is extremely complex, known as the most complex encryption algorithm in history.

Liu Xiao wiped the sweat on his head, "Fortunately, it is the most complex encryption method in history, not the most difficult decryption method in history!", Liu Xiao was about to collapse by the fat man, this fat man did not seem to send documents to himself, but seemed to come to test his decryption ability, Liu Xiao had a feeling of passing five levels and cutting six generals, and he was about to vomit blood.

"If there is still a layer of this solution, Lao Tzu will not solve it, and call the fat man directly!", Liu Xiao tossed for a long time, but still couldn't see the content of the document, and he was already a little impatient.

Fortunately, this happens to be the last layer of encryption, Liu Xiao breathed a sigh of relief, the North encryption algorithm is already the most complex algorithm in history, if he goes any further, he can't imagine what encryption algorithm Qian Fat Man can come up with, this is already reaching Liu Xiao's limit.

The document is really very small, there are less than a thousand words in total, Qian Fatzi found someone to dissect the "mosquito", this document is the result of the autopsy: as Liu Xiao guessed, there is something else in the mosquito, Qian Wanneng invited the best nano engineer in the world, only to completely dissect the mosquito, inside is the electronic structure, there are detection devices, sensitive components, memory, Processors, these can be judged based on appearance, but there are still many components that don't know what they are used for; Qian Wanneng wants to figure out what this mosquito is for, but unfortunately the world's best nano engineer he found can't do anything about it, and no device can read the information of the memory; there is no conclusion about why this mosquito suddenly failed and fell into the chassis.

Liu Xiao sighed, he could basically conclude that the invasion that day was caused by this mosquito, and the plot that only existed in science fiction movies really happened!

At the end of the document, Qian Fatzi advised: "After reading it, the document will be destroyed immediately, remember to remember!" Liu Xiao suddenly realized that Qian Fatzi had personally sent these hundreds of words from thousands of miles away, and used eighteen layers of encryption, he was so cautious, it turned out that he was afraid that IND would know that he was secretly dissecting IND's "hacker mosquito".

After figuring out the reason, Liu Xiao couldn't help but shake his head and laugh, this money fat man is so cute, he thought this was an anti-theft lock, add a few more, people can't untie it? This eighteen layers of encryption, it seems that he only tossed himself, Liu Xiao laughed, and completely smashed the document, how powerful the intelligence level of IND is, he knows, this document can't be kept, even if he is not afraid of IND, but it can't bring trouble to Qian Wang!

After confirming that the file was shredded, Liu Xiao frowned, according to this view, even if he gave himself half a year more, he would not be able to fight ind! ind's advantage is not only in network security, they can create such a sophisticated mechanical mosquito to perform hacking tasks, which shows how powerful a technical backing they have behind it. A small mosquito has too much cutting-edge technology in its body, which is not something that a cyber espionage organization can do.

"***, this time it's planted!" Liu Xiao couldn't help but be a little worried, if it was just a hacker technology, he still had a glimmer of hope for catching up with Yan Gramophon in half a year, but if IND used these cutting-edge technological means on the soft alliance, then the soft alliance would have no power to fight back at all, and could only wait to be beaten. Liu Xiao himself loses and loses, it's nothing, anyway, for more than two years, under the hands of Treading Snow without a Trace, he has never won, but now it is different, he has a soft alliance in his hand, this big guy who has just improved a little and carries the expectations of himself and many people Once the big guy is crushed by IND, the consequences ......

Liu Xiao shook his head, he didn't dare to think about this consequence, he regretted it a little now, he shouldn't have been so impulsive at the summit of country F, he boasted a lot, but put the soft alliance in a situation where he could never recover, this is not the result that Liu Xiao wants. Even if he turns back time, I'm afraid that in the face of that scene, Liu Xiao will still make the same decision, but Liu Xiao really regrets it now.

was depressed, there was a knock on the door again, Liu Xiao cleaned up all the tools on the computer, and then went to open the door, and there were people from Steko standing outside.

"Mr. Liu, we have been notified, we can go!" said Steko's face was overjoyed.

"Okay, I'll clean up, I'll go with you!" Liu Xiao let Steko's people into the house, packed up his things, locked the computer, and followed Steko's people out of the door.

After about 40 minutes of walking, the car stopped in front of a red, extremely Russian-style building. After Liu Xiao got out of the car, he saw a sentry standing at the gate in front of this building, with a sign inserted at the door, which was very conspicuous, Liu Xiao did not know Russian, according to domestic habits, he guessed that this sign should say "Military Control Zone"!

At this time, there was an old man in his thirties standing at the door, wearing a military uniform, looking very majestic and straight, with a wise face, holding a thick cigar in his hand, and was swallowing clouds and mist.

"Mr. Liu, please come with me!" Stepko's man greeted Liu Xiao, then walked towards the gate, and in a blink of an eye chatted with the old man in military uniform, it seemed that they should know each other very well.

Liu Xiao stepped forward, and the old man in military uniform pinched the cigar, put it in his pocket, and then stretched out his hand to Liu Xiao, "Hello, Mr. Liu Xiao, I have heard of your name for a long time!"

Stepco's people were busy introducing Liu Xiao, "This is Colonel Bonev, the most powerful computer expert in the military, and now the person in charge of the Big Spider system. Colonel Bonev's teacher is the famous Danilov!"

Liu Xiao hurriedly stretched out his hand, Danilov's senior apprentice, he didn't dare to despise it, "Fortunately, fortunately!"

"Mr. Liu, please!" Bonev didn't seem to be good at being polite, so he directly led Liu Xiao into the door, "We are ready, you can visit as much as you like, and you are welcome to comment on our big spider system!"

"Don't dare, don't dare!" Liu Xiao said politely and followed Bonev in.

"This is the core area of our big spider system, the center of the anti-virus system, right here!" Bonev led Liu Xiao into a spacious computer room, where many people were busy in front of the computer, "In the past fifteen years, there have been no major changes to the big spider system, but the technical core of the anti-virus has been upgraded three times. In fact, when it comes to the core technology of anti-virus, whether it is signature code search or active defense, everyone's concept is similar, and whether an anti-virus system is successful mainly depends on whether its architecture is reasonable. In this regard, the Great Spider System is the most successful one!", said Bonev, with a proud face.

Liu Xiao nodded, "The fact that the big spider system can not be eliminated for fifteen years has proven this!"

"Is the Soft Alliance sure to surpass the Great Spider System?" asked Bonev, knowing that the military had made up its mind to eliminate the Great Spider System.

Liu Xiao shook his head, "I don't dare to pack tickets, but if this project lets us do it, we will do our best!"

Bonev was very satisfied with Liu Xiao's answer, and said with a smile: "I believe that the architecture of the Great Spider System can be used for another ten years, at least eight years!", Bonev stretched out his finger and gestured.

"The premise is that your technical core is not outdated!" Liu Xiao reminded with a smile.

Bonev was stunned for a moment, and then laughed, "Mr. Liu is right, we already have the plan to replace the technical core for the fourth time, and we have now reported to the military department!"

As soon as Liu Xiao heard this, he knew that Bonev was against the elimination of the big spider system, and Liu Xiao's purpose of coming this time was not to experience this big spider system, he was here for the attack that pierced the strategic level. At this time, seeing that Bonev's tone was not good, Liu Xiao quickly changed the topic, "I heard that someone took advantage of the loophole of the big spider system a few days ago and pierced our policy-level firewall?"

"The problem is that there are some conflicts between the anti-virus system and the policy-level system in terms of the colocation of permissions to the system, which leads to unclear permissions, and it is this that attackers take advantage of this to get into our network." However, we have made changes to the big spider system, and in the future, the permission configuration will be controlled by the strategic-level system, so that the opponent will not have another chance!"

Liu Xiao breathed a sigh of relief, it turned out that this was the case, "Steko's people told me that the attacker was IND?"

Bonev glared at Stepko's man and nodded stiffly, "Yes, it was done by IND!"

Liu Xiao laughed, "Does Colonel Bonev think so too?"

Bonev was a little unhappy, "Why did Mr. Liu ask that!"

"I don't think IND did it, I believe Colonel Bonev thinks so too!" Liu Xiao looked at Bonev.

Bonev's eyes lit up, and then he returned to his normal color, "I don't understand what Mr. Liu means!"

"Hehe, everyone is doing network security, whether it is done by IND, you and I both know very well in our hearts, I came to Russia this time, not for the big spider system, whether I can win the transformation project of the big spider system, I don't care!" Liu Xiao looked at Bonev, "I came here to hear Mr. Bonev's truth, who is the attacker, this is very important to our soft alliance!"

Bonev knew that there was no point in biting any more, looking at Liu Xiao's expression, he seemed to have known that this was not done by IND, and it seemed that he had some evidence, which made Bonev a little curious, but knowing that Liu Xiao's mind was not on the big spider system, it made Bonev feel a lot more relieved, this is a sign of the Russian security man, and it is the hard work of his teacher, Bonev does not want the big spider system to be destroyed in his own hands.

"Don't tell lies in front of real people, since Mr. Liu is an expert, then I don't have to hide it, this attack incident is indeed not done by IND!" Bonev looked at Liu Xiao, "Mr. Liu doesn't know the details of the attack, I don't know what you based on this judgment?"

"Because there is no need for IND to do this!" Liu Xiao replied.

"There's no need to do this, there's no need to do this...... "Bonev said this sentence twice, and couldn't help laughing, "IND really doesn't need to do this, this one reason is enough! Mr. Liu, please come with me!" After Bonev finished speaking, he led Liu Xiao out of the computer room, walked around in the corridor, and finally entered a small laboratory, which only had five or six computers. These computers are the computers that the other party attacked at that time, and we have not changed the data in them at all, if Mr. Liu has any doubts, he can check it himself!"

Liu Xiao was overjoyed, he didn't expect Bonev to be so easy to speak, and it seemed that the set of words he had prepared in advance was useless, "Thank you!", Liu Xiao said thank you, then came to the computer, and called up the computer's attack data and logs, just a moment later, Liu Xiao laughed, "I was just guessing before, but now it seems that this is really not done by IND!"
