"There's no rush for this!" Sidney looked at Langdon and said slowly, "What do I want?"

Langdon looked at the person in charge, and when the person in charge nodded, he took out a sealed bag from his pocket and put it on the table, "There's a disk here, it's the information you need, but it's only the top half, when we catch the attacker, we'll hand over the bottom half to you!"

"That's fair!" Sidney didn't say any nonsense, and put the sealed bag away, "Now you can go and contact the cyber security department!"

The person in charge stood up at this time and said with a smile: "Mr. Sidney, I will bother you more this time!"

Langdon quickly pulled out his phone and contacted the cybersecurity department, he had to get it done before Sidney could change his mind. The network security department is having a headache at this time, the attackers have been making trouble for several days, not stopping, but becoming more and more arrogant, and if this continues, it is estimated that the people in the network security department will have to get out of class, and now when they hear that the intelligence department invited the famous Sidney over, they can't help but be overjoyed, in fact, they have long wanted Sidney to come, but unfortunately they can't get online, and Sidney is a person who can't get in the oil and salt, and now the intelligence department has invited them, and it's too late for them to thank them, where will there be any opinions, just tell Langdon to bring Sidney directly to the network control center。

The person in charge sent Sidney directly downstairs this time, and watched him leave with Langdon, then he turned around and went upstairs, and the troubles of many days were finally relieved by Sidney's arrival, he believed that Sidney would definitely be able to catch the attacker, if Sidney couldn't do it, then the world really didn't know who could do it.

Arriving at the Cyber Security Center, Langdon revealed his identity and led Sidney all the way to the control hall.

The control center was a busy scene at this time, most of them were busy in front of their computers, and there were a few people, gathered in front of an operating console, discussing something, and the signal corps was shuttling back and forth in the control hall, passing various orders.

Seeing that no one cared about him, Langdon said loudly: "Who is the person in charge here!"

The people in front of the console turned their heads and looked over when they heard the voice, one of them was the colonel who went to the intelligence department for routine maintenance last time, he quickly ran over and saluted, "General Langdon, Colonel Webb reports to you, I am the person in charge here!"

"I'll introduce you!" Langdon looked at Sidney beside him, "This is the famous Mr. Sidney!"

"Hello, Mr. Sidney," Colonel Webb saluted again, "I'm so sorry I couldn't meet you in person!"

"Did anything happen?" Langdon asked, looking at the busy scene in the hall.

"Five minutes ago, there was another serious hacking incident, and we are coordinating it!" Webb replied.

When Langdon heard this, he was nervous, no, could it be that someone was hacked by the intelligence department's machine, so he asked, "What the hell is going on, you can introduce Mr. Sidney!"

"This attack is different from the previous ones, the attacker did not directly attack the ZF website, but changed the domain names of two large websites in China, and directed all the traffic of these websites to the website of the Ministry of Intelligence!" Weber said.

Langdon cursed secretly in his heart, this time it wasn't the Ministry of Intelligence that "hacked" others, it was someone else who attacked the Ministry of Intelligence, this attacker was really boring, "What is the result? What is the current state of the Ministry of Intelligence's website?"

"The Intelligence Department's website has a multi-way backup system, and it hasn't been overwhelmed by the sudden sheer volume of traffic!" Webb said.

Langdon breathed a sigh of relief, "That's good!"

"But ......" Webb frowned, a little embarrassed, "But the website of the Ministry of Intelligence has been tampered with, and the homepage is the same as the previous hacked ZF publicity website!"

Langdon almost vomited blood, which was even worse than before, and it was a joke to get everyone to see the Intelligence Department.

Sidney spoke at this point, "Colonel, do you have any detailed data on the attacks?"

"Yes!" Webb nodded hurriedly, "At the console, please follow me!"

Langdon could only hope that Sidney would find the attacker quickly, and he walked with Sidney to the console's computer.

Webb introduced Sidney to the experts in front of the console, and everyone's eyes were straight at that time, this is a legendary god-level person, a hacker among hackers, his idol, he didn't expect the idol to stand in front of him.

Sidney ignored the strange stares of those people, but walked to the computer, called up the collected attack data, and just looked at it briefly, Sidney shook his head, "This is not a virtual attack!"

"Isn't it?" Langdon was the first to call out, "Mr. Sidney, you ......", Langdon wanted to ask Sidney if he was wrong, but when he said this, he quickly shut up, this Sidney's biggest taboo is that he can't doubt his ability and judgment! All his previous judgments have been proven to be right, only the Black Hat Conference faced the products of the Soft Alliance, and there was only one miss.

Webb next to him also nodded, "A few of our experts were also discussing this matter just now, and the data on the website of the Ministry of Attack Intelligence was obviously different from the data of the previous days, and we were also very puzzled, but we were not sure of our judgment." Now that Mr. Sidney says so, we know it!"

Sidney bowed slightly, "You call up the attack data from the other days and I'll take a look!"

Webb hurriedly stepped forward and called up a few copies of the attack data from the previous few days in a few clicks, "That's it, please take a look!"

Sidney looked at each piece of data for a minute or so, then turned it off, stood up straight, and said, "That's right, these pieces of data are obviously data from virtual attacks. ”

Weber witnessed every operation process of Sidney on the side, but he didn't know what Sidney used to distinguish between virtual attacks and ordinary attacks, because although the data was different, Weber only saw that the attack methods were different, and he couldn't know which one was left by the virtual attack, and these data were no different from normal attacks, but he didn't explain his incomprehension, and Sidney would not necessarily give him an answer. So he asked: "A few days ago, the attackers were using the same attack method, in fact, we all patched it, logically speaking, this attack method did not work, but because he used a virtual attack, it worked." Today's attack is completely different, it seems to be aimed at a vulnerability that we didn't notice about!"

Sidney nodded, "Actually, the previous data itself is useless, the attacker even has a virtual attack method, and the attack method you analyze from the data is completely different from the attack method he really uses." And today's data is the data left by the real attack, there is no fiction, from this data, you can analyze who the attacker is!", Sidney said this, smiled, and said: "Maybe after you debunk the trick of the virtual attack, you will find that the method used by the attacker a few days ago is exactly the same as today's attack!"

Weber realized that virtual attacks are not omnipotent, and he also needs to use a real vulnerability to attack, but he uses virtual means to disguise the real attack methods, "Mr. Sidney, I still don't understand a little, why don't today's attackers use virtual means to disguise?"

"The reason is simple!" Sidney smiled at the corners of his mouth, "because he can't attack virtually!"

"Ahh

Sidney nodded, "It should be like this, as can be seen from the surface of the data, this attacker used a very sophisticated IP cloaking strategy in order not to expose himself, and if he can attack virtually, there is no need to do so." Because no matter how complex IP cloaking is, as long as you trace it carefully, you can still find out the real location of the attacker, but virtual attacks are different, no one in this world can find the slightest information about the attacker in the data after the fact!"

"Wouldn't it be impossible to find the attacker?" Langdon didn't understand what was said, but he could still understand it, and he came to Sidney to catch the attacker.

Sidney raised his hand to interrupt Langdon's words, he knew what Langdon would say next, and said, "I just said that no one can track down the attacker in the data after the fact, but I didn't say that there is no way to track down the attacker!"

Langdon breathed a sigh of relief, he was a little too nervous, so much so that his analytical skills had dropped a lot.

"Mr. Sidney, please give me your orders, and our entire Cyber Security Department will cooperate with your actions and strive to catch that attacker as soon as possible!"

"I'll just do it if I track down that virtual attacker!" Sidney looked at Weber, "I think you better hurry up and find out today's attacker, the previous attacker is not terrible, but the attacker is more terrifying today!"

Webber was stunned for a moment, and then a cold sweat broke out on his back: yes, the purpose of the attacker before was very obvious, that is, to take revenge, but what is the attacker doing today? Isn't it also revenge? He directed the traffic of the portal website with a high degree of attention to the website of the Ministry of Intelligence, and then hacked the homepage of the Ministry of Intelligence, which obviously wanted to fan the flames, for fear that this matter would not make a big fuss, and this person's intentions were inevitably a little too sinister!

Langdon is in the field of intelligence, of course he also understood, and immediately said to Weber: "Hurry up and find an expert to analyze the data, you must find out this attacker, if there is anything that needs assistance, just say, our intelligence department will fully cooperate!"

"Okay!" Weber didn't dare to delay, and immediately said to the experts next to him: "You immediately organize people to analyze the data of today's intrusion into the website of the Ministry of Intelligence and find out the clues of the attackers! As soon as there is news, report it to me immediately!"

However, Webber didn't leave, he said to Sidney: "Mr. Sidney, I'll cooperate with you to track down that virtual attacker, if there is anything that needs to be coordinated, you can just command!", Weber didn't want to miss this good opportunity, as long as he could see a little bit of the way from Sidney's tracking methods, it would also benefit him a lot.

Sidney of course knew Weber's thoughts, but he didn't say anything, because he felt that this Weber was indeed a quick-witted person, which made Sidney like it very much, and he liked talented people, so he said a few more words, "In fact, there is a difference between virtual attacks and virtual attacks, and I didn't understand this truth before, but later after the guidance of Mr. Liu of the Soft Alliance, I figured out the mystery of this." Take this guy who attacked you this time, for example, he is just getting started, and the deliberate virtual exposure of his shortcomings, such attack data allows the insider to see that it is a fraud at a glance, so it is not difficult to track this kind of person, as long as he launches an attack, I will have a way to know. But if you run into those real virtual attack masters, it will be very difficult to track them, their methods are ever-changing, and even the switch between attack and defense will occur in an instant!"

"Mr. Sidney must be one of those masters!" said Webb.

Sidney shook his head twice and said with a smile: "At most, I have just touched the door, if you want to talk about the master of virtual attacks, it must be Mr. Liu of the Soft Alliance!"

Langdon muttered a little in his heart, fortunately, the person who attacked this time was not Liu Xiao, it was Liu Xiao who was going to be replaced, and this Sidney's technology was still pointed out by Liu Xiao, and he wanted to rely on Sidney to catch Liu Xiao's tail, I'm afraid it would not be realistic. But the Ministry of Intelligence didn't offend other Chinese hackers, especially super hackers, so who is this entangled hacker master?

Sidney pulled out a small disc from his suit pocket, "You go and install the software on this disc to the server that could be hacked, and if he attacks these servers again, I will have a way to track his whereabouts!"

Webber was overjoyed, and quickly took the disc, "I'll arrange it!", after speaking, he walked away as if holding a baby, this is a good thing, with this thing, in the future, his network security department will not have no way to take those virtual attackers.

Sidney put his hands in his pockets and looked at Langdon, "What are you thinking?"

Langdon shook his head, "No!"

"There's something I don't understand, and I was about to ask you!" Sidney paused, "Why would your Intelligence Department suggest that the Department of Defense abandon the Soft Alliance's policy-level firewall?"

Langdon looked at Sidney in surprise, even Sidney knew about this, and now there are more and more secrecy methods, but the news can't be held at all, Langdon coughed, "Didn't the Ministry of Defense say it?

Sidney snorted through his nostrils, "Forget it, you don't want to say, I won't ask." It's just that I have a message that I hope you can convey to your generals. ”

"Mr. Sidney, please speak, I will tell you!"

"Don't mess with hackers, especially hackers like Mr. Liu!" Sidney stared at Langdon seriously, "You don't know how serious the consequences of that would be!"

"Hehe!" Langdon smiled to hide, "I'll tell you!"

"Okay, you don't have to stay here with me!" Sidney turned to look at the flickering data on the computers on the console, "You go about yourself, remember to get the information I need!"

After Weber sent someone to install all the software, he hurried back to the control hall and walked behind Sidney, "It's all installed, Mr. Sidney!"

Sidney nodded, "Good!", and walked over to a vacant computer, "I want to requisition this computer!"

"No problem!" said Weber, "what more could you ask for?"

"No!" Sidney sat down in front of the computer, took out a small disc from his pocket, stuffed it into it and installed it, and as soon as it was installed and run, the interface of the software showed the operation status of dozens of servers, which were the ones that Webb had just sent someone to install that could be attacked.

Weber was disappointed, no wonder Sidney was so relieved to hand over the software to himself to install, it turned out that there was another mystery, the program just installed was just a client, and it had to rely on the server-side control program in Sidney's hands now to monitor and track the situation of the virtual attacker, only the client, it was equivalent to a piece of waste.

Maybe it was today's unexpected attack that confused the virtual attacker, Sidney guarded for a day, and did not wait for the other party's attack, and it was the first time that the network of country F had such a long time of peace these days.

Weber also had to look at Sidney differently, at first he saw Sidney have to go to a five-star hotel to book, make a special car to send it, and the water he drank was also brought by himself, so he thought that Sidney must not be able to survive, but he didn't expect that in the end he couldn't stand it anymore, and sat there and dozed off, but Sidney always sat in front of the computer and didn't move, just took a book, read the book, and glanced at the computer.

The next morning, Langdon came, came in, greeted Sidney, and asked Webb, "How's it going?"

Webber rubbed his face before he drove away the sleepiness a little, "That attacker didn't come to attack yesterday, and he stayed all night!"

Langdon frowned, and then walked behind Sidney again, "Mr. Sidney, why don't you go and rest for a while, and we'll call you again if there is a situation!"

Sidney put down the book, stood up and moved his muscles, "You calculate for me, at this point, what time should China be?"

Langdon calculated slightly, "It's not dark yet, but it's coming!"

"Oh!" Sidney thought for a moment, "then keep an eye on it for a moment! I've looked at the previous attacks, and most of them were launched after dark!"

"Do you think you need anything?" Langdon asked, thinking that Sidney was really dedicated, and that he was really responsible for what he had promised.

"No need!" Sidney waved his hand and walked to the window to look at it for a moment, then returned to the computer and sat down to continue reading.

Langdon was also bored, pulled up a chair, and sat side by side with Webb behind Sidney, talking about some ideas for the future of cybersecurity.

After about another hour or so, Langdon said what he should have said and what he shouldn't say, and he really couldn't find any topic, so he was about to say goodbye, he stood up, opened his mouth and just said the word "Sidney", and the computer in front of Sidney screamed.

"It's coming!" Sidney glanced at the screen, then put down the book in his hand, turned and pulled out the keyboard, ready for the next step.

Weber also came to his senses, stood up on the ground, approached the computer, and when he looked at it, he saw that among the dozens of computers, there was a computer logo flashing around, issuing a red alert, "This is the president's website!", Weber is too familiar with the addresses of these servers!

Sidney double-clicked on the logo of the president's website, and the software interface immediately switched, and the data was constantly refreshed, and a master like Webb was also confused. However, the information box below shows what the data represents.

"It's a virtual attack!And the source of the virtual attack happens to be the machine from your intelligence department!" Sidney nodded, "Looks like this is the person you're looking for!"

"So what now?" Webb was a little anxious.

"My software has started tracking analysis!" Sidney smiled slightly, "Don't worry, as long as the other party is still online, my tool can analyze his real location!"

Langdon looked at the screen as well, and he could read the results of the analysis displayed at the bottom of the screen.

"Disassembling the virtual data packet!"

"Virtual parameters are being analyzed!"

"The data packet has been disassembled, and the parameters are being ......"

"The real attack vector has been identified, and the real data packet ...... is being restored"

"Restoration completed, disassembling ......"

Langdon could see that the sweat came out, this has to be unpacked a few times, he looked at the time, the other party has been in the server for more than ten minutes, and may leave at any time.

"Didi!" suddenly another alarm sounded.

Sidney quickly switched the interface and found that all the servers were normal, only the server of the presidential website was flashing around, Sidney was a little puzzled, and he didn't suffer any other attacks, why did the software call the police.

When he switched to the data analysis interface again, he saw that the progress of data analysis had returned to 92 percent, but now it had returned to 50 percent.

"Strange!" Sidney had encountered this for the first time, he had tested the tool a few times since it was designed, and there were no problems, but he had never encountered any other virtual attacks, so he couldn't be sure if it was a software glitch or something that had happened.

"What's wrong?" Langdon asked.

"Nothing!" Sidney waved his hand to calm himself, maybe it was just an error in one of the software's data displays, no fuss.

The attacker never left, only listened to the sound of "ding", and the data analysis showed that the completion rate was 100%!

But when they saw the results of the analysis, Webb and Langdon were taken aback at first, because the information box clearly stated: The attacker's real location has been locked, the server of the Intelligence Department of Country F, and the IP address is: 112.125.214.12

Langdon almost vomited blood, isn't this still the computer in his own department, analyze and analyze, why is it still this computer! I found Sidney by myself, just to catch the real attacker and clear the suspicion of the Intelligence Department, who knows that Sidney helped prove that it was the attack launched by the Intelligence Department.

"No, no!" Sidney stood up, and after a moment, added, "I know, I know!"

"Mr. Sidney, what the hell is going on?" Webb was stupid.

"There are two attackers!" Sidney was very excited, "we were going to catch the first attacker, but just as we were about to catch him, the second attacker came, and it was clear that he was a master of virtual attacks, because he successfully dug the attack data of the first attacker." It's amazing, it's amazing!", Sidney exclaimed, "So virtual attacks can do this!"

"Mr. Sidney, look!" Webb suddenly noticed a change in the computer screen.

Sidney looked down and was also shocked, his software had disappeared, and there was only one line of English letters on the screen: "It's not something you can do, Sidney!"

"Three!" Sidney cried out again, "it's three attackers!"
