"We can't drink alcohol in this underground base. Jiang Yi said helplessly: "You still drink something else!"

"Whatever!" Yun Zhan shrugged his shoulders and didn't care, anyway, he didn't really want to drink, he just broke away from Jiang Yi.

Jiang Yi went to prepare for a drink, and Yun Zhan also turned on the computer, of course, not to study the traces of human invasion in various systems of Longmen, but to remotely connect to Mo Zhilin's computer, and she would take care of everything.

After a while, Jiang Yi put a cup of hot coffee on the desk and asked, "How is it?"

Yun Zhan raised his head and asked without answering, "What did your people find?"

Jiang Yi smiled bitterly and said, "There is no record in the log files of Linx, and the rapper also does not record any signs of hackers' activities, so it is certain that these hackers are real masters." ”

"That's for sure!" Yun Zhan asked with a smile, "Are there any traces left by hackers in the firewall?"

It seems that Yun Zhan seems to understand the same thing, but in fact, it is not, because he has put a miniature communication device in his ear, which is developed by Mo Zhilin, which is a unique communication device of the Yun family, and it is difficult for outsiders to find it when placed in the ear, and Yun Zhan can not only hear the people on the other end, but also the people on the other end can also hear Yun Zhan and the people around Yun Zhan, so Jiang Yi asked, Mo Zhilin has already taught Yun Zhan how to speak.

Jiang Yi shook his head helplessly and said, "No! Obviously, these hackers have bypassed the firewall." ”

Yun Zhan raised his eyebrows and said with a smile: "Are you so confident in this firewall of yours? Is it just that it was bypassed by hackers, not breached?"

"Breaking through the firewall, is this difficult?" Jiang Yi looked at Yun Zhan with some doubts.

Yun Zhan smiled: "It's really difficult, but don't you also say it? These hackers are real masters." ”

"What do you mean?" Jiang Yi frowned, and said in a hurry: "Could it be that the hacker has ......?"

Yun Zhan waved his hand and said, "Hmm...... The fire-resistant logs have been deleted by hackers. ”

Although it felt a little incredible, Jiang Yi also knew that the firewall was not impossible to breach, and its logs could also be deleted and modified.

And she also knew that attackers could also launch denial-of-service attacks on firewalls, crippling or at least slowing them down, making it difficult to respond to attacks in a timely manner, compromising the integrity of firewall logs.

"What do we do now?"

"It's okay!" Yun Zhan smiled very negotiably, and then put his eyes on the computer screen, his finger just pressed the enter key, and there were already numbers flashing out on the computer screen.

Yun Zhan didn't do anything more, and after a few minutes, he looked up and smiled, "The firewall logs have been recovered." ”

"Recovered?" Jiang Yi walked behind Yun Zhan in disbelief, and then leaned over to look at the computer screen.

After seeing the content on the computer, Jiang Yi exclaimed: "Ah...... All of the hacker's activity in the firewall is restored, how do you do that?"

Yun Zhan raised his eyebrows and said coquettishly: "Military secrets!"

"Uh......" Jiang Yi was quite speechless, this guy was obviously taking revenge on her for answering the confidential thing just now, it was really enough to be careful.

However, she also learned some of Yun Zhan's behavior styles from Yun Shilin, and she didn't care, but said excitedly: "With this data, we can track down these attackers." ”

"And then?" asked Yun Zhan, squinting his eyes.

Jiang Yi may have been overexcited, and without thinking about it, he responded: "If you find their IP address, you can find them in reality, hum...... Dare to steal the secrets of Longmen, and he must be made to pay for it. ”

"Uh......" Yun Zhan rolled his eyes and said angrily, "If the IP address is not in Europe, how do you bring them to justice?"

Cold water was splashed, Jiang Yi finally came to her senses, and responded depressedly: "Yes, it is impossible for hackers to use real IP addresses." ”

Yun Zhan smiled and said, "That's right! If it were me, it would definitely be a long-distance and close-range attack. ”

"What do you mean?" Jiang Yi asked puzzled.

Yun Zhan asked, "Do you know about 'jumping'?"

"Know!" Jiang Yi also understood what Xi Jaehao meant.

She knows that before hacking, hackers generally try to control one host on the network, exploit the vulnerabilities of the operating system to obtain system privileges, and then use this as a basis to access other hosts on the network, which is often called "jumping" by hackers.

Normally, hackers tend to jump like this several times before reaching the target host.

For example, a hacker in the Americas may log in to a host in Europe, log in to a host in Africa, jump to Asia, and finally attack the network from a host in Oceania.

In this way, even if the attacked network finds out where the hacker launched an attack on itself, it is difficult for managers to find it back.

What's more, after the hacker obtains the system privileges of a certain host, he can delete the system log when he exits and cut off the "vine".

As a result, it is very difficult to find the hacker.

Jiang Yi also knew that it was difficult to find out the actual IP of the hacker who used this "jumping" method, and said a little depressedly: "Do you just let them go?"

"Let it go?" Yun Zhan couldn't help laughing, and said, "Even if this hacker jumps 10,000 times before he comes in, he can't escape the palm of our hand, so you can put 10,000 hearts!"

"Is it really okay?" Jiang Yi still didn't believe it, of course, she didn't hear the language problem in Yun Zhan's words, Yun Zhan said the word "we", which naturally would not include Jiang Yi, but someone else.

That is to say, the hacker can't escape the palm of his hand is not Yun Zhan's, but Mo Zhilin's, but Yun Zhan shamelessly regarded Mo Zhilin's achievements as his own, fortunately, Jiang Yi in a hurry didn't hear it, otherwise, Yun Zhan was afraid that he would be embarrassed.

"I'll just do it, you better go drink or something, don't bother me here, since you have chosen me, you should believe me!" Yun Zhan said with a wave of his hand.

"Okay!" Jiang Yi nodded, anyway, there was no way for her to find a hacker in this kind of jump invasion.

So pinning his hopes on Yun Zhan, whether Yun Zhan can really find the hacker or not, it doesn't matter, anyway, a dead horse is a live horse doctor.

"What are you still standing here for?" Although Jiang Yi believed in himself, seeing that this woman still hadn't left, Yun Zhan frowned.

"I want to see how you find hackers. Jiang Yi glanced at Yun Zhan, and her voice was very xiao, obviously, she also knew that there was a suspicion of stealing the operation of Yun Zhan in this way, however, although she was also an expert in networking, but cracking the difficult technique of jumping was not something she could master, obviously, the temptation of learning this technique was too great, even if she knew that it was immoral, she wanted to learn it secretly.

"I'm sorry, but it's also a military secret. Yun Zhan glanced at Jiang Yi talkatively, just kidding, this woman understands network technology, once she starts to crack it, won't he be exposed immediately?

He couldn't pretend to be forced anymore, so he could only ask Jiang Yi to go before letting Mo Zhilin start to solve the matter.

Although Jiang Yi was very curious, seeing that Yun Zhan did not give face, she could not do anything, so she could only leave her office depressed.

Seeing Jiang Yi leaving, Yun Zhan also informed Mo Zhilin to start network tracking, which took about fifteen minutes, and it was said that Mo Zhilin used a set of AX-7 language invented by herself to write a tracking program, and put in the action information left by hackers in the system.

Soon, the tracker was up and running.

Well...... It's an auto-tracking program, and after launching, it's all automatic until the hacker's actual IP is found, and there's nothing to do with Mozhilin.

Mo Zhilin had nothing to do, so Yun Zhan was even more boring, so he walked out of Jiang Yi's office, and saw that Jiang Yi was discussing something with several staff members, he pointed at Jiang Yi, hooked it, raised his eyebrows, and said, "Hey...... Come here!"

"What's the matter?" Jiang Yi looked back at Yun Zhan suspiciously.

Yun Zhan smiled and said, "I need beer, you go and buy me a didian back." ”

"I told us we can't drink here!" Jiang Yi said helplessly.

"I'm sorry, I can't help with tracking down hackers, my mind won't be clear without beer. Yun Zhan shrugged helplessly.

"You ......" Jiang Yi gritted her teeth angrily, this guy clearly relied on his skills to show off his might, and when he saw that he had a request for him, he yelled at her, you must know that even if her boss Yun Shilin faced her, she had to be polite, why did this guy point fingers at her and be a slave?

However, even so, Jiang Yi had no way, and if he wanted to find the hacker who invaded the Longmen weapon information system, he couldn't do without cloud warfare.

Those who seek people have to bow their heads.

"Wait for ......" Jiang Yi shook her hand angrily and helplessly.

And the staff of the Longmenluo department looked at each other, when will their heads go to buy wine for a man?

It was so unexpected.

You must know that when you go out from the base at the gate of Longmenluo, you not only have to drive, but also have to take a helicopter to the city to buy it outside the cave.

That makes the cost of beer high, eh...... Much higher than oil.

However, they all admired Yun Zhan, normally, Jiang Yi yelled at them, and now someone finally yelled at the head to drink six, this feeling is still really wonderful.

After an hour, Jiang Yi really returned to the base with a dozen beers, threw the beer in front of Yun Zhan, and said viciously: "Drink you to death!"
