Jin Youcheng's information Li Kaiwen found out all about it when he invaded the Agricultural Cooperative Bank, otherwise he would not have come to see Jin Youcheng in a grand manner.

Wait for the real meeting to realize the error between the network and reality.

The head of the IT department of Nonghyup Bank was slightly shorter than he expected, with a round face and a slight baldness, and the bags under his eyes that could not be concealed looked very tired.

It seems that the position of the head of the IT department is not easy to sit in.

"Hello Director Jin Youcheng, I am KevinLee Li Kaiwen, who made an appointment with you before. Li Kaiwen quickly looked at Jin Youcheng and opened his mouth to introduce himself.

Jin Youcheng's knowledge of Li Kaiwen is only an email from a strange hacker, saying that he is a student studying in South Korea, and he doesn't know anything about the rest of the information.

I made an appointment with him on the phone to meet at a time, and had a brief chat, and I heard on the phone that the boy was not speaking quickly, giving people a very calm feeling.

Li Kaiwen's first impression of Jin Youcheng was that his student spirit was very weak, and he didn't look like a pure student.

Of course, if it is true that he has the same level as the hacker who hacked into the Agricultural Cooperative Bank, he is not destined to be an ordinary student.

That's talent, a big talent, a talent that even the Korean government is looking for.

Jin Youcheng got up with a smile on his face to greet him, "Ah, Li Kaiwen XI is really a hero out of a young man, welcome, welcome." ”

Li Kaiwen bowed down and said, "Director Jin has won the award, just call me Kevin." ”

Jin Youcheng stepped forward and patted Li Kaiwen on the shoulder affectionately, as if Li Kaiwen was a subordinate who had followed him for many years.

"Kevin, I received the email you sent, the loophole of using telephone banking to change the password of the fund account is indeed unexpected by us, and the loophole that even your master was not aware of was discovered by you. ”

Kim You-sung stared at Li Kaiwen as he spoke, observing his expression and reaction, and frankly said that he was very curious about the strange hacker who single-handedly broke into Nonghyup Bank, but unfortunately he didn't have the time or ability to track down his identity.

Since this Kevin Li in front of him is an apprentice of a strange hacker, of course he hopes to find some useful clues from this boy, not for anything else, just for his own curiosity.

The vulnerability of changing passwords and email addresses in email addresses, the last four digits of credit cards, and the phone banking of Nonghyup Bank is not even noticed by engineers in the bank's cyber security department.

Because network security engineers are shield thinking, while hackers are spear thinking, finding all vulnerabilities and then choosing the most direct and effective way to invade the system, even the slightest vulnerability can be turned into a lethal weapon for hackers.

This loophole is simply not worth mentioning for Li Kaiwen, and the loss to the bank will not be very large, and this loophole shows his powerful attack method is the intention that Li Kaiwen deliberately kept and sent to Jin Youcheng as a student.

The recommendation of a hacker who invades the system network alone is not enough to prove his worth, and only by showing his true strength can he win the favor of Jin Youcheng.

Li Kaiwen smiled slightly, "I'm just helping Director Jin pick up the gaps, the network security of Nonghyup Bank can be called a barrier under the auspices of Director Jin, and I found that it is just a small vulnerability that is not worth mentioning." ”

Jin Youcheng said with a smile: "It's not worth mentioning to you, but it's very important to the bank's network security." ”

"Sit down. ”

Jin Youcheng casually pointed to the black sofa in the office, and instructed the secretary to make two cups of coffee and bring them in, apparently planning to have a deep talk with Li Kaiwen.

Jin Youcheng has not doubted Li Kaiwen's true identity, and his identity as a Chinese student is very doubtful.

Almost every time a North Korean hacker group invades South Korea, it will use China's IP address through China, and many times South Korea's fresh security department will mistakenly believe that it is Chinese hackers who attacked South Korea, and the South Korean media is even more hyped up the remarks that Chinese hackers have invaded South Korea.

It's a big black cauldron.

Kim Youcheng is also Korean, and he is not immune to the influence of public opinion, and when he heard that Li Kaiwen was a Chinese student, he thought he was very powerful, because the media always reported that Chinese hackers were very powerful.

Even in the movie, it is mentioned that there is a line in "New World" that says: as long as Chinese hackers are willing, they can get the classified documents from the White House within two days.

Of course, the movie is based on reality that is higher than reality, and it is not difficult for Li Kaiwen to hack into the internal network system of the White House, but he does not dare to package the ticket and say that he can do it if he wants to steal the designated text.

This shows that South Koreans fear and respect Chinese hackers.

Li Kaiwen calmly replied to Jin Youcheng one by one, before coming to see Jin Youcheng, Li Kaiwen thought of a whole set of rhetoric, slightly revealed a little details of his invasion of the National Security Agency and the CIA, disguised as a cooperative operation with his own unwarranted master, and took Jin Youcheng into the ditch, making him convinced that Li Kaiwen, the master of hackers, was the top hacker in the United States.

Jin Youcheng originally wanted to take Li Kaiwen's words, but he asked him about the identity of his master, but he didn't expect him to take the initiative to say it, and he was willing to confess to himself about such a thing as invading the US security services, which showed that he had no reservations and trusted himself, which made Jin Youcheng very excited.

After a detailed discussion with Li Kaiwen, Jin Youcheng overturned his idea, Li Kaiwen is really too quiet, and the hacker who aggressively controls one qiē on the Internet is like two people, he really can't connect the polite student with the powerful hacker on the Internet.

It cannot be ruled out that this kind of quietness is a disguise, but Jin Youcheng is more inclined to believe that the hacker who invaded is an American hacker, and from his methods and behavior analysis, it is more like the practice of American cowboys.

Of course, the American hackers are more powerful than Chinese hackers, there is no doubt about it.

Kim You-sung was convinced.

The South Korean government can spend 2.9 billion yuan to select outstanding talents from all over South Korea to train white hackers to strengthen the security force of the Ministry of Information, Nonghyup Bank is a commercial bank, not a government agency, and there is not enough talent reserve, and having Li Kaiwen, a high-level white hacker from China, joins Nonghyup Bank, which is a great benefit to the bank's network security.

Jin Youcheng immediately hired Li Kaiwen, and he couldn't wait to let him start working immediately.

Li Kaiwen said that he is still a student at the moment, and he needs to explain the situation to the school, and he can only officially start working after the arrangements are made thoroughly.

Of course, Jin Youcheng agreed, this is not an excessive request, he is also afraid that Li Kaiwen will run away, you must know that with his hacker level, he is afraid that the major banks in South Korea will break their heads.

"Let's go, I'll take you to meet our security team. Now that Li Kaiwen agreed to work for Nonghyup Bank, Jin Youcheng's tone changed and he treated him as an employee of the bank.

Most of the employees in the IT department of Nonghyup Bank work in the computer room in the basement, and several key members of the security team work on the 12th floor of the building. There are no special affairs, there are not many staff on the entire twelfth floor, and the work area where the security team is located is not far from Kim Youcheng's office, just in the southwest corner.

"For a moment, I'd like to introduce you to our new member, Kevin Lee, who will be joining our security team. Walking to the southwest corner of the work area, Jin Youcheng clapped his palms to attract the attention of a group of busy staff and said loudly.

Li Kaiwen glanced at it, and seven or eight men in white shirts stood up and gathered together, none of them were very old, and there was a foreigner with a beard and blond hair, and another tall young man was also conspicuous in the crowd.

Kim Youcheng introduced Li Kaiwen one by one, the blonde foreigner named Jones, who is not an employee of Nonghyup Bank, but an employee of IBM, the bank's network architecture outsourcing company, who is responsible for communication between the two sides.

The tall young man's name was Oh Sang-gyu, and he was a master's student majoring in computer science at Sungkyunkwan University.

Before the introduction was finished, Jin Youcheng received a call from a deputy supervisor and walked away two steps to listen to the report of his subordinates.

As soon as Kim You-sung, who was in charge, walked away, the atmosphere was obviously much more relaxed, and the security department was a bunch of people engaged in technology, which could be said to be the elite of the entire Nonghyup Bank, and there were not too many twists and turns between each other.

Wu Shangjiu looked at Li Kaiwen who was too young, and asked with a smile, "Fresh graduates?"

Li Kaiwen shook his head and said: "Dongguo University, 2010, has not graduated yet." ”

Wu Shangjiu was slightly surprised, "Dongguo University, what major are you?"

You must know that the most famous and powerful faculty in Korea are the three universities of Seoul University, Yonsei University and Korea University, which are collectively called "SKY" and are known as Korean universities by Koreans.

Among them, the strongest universities in science and engineering, especially computer science, are Sungkyunkwan University and Hanyang University, and Dongguk University is famous for its art department, but it is not strong in science and engineering, so Wu Sang-gyu was surprised to hear that Lee Kai-won is a student of Dongguk University.

"Faculty of Economics. ”

"Department of Economics?" Wu Shangjiu almost wondered if there was something wrong with his ears, and it was ridiculous that a student of the Department of Economics of Dongguk University wanted to join the bank's network security system team.

The rest of the staff who heard the conversation between the two all shook their heads, although Jin Youcheng has a reputation as the head of the IT department, and they will not question his decision in person, but it is really messy to let the students of the economics department join the security team, and it is completely a backdoor relationship.

The disapproving expressions of a group of staff Li Kaiwen looked at them one by one, and his heart suddenly became angry, NND, when Lao Tzu invaded the Agricultural Cooperative Bank, you rice buckets didn't know where to draw a circle, and you were embarrassed to question Lao Tzu's ability.

Of course, Li Kaiwen can only slander him, and the matter of his invasion of the Agricultural Cooperative Bank cannot be leaked, otherwise it will be a big trouble to be settled by the Autumn Queen, let alone the job is not guaranteed.

Anyway, in the future, there will be an opportunity for you to see my Li Kaiwen's methods, so I will let you be proud for a while for the time being.

Jin Youcheng came over after talking on the phone, saying that he was going to the computer room and took Li Kaiwen to visit by the way.

"Director," Wu Shangjiu strode towards Jin Youcheng, "our team happens to have a problem unsolved, and since this Kevin Li is about to join our security team, I hope he can contribute to the team to help the team solve this problem." ”

"Well, what does Kevin think?"

Of course, Jin Youcheng could hear Wu Shangjiu's sudden repulsion, and he also hoped to see Li Kaiwen's true level in his heart, and did not stop Wu Shangjiu's provocation.

"I'm more than happy to contribute my talents to the team. Li Kaiwen raised his eyebrows.

"Good. Kim Youcheng nodded approvingly.

Wu Shangjiu is afraid that ordinary questions will not be difficult for this Li Kaiwen, and it is a problem with a super high difficulty coefficient, of course, it is not the problem of Nonghyup Bank, but the discovery of Google's ChromeOS vulnerability.

Google has set up a prize pool of up to $3.14 million for Pwnium3, with the maximum individual prize amount of $150,000.

All the members of the security department of Nonghyup Bank, including Wu Shangjiu and Jones, have tried, but to no avail of discovering ChromeOS vulnerabilities, Wu Shangjiu just took advantage of this big problem to test Li Kaiwen and make him lose face.

Jin Youcheng remained silent, he also knew that this was a difficult problem, and Li Kaiwen might also return in vain, after all, Google's security team engineers are not vegetarians, and at the same time, he wanted to take this opportunity to see Li Kaiwen's real materials to see if he could create surprises.

Even if it fails, there is nothing to be frustrated, Kim Youcheng is ready to talk about the scene, and there is no shame in losing to Google's team of professional engineers.

"No problem. ”

Kevin Li replied briefly, walked to the workbench with a solemn expression, touched the keyboard with both hands, took a deep breath, and his brain began to work at high speed.

It's an indisputable fact that all systems are vulnerable. The loophole is there, and Kevin Lee just needs to find it.

Everyone stopped what they were doing and leaned behind Li Kaiwen to watch, especially the American Jones and Sungkyunkwan University top student Wu Sangjiu, who got close to each other, but they tried many times and found loopholes to no avail, just with this young university student, don't joke.

Kevin Li seemed to have returned to his green days when he was obsessed with StarCraft, and at that time, many people crowded behind him to watch his operation, accompanied by exclamations and whispers from time to time, this feeling was really good, making his blood boil and his nerves were extremely excited.

As the minutes ticked by, the entire twelve-story building was quiet and only the sound of keyboard tapping could be heard, and Kevin Lee's fingers fluttered as lightly as a pianist playing music, full of rhythm.

"Smack. ”

After a heavy press of the enter key, all sounds stopped abruptly.

Li Kaiwen took a long breath, got up leisurely, and asked Wu Shangjiu: "I don't know how much reward Google will give if I find a ChromeOS vulnerability?"

Wu Shangjiu subconsciously licked his lips and said, "Forty thousand dollars." ”

"That's a lot of money. ”

Jin Youcheng looked excited, "You found out?"

"Ah, it's a bit troublesome, it took a little time, and Director Jin waited for a long time. ”

"No trouble, no trouble. Kim Youcheng rubbed his hands excitedly.

Kevin Li really discovered the vulnerability of ChromeOS, which is really not covered.

Jin Youcheng subconsciously glanced at the time on his wrist, and in four and a half minutes, it didn't even take five minutes to find a vulnerability that made his security team helpless.

I've really found a treasure.

"Kevin, I'll take you to the underground computer room to visit, we have a total of 553 servers in Nonghyup Bank......" Jin Youcheng and Li Kaiwen walked side by side, looking eager, and began to explain endlessly.

Until Jin Youcheng and Li Kaiwen took the elevator to leave the twelfth floor, Wu Shangjiu still couldn't believe that this guy actually found out, actually found out, actually found out. He tried his best, and all the members of the security services tried so hard that they didn't find out, and he found out.

What a failure.

The blonde American Jones was closest to the computer, and after Kevin Lee left, he grabbed the seat as soon as he left, quickly checked the steps he had taken to find the vulnerability, and nodded his head as he watched.

"Awesome. ”

"How did he do that?" asked the crowd in the periphery, the monitor so big that the people in the back could only look at the back of their heads.

Jones pointed to the monitor and explained, "He connected the ChromeOS video parsing, the Linux underlying system, and the error in the configuration file to form a vulnerability. ”

"It turned out to be possible to do this. Wu Shangjiu suddenly realized.

Jones exclaimed, "This guy really can't be underestimated. ”

"Sure enough, it's a Chinese hacker. The crowd didn't know who said it, and everyone present nodded almost unanimously in agreement.

Chinese hackers, in the hearts of South Koreans, are cattle and deeply rooted.
