Full-level boss is not easy to chase

Austria.

Xia Da was in a state of desperation, circling around in the office, staring at the sent email messages.

The phone rang, and a strange call came.

Xia Da picked up the phone and breathed a sigh of relief: "Boss, the situation is urgent and you must do it."

"I read the information in the mailbox. After class, I bought a computer and started working." Xia Chu played with the headphone cable and listened to the movement outside the door.

"You have to be careful, the hackers used the official IP address of a middle school in your country to control the behavior of those students through the network, but this matter is handed over to the person in charge of your security organization, boss, you draw it as soon as possible Give the portrait of the criminal to the person in charge over there."

"Do you know what middle school it is in China?"

"The high school attached to the Academy of Fine Arts."

Xia Chu paused for a moment, lowered his voice: "Did the hacker take action last time?"

Xia Da over there said regretfully: "Boss, you are being targeted, we can't find out who it is, and we don't know what methods they will use to deal with you, but don't worry, your side is a society ruled by law. , and they dare not act blatantly."

"Cut!" Xia Chu was silent for a few seconds: "Is this a big transnational case?"

"Don't worry, you'll be fine." Xia Da was still reassuring her.

"After I'm done, can you apply for a capital account for me?" Just when Xia Da thought that the other party would hang up on him as usual, he heard Xia Chu's request.

"Are you sure?" Xia Da smiled, picked up the chewing gum on the table and threw it into his mouth: "You can only apply for a permanent residence in the capital in the name of a full member of the International Security Organization. In the past, you would rather be hired. How did you change your mind now?"

"Class is about to start, I'm hanging up." Xia Chu didn't bother to satisfy Xia Da's curiosity, raised his brows and eyes slightly, hung up the phone, opened the bathroom door and walked out.

School medical room.

"Brother Yu, this is senior Yang Yi, who graduated from Peking University majoring in computer science and now works in the National Information Center. Principal Leng introduced him. Senior Yang Yi is responsible for the network security of the high school attached to the Academy of Fine Arts."

Yang Yi was a year older than Gu Xu and Luo Yu, and stayed at the National Information Center of the Chinese Academy of Sciences after graduation. He was a top student majoring in computer science.

"Young Master Luo, I have admired your name for a long time."

Yang Yi's temperament is gentle and elegant, with a pair of clean hands with long and strong fingers. When shaking hands with Luo Yu, there was a thin layer of hard calluses, and the black-rimmed glasses could not hide the intelligence in his eyes.

Both went to Peking University, and Luo Yu's reputation was overwhelming. The two met on campus, but they didn't have much contact with each other.

He was born ordinary and was not from the capital city. He just heard from his classmates that Luo Shaoshi has a special background and is not a person in the capital circle that ordinary people can approach.

Yang Yi brought his own computer and USB flash drive.

"I hope to find the person who hacked into the campus network of the attached high school during these two times and used the campus network to send messages on the comic festival forum." Luo Yu briefly turned on his computer and motioned to Yang Yi to read the information.

Seeing the photos of the tragic deaths of young men and women on the materials, Yang Yi's heart trembled. Luo Shao's background was indeed mysterious, and he was actually investigating the case.

What Yang Yi checked was the IP address that sent the message. Sitting at the desk, he began to enter a series of codes, and piles of incomprehensible data were arranged on the black screen of the computer.

For a long time, his eyes fell on one of the strings of codes. After thinking about it, his fingers quickly entered a string of codes.

"Fire Dragon Firewall, it's Fire Dragon Firewall?" Yang Yi stared at a string of codes in surprise, and tapped his fingers again.

"Senior Yang, what is the fire dragon firewall?" Gu Xu looked curiously at a string of unrecognizable letters on the computer.

"It suddenly appeared on the Internet a year ago. It once broke through the security firewalls of major websites and caused panic. However, it only appeared for 5 minutes. After 5 minutes, the Huolong Firewall disappeared mysteriously."

Yang Yi was full of admiration: "Later, someone on the forum said that it was a prank by a hacker. Someone took a screenshot, and the last code name of the firewall was DL."

"Then the network of the attached high school was attacked by this man named DL?"

"Not necessarily." Yang Yi shook his head: "It has been found out. The hacker who broke into the network of the attached middle school set up two fire dragon firewalls by himself, and sent a message with the help of the P website in the attached middle school. However, these two fire dragon firewalls have been erased. , the Fuzhong network has returned to normal, and I can't find the real IP address of the hacker."

Yang Yi stopped, seeking truth from facts: "A year ago, the Huolong Firewall appeared for 5 minutes and disappeared mysteriously, which aroused the attention of major websites. The website spent a lot of manpower and material resources to learn and crack it. As far as I know, many experts have already learned it. Set up the Huolong firewall, so it is not necessarily the first DL to commit crimes."

"Senior Yang, how do you determine that it's not DL?" Gu Xu carried forward the spirit of breaking the casserole and asking the end.

"The IP address is wrong. Later, some hackers finally cracked the Huolong Firewall. The URL was sent by a computer playing games in an Internet cafe in a small town. It is said that the customers of that Internet cafe are minors from a nearby village. They even failed the English test. How could that be possible? Is there a master who designed a firewall? Later, some people speculated that it was the work of the world's top hackers, and it did not cause any losses, so it became an unsolved case in the computer industry."

Obviously, Yang Yi was also very concerned about the emergence of Huolong Firewall a year ago, so he explained the cause and effect.

"You mean that the hacker who sneaked into the middle school used the Huolong Firewall protection to erase his traces of action?"

"It hasn't been completely erased, the network imprint of the Huolong Firewall is still there, but..." Yang Yi raised his head and looked at Luo Yu who was in deep thought: "The person who wanted to restore the last disappeared imprint of the Huolong Firewall was not the one who wrote the code of the Huolong Firewall in the first place. DL is not acceptable, only DL has source code.”

"Has your computer industry not found any traces of DL in the past year?" Gu Xu was thoughtful.

"No, suddenly it mysteriously appeared on the entire network for 5 minutes and then disappeared mysteriously. All the networks in the world were hacked without any loss. The computer industry took that DL as a prank, and tacitly regarded DL as a hacker who is both good and evil. .”

"The hacker who committed the crime was either DL or an admirer of DL." Yang Yi came to a conclusion and stood up: "Young Master Luo, Gu Xu, I can only help you two so far. I have set up a triple firewall on the network again, this time if the hacker still uses his brains, there will be a network alarm device, and the hacker will not be so easy to succeed for at least an hour."

After sending off Senior Yang, the medical room was silent for a while.

"Brother Yu, what's the next step?"

"Two prongs."

"Why do you have a two-pronged approach?" Gu Xu felt that he could not keep up with Luo Yu's IQ.

"Keep up with further investigations by international security organizations. On the other hand, ask the hacker alliance to offer a reward to someone who can crack the source code of Huolong Firewall."

"Looking for DL?"

"Ah."

"Brother Yu, are you sure the medical room doesn't recruit an hourly assistant?" Gu Xu appointed him to organize the medicines. After all, he is also the eldest son of a medical family, so how could he work as a nurse and handyman.

"Trick." Luo Yu glanced at Gu Xu, cherishing words like gold.
