There are two kinds of hackers in the world, one for profit and the other for entertainment.

————————————————

"Didi, Didi", a rapid electronic alarm sounded from the 28th floor of the Merk Union Building, and the staff of the scientific research room stared at the computer screen, crackling and typing on the keyboard, like a group of vigorous soldiers, guarding their own territory in the network.

Ten minutes before the alarm went off, a man rushed into an office, looking panicked.

"Mr. He, no, the A8 system has been hacked"

"Tell me slowly, what's going on?"

"Well, you can go to the research room and have a look, Dr. Liu, they are all there. ”

Mr. He's name is He Ying, who returned from studying abroad a year ago and served as the president of the Moke trade union, and his father, He Hongsheng, is the chairman of the trade union. He Ying has a beautiful face and long hair, which is simply the best of the best, especially a pair of slender jade legs, and his body trembles slightly when he walks, and there are many admirers.

He Ying put down the document in his hand and followed the man to the scientific research room quickly. Inside, a group of researchers were surrounding a middle-aged man with white hair. Seeing that Mr. He was coming, the surrounding staff hurriedly got out of the way and returned to their positions.

"Dr. Liu, what's going on?"

"That's right, this morning I found that there are more than 300 gigabytes of system logs than usual. After checking, it was generated by someone who was constantly cracking the login password last night. And in the end, it shows that he managed to get in. Dr. Liu said to He Ying beside him, and then turned his head with a puzzled expression, "But it's strange that after he came in, he didn't do anything else, and he didn't detect the planting of the Trojan horse." ”

"Nothing has been done? What about the data?"

"I've also seen the data, it's still there, and there is no trace of copying"

He Ying bit her pink lip lightly, her brows furrowed slightly, just like Dr. Liu thought in his heart, it was really surprising that this hacker had worked so hard to break through the system but did nothing.

"Mr. He, I suggest resetting all the interface passwords first, so that it will be safer", said the panicked man just now, he is the main person in charge of this project Jiang Huairen, if something really happens, his career will be over.

"Dr. Liu, how long will it take to reset all interface passwords?", He Ying asked Dr. with a solemn expression.

"It's about 10 minutes, everyone is here now, maybe it'll be faster"

"Then operate now", He Ying thought about it, this is the strongest server system developed by the trade union, which many peers in the industry have coveted for a long time, and it can't fall into the hands of others no matter what.

Dr. Liu operated the computer in front of him, and after a while, he turned his head, "Mr. He, I still need you to enter the super password", and then handed a data cable to He Ying. He Ying reached out and took the data cable, inserted it into the iCoder in her right hand, entered a string of passwords on it with her fingers, and clicked the confirmation button.

"System password reset has been turned on", an electronic prompt sounded, and the scientific researchers present began to operate their own modules in front of the computer as if they had received instructions, and for a while the crackling keyboard sound in the scientific research room sounded, like the sound of horses' hooves on the ancient battlefield. Just as everyone was immersed in it, a discordant voice interrupted the spectacular scene.

"Doctor, it's not good", a researcher shouted to Dr. Liu, only to see that the screen in front of him went black instantly, followed by the sound of the computer dripping.

"What's going on?", Dr. Liu walked up to him, took over the computer, and typed in various commands, but the screen remained unchanged, only a red exclamation point appeared, and a line of words "No access"

"Everyone, quickly log out of the account, turn off the computer, and ...... Hurry", Dr. Liu shouted at everyone in front of him.

But at this time, it was too late, and then one computer after another lost control, and in just 30 seconds, all the computers in the research room turned into a black screen and red exclamation mark.

At this time, I don't know if it was quiet and terrible in the research room, or the alarm was too noisy, and no one was heard, and everyone drooped their faces, like a piece of wood.

Manager Jiang said angrily: "Dr. Liu, didn't you say that this hacker didn't have a virus?

Generally speaking, when hackers successfully invade, they will install viruses in it to collect or steal information. This kind of is mainly for profit, and you can leave when you get it, so as not to be tracked.

Another is not for profit, using viruses to remove or damage all the files of the target system, causing the target system to be paralyzed, unable to start or even repaired, this kind of hacker in order to seek excitement and prove itself.

But the hacker in front of me is unusual, that is, it does not steal data or destroy files. Based on his previous experience, Dr. Liu didn't know how to explain it for a while, and only cold sweat broke out on his forehead.

Just when everyone looked at each other and didn't know what to do, the screen of one of the computers actually lit up, followed by two, three...... All of a sudden, all the computers in the research room were back to normal.

Everyone was restless and relieved, and Dr. Liu quickly sat down to see that the system was not damaged. But after a while, his face changed dramatically, and he showed a frightened expression.

"Mr. He, all the system files are locked"

He Ying finally understood why the hacker didn't do anything after he came in, because he had been monitoring in the background, just waiting for this super password to grasp the highest authority. Now I feel like I'm so stupid, I don't even think about that. Fingers supported the brow, and his face looked a little helpless and angry,

"Buzz"

Someone sent a communication from the iCoder in his hand, He Ying swiped his finger on it, and when it was connected, a man's voice came.

"He Ying, come to my office"

Hanging up the phone, He Ying thought for a moment, "Doctor, you stay and see if the file can be cracked." Manager Jiang contacted the security company," and then turned around and went to the chairman's office on the 30th floor.

In the chairman's office, He Hongsheng sat on a chair, over fifty years old, somewhat rich, with a Mediterranean-like hairstyle and gray temples. At this time, he was staring at the computer in front of him, and the chairman, who had always been calm, looked a little restless on his face, because the system suddenly couldn't be logged in just now, and there were contracts signed by more than 500 companies, and the amount involved was as high as hundreds of millions, no wonder he was so anxious.
