Late at night, in the office of the English Teaching and Research Group of Chenguang Foreign Languages College.
Click! Suddenly, there was a clear sound of unlocking in the silent night.
Immediately, the office door was pushed open.
A man wearing a hood, with only two eyes exposed, walked in furtively, and then closed the door behind his back.
He came to Yu Haibo's desk quietly and skillfully, sat down, and opened the computer with his hands wearing thin plastic gloves.
Soon, the computer displayed a desktop with blue sky and white clouds.
Bang bang bang bang... The man operated quickly on the keyboard, pressing the mouse from time to time.
After a while, he stopped operating.
A folder appears on the desktop.
Open the folder, inside is a code editor and a txt applet with a changed suffix name.
Opening the code editor and the applet respectively, the man's eyes suddenly showed a look of ecstasy.
In the code editor, there is the entire source code of the spider virus killing software.
txt applet contains all the codes of the spider virus.
Chen Hao originally wrote these two softwares on Yu Haibo's computer, passed them on to others, and then deleted them.
Although it is permanently deleted, as long as you know some computer skills, you can use software to restore it.
The man immediately plugged in the USB flash drive and copied the code editor and txt applet to the USB flash drive. After confirming that there were no errors, he unplugged the USB flash drive.
Then, he restored Yu Haibo's computer to its original state, shut it down and turned off the power.
Later, the man came to Chen Hao's desk, turned on the computer, and started the same operation.
After a while, the source code for generating the serial number of the spider virus killing software appeared on Chen Hao's computer.
"marvelous!"
When the man saw this, he couldn't help but whispered excitedly, and quickly copied the serial number generation code with a USB flash drive.
He unplugged the USB flash drive, restored Chen Hao's computer to its original state, then turned off the power. After looking at it carefully several times, he confirmed that there were no mistakes and quickly left the office of the English Teaching and Research Group.
At night, tranquility returned.
The time comes for the next day.
The teachers in the English teaching and research group went to work and didn't notice anything strange at all.
Yu Haibo turned on his computer to work and found no one had touched his computer.
In the afternoon, after Chen Hao finished the regular meeting of the secret department and the Cultivation Alliance, he went to Chenguang Foreign Languages College to do some eating as usual.
After greeting fellow graduate students, his supervisor Professor Su Zhenguo, and old colleagues, Chen Hao was about to return to Haoyuan.
Suddenly, the mobile phone rang.
When Chen Hao saw that it was an unfamiliar landline, he picked up the phone: "Hello?"
"Is this Teacher Chen Hao?"
A male voice came from the phone, his attitude was very polite.
Chen Haodao: "I am, where are you?"
The male voice said: "I am from the inspection department of the headquarters. My surname is Kang and my name is Kang Mingyang."
Chen Hao said: "Do you have any problem with me?"
Kang Mingyang said: "There is one thing, Teacher Chen, aren't you the developer of spider virus killing software?"
Chen Hao said: "Yes, what's wrong?"
Kang Mingyang said: "Today, several people claiming to be from Huanyu Software Development Company came to the school and said that the spider virus killing software you developed was theft of the anti-virus software developed by their company. It has caused huge losses to their company and asked the school to deal with it.
, and demand compensation.”
Chen Hao was speechless: "Is it because of touching porcelain?"
Several days have passed since the apology ceremony of the School of Computer Science. After installing spider virus killing software at the Nanjiang University headquarters, all network offices have returned to normal.
After hearing about the spider virus, other universities, research institutes and other institutions asked for help.
Although Chen Hao was willing to help, because more and more people were asking for serial numbers, he was so annoyed that he handed the software over to the school for processing.
Anyway, he doesn’t point to killing software to make money.
I didn't expect that there would be people here.
Kang Mingyang said: "We thought so at first, but the other party took out the source code of the spider virus killing software, and after testing by the School of Computer Science, it was confirmed to be true."
Chen Hao was surprised: "They have the source code?"
Kang Mingyang said: "Yes, Teacher Chen.
Now the other party is strongly demanding that you take responsibility for this, can you come to the headquarters?"
Chen Hao said: "Okay, I'll go over right away. I'll be there in twenty minutes."
Kang Mingyang said: "Okay, we'll wait for you."
Chen Hao hung up the phone, thought for a while, and turned back to the teaching building.
The source code of the spider virus killing software was only available on Yu Haibo's office computer. He deleted it after he finished compiling it.
Now, what others get is preformed software. At best, they can only see the running code through the background, and it is impossible to see the source code.
If the source code provided by the person from Huanyu Software Development Company is true, then it can only be stolen through Yu Haibo's computer.
"What's wrong? What did you leave behind?"
Yu Haibo and other teachers saw him leaving and coming back, and asked in surprise.
Chen Haodao: "I remembered something, Teacher Yu, if it's convenient for you, I can use your computer to check something."
"It's convenient, just use it."
Yu Haibo stood up and gave up his seat.
Chen Hao sat down and used technical means to check the computer usage traces.
The result is normal. There are only various traces left by Yu Haibo in the computer.
Chen Hao thought for a while, opened a notepad, wrote a few lines of code, saved and exited, changed the suffix name of the notepad, and then pressed Enter.
The new applet is running.
After a while, rows of records appeared in the program format box.
Chen Hao looked at it and suddenly his eyes narrowed.
Around 1:30 this morning, Yu Haibo's computer actually had startup and usage records.
This could never be used by Yu Haibo.
And the next record is to use technical means to erase traces of computer usage during this period.
Chen Hao sneered.
No wonder he couldn't find any other traces of use except Yu Haibo using conventional means.
It seems that the person who sneaked into the office of the English Teaching and Research Group late at night is a technical expert.
However, this method is enough to hide it from ordinary people, but for Chen Hao, it is transparent.
Chen Hao closed the mini program, performed some operations, and easily restored the erased usage traces.
Sure enough, the source code of the spider virus and the source code of the killing software he compiled were recovered and copied away using a USB flash drive.
Chen Hao can even see the specific time when the USB flash drive is inserted and removed, accurate to the second.
"You want to frame me with just this little trick?"
Chen Hao sneered in his heart, took out a USB flash drive, copied down the traces of theft recorded by the mini program, and then made a file shredder to completely remove the source code of spider viruses and anti-virus software.
In this way, unless someone has a higher technical ability than him, it will be impossible to obtain the source code of spider viruses and anti-virus software from Haibo's computer.
"Teacher Yu, I've finished it, thank you."
Chen Hao pulled out the USB flash drive, stood up and said.
Yu Haibo smiled and said: "Why are you so polite?"
Chen Hao sat down at his desk again and turned on his computer.
Although the thief stole the source code of the anti-virus software and spider virus, the source code without the serial number is still useless, so he will definitely open his computer and continue to steal.
