Chapter 517

When Yunfan came to Dingbao, it was already evening.

As there is no direct flight, he changed the plane this time and went directly to Dingbao city.

Fang Yehong personally meets Yunfan at the airport and drives him to the company.

In the car, Fang Yehong is very angry and tells Yunfan the story.

"The scale and strength of this attack are more than ten times stronger than the previous one."

"A lot of computers in the company are paralyzed, some computers even the hard disk is damaged, and even the BIOS information of the motherboard is cleared."

"The spread of the virus is very fast. First, it paralyzes the anti-virus software, and then it spreads quietly. When we find out, all the computers that are on will suffer."

"The whole company is at a loss."

"Even the anti-virus company is still analyzing the virus."

……

"I see."

Yun fan looked at the scenery outside the window indifferently, "by the way, does our company have a top computer?"

"Top match?" The square leaf is red one Leng, "have no."

"Now go and buy one."

"Good."

……

Fang Yehong carries Yunfan to buy a top equipped computer host, and the two return to the company with the host.

Yunfan first checked the company's hacked computer and got a useful information.

This virus is a bit like the "CIH" virus in Yunfan's memory.

The outbreak of CIH virus in 1998 caused a loss of US $20 million to US $80 million.

Of course, it's a computer virus of another earth. It has little to do with the world, and its age is different.

After connecting the host computer to the display screen, Yunfan gets a reminder from Fang Yehong.

"Don't rush to connect to the Internet. I've tried. Once connected to the Internet, the computer will be attacked. The attack seems to be going on all the time."

"Well."

Yunfan first ran the system, and then took out a U disk, "I brought tools, wait a moment, I analyze the virus, should be able to write something to fill the loopholes in the system."

After installing the tool on the computer, Yunfan found a poisoned computer and turned it on.

This time, while analyzing the virus, he racked his brains to retrieve the things in his memory. At the same time, he also inquired about the computer virus history of the world on the Internet.

The whole process is not smooth. Basically, as long as he turns on a computer, the computer will be paralyzed soon.

And the computer that is not poisoned can't turn on the Internet, otherwise it will also be attacked, and their network port has been targeted.

Finally, he and Fang Yehong ran to the Internet bar.

It took Yunfan a whole night to check a lot of information before he found out which loophole the virus had drilled in the system.

Fang Yehong sits beside Yun fan and has fallen asleep.

"Wake up."

Yunfan shakes her and she wakes up soon.

"Well?" Fang Yehong rubbed her eyes and looked at Yunfan.

Yun fan stood up and said, "let's go."

"Good." Fang Yehong stood up in a daze.

……

After the two returned to the company, Yunfan opened a non poisoned computer, tried to write several patches to the system, and then connected to the network cable.

This time, the virus finally disappeared, and the patch played a defensive role.

Fang Ye's eyes lit up, "my God, you actually wrote the system patch yourself!"

"It's nothing. You see, I don't want to find out who's making trouble."

After some operation, Yunfan finally found the attacker's real IP. What made him most happy was that the attacker didn't seem to be in front of the computer. He just made an automatic attack program to attack old wave technology.

What's embarrassing is that the whole company is helpless because of the system vulnerability. Fortunately, the system patch he wrote has played a role, otherwise he doesn't know how to solve the problem.

Following the trend, Yunfan quickly wrote a revised version of "Big Mac" virus, which directly hacked the other party's computer and got a lot of information about the other party's computer.

For fear of being found, he didn't even open the remote, just secretly steal information.

Then, he finally got a useful information, this guy is actually a hacker hired by Ya Mao!

"Ya Mao!"

Yunfan showed a cruel smile.

He quietly removed the hacker's computer "Big Mac" virus, cleared the relevant log, unplugged the network cable, and began to write a new virus.

The leaked version of "Big Mac" was written by him, which combined with "Mydoom" virus, can steal computer files, modify the registry, and disclose those files by e-mail.

After writing the virus, Yunfan connected to the Internet and checked the company and email address of Ya Mao in the world.

Then he registered accounts one by one on the well-known e-mail websites of various countries, wrote some words of cooperation intention between similar companies in the name of cooperative e-mail, and used them as bait to send out the e-mails carrying the new version of the giant MAC virus one by one to various companies all over the world, including the company of Qin state.

After all this, Yunfan turned off the web page and sat in front of the computer, waiting for the hacker to attack again.

He was a little curious. After he patched it, could the hacker hack the computer.

As a technical director, Fang Yehong subconsciously realizes that Yunfan is sending virus.

With doubts, she couldn't help asking, "what did you do?"

Yun fan calmly replied, "it's nothing. It's just a drop in the market value of Ya Mao. By the way, I also told ya Mao's companies all over the country that the culprit is Ya Mao Qin."

Fang Yehong frowned slightly, "if you do this, you will be in great trouble."

"Ya Mao has done this. I'll fight back. I've used countless fake IP addresses, and even the addresses of many hackers have become my protective barrier. Unless you report me, no one in the world knows that I will do this."

Cloud fan turns to see to square leaf red, "so you should know to want confidential?"

"Don't worry, I support you. There will never be a third person who knows about it." Fang Yehong said with a smile, "you really surprised me. Where did you learn these skills?"

"In school." It is impossible for Yun fan to tell her the truth.

If you want him to fight against tianxianzun, you need to write a virus to fight against the enemy. I think he still feels a little sorry.

If only he could not get into this trouble this time, he would go to the Qin Kingdom to destroy their computer room and frighten the enemy.

Even if there are people who want to attack the cloud group, they just need to kill them a few times, and they will be deterred. How can they use such trouble.

"I'm still too kind." Yun fan suddenly shook his head and sighed.

"Well?" Fang Ye looks at him with a puzzled face and thinks he has heard wrong.

The teenager who wrote the virus software himself and wanted to make Yamao's market value fall is actually saying that he is kind?

Is he serious?

Or is it that he can do more than just let ya Mao's market value fall?

After thinking about it, she said, "since you think you are kind, don't be kind. Anyway, I won't tell on you."
