Liu Cheng looked at the two beautiful women on the screen and sweated coldly on his forehead. Is this going to happen?

Without hesitation, he picked up the phone and called Chen Wanruo. After answering, he immediately asked, "Where are you?"

"I'm looking for some books at Yifu Pavilion. My senior sister has treated me well. She even took me to several campuses, and many campuses are under construction." Chen Wanruo's voice sounded very happy.

Some time ago, wasn’t it called Old Woman Li Man? Now it’s changed back to senior sister?

Chen Wanruo, be careful, Li Man has intentions towards your man, do you know?

"Well, after coming out of the library, prepare for the exam. Although I did a good job in the college entrance examination, I should cherish every opportunity, right?" Liu Cheng's words were very clear, and he asked her to go back early.

How can I give my own cabbage to others?

This woman Li Man, who decided on something, would not give up.

Chen Wanruo looked at the screen of her phone and said with a smile: "Okay, are you working at home again? My sister said that the donkeys in the production team should take a break, and you can go out with Liu Hong to play games and have fun, and stay at home is so boring."

The donkey from the production team?

This guy Liu Yinuo really told Chen Wanruo everything.

"Okay, did you hear that when you go back early?"

"I know, I know, hehe."

Liu Cheng hung up the phone, and he also discovered his own changes. He cared more and more about Chen Wanruo.

He did not refuse this change, whether it was based on possessiveness or machismo, he did not resist this change in his mentality.

Liu Cheng's computer arrived soon. After he assembled the computer, he started to install it. However, during the installation process, he was filled with aftertaste and a little sigh.

The system he installed was called backtrack Linux, which was the most suitable operating system for hackers and white hats at this time. With the development of the times, if he had not written "Best Practice of Enterprise Network Security", he would not have known about this system, let alone used it.

The reason why he wanted to install this system was entirely because this system integrates more than 200 security inspection tools.

The offensive and defensive games he played with Shen Jiayi before were completely a child playing house, and he was holding a wooden sword to chop.

If you want to do a good job, you must first sharpen your tools.

Without good tools or good weapons, he has only enough martial arts and cannot exert any strength on the Internet. It is okay to bully Shen Jiayi, but whatever he wants to do is like a baby walking on the street without clothes.

Liu Cheng looked at the familiar Linux and started his real career.

He first wrote a scanning module and a penetration module. These two gadgets have a common name, and they are called ms17-010.

But it has a more familiar name, Eternal Blue.

If you are still unfamiliar with Eternal Blue, you must have a little impression of the [Red Warning WannaCry Worm-style Ransomware] that swept the world in 2017.

The hijacked computer, all photos, pictures, documents, compressed packages, audio, video, executable programs, etc., will be locked in malicious encryption, and can only be unlocked if you pay Bitcoin to the hacker.

Liu Cheng turned on his laptop, which was installed on his laptop with the Windows 7 beta version that Microsoft is preparing to launch ambitiously.

He took a deep breath, turned on the Eternal Blue Scan module, set up the IP of the laptop, performed the scan, and got the 445 port of the target machine open, and then used the penetration module to set the IP of the target machine, check the relevant settings, and perform penetration.

Liu Cheng got the shell of the target machine, and then began to create the user and password, turned on the remote desktop function, and the link was successful.

Liu Cheng successfully hacked into his laptop through two gadgets he wrote, and connected to the laptop through the remote desktop.

This looks a bit ridiculous, is it that you are terrified?

Is he sick?

It would be easy for Liu Cheng to write another encryption program. It only takes him one afternoon to reproduce the ransomware.

The developer of WannaCry ransomware ransomware has extorted more than $2 billion worldwide.

The developer of GandCrab ransomware, after extorting $150 million, chose to stop.

Because they are financially free.

Only these two small tools are needed, without any operation of the target user. As long as the other party turns on the computer and surfs, he can implant ransomware, remote control of Trojans, virtual currency mining machines and other malicious programs in the computer and server to achieve financial freedom.

A huge mountain of gold is placed in front of him. As long as he is willing, he can use this loophole and blackmail the whole world.

These two remote code execution vulnerabilities based on port 445 and port 139 may not only exist in Windows 7, but almost exist on the current Windows family bucket, including Windows NT/2000/XP/2003/Vista/7/2008/2008R2.

Liu Cheng performed a restart on the remote desktop of his desktop computer and hacked and disconnected.

He stood up, walked out of the house, and shot a cigarette from the Taishan cigarette box, and spit out a mist at the starry sky.

In his previous life, Li Man hated the smell of smoke very much. Every time he smoked, he would go to the courtyard corridor in the corridor to smoke, and he developed such a habit.

After smoking a cigarette, he extinguished the cigarette butts and breathed hard. After a brief thought and hesitation, Liu Cheng turned on the Word of the laptop and began to write quickly.

He did not intend to use this vulnerability to attack computers all over the world. Although he believed that no one would find him, he would be uneasy.

Just like a drug policeman, after he is reborn, he knows countless ways to make money. Will he choose to take risks and gain financial freedom?

Maybe they will use any means to destroy the so-called ways to make money.

Is this the ecological chain degradation of himself as a hunter of the past? He is not happy to do so.

Power has never had the attributes of good and evil, only strength or not.

Just like a sword, it can be used to kill people or save people.

He chose to do a detailed vulnerability analysis and then sent it to Microsoft engineers to receive a small bounty.

Compared with the extortion of $2 billion and $150 million, this bounty is like the difference between a mountain of gold and a gold coin, but Liu Cheng chose the latter.

Vulnerability analysis, overflow analysis, vulnerability functions, program breakpoints, function return values, code error calculation, buffer overflow data analysis, payload function, utilization mechanism, and utilization chain, he completed an extremely complete vulnerability analysis with extremely fast speed.

He looked at the vulnerability analysis he wrote, closed his eyes and thought for a long time before opening the email address and sending it to a Microsoft engineer.

Just like programmers around the world looking for vulnerabilities in Microsoft's new system, he will receive a bounty. Depending on the importance of this bounty, the number can be large or small.

Liu Cheng leaned on the seat slightly depressedly and sent the same content to Shen Jiayi.

"Master! You are too awesome!" After Shen Jiayi received the vulnerability analysis of Eternal Blue, she immediately dialed Liu Cheng's voice.

Liu Cheng said dejectedly: "If you don't know anything, please ask me quickly. I'm annoyed. Do you know what it feels like to fly away from me? Damn, my bullshit conscience is worth a few dollars!"

His heart hurts!

"Master, have you sent this vulnerability analysis to Microsoft?" Shen Jiayi looked at the vulnerability analysis report on the desktop in a horror and secretly swallowed her throat. She knew the value of this vulnerability. If she did something bad, wouldn't it be a mountain of gold?

Boss Liu Cheng said unhappily: "Stop talking nonsense, read it quickly, and ask what you don't understand."

"Master, my apprentice's admiration for you is like a surging river!" Shen Jiayi had a strong admiration for Liu Cheng's skills. Now his heroic spirit of treating money like dirt for Liu Cheng was even more shocked to his bones.

Liu Cheng let out a cold snorted through his nostrils, and the heartache that missed Kingsoft, finally weakened a little. He said impatiently: "Stop flattering, there is no question to ask, I'm dead."

Sure enough, when I was discouraged, only the soft girl could soothe this injured heart.

Shen Jiayi shouted in a howling cry and said, "Master! You know, if you sell it to those gray organizations, you can sell it for at least a few million! Oh my God, my master is such a noble person, so admirable."

"Can you shut up? Can I not know how much it costs? Do you want you to say? Don't sprinkle salt on the wound." Liu Cheng was about to hang up his voice. What's wrong with letting you learn? You are so bored with a rainbow fart.
