"White Knight Certificate?"

Sun Cheng frowned slightly, he didn't know what this thing was. Pen ~ fun ~ pavilion www.biquge.info

"Let me explain!" Lu Qing saw that Lin Rong's face was not very good, so he had to interject and said: "The so-called 'White Knight Special Appointment Certificate' is an honor set up by our Tai Core to report the company's product vulnerabilities and make significant contributions, even if the little brother accepts it, he will not have contractual obligations with our company." On the contrary, every time we update our products, we will send you a free copy of the finished product for trial or testing! ”

After a short pause, he quickly said with certainty: "Since the implementation of the 'White Knight Plan', this is still the first honor we have awarded, I hope you can accept it!" ”

Sun Cheng turned his head, and immediately understood why both of them persuaded him to accept this thing.

Obviously, his skills have been recognized by the other party, and just now he made it clear that he would not consider joining Taicore, so in the case of not being able to recruit him, it is also good to throw out the honor of a 'white knight' to tie him up.

In the future, if a new product is really delivered, he will presumably also help detect vulnerabilities when using it.

After thinking about it for a while, Sun Cheng readily agreed, "Okay, that's no problem!" ”

This kind of free benefit does not have to pay for it, and he is willing to have a few more, not to mention that Sun Cheng also has money to help detect vulnerabilities.

The three loopholes he proposed were all confirmed, although one of them, listening to the meaning of the Tai Core side, they had discovered it not long ago, but this had no effect on Sun Cheng, he was sitting on the side, waiting for the Tai Core to come and talk to him about the reward.

Since Lin Rong was rejected by him again, he stared at a few technicians for vulnerability investigation with a not very good-looking face, especially the problem of the last architectural hardware vulnerability, which quickly made his brows furrow.

In 1989, Intel started with the 386SL processor and introduced the SMM system management model, and it took more than ten years to gradually explore a set of mature models.

The domestic processor manufacturer, Tai Core, was much later than Intel, and it was not until the birth of the Athlon™ series products that this management model began to be applied.

What does SMM say?

It is not an exaggeration to say that it is a convenient model for system designers.

It has a free space independent of the operating system, with a fairly high level of permission, and is usually mainly used for firmware updates or hardware debugging.

In addition, the features designed for system management add the ability to execute all I/O and available system instructions, and any executable unit usually has a buffer, either an instruction cache, a data cache, or both.

Therefore, if the processors of the Athlon series have architectural flaws, resulting in cache vulnerabilities.

Once discovered, hackers will inevitably exploit this vulnerability to directly attack SMM.

If the attack code is running in the SMM space, no security software can do anything against it, because the operating system of a normal PC cannot even read the content in the SMM space, not even the operating system of some enterprise-level servers.

Therefore, compared to the vulnerability that Sun Cheng handed over to Taihe in the morning that the operating system can enter the SMM after five reboots, this vulnerability seems more difficult to exploit but more dangerous.

The former is more likely to affect the security of some personal computers, but the latter can make it easier for hackers to gain access to commercial servers and even supercomputers equipped with Athlon processors.

Which is more important, Sun Cheng believes that the core of the core should be able to figure it out.

Sure enough, Lin Rong thought for a while, then leaned closer and whispered a few words to Lu Qing, the smile on the latter's face quickly disappeared, and his brows furrowed.

After pondering for a moment, Lu Qing asked, "Several vulnerabilities provided by Your Excellency have been confirmed to exist, and I would like to express my gratitude to Your Excellency once again on behalf of Tai Core Company." In view of the danger of several vulnerabilities, I can promise you that the company will pay you a bonus of 80,000 US dollars, but you must sign an agreement with us for a period of six months! ”

80,000 US dollars, this is probably the highest reward set by Tai Core Company for the 'White Knight Project'.

Although Sun Cheng also knew that their external claim of 'no cap' was just a propaganda method, he was still very dissatisfied.

"The bonus is too small, and such a long confidentiality period, please forgive me for not being able to accept it!"

Unceremoniously rejected Lu Qing's offer, Sun Cheng behaved aggressively: "In 2007, the operating system giant Microsoft paid a reward of 170,000 US dollars to Israeli computer engineers Carlotta Buehler and Eforin Berman, just because they discovered a fatal flaw in the Vista system; In 2009, search engine giant Google donated $260,000 to the Kotlerman Lab because the lab discovered and provided it with a malicious linkjacking solution...... The first two vulnerabilities are just that, and the last hardware vulnerability I found may even affect the position of your parent company, Taicang Prefecture, in the field of commercial servers and supercomputers, if exploited by hackers...... You obviously didn't show me sincerity......"

Although he has handed over the vulnerabilities he found to the other party, he only needs to look at the other party's non-disclosure agreement, and now it is not that he should be afraid that he will not be able to negotiate, but that the other party should consider offending a good player with good computer technology, what will be the result?

The most tragic situation is that Sun Cheng was ruthless and anonymously spread the loopholes he found on the Internet.

I believe that when the time comes, hackers and even competitors who are too core will be happy to jump out and make trouble!

Lu Qing looked embarrassed, but after communicating with Lin Rong in a low voice for a while, he still asked again: "Then can Your Excellency mention your request?" I need to talk to the company! ”

"700,000 national dollars, the first payment of eighty percent. The confidentiality period has been cut in half, and I believe that three months is enough time for you to complete the firmware upgrade for all the servers and supercomputers in China. ”

After a pause, Sun Cheng continued: "In addition, I also need a Dawning-IV.c server!" ”

700,000 national dollars, according to the latest exchange rate, is about 105,000 US dollars.

Although he had two other requests, this was still within Lu Qing's acceptable range, so he just pretended to think about it for a while, and he had already agreed in his heart.

didn't want to talk for a while, and then Sun Cheng made another request, which stumped him at this moment.

At present, it is produced and manufactured by Dawning Computer Technology Co., Ltd., the brother company of Taicore, with a total of 19 models of "Dawning-I.", "Dawning-II", "Dawning-III.", "Dawning-IV.", and "Dawning-V.", respectively, for the entry-level of 20,000 yuan, the working group level of 50,000 yuan, and the departmental level of 150,000 yuan. 300,000 yen enterprise level and 800,000 yen high-performance game servers.

Sun Cheng obviously studied it in depth, and as soon as he opened his mouth, he asked for the latest and best performance 'Dawning-IV.c' in the Dawning enterprise-level server, which was priced at 3.78 million yuan on the market.

After a little calculation in his heart, Lu Qing quickly calculated that these requirements were added together, and Tai Hexin would almost have to pay Sun Cheng about 150,000 US dollars.

This is obviously beyond the requirements that Tai Core can accept, and he immediately asked to refuse, "This is impossible, the company can't accept such a high salary?" ”

"Isn't the hardware vulnerability I've found dangerous enough? Or are you too core to believe in your words? I saw that your 'White Knight Project' says that there is no upper limit to the rewards, so I will take the initiative to help you find loopholes! Sun Cheng's tone was also a little scornful.

"This ......" Lu Qing looked embarrassed.

Although everyone in the circle understands that the so-called "no cap" reward is just a propaganda method, there are really people who pretend to be confused and grasp this point, and they really feel that it is tricky.

Just as he was embarrassed, Lu Qing noticed that his cuffs were being tugged, and when he turned his head, he saw Lin Rong giving him a look, and before he could understand what he meant, he actually opened his mouth to agree to Sun Cheng's request.

"The reward of 700,000 national coins can be given to you, the secrecy period can be cut in half, and even the server you want, I can promise you one. Even if the company doesn't agree, I will pay for it myself and guarantee to meet your requirements. ”

Lin Rong said slowly, as if he hadn't seen Lu Qing's changing face next to him, and his eyes were staring at Sun Cheng, "But you have to answer me a question, what means did you use to detect so many vulnerabilities in our processors?" ”

When Lu Qing heard this, he immediately suppressed the dissatisfaction in his heart, and also echoed: "Yes, as long as Your Excellency answers, I will call the company immediately!" ”

That's right, this question is not only Lin Rong's curiosity, everyone here pricked up their ears.

As one of the top processor manufacturers in China, although the scale of the core is far less than that of the international giants, there is no need to question the technology, after all, the old military industry for many years is there, even if there is a gap with Intel in the production process, it will not be opened too much.

Lin Rong is also very confident in the inspection team he brought out, and in the past few years, they have found one vulnerability after another for Taicore.

Although it is impossible for people not to have a time to go, Lin Rong has both the company's technical support and advanced testing equipment, but they are blindsided, and they are stunned that there is no hardware vulnerability that has obviously existed for several years!

It would be strange to say that they would be convinced!

Of course, it's more about curiosity!

"This ......"

Sun Cheng hesitated.

As if seeing that he didn't want to answer, Lu Qing took out his mobile phone and held it in his hand without saying a word, and found a phone number marked 'Mr. Chen' in the address book, but he didn't press the dial button.

After a while, Sun Cheng finally made a compromise and nodded in agreement: "Okay, I can answer this question." I am currently developing an operating system based on linux open source code, and in order to find bugs in the source code, I recently wrote a vulnerability brute force detection software, and inadvertently gave it the ability to detect hardware! ”

What is an invisible pretence!

Presumably that's what he is!

Dida is a high-achieving student, young, and spanning two majors, and is ready to develop an operating system based on Linux open source code by himself.

Shelving, who sees it doesn't think it's cowhide blown into the sky!

But a few of the core technicians in the room have a sore face!

If people want to detect vulnerabilities in the operating system, they have to write their own software, and they also add hardware detection functions, and they accidentally found several hardware vulnerabilities, making it easy to make a small million.

This is simply Chiguoguo's showing off his high skills!

The face is swollen and there is wood!

There was a brief cold scene in the private room for a while, which made Sun Cheng uncomfortable for a while, and he was a fool who was blown up to the sky as a cowhide.

As soon as he was thinking about explaining a thing or two, he saw Lu Qing's mouth open slightly for a while, and finally closed it.

After coming back to his senses, he immediately got up and dialed the phone in his hand without saying a word, and walked out the door while chatting.

With his movements, everyone in the private room came back to their senses one by one.

Seeing that Lin Rong's eyes were glowing and he was about to speak, Sun Cheng hurriedly stopped him from wanting to speak, "I have no plans to sell the software for the time being?" ”

"Tai Core is willing to offer you a satisfactory price to ......," Lin Rong still did not give up.

Sun Cheng just shook his head, he really didn't have the idea of selling the 'Sky Eye'.

First, this is the first software written by myself using my ability, and I am somewhat reluctant.

Second, I can still use it if I am writing an operating system, not to mention that the construction framework of Tianyan is good, and there is potential for further enhancement in the future.

"Little brother, you really have to think about it carefully, a software development is easy, the most difficult thing is to improve, it is not something that can be done by one person. What's more, its role in your hands is limited after all, it is better to sell us too core, but the improvement of domestic CPU is greater! ”

Under Lin Rong's stubborn fighting, Sun Cheng finally didn't say anything to death, and after thinking about it for a while, he promised: "I still need it for the time being, and I don't plan to sell it." But if you have this idea in the future, you must be the first to contact you! ”

Lin Rong wanted to persuade him again, but seeing that he was resolute, he had obviously made up his mind.

After thinking about it, I felt that the development of the 'operating system' was as difficult as the sky, Sun Cheng was too young to understand how deep the water was in this field, and he would definitely suffer losses in the future.

When the time comes, not only may the vulnerability detection software developed be sold, but even after he himself has been smoothed out, the core of Tai Core may not be able to be used for his own use.

Thinking like this, the obsession in my heart couldn't help but fade a little.

The phone call didn't last long, and Lu Qing quickly returned to the private room, and the smile on his face regained.

His eyes met Sun Cheng's eyes, he nodded slightly and made an OK gesture, "The company has agreed to your request, and the bonus will be credited to your account later, but the server will be delayed, and it will be delivered in about three days!" ”

Sun Cheng suddenly showed a smile, he knew that his dream was about to set sail!
