"It's not just that I have a friend who knows a lot about hacking technology. I want to see if she can do something about it." Yang Ming didn't hide it from Xiao Qing.
"That's fine," Xiao Qing nodded and didn't ask any more questions. After all, the identities of many hackers are hidden from the public, so she changed the topic and continued to ask, "It's better to try than to do nothing. By the way, jewelry fairs." Did it go well? I read the newspaper."
The previous shocking robbery case had been in the newspapers, although Chen Fei had tried his best to downplay the matter at Yang Ming's request. However, there were many parties present that day, which still alarmed the media. However, at Chen Fei's request, Yang Ming's identity was kept secret. After all, if Chen Fei did not provide information, the media would not be able to investigate it no matter how powerful it was. Therefore, the newspapers only briefly reported the bank robbery and the news that all the perpetrators were arrested.
"I read in the newspaper that there was a robbery on the second day after the trade fair opened, right?" Xiao Qing asked. When the report first came out, Xiao Qing was doing experiments, waiting for her to know the news. It was already a few days later, so Sun Jie knew from some side that Yang Ming was okay, so Xiao Qing stopped disturbing Yang Ming. However, now that I have met Yang Ming, I naturally want to.
"Haha, it's nothing. They were just a few gangsters who overestimated their capabilities. They were quickly subdued." Yang Ming said as calmly as possible without getting involved.
"Well, I believe in your ability." Xiao Qing is still very relieved about Yang Ming's adaptability. After all, every time she encounters danger with Yang Ming, Yang Ming can calmly avert danger.
"Haha, what kind of ability are you talking about?" Yang Ming said with a bad smile.
"Disgusting!" Xiao Qing's face turned red and shattered. A rare appearance of a little daughter was revealed.
Yang Ming also knows that this is a laboratory and he cannot do whatever he wants. Some things are just to take advantage of others' words.
"You seem to be very busy recently?" Yang Ming said when he saw that there was no bed in Xiao Qing's laboratory, and the quilt had signs of being frozen. It was obvious that Xiao Qing had slept here.
"Well, I have been studying a new network transmission protocol model recently. I have been working on it with laboratories of several famous universities in the world. I often sleep here in the laboratory." Xiao Qing said.
"Do you have to slow down for a long time?" Yang Ming stepped forward and touched Xiao Qing's crotch, and said, "Staying up late is easy to cause aging. Try to ask your people to do it, and you can just know them."
"Ha" Xiao Qing smiled and said, "You are bad enough to ask others to stay up late."
"It's nothing for those college students to complain." Yang Ming said with a smile: "If you don't pay attention to maintenance, be careful I won't want you."
Xiao Qing naturally knew that the foreign name was a joke. Moreover, Xiao Qing herself paid great attention to maintenance issues. She rolled her eyes at Yang Ming and said, "This doctor is about the same age as me, okay?"
"Haha, just say whatever you want. I'll hold it for a while and I won't bother you. Contact me when you're done." Yang Ming picked up the phone on the table and put it in his pocket, then said.
"By the way, Yang Ming's mobile phone is a confidential device when I am abroad. Be careful when you hold it, so that no one can see it. Don't tell friends who can't trust you." Xiao Qing hesitated and said, "That hacker friend of yours" If my relationship with you is not very good, I’d better not talk about it, so as not to cause unnecessary trouble.”
Xiao Qing is very proficient in technology and knows the consequences of such advanced technology. Since Yang Ming wants to solve the mystery of this mobile phone, then this mobile phone may not have been obtained from normal channels. If it is publicized, it will inevitably attract a lot of attention.
"That friend of mine can still be trusted." Yang Ming smiled after hearing Xiao Qing's words. Yang Ming also knew that Xiao Qing was worried about him. After all, he could never make a big mistake if he was careful.
"Well, I won't talk about the unnecessary bad things. People's hearts are separated from each other, so be careful." Xiao Qing instructed.
"Ha, Sister Xiao Qing, how about I tell the truth?" Yang Ming saw that he was worried about himself and confessed: "The relationship between that friend and me is the same as your relationship with me. He will not betray me."
Xiao Qing was stunned for a moment, and then she understood the hidden meaning in Yang Ming's words. Her face turned red and she said, "Have I seen it before?"
"I must have met Zhou Jiajia in front of the hotel that time." Yang Ming said, "My colleague."
"Well, I'm one of our own. At least I won't betray you." Xiao Qing nodded and didn't ask any more questions.
After leaving Xiaoqing's laboratory, Yang Ming called Zhou Jiajia as soon as he returned to the car. Yes, this kind of decryption problem. Zhou Jiajia should be more professional! Although Xiao Qing is a master in the computer field and even participated in the formulation of some protocols, when it comes to remote technologies, she is not as knowledgeable as Zhou Jiajia. Because after all, Xiao Qing was exposed to some formal technologies and did not want Zhou Jiajia to specialize in these filmmaking technologies.
"Yang Ming?" Zhou Jiajia was obviously very happy when she received Yang Ming's call. She also knew that Yang Ming and Chen Mengyan and Lin Zhiyun were busy with the jewelry exhibition, but Zhou Jiajia felt a little regretful that she could not attend together.
"Jiajia, where are you?" Yang Ming naturally felt Zhou Jiajia's excitement, but she was slightly ashamed.
Sometimes just a phone call can make this girl happy.
"Where am I at school and you? Are you done with the trade fair?" Zhou Jiajia asked
"Well, the trade fair is over. I'm at school too and we don't have time to have dinner together tonight." Yang Ming looked at the time and it was almost dinner time.
"Of course, when? Now?" Zhou Jiajia had already made an appointment with Wang Xue to go to the cafeteria together, but when Yang Ming called, Zhou Jiajia naturally dropped Wang Xue. Wang Xue, who was on the side, pouted in anger after hearing Zhou Jiajia's words.
"It's okay now, I'll wait for you at the school gate." Yang Ming said.
A few minutes later, the salesperson arrived at the school gate. Wang Xue had already gone to find Tian Donghua. Although Zhou Jiajia felt that it was inappropriate to do this, she had not seen Yang Ming for a long time. Zhou Jiajia made a worthy decision to focus on sex over friends.
Zhou Jiajia got into the car with ease and sat in the passenger seat. Chen Mengyan and Lin Zhiyun were not around, so Zhou Jiajia could naturally let go.
"Where to eat?" Yang Ming waited for Zhou Jiajia to get in the car and then started to drive.
"Whatever, you can eat whatever you want. You can also buy something to eat at home. It's quite cold outside." Zhou Jiajia thought for a while and said. "Then let Aunt Li cook something casually. There should be ingredients at home." Yang Ming said, "I will inform Aunt Li right away and ask her to prepare some meals."
Sure enough, Yang Ming called home and confirmed from Aunt Li that there were indeed a lot of ingredients at home, so he could prepare some meals directly.
Yang Ming told Aunt Li to make just two home-cooked dishes, because there were only two of him and Zhou Jiajia, and they couldn't eat too much. Moreover, Chen Mengyan and Lin Zhiyun, because the jewelry fair had just ended, they met with the company to help Zhang Bin and Zhao Sisi with their accounts and handle some large orders at the fair. It is estimated that these two days were Some are busy.
The company also has temporary dormitories where Lin Zhiyun and Chen Mengyan can sleep together.
The school is very close to the Huashang Community where their home is located. Yang Ming and Zhou Jiajia arrived at home just as they started to park. Aunt Li had just started to prepare. Seeing that Yang Ming and Zhou Jiajia came back so quickly, she said with some embarrassment: "Mr. Yang , Miss Zhou, I have just started to prepare. I didn’t know you would be back tonight, and I didn’t get it in advance. I have to wait for a while.”
"It's okay, we're not too hungry. Aunt Li, just take your time, don't worry." Yang Ming waved his hand and smiled.
"That's good." Aunt Li nodded and said, "There are fresh bamboo shoots and cabbage in the safe at home. Can I make bamboo shoot meat and stir-fried cabbage?"
"Okay. Aunt Li, just watch the preparations. Jiajia and I are not picky eaters." Yang Ming said: "Let's go up and study something first. After the meal is ready, just use the intercom to notify us. Call me in the small bedroom. There’s a phone number in there.”
"Okay, Mr. Yang, Miss Shou, go ahead." After saying that, he went into the kitchen.
Zhou Jiajia obviously misunderstood Yang Ming's words. Thinking of Yang Ming kissing and hugging her before, she couldn't help but feel a little disappointed. Before, when Chen Mengyan and Lin Zhiyun were here, Yang Ming would not do anything to her. But now that both of them are gone, leaving only herself and Yang Ming, Zhou Jiajia will inevitably think more.
However, Zhou Jiajia felt a little uneasy. But deep down in my heart, I don’t reject these things. It was just that she was good at reciting poems, so she went up to the second floor with Yang Ming and approached Yang Ming's small bedroom. When she saw Yang Ming on the bed, Zhou Jiajia didn't know what to do.
"Do it?" Yang Ming naturally didn't do that much. Seeing Zhou Jiajia still standing, he felt a little strange, so he pinched his hand: "What are you standing for? This is your own home, so restricted?"
"Oh" Zhou Jiajia blushed. He cautiously sat next to Yang Ming, but there was a little expectation in his heart.
When Yang Ming saw Zhou Jiajia's appearance, he was surprised at first. Then he immediately understood why Zhou Jiajia was like this, and naturally stretched out his hand to hold Zhou Jiajia's soft body in his arms. Zhou Jiajia did not struggle and fell into Yang Ming's arms.
"Kiss Xiao Jiajia, have you looked like your husband these past two days?" Yang Ming saw Zhou Jiajia's shy look. I couldn't help teasing her.
"Ah" Zhou Jiajia felt a little embarrassed when she heard what Yang Ming said: "Why don't we become boyfriend and girlfriend first? We haven't become husbands yet?"
"They're all the same, there's no difference." Yang Ming said boldly, "Don't you want me to be your husband?"
"Of course not." Zhou Jiajia quickly shook her head in denial.
Looking at Zhou Jiajia's cute look, Yang Ming couldn't bear to tease her anymore and lowered his head gently. Zhou Jiajia seemed to have realized something. She trembled slightly and closed her eyes. However, her eyelashes continued to tremble, which was obviously her mood. Very uneasy
Yang Ming kissed Zhou Jiajia gently on the lips. This was not the first time that Zhou Jiajia kissed Yang Ming. Before, he was more bold and proactive, but now he feels a little embarrassed.
Twice at the Alumni Reunion Resort and the Cinema. Zhou Jiajia was silly, a little stunned, and had even forgotten her shyness, but this time it was different. Because Yang Ming was already her boyfriend, Zhou Jiajia was still a little shy.
However, after Zhou Jiajia got used to it, she took the initiative and boldly cooperated.
Although Chen Mengyan and Lin Zhiyun are not at home. But Yang Ming didn't act too hastily. After all, Zhou Jiajia wouldn't refuse if he proposed it. However, Yang Ming felt that it would be better for the two of them to take it step by step, otherwise Zhou Jiajia would definitely feel regretful.
After the long kiss, Yang Ming did not make any other excessive moves. Zhou Jiajia also calmed down and leaned in Yang Ming's arms, enjoying the warmth of the moment.
"Jiajia, do you know anything about decrypting mobile phone passwords?" Yang Ming almost forgot about the main business. He had just asked Zhou Jiajia to go upstairs because of what he was thinking about, but he was a little distracted by Zhou Jiajia's charming appearance and put the phone away. I put the matter aside, lay down for a while and got involved in other things, and forgot my phone again, so I quickly got down to business.
"Mobile phone decryption?" Zhou Jiajia nodded after hearing this, but asked a little strangely, "I know better, is your phone locked?"
"It's not my cell phone, it's someone else's cell phone." Yang Ming took it from the driver Chen Jisheng's hand and said to Zhou Jiajia: "I checked on the Internet, this is dc. "Well, this dc Yang Ming He nodded and said: "Yes, that's the one. Do you have a way to decrypt it?"
"I'm not sure now, but you can give it a try." Zhou Jiajia took the phone in her hand, looked at it briefly, and then said.
"Do you really have a way!?" Yang Ming was a little surprised after hearing Zhou Jiajia's words. Even Xiao Qing called for the death penalty. Zhou Jiajia actually said that he could try it, which means there is still hope for things. However, Yang Ming reminded: "This has no data interface to communicate with the outside world, and it is said that the GE flash memory chip is also unique and cannot be read and written by normal means."
"This is not the main problem," Zhou Jiajia shook her head and said, "There is no data interface. You can find the jtag point that communicates with the CPU on the motherboard of the mobile phone, and use Feixian to complete the reading and writing. Even if there is no chip data, by checking the motherboard u By measuring the connection line between the font chip and the flash memory, the jtag points can also be analyzed from the periphery. However, the key problem is that even if the data is read, the password inside is likely to be in encrypted form, which is equivalent to a waste of effort. , because I don’t know the data of the CPU, I can’t simulate running the mobile phone program on the computer. If I can simulate it, I can use dictionary brute force to crack the password.”
Yang Ming could still understand what Xiao Qing said. After all, it was all orthodox computer knowledge, but the technologies Zhou Jiajia talked about were a bit marginalized, which made Yang Ming very confused. At least he didn't know what jtag was. thing.
"Does that mean the hope of cracking it is slim?" Although Yang Ming didn't quite understand, he could still understand what Zhou Jiajia meant.
"That's not the case," Zhou Jiajia said: "There is another more troublesome way, which is to use the hardware platform of the body and combine it with a computer to complete the crack. It can be achieved from a technical point of view."
"What should I say?" Yang Ming heard that there was still a way, so he quickly asked,
"No matter how it is encrypted or what algorithm it uses, even if it is an algorithm that cannot be reversed at all, when you enter the password, the program will compare it with the correct password. Even after tens of thousands of encryptions During the comparison, there is also a comparison process, and after the comparison, the program performs a judgment and jump. If the password is correct, the boot program will be run. If the password is wrong, the number of errors will be recorded in the information area of the phone. Once When this number is equal to three, the self-destruction program is started. After knowing the operating principle of the mobile phone, it is still possible to crack it." Zhou Jiajia explained: "In this way, there are two cracking solutions."
"Two?" Yang Ming was a little surprised when he heard it. It was already difficult to crack, but Zhou Jiajia actually gave two plans.
"Haha, there are just two plans. Whether they can be successfully implemented is another question." Zhou Jiajia shook her head and said: "I just analyzed it from the commonly used cracking ideas. The first one is relatively simple. But the risks it bears are Very big. Find a way to find jtag's communication store. Read the program, and then crop the password. Then write the previously read program, overwrite the mark recording the wrong password, and restore the program to the initial state. Although this approach It seems simple, but I don’t know if it will cause any adverse reactions, because we don’t understand the structure of the mobile phone, and we don’t know whether the information about the number of password errors is written in the fe chip or written in the CPU or other chips. , if we uninstall other chips, not only will we not be able to achieve the purpose of recovery, but it may directly cause the phone to start the self-destruct program because the error number information in the program is inconsistent with other hardware."
