Scholar’s Starry Sea
Chapter 215
In the Dongyuan restaurant, three men and a woman sat at a table in the corner.
At this time, Wu Bin already knew that the senior named Mao Rui in front of him was a programmer in graduate school, and that Qin Senior Sister was here to listen.
After getting to know each other, Mao Rui first looked at Wu Bin opened the mouth and said: "Then I'll just say straight to the point. I read the cheating program you changed. I have very ideas and very difficult to deal with, so I want to ask you to discuss a few issues, don’t you bother?"
Wu Bin waved his hand: "Nothing to bother, Senior is serious."
"You don't need to call me Senior, just call me Mao Rui."
See Wu Bin nodded, Mao Rui went on to say: "You should be familiar with the cracked version in the app market, right?"
"Well, no stranger."
"In fact, these two things have the same principle. These cracked apps are all third-party developers who reverse-translate the original application and add them Or delete and modify some functions, and finally recompile and package them into a new app to release to the application market."
Wu Bin thought for a while, nodded said he understood.
"This problem has always been the biggest problem in the app market. Of course, most people like to play good games for free, but in fact, how can this group of third parties who repackage apps? Good guys, this group of people used to advertise to make some money, but it's getting worse lately."
Mao Rui said, breaking his fingers, "Like a malicious program inserted in it."
, Steal user privacy, tamper with the links inside to deceive traffic or lure users to visit malicious websites, what..."
"But the most important thing is that it affects the interests of genuine apps, right?" Wu Bin Suddenly interrupted.
"hahaha, it seems that my brother is a refreshing person, yes, if it doesn't affect the interests of the genuine, who cares about the user's life and death, then I won't talk to you about blatant justice, let's be practical Yes."
Qin Simeng, who was drinking a drink, was almost choked. This is too much of a vernacular...
And Li Yan is watching them with interest. People, it seems to be very interested in this topic.
After drinking a big sip of iced black tea, Mao Rui patted the table and said: "To control this phenomenon, manual review is of course unreliable. I have to praise Apple here. The ecosystem they have established is It’s really amazing, but Android doesn’t have this life, so there is research on automatic repackaging detection, which is my current direction."
"Outsourcing?" Wu Bin knew that Mao Rui was still there. If you are a graduate student, it is definitely not your job.
"Hey, don’t look down on outsourcing. If you do it well, you will get a large amount of money."
Wu Bin shook his head: "Oh, I didn’t mean to look down on it, just just say it. Ask."
I didn’t mind Wu Bin’s statement too much. Mao Rui went on to say: "My idea is that if the application market can throw all the apks in the market into one tool, then the tool Wouldn’t it be beautiful to automatically recruit those repackaged apps.”
Wu Bin couldn’t help saying after listening: “This has to be solved how to imprint the app, or say “birthmark”. ?, as long as the repackaged files have the same birthmark, they can be distinguished from those applications without birthmarks."
"Professional!" Mao Rui moved towards Wu Bin gave a thumbs up , "This is why I am looking for you. In your modeling, I saw this kind of probability and found that you are definitely a talent!"
"Don't dare to be."
"Whoever you dare to be, don't be humble." After Mao Rui finished speaking, he took out his laptop from the backpack he was carrying, and opened a file to show Wu Bin a directed graph.
"Look at it, the current application uses the interface as the node. When the interface jumps, a directed graph is built for the edge. The label on the edge is the event that triggers this edge. The running process of Zhang Tu can be used as the birthmark of the app."
Then I saw Wu Bin who wanted to ask, Mao Rui said first: "This'birthmark' is not perfect in the current problem. There are still repackaged applications that have escaped various detections. By the way, even many application markets have almost no audit mechanism."
"So the genuine ones are starved to death." Wu Bin Yi Spread your hands.
"Ai, so our generation of programmers has a long way to go." sighed then said, Mao Rui went on to open a file and said: "The code world is one foot high these days. It’s becoming more and more difficult to check the repackaging by scanning the binary code. A lot of garbage control flow, reflection, and magical modification of bytecode, can you feel it?"
"en." Wu Bin nodded.
When the two were chatting hot, Li Yan on the side found that Qin Simeng, who was sitting opposite him, seemed to listen very seriously, but soon discovered that this seriousness did not seem to be aimed at Wu Bin and Mao. The topic that Rui was talking about was aimed at Wu Bin.
'If this is the second dimension, this Qin Xue sister is afraid that love will appear in her eyes. '
"Hey...I'm a pitiful person again."
Li Yan, who has been with Wu Bin for so long, naturally understands how miserable it is for a girl to become interested in Wu Bin Things...
The last whole afternoon was spent in discussions between the two, and Mao Rui's degree of certainty for Wu Bin was getting higher and higher.
"I'm going to have a meal, do you want to bring you a copy?" Li Yan, who listened to it all afternoon, was not as focused as the two in front of him because he couldn't participate in the discussion. .
"Wow, I ordered this." Mao Rui glanced at the phone cry out in surprise, "Then let's eat first."
Wu Bin also nodded, followed Li Yan Let's go for a meal together.
While queuing, Mao Rui asked Wu Bin, "Since you are not from the academy, you are all self-taught?"
"Well, I am very impressed with programming languages. Interest."
This sentence made Li Yan who was behind them couldn't help but sweat. He suddenly remembered that Wu Bin suddenly asked him if he knew about programming languages when he was participating in the competition, that is, he was one year old. I just became interested in programming languages a while ago.
However, how long has it been since? Even the big cows of the University of Science and Technology are sure to treat him.
"Let me tell you, just your brain, if you study systematically, then you will be a market tycoon in minutes, I really don't brag, now the programming world really needs your kind of talent."
"Thank you Senior for your affirmation, but I have no cross-border ideas yet. For now, I still prefer Physics."
"Oh yes, I forgot, you But at the level of "science advances" in the Physics world, cowhide, I have seen so many geniuses at the University of Science and Technology, and I have never seen anyone in your field."
" Yes, I haven't seen it either." Qin Simeng behind also interrupted suddenly.
Mao Rui glanced at Qin Simeng after listening: "You can indeed learn more from him in the future. I promise, if he is at his current level and team up with someone from your college to go to C4, then It’s definitely a handlebar level."
"Um...I heard it." Qin Simeng was nodded, then looked at Wu Bin and said, "If I don’t understand anything in the future, please also Wu Bookworm is not hesitant to enlighten me."
