Chapter 199 Lucky and Unlucky

Lin Hong stayed in Kaise's room - after a while, he returned to his room. The other party is reinstalling the system and then recovering the data on the hard disk, which is a very boring process and time-consuming.

It seems that it is difficult for Arthur to have a good rest tonight. When he was poisoned, it was already two o'clock. With such a toss, he can't do it before five or six o'clock.

Lin Hong returned to the room and wanted to study the virus carefully, but there was no way to start. He didn't know much about this area. He poisoned the "MONKEY" virus before, and Arthur helped him recover it.

This April Fool's Day virus has been tricked by the other six members of the SAM Association, and they are all people with a very good technical foundation, which is a great irony.

At the same time, this also illustrates a problem, that is, people's awareness of computer viruses is still very weak, even those who know technology, let alone ordinary users.

Moreover, this time, Lin Hong deeply realized the powerful power of the so-called "social engineering".

When Kevin told him about this before, he didn't think there was anything powerful at all. Psychological weakness? Lin Hong does not think that he has such a weakness. He thinks that he is calm enough and steady enough to do things. It is not easy for others to find their own weaknesses.

But it turns out that everyone's psychological defense is fragile, including him. A simple email can directly handle them all.

Is this the weakness of the soul?

Maybe it's not a weakness of the heart. It's just taking advantage of everyone's trust in your friends. This is a subconscious. For people you are familiar with, you will be defenseless. Because long-term experience tells you that the other party is credible, the email he sent is also credible. This is an extremely simple inertia of thinking Thinking from another perspective, this is indeed the weakness of the soul.

People who are good at taking advantage of this kind of debt, or psychological laws, can often answer their purpose very easily.

Kevin is such a person. He has the same ability as Lin Hong and can sense the other party's emotions in a loss, so he can adjust his strategy in a targeted way, so that he can gain the trust of the other party or let others obey his instructions.

In fact, Lin Hong can't help taking advantage of his talent many times. For example, when negotiating with Josephine White, he can leisurely talk with the other party at the negotiating table, relying on his own ability.

Time passed in Lin Hong's wild thoughts, the window began to shine, and a new day came again.

Lin Hong went out for morning exercise again.

Today, both Arthur and Matthew were absent.

This is completely conceivable. Both of them must have been busy restoring their systems last night.

After going back to the morning exercise, Lin Hong saw Arthur yawning downstairs with dissatisfied eyes, and his whole body was haggard.

"Oh, Arthur, what's wrong with you?" Vina came out of the kitchen with cereal and was very distressed when she saw her son like this.

"Well, I had insomnia last night." Arthur yawned again, then went into the bathroom and began to wash.

"STONE, is Arthur all right?" Vina came to Lin Hong, looked at the bathroom, and asked mysteriously.

"Should it be all right?" Lin Hong was a little strange about Vina's expression, "Maybe it's because I didn't sleep well yesterday."

"Isn't it lovelorn?"

"What..." Lin Hong was stunned for a long time when he heard the words, "Lovelorn?"

"It's with Joanna! He looks like the state when he was disappointed in love. Tell me honestly, is he disappointed in love?

"No." Lin Hong shook his head.

Although he doesn't know exactly what Arthur and Joanna are doing now. However, for today's situation, he is sure that it is definitely not because of lovelorn.

"It's good if it's not a lovelorn, that's good." Vina continued to go back to the kitchen to bring breakfast with a reassuring face.

Lin Hong thinks that Vina's personality is very funny, and he actually hopes to have such a lively mother in his heart. Unfortunately, the chat atmosphere between him and his mother really couldn't become lively. Although he wanted to, he couldn't do it.

When Lin Hong and Arthur came to school, Matthew and Pison had already been waiting in the locker area.

It can be seen that the two of them are not in good spirits, and they are not satisfied with blood in their eyes, which is obviously caused by lack of sleep last night.

"You two didn't come until now." Matthew said listlessly.

"Is it still early?" Lin Hong is a little strange.

"Is it still early? Didn't we agree yesterday that we should come early today to decorate the scene?

"Uh... Is there such a thing? Why don't I know?"

"I forgot to tell you when you came back yesterday." Arthur interrupted, "You weren't there when we discussed it."

Matthew said, " Fortunately, the two of us have pasted the poster, otherwise even the major events of our association will be delayed because of the virus."

"Sorry, I don't know when the virus came in." Pison apologized with some embarrassment. Everyone was poisoned because of his mail.

"How are you doing? Has the hard disk also been formatted? Arthur asked..

"Speaking of this, I'm very angry." Matthew said angrily, "This April Fool's Day virus seems to have formatted the hard disk, but in fact it only modified the partition table of the operating system, creating an illusion that the hard disk has been formatted!"

Arthur's face turned blue when he heard this: "How do you know?"

"Today in the activity room, I went to the forum to read it. There are a lot of people discussing this matter. This April Fool's Day virus is a new music virus. I don't know which bastard made a prank. In fact, it doesn't destroy the data on the hard disk. As long as the partition table is repaired, it

"Correction Four N" Arthur couldn't help swearing, "Yesterday, in order to recover my data, I got it until 5:00 a.m. today!" I wonder why the data recovery is so smooth this time!"

"You're lucky." Matthew said helplessly, "Pison and I have reformatted the hard disk, and all the data is gone."

Pison also showed a sad look at this time. As a technical house, he has saved a lot of good things on the hard disk. He has accumulated these things for several years, but just yesterday, these things were removed by him and could not be recovered at all.

When they arrived at school today, many people joked about the two of them, but they were not in the mood to give a little reaction, and both of them were depressed.

There were still more than ten minutes before the class. The three of them quickly ran to the canteen to have a look and found that it was now full of classmates. Some of them stood there watching the posters posted on the wall by Matthew and Pearson early in the morning, while others raised their calculators and began to receive the cracking program on it to upgrade. Solution.

They looked at it from a distance for a while and then left.

Generally speaking, the effect is still good. Everyone's enthusiasm for this upgrade activity is not bad. Next, it depends on whether the future development can be carried out according to the plan.

Lin Hong's first class was mathematics. Even in class, his classmates sitting next to him privately asked him if he had turned on the infrared transmission function of the calculator. He wanted to crack it. Lin Hong had to take out the calculator and turn on the signal sending function to the outside world, so many boys around him immediately took out their calculators to receive, and then cracked it.

This incident caused a small **, and the result attracted the attention of David, the math teacher.

Lin Hong secretly said that it was bad. Before he could put the calculator away, David had already come this way.

He walked to Lin Hong, took the calculator he had put on the desk in his hand, and then operated it for a while.

"That's great! Has this calculator been modified by your SAM Association?

"Yes." Seeing that he was not angry, Lin Hong also calmed down.

At the beginning, he was really a little worried. After all, this also disrupted the classroom order. If it was in China, the calculator would definitely be confiscated by the teacher. But on the other way, this is the United States, and it seems that such a thing rarely happens.

At this time, in Lin Hong's surprised eyes, David also took out a calculator from his suit pocket, pressed the receive button on Lin Hong's, and began to crack.

Everyone burst into laughter.

Lin Hong didn't expect that David also knew that they were going to release a cracking program today.

After

was cracked, he took out the synchronization program inside and received two small programs from Lin Hong's calculator. He found that the volume was indeed much smaller than before, so he couldn't help nodding with satisfaction.

"NLCEJOBIC is a great job)" David praised.

"Thank you!"

"I want to ask you to help me modify this calculator. I don't know how much I need to pay you?"

Lin Hong originally wanted to tell him to modify it directly for free, but he thought that the association was everyone's after all. Since others need to pay a certain fee for upgrading, the teacher is naturally no exception. The hand said, "30 dollars.

David nodded to show that he could accept it.

Then, he raised the calculator in his hand and said, "STONE, I would like to ask you to tell us about the mathematical problems involved in this compression algorithm, okay? I think other students are also very interested in this. Doesn't everyone think so?"

"David is right!"

"STONE, tell us about it."

"We are really curious about the algorithm inside!"

Everyone echoed it one after another.

Lin Hong hesitated for a moment and finally nodded: "OK."

Therefore, Lin Hong forcibly overcame this kind of exclusion in his heart and walked to the podium step by step. For the first time, he explained the basic principles of the PKZLP compression algorithm to the students like a teacher on the podium.
