Liu Fangguo's matter has never been told to anyone, it is his biggest secret at present, and he can't imagine how Zhu Zhonghua knew about it. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Zhu Zhonghua sighed: "I really can't imagine that the mysterious madman who subverted the cognition of the entire computer world will actually be you." ”

Liu Fang was puzzled: "Grandpa, where does this start?" I've hacked into other people's computers, but I haven't implanted a fool virus, and I haven't done anything bad, have I? ”

Zhu Zhonghua couldn't help but laugh and said: "Okay, it seems that you don't know what you have done, so let me tell you about it." ”

"A few months ago, the U.S. nuclear strategy department conducted an experiment, and in the course of the experiment, a very serious accident occurred, specifically, they launched a nuclear bomb during the experiment, and if it weren't for the self-destruction device of the nuclear bomb, mankind might have been caught in a nuclear war long ago."

Liu Fang blinked his eyes twice, and said with a puzzled expression: "What does this have to do with me?" I didn't launch that nuclear bomb. ”

Zhu Zhonghua laughed: "It's true that you didn't launch it, but it was launched because of your relationship, don't worry, listen to me explain it to you carefully." ”

"After the accident, the Americans began to investigate, and soon, they found out that a technical department involved in the experiment had been hacked, and after analysis, they finally confirmed that the incident was caused by this hacker, and the hacker's code name is crazy."

Liu Fang's whole head exploded, and he said in disbelief: "This, this is impossible...... It must be that the Americans, in order to shirk their responsibilities, deliberately framed the ...... I—I really didn't do anything bad! ”

Zhu Zhonghua patted Liu Fang's head: "Child, don't be afraid, grandpa will never betray you, no third person can know about this matter, as for whether you have done anything bad, it depends on what you did at the time, if you don't mind, can you tell me what happened?" ”

Liu Fang hurriedly recounted the story in detail, and Zhu Zhonghua frowned after hearing it: "It's really unthinkable that the members of the Wings of Freedom are lurking in such a place!" ”

"Grandpa, can you make it clear? I didn't get it. ”

"The blizzard you fought with is a member of Freedom Wings, and from what you just said, I'm sure he's the one from the technical department involved in that experiment, but you don't know his true identity, but instead you think he's a spy, and in order to sabotage his operation, you secretly modified the program he wrote, and here's the problem, according to what I heard from my old friends after I last returned to the United States, the reason why this experiment failed was because the program was modified."

Liu Fang was a little dumbfounded: "What? Blizzard is、Is it a technician of the U.S. government? This ......"

Zhu Zhonghua couldn't help but laugh and said: "This thing sounds a little ridiculous, mainly because of you, it was you who got the identity of someone wrong, and then made the mistake of almost destroying the world, fortunately, things haven't really developed to that point, otherwise we have to say whether the two of us can meet." ”

Liu Fang trembled involuntarily, his courage was already very small, although he had become bigger after this period of experience, he still couldn't bear such a huge impact.

Zhu Zhonghua saw that his face was pale, so he enlightened him well.

When Liu Fang recovered from his fright, he continued: "The intelligence agencies of the United States are very powerful, and they quickly found out that this matter was done by a hacker codenamed Madman, and after network tracking, they determined the IP address of the Madman in reality, but they did not catch the Madman, so they could only ship all the computers used by the Madman back to the United States for research." ”

"I just said that you have subverted the perception of the entire computer world, and it is related to these computers that have been moved back, and soon after the Americans launched their research, a virus program was triggered, which can completely damage the computer's hardware in addition to using fool-like computing instructions, which is unimaginable in the computer world, according to people's past experience, no matter how powerful the virus is, at most it can only cause harm to the software, and it can damage the hardware of the virus. Sounds like a fantasy! ”

Zhu Zhonghua said this and looked at the computer screen: "If I hadn't seen the fool virus you created with my own eyes, I wouldn't have known that the crazy person in the hacker world was you, which made my evaluation of you instantly increase several levels, at least in the field of viruses, you are currently one of the top people in the world, even if you remove the latter one, it seems that it is not impossible." ”

Liu Fang said bitterly: "What's so good about this kind of reputation? It's just going to bring me a lot of danger......"

Zhu Zhonghua nodded: "That's true, now the intelligence departments of all countries in the world are looking for you, they don't want to arrest you and put you in jail, but want you to serve them, a hacker like you is worthy of an army at a critical moment." ”

Liu Fang laughed at himself: "If they really find me, I guess I will be disappointed, where is my power?" Didn't you beat up a dog by your grandfather? ”

Zhu Zhonghua laughed: "You are very good, you are not proud of doing such an earth-shattering thing, through what you just said, I found that your hacking skills are still very lacking, and the cracking technology you are proud of will definitely be greatly weakened in the future." ”

Liu Fangfei explained: "Why is my cracking technique greatly weakened? ”

Zhu Zhonghua said: "I said before that computer technology has always been developing, especially in software, when a new technology appears, it will soon produce corresponding technology, such as the cracking technology that you currently rely on the most, and someone has developed-for-tat technology. ”

Liu was relieved and asked, "What is this technique?" ”

"The last time I went back to China, an old friend came up with the idea of a firewall, which was mainly aimed at the current situation of weak computer defenses."

"Firewall?"

"According to the other party, the firewall is a tool that can isolate and filter access information, it can be software, it can also be hardware, the main working principle is to screen access data, as long as it is not in line with the security standards of the data, will be turned away, which can greatly limit the spread of the virus, but also greatly reduce the risk of being invaded, especially your cracking technology, is the most targeted."

Liu Fang thought for a while, and then pouted: "I can't deal with the hardware, but in terms of software, it's not me who brags, and it's really difficult for me." ”

Zhu Zhonghua laughed: "If you don't believe it, I'll let you experience it." ”
