Liu Lingyun turned on the TV as usual to watch the morning news, drinking milk and eating bread. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

"The following is a piece of news from the United States, a young man named Bill Gaishi developed a computer system called Windows that has now become popular in the United States, let's take a look at the interview with it."

Liu Lingyun almost didn't squirt out the innermost milk when he saw the news, Windows system!

At this time, I saw an American boy with a beautiful face coming out of the TV, who looked like he was only in his 20s, and it seemed that it was the first time he was interviewed by reporters, and he was a little shy.

"Hello Mr. Bill Guys, you look so young, why would you want to develop such a software?"

"I'm a computer enthusiast myself, and I want to make computer users use a safer and faster computer interface, and this software has been completed with the help of many people."

"What do you think about the development of the new computer industry?"

"I think the computer will be a great invention that will change the world, especially some of the predecessors in computer science have made me deeply aware of this."

"At present, this system has reached 60% of the usage rate in the United States, and there is an upward trend, and there are also loyal fans of the Windows system abroad."

…………

This news was really like a bolt from the blue, and Liu Lingyun was completely stunned. She ran back to the bedroom and turned on her personal computer.

That's right, I noticed it before! Windows system itself has five pen Larry and other input methods! There is also a mode of pure English input, specially designed for foreigners!

Who the hell is L! Is he a foreigner? Thinking of this, Liu Lingyun immediately logged in to his forum number and shouted L.

"God L is not here!"

"Great God? Is it there? ”

"God, have you read today's news?"

"Great God, are you Bill Gaishi?"

"Great God!"

…………

Finally, after several hours of bombardment, she finally waited for L.

Luffy Yu was also stunned by her version after version of the news.

"Bill Gaishi is just a friend of mine, and you use the China version, but Bill Gaishi has promised me that all future input methods will be made by me."

Luffy didn't dare to tell her that this Windows had been modified by herself, and if she did, she didn't know what the problems would be with this little girl.

"The great god of L is worshiped by the little woman! My admiration for you is like a surging river, and the little girl has a small request at this time! ”

Luffy Yu also has a headache for this little mushroom, although the other party is a cute girl, but it's too difficult!

"Okami, do you know about hackers?"

"I don't know!"

"L God!"

She didn't believe that L, a computer expert who didn't understand a little bit of computer technology, would kill her.

"Okay, what do you think you want to learn?"

"Great God, I want to learn the technology of computer invading!"

Luffy Yu is also communicating with Little Mushroom every day these days, and he also deeply knows that this guy's computer level is also very high, even better than some boys.

"Well, today I'm going to teach you a unique trick that no one in the hacking world knows yet! Social engineering! ”

"Social engineering?" Liu Lingyun also came to the spirit when she heard it, and she also knew a lot of hacking techniques, such as Trojan horse attacks, and attacks on some ports. But this was the first time she had heard of social engineering.

"The so-called social engineering is a method of deception through psychological traps such as psychological weaknesses, instinctive reactions, curiosity, trust, greed, etc., to achieve self-interest."

"Sounds so hard." Liu Lingyun couldn't help but shake his head.

Even on the other side of the computer, Lu Feiyu seemed to see the cute expression of the little mushroom and smiled: "Generally speaking, social engineering is an art and science that makes people obey your wishes and satisfy your desires. ”

Social engineering is also a new discipline for the present world, not to mention that some hackers are still in the stage of ignorance, let alone systematic knowledge. Luffy Yu sorted out his thoughts and said again.

"All social engineering attacks are based on cognitive biases that make people decide, sometimes referred to as "human hardware vulnerabilities." ”

"I still don't understand! It's harder than writing code! ”

Luffy Yu is not in a hurry, it is indeed a bit difficult for people to talk about this now, and he thought about it again.

"If you go to a restaurant and you don't have any money in your wallet, you put a bug in the meal, and you can ask the restaurant for free food."

"But before that, you also have to do a good job of disguise, for example, you wear decent clothes and drive a luxury car, so that you will not be suspected by the hotel, if the disguise is successful, you can not only be exempted, but also ask to go to the back kitchen to see more information!"

"Ahh I understand that it's an empty glove white wolf! ”

"It can also be understood that social engineering is a very important technique in hacking techniques, and you have to remember to use it to get anything you want, passwords, top-secret information, entry parameters."

At this time, Luffy Yu smiled and said, "For example, your name is Liu Lingyun, and your birthday is June 26." ”

Liu Lingyun was really taken aback, he had never told the other party his name!

"How do you know my name is Liu Lingyun!"

"This is the best example of social engineering, I implanted a Trojan horse in the photo I sent you before, and obtained the secret liulingyun0626 of your computer boot, and I only knew the pronunciation before you said the words Liu Lingyun, and June 26 also relied on guessing, this is the best list of relying on false information to get the desired content."

"Oh my God, this is terrifying!"

"Not only that, but now I only need to open Wandu and provide my name and birthday to retrieve your forum login password, and you must know that the number of passwords that ordinary people have is 1 to 3 and people under the age of 18 have 1 to 2 passwords, that is, I now have all your passwords."

Liu Lingyun couldn't help but break out in a cold sweat, this guy is too perverted, but no matter where he is, he only has a password of name and birthday, isn't this just a plan?

Luffy Yu is now confident that through such a chain reaction, he can know the height, blood shape, and measurements entered by the other party on the website. Take a step further and look at your browsing history, and you can even know the other person's interests and hobbies.

Know how important this is for a girl.

Liu Lingyun said: "What is your name, what is your birthday, tell me quickly!" ”

This Nizi still wants to trick me, thinking of this, Luffy Yu hastily ended today's teaching.
