Chapter 122

Xiang Kun knows that in the eyes of many people outside the industry, hackers are the most NB programmers.

Generally, the title of "guest" is the king, what kind of hacker red guest white hacker, title with "teacher" is a master, what kind of engineer architect, to the title with "member" is silk

But in fact, there is no difference between top programmers and top hackers. They only specialize in different fields. One is to find ways to meet and realize the needs and build a system; the other is to dig and exploit loopholes to invade the system; one is to study building construction and the other is to study security.

There is no complete boundary between the two. Hackers themselves are subsets of programmers, and programmers can become hackers at any time.

The direction of interest and specialization is just different.

When he was in high school, Xiang Kun was once infatuated with the handsome hackers in movies and TV dramas. He imagined that his computers would be black all over the world, and he would control everything behind the screen. Occasionally, I will follow the tutorial to set up a few bad passwords and poorly maintained websites. However, I haven't done anything in practice. Basically, I just go around and have a peek, leaving a TXT or JPG file to show that I'm here. I'm just a simple script kid.

Now Xiang Kun is familiar with the terms such as SQL injection, cross site scripting, buffer overflow, heap injection, etc., and knows the principle. However, it is impossible for him to attack and invade specific targets. It is not only different thinking habits, but also different understanding and application habits of many loopholes. There is also a lack of other accumulation, such as a lot of spare broilers, reserved back doors, social work databases of different levels, and special tools compiled by oneself or others, which can not be achieved in a moment.

Of course, although the top hackers are powerful, they are not omnipotent.

Just like someone who wants to enter your home, you don't usually smash the door with a hammer, or they disguise as delivery delivery delivery, water meter checking, electricity charging, computer repairing, and delivery delivery Either when you are out of the house or sleeping, you may sneak in through the window, unlock with the master key and sneak in by taking advantage of the imperfect security and the problems of the building structure. Even when you go home after you buy vegetables, you will enter the house with you.

Even if you don't open the door, they can impersonate your identity and help you receive express delivery at your door. They also send express delivery and order delivery in your name.

Unless you blow up all the roads outside your house, it's really a bad thing to be kept in mind all the time.

But the premise of all this is that they know the real address of your home.

On the Internet, the most important information is IP, which represents your location, while the MAC address is your "name". It is just like when someone finds out that you live in a certain hotel, you have to know your name to find out which room you are in and arrest you.

The world is so big that if you don't interact with people and no clues are exposed, specific people may not be able to find you, because they don't know that you are the person they are looking for.

But now Xiang Kun wants to take the initiative to "send parcels" with people who may have malice against him and have the ability to track him. Therefore, we must be careful and be prepared.

The router of that coffee shop is like a doorman who collects express mail at the door of a community. Xiangkun asks him to send a package in the name of Xiaoming. The old man finds the postal brother and gives the package to him. According to the requirements, the postal brother gives the package to Xiangkun's running errand brother a, and the errand brother a gives the package to the errand boy B according to the requirements.

Brother B took the package and gave it to a running brother League. The running brother alliance would pack the package outside and then give it to brother C. little brother C only knew that the package was sent to XX City, so he looked for brother D nearby in XX city to take over the package. Brother D tore up a layer of package and knew that the next destination was XX street. So he found a little brother e nearby XX street to take over, and then he tore it A package, sent to the front desk of XX company.

When the front desk of the company opens the final package, there is no sender's address on it. If they want to return the package to the sender, they can only deliver it to his younger brother E.

Then little brother e looks for little brother D, and little brother d gives it to little brother C. all the way back, they are handed over to little brother B and a, and then they are sent to the security room of the guard. Xiang Kun takes them away in the name of Xiao Ming.

So even if the front desk of the company is controlled by the "villain", and he beats the delivery brother e to death, he can't tell the sender's address, because he doesn't know at all. He only knows that it is brother D who handed it to him.

Of course, this method is not completely safe and can not be traced.

For example, there are "villains" informers in the running errands League, or the "villains" are cruel and pay enough price and manpower to catch little brother D and then catch brother C. Then they will catch up with little brother a and B and torture them one by one.

For example, if Xiang Kun opens the package, the locator will start to work.

For example, to send to Kun a truck of packages, so that he must spend a lot of time to carry, give them time to trace.

But in the end, even if they know from the postal brother that the final destination is a certain community, and even find the gatekeeper, they know that the person who sent the parcel is Xiaoming.But their first reaction must be to search the whole community and find this guy named Xiaoming.

When Xiang Kun, who was spying on the side, found out, he took off his mask, destroyed all the packages, and then retreated.

Xiang Kun has heard that when the police investigate a hacker attack with a bad nature, the deputy director of the Ministry of public security personally supervises the operation. In the middle of the night, the telecom operators switch off to determine the location of the attack. Then the engineer drives the protocol analysis equipment on the vehicle, and one machine room is accessed for inspection. Before dawn, the police uncle is blocked at the door of the suspect's house.

Although judging the other party's high probability has nothing to do with the official, Xiang Kun has always been used to thinking about the imaginary enemy fiercely, when the other party can find his access IP to make a plan.

Just thinking about whether there is anything else I haven't considered, Zhihu replied to a private message from "Kasumi in August".

"Are you a vampire, too? How to prove it? "

Xiang Kun had anticipated the problem and replied, "you can starve more in the daytime than at night. If you don't drink blood when you are hungry at night, it's easy to be manic."

When he thought about answering, he thought about how to prove his identity as a vampire without revealing his identity. The less information he disclosed, the better.

It's as if he didn't say that he was bald, molting, changing teeth, or getting stronger or better eyesight. After all, he wasn't sure whether other "vampires" had the same changes as him. At least the giant owl didn't lose hair and become bald. Once he says that, he will probably let the other party know that he is bald, which is a very obvious feature.

"Kasumi in August" replied:

"are you afraid of garlic?"

"I'm not afraid, but I can't eat. Besides drinking water, I can vomit what I eat. The cross is not afraid, nor is the statue of Buddha. "

"Wow! You're really a vampire! I'm so happy to finally find my kind! "

Xiang Kun looked at the screen indifferently and sneered at her: dress up, then dress.

Then he replied, "yes, I'm so excited! Finally, I've met my kind! "

Kasumi in August: "let's chat with QQ. I'm afraid Zhihu's private message is not safe. Maybe the administrator can see our chat! What's your QQ number? I'll add you

Pipika cachuqiu: "what's your QQ number? I'll add you."

In August, Kasumi: "424423 * * *"

Xiang Kun just wrote down the QQ number in his mind. He didn't even search, let alone open QQ. After a while, he replied, "Oh, I forgot my QQ password, so I can't try it out. Forget it, just say it in Zhihu's private letter. People should not have time to peep into our chat."

Of course, he knows the purpose of the other party using QQ to chat. When chatting private messages on Zhihu, he has less authority. However, when using QQ, it is easy to find a P2P way, and then learn that the other party's IP is equivalent to removing the company's front desk when sending the package, and directly deliver it to the other party's hand. The little brother e who delivers the package will be Just grab it and hit it.

Of course, under the disguise of Xiang Kun, using tor to open QQ to chat with him is not so easy to find out the real IP. But Xiang Kun didn't prepare a new QQ number temporarily, and didn't bother to change the way to toss.

After a while, Kasumi in August replied, "why don't you add a wechat? What's your wechat? Don't tell me you can't remember the wechat password again? "

Pipika cachuqiu: "what are your micro signals?"

Kasumi in August: "Hello! I asked first if it was good

Pipika cachuqiu: "forget it, I think we'd better talk about it first. How did you become a vampire? When did you find out? "

Kasumi in August: "why don't you look like a gentleman? /Poor expression. "

Pipika cachuqiu: "I'm not a gentleman. I'm not sure you're the same kind."

Kasumi in August: "I'm not sure why you sent me a private message? Is my answer clear? "

Pipika cachuqiu: "so how did you become a vampire, and when?"

Kasumi in August: "a lot of things I don't want to say in private messages, either add QQ, or wechat, or call directly."

Pipika cachuqiu: "how many are your wechat and phone number?"

Kasumi in August: "you are too vigilant. You have to get a vest to send private messages? Always ask me for information, but don't tell me about my own situation? If you want to know when I became a vampire and how I became a vampire, you have to tell me your situation first? /Angry expression. "

Pipika cachuqiu: "you speak first, I'll tell you."

After a while, Kasumi in August sighed, and then replied:

"well, I became a vampire a month ago. As for how I changed, I didn't know how. It happened suddenly when I woke up. And you, who was your first food? "Xiang Kun eyebrows a pick, this reply revealed too much information, may be more than the other party did not realize.
