Chapter 541

If it weren't for the fact that he had encountered this kind of thing, if he hadn't known the industry insider Northwest Wind, Chen Bo would have been afraid that it would be difficult for him to know that there was such a profession in a short period of time.

With Northwest Wind's explanation, Chen Bo knew what this thing called the social worker library was.

Hackers usually hack into an online site that they find valuable, and then steal all the user data and information on that site.

However, because there is so much user information stored in the website, it is necessary to collect this information and store it in a centralized manner so that it can be found later.

And this place used by hackers to store information is the social worker library.

After the hacker collected a large amount of user information, it was stored in the social worker database for sorting and classification, and it was divided into different types according to different uses.

Hackers only need to log in to the website of the social work database set up in advance, and they can enter the social work database to query the information they want, of course, it is not only hackers who can do this, as long as this website has always existed, then even ordinary people can also query other more private information by entering other people's common information (such as mobile phone number, QQ number).

For example, the family situation and social experience exposed by Chen Bo and Chen Xiaoyan after being doxed are actually queried through the social worker database.

"Have you ever done something like that?" Chen Bo asked.

"I'm all for legitimate purposes, to eliminate evil and promote good, and I'm also buying information, so I can't say it......"

Chen Bo was speechless, but in the face of such a situation, he was helpless.

I can only listen to the northwest wind and continue.

"There are several industry terms in this, the first is dragging, which means hackers hacking valuable websites and stealing databases, and the other is library washing, which means cleaning data and monetizing valuable data for transactions, and the third is credential stuffing, which is to get the data to log in to other websites or APPs, and the last one is the social worker library, which is very complicated......"

According to the Northwest Wind, the sources of this data are also complex, one is that hackers program the data to steal it, and the second is that it is difficult to prevent home thieves.

One is that hackers will drop Trojan viruses in many websites, and obtain the information filled in by the registered users of these websites through crawlers, including home address, age, gender, contact information, etc., once successful, they will be placed in the social worker database by hackers, waiting for people in need to buy them.

The second source of data is more hateful, the internal staff of the major websites. As the saying goes, "Day and night, it's hard to prevent thieves." "So a lot of websites are defenseless against their internal employees.

These employees who work inside the website will naturally have easy access to user information, and a considerable number of employees will sell the private information of the users of these websites to the illegal personnel who control the social work database in order to obtain illegal benefits.

After all, hackers still have to write a variety of code to get into the website to obtain information, and the probability of being found is not small, but these employees will not arouse the company's suspicion, so a considerable part of the user privacy information stored in the social worker database is sold by the insiders of the major websites themselves.

The user information stolen by employees and hackers can cover many different things, depending on what software or website the user has registered with.

So why would hackers build such a pool of social workers? The reason is simple, there is a demand and there is money.

After all, where there is demand, there will be a supply chain, and if someone wants to obtain other people's information through illegal means, someone will definitely satisfy their idea.

Hackers are what they want, but hackers aren't philanthropists either.

So if someone wants to get information about others from the social worker pool, they have to pay these social worker organizations. And this is one of the sources of income for the establishment of a social worker pool organization.

Another source of income is the data of ordinary users, which is sold in large quantities by the social worker pool. The premise of the kind of income mentioned above is that the information of the person being queried is very valuable, so people are willing to spend money to check the privacy information in the social work database.

What about the other information of ordinary people collected by the social work database? After all, there are still a few people who are willing to spend money to check other people's information on the Internet these days. Still, the social worker pool found a buyer for the information of these ordinary users, who are notorious online fraud companies.

I believe you have been very puzzled, obviously you don't seem to have posted your phone number and personal information on the Internet or published it, but you can always receive all kinds of Internet fraud calls, and you can also tell your personal information about the Tao, as if you know you better than your parents.

In fact, they may really know you, of course, in addition to scam companies, many financial companies and real estate companies are also among the buyers of the social work pool. However, they do not buy a large amount of user information to make scam calls, but to collect this data to accurately locate users.

When the information of ordinary users is in the social worker database, it has been classified according to the information obtained, such as different groups of people according to family status, marital status and financial management.

Once a financial company or real estate company obtains this large amount of data, then they will accurately recommend the required services to users based on these classifications. For example, knowing the user's family situation, the insurance company in the financial industry can accurately recommend the insurance that the user needs, such as personal accident insurance, critical illness insurance, and even car insurance.

The same is true for the real estate industry, if you know the user's marital status and financial situation, you can judge whether the other party needs to buy a house, decorate, etc., so as to accurately recommend the user's needs.

"Do you know someone who has a social worker pool?" Chen Bo's last sentence startled the northwest wind.

"It can't be said that it's an acquaintance, it's just a need for work, so it's normal to have a connection, right?"

"Help me find someone like this, I want to meet the person you are trading with, nothing else, I just want to learn a little bit of their crawler skills, programming or something......" Chen Bo said.

The northwest wind was stunned for a while, and it took a long time to say: "Who believes what you say, you don't want me to deceive people and then ......"

"I'm not a policeman, you don't have to worry about this, besides, is it useful to catch this one, I really want to learn something, put meat on the net shark as soon as possible, I'll make a call and let my parents go out and hide for ......a few days," Chen Bo finished speaking and left.
