0x00 cause of the event

On Zhihu, there is a great god named Ling Yun telling that he had taken away pornographic websites and educates the site builders. The plot is really exciting and the theme is very positive. It is highly recommended for everyone to read.

The following is the text content.

"I followed the domain name of a pornographic website to find out the real identity of the man behind it, and finally persuaded him to turn off the pornographic website and find a decent job to do a good job."

—— Ling Yun

What I’m going to talk about today happened in September last year. Today I reorganize and write down what happened later.

things are like this

One night I accidentally discovered this pornographic website. I didn't want to bother about it, but I discovered that there were some children's resources in it, and then the following happened.

Initially, I had only one domain name. Experience tells me that most of these websites are registered with fake information. The only real thing is that the domain name is registered in Western Digital.

When I checked the mailbox, I found another website and came to the door for health care. .

I tried to go to a social worker to cheat Western Digital's customer service to obtain more useful information. At that time, I didn't intercept the chat and record it. In order to let everyone feel it more intuitively, I made a special dialog box.

The final result was a failure. The customer service said that there would be technical support for the alleged user privacy and asking me to submit a ticket.

Suddenly remembered that there is a registration function in that pornographic website. At that time, I wanted to try to find the vulnerability of the website, but I didn't expect to register with an invitation code. It was this invitation code from the gave him a fatal blow.

I followed the merchant QQ number I left to check

Using the QQ number as a key word to retrieve the information left on the Internet, I found that he posted a free bracelet bracelet tutorial on a resource network. After downloading this tutorial, I found that there are several pictures in it. I suddenly remembered if the photos were the original Figure probably recorded at the time latitude and longitude taken lead to privacy leaks

After checking the attributes of each photo, there is a GPS location that actually recorded the photo.

Use the latitude and longitude conversion tool to convert degrees, degrees, minutes and seconds, and get the following results

The location corresponding to the latitude and longitude is queried through the API of Baidu Maps, which is in Huixian City, Henan Province.

Based on the above information, the tutorial was uploaded in 17 years, and most of the delivery is to fill in the home address. The other party is likely to take pictures and write the tutorial after receiving the bracelet for free, so I guess that Huixian City is his home. City

In order to obtain more information, I took the risk to contact the webmaster once, and contacted the merchant QQ left on the website because of the need for more invitation codes and whether the price was cheap. He gave me a WeChat payment QR code. This It is of no use to me.

Then I would like to tell him that I work in a gray industry, and I always receive small amounts of money transfers. WeChat and Alipay prohibit me from transferring money. If you want to pay you, you can only add red envelopes to your friends.

My purpose of doing this is to tell him that I am also doing something illegal. First, he can set his WeChat account or Alipay number, and second, he can reduce his vigilance towards me.

After preconceivedly leaving my WeChat account to him, he really got caught.

After he agreed, he immediately turned his circle of friends upright. After I quit his circle of friends, I found that he blocked me. The vigilance has not been eliminated. This has nothing to do. I have found what I want. I am looking through his circle of friends. Saved a photo of his graduation and his WeChat ID

Because I didn’t have the money to buy so many invitation codes, I started to pretend to be a brainless elementary school student to blackmail his invitation codes and scold him directly, saying that you lied to my friend’s money. My friend gave the money but did not have the invitation code. You must He wanted to give me one, and finally got angry and deleted me.

Now that the goal has been achieved, I continue the busy process of digging information, also using his WeChat account as a key word to retrieve the remaining content, and found a post he posted in Huixian Bar

Judging from the content of the post, he is a real estate agency, which also proves my guess above that the other party is indeed from Huixian City.

I went into his post bar and searched through the information and found another post. The current girlfriend or ex-girlfriend is from Haining

And his Tieba account is a number that looks like a QQ account.

Retrieving the information left on the Internet by this Tieba account, I found that he was following Zhengzhou Normal University, and would not follow a certain school's Tieba for no reason. I can't help but guess that he should have studied at Zhengzhou Normal University before.

In addition, I found out that he wanted to buy a clean QQ account. The posting time was in 2015. Maybe he has been doing something illegal since then, and he couldn't confirm it in the end.

Use Alipay to search for mailboxes, search for his QQ size beginning with 110, and find out his real name

I don’t know what his surname is, so I compiled the current survey results, and continued to work with him to obtain more information based on the information I knew.

After buying a new WeChat account, I pretended to be a middle-aged person, set my avatar as a potted flower, and changed my nickname to Follow the Wind. Before adding him to the WeChat account left by Tieba, I went to see the one in Huixian City. The map and 58 city’s house sales information sent him a verification message: "Hello, are there any second-hand houses for sale in Old No. 1 Middle School in the city center?"

He asked me about my budget. I asked him if I could talk on the phone. I didn’t know how to type. At the same time, I inserted a few typos and asked him to leave me a phone number. In order not to arouse his vigilance, I used The number change software changed my number to that of Henan.

The phone was connected quickly. I asked how to call him. He said it would be Xiao Chen. Then he introduced me to a few homes and asked me where I was. This buddy stuttered a little bit funny. Looks like, I don't know how this bird can be an intermediary.

After hanging up the phone, I searched for the mobile phone number starting with 15 that he left for me to add WeChat friends, which is to use his own photo as the avatar (involving privacy and coding)

I verified his Alipay real-name information again, and confirmed that his real name is Chen . After sorting out the current information again, I decided to persuade him to be kind.

He didn't know if I was a policeman or who, so he straightforwardly asked me to open the door and educate him. He told me to close the station tonight, clear the data, and find a decent thing to do.

The pornographic website has been closed since September last year, and has not been able to open it up to now

And what he is doing now, I have no way of knowing, I just hope that he can really reform.

At this point, this incident has drawn a perfect end. The investigation took about a week and finally got a perfect ending.
