So if you want to check a student’s grades 4 and 6, All you need to know is your name and admission ticket number. For students in the same school, It is very easy to get the names of fellow students. QQ groups, Tieba, Moments, and friends around you can easily get a few news sources.

Not just name, Even your ID number, home address, and phone number will all be exposed. In the university, everyone will have their own group, Counselors often send various notices and documents in the group, And there are many detailed information sheets for all students in the department. When I was still in college, I don’t know how many times the counselor uploaded the student information of our department in the group at will. Your ID number, phone number, parent’s name, and home address are all exposed to your classmates.

What’s the use of knowing your ID number in school? Let’s see what a reader said to me.


But regardless of whether everyone in this room is already working, Still a student in school, Want to get a list of the names of any school students, It’s as simple as drinking water. Because there are many schools that will send information about admitted students, Put it on your official website. The picture below shows me searching for a university randomly on the Internet. Found a list of 2019 freshmen in the art category.


I got the name, We can know the grade 4 and 6 of a certain student with only one admission ticket number.

How do we know the admission ticket number of a classmate?

Very simple, This world is made up of countless kinds of rules, Knowing the rules you are God, Overlooking everything. An English test involving millions of freshmen, Their admission ticket number must be composed of certain rules. Then I searched the Internet for what constitutes the admission ticket number of Level 4 and Level 6, You get very critical information.


The admission ticket number for English Band 4 and 6 consists of 15 digits. Know the rules of composition, We have the eyes of God, You can know the admission ticket number of any student.


I found the Excel table of the list of national colleges and universities on the website of the Ministry of Education, All are public information, anyone can download. The last 5 digits of the school identification code in the form are the school code.


Now we can redefine what constitutes a Level 4 and 6 admission ticket number.


As you can see from the picture above, To know the admission ticket number of a student in 2019, The only things we can’t determine at the moment are the school district code, examination room number and seat number. And these three parts are very easy to use code, List all the results, Next is the most important part.

Use the program to simulate the rules of the admission ticket, Request website interface, Get the corresponding data.

The website will send a request to the server when querying the results. Then the corresponding score data will be returned. Through the analog interface, Send a request and we can get the corresponding information. Then I found the interface for requesting grades 4 and 6 through the packet capture software. And verified the accuracy of the information.


The picture above shows me inputting a classmate’s name and admission ticket number. Send the 4th and 6th levels of the requested information, The information retrieved is exactly the same as the picture display.

Know the school name, Have a list of students, Understand the rules for the composition of the admission ticket number, With just a few lines of code, we can hit the grades 4 and 6 of any student.


The way to obtain grades 4 and 6 can be described by a word in hackers: hitting the library.

Bumping the database is a hacker collecting user and password information that has been leaked from the Internet. Generate the corresponding dictionary table, After trying to log in to other websites in batches, Get a list of users who can log in. Many users use the same account password on different websites. Therefore, the hacker can try to log in to the B website by obtaining the user’s account on the A website. This can be understood as a library collision attack.

And I collect all kinds of public information on the Internet, The rules of using the admission ticket number, Send requests through program simulation, Exhaust all results, Crash the library for a student’s grades 4 and 6. As long as you take a moment, Collect the corresponding information, Even if others do not disclose your name and admission ticket number to you, You can find it yourself.

The fourth and sixth results are like everyone’s privacy. Anyone who spends more time can find out all your private data.

Let’s continue to look at a software “WeChat” that everyone uses every day, I did an experiment with my friends, Ask him to send a picture of the scenery around him at will, And use the lack of clarity as a reason, Ask him to send me the original picture. And just such an inadvertent move, he has exposed his home address to me. After getting the photo, I randomly found an Exif information query applet on WeChat, He got his shooting time and detailed address.


You who like to take selfies, show affection, baby, dogs, cats, and all kinds of life photos, Do you feel a deep panic? A photo shared accidentally reveals the address? Why is that?

The key to this is that there is an Exif message in the photo file.

Exif (Exchangeable image file format) exchangeable image file format, Is specifically set for photos from digital cameras, The attribute information and shooting data of digital photos can be recorded. Through Exif, you can see:


These Exif query tools are everywhere, Through itPinpoint to a specific building, And through height information, Combined with the local altitude, evenCan also calculate the floor where the other party lives.

Everyone must remember, If you are not an acquaintance around you, Be sure not to share the original image with others easily. The human heart is the hardest to guess. A picture reveals your home address information, What a terrible thing this is. With your detailed address, Those who have bad intentions do not know how crazy they can do.

There are so many ways to get your privacy in life, And the case of privacy leakage shown to you today, It’s just the tip of the iceberg in the era of naked data. There are many worlds under the iceberg that you don’t know.

But unfortunately, There are a wide variety of extension tools that claim to block ads and protect personal privacy. Let people know how to choose. Here is what Justin Warren, the principal analyst of IT consulting company PivotNine, said: “Install the privacy protection plug-in, Such as Privacy Badger, Ghostery and uBlock Origin, You can block trackers and adware. “All three types of software enjoy a high reputation for privacy protection.

Here I have organized it for everyone, The cancellation method of domestic mainstream websites, Reply to “Privacy” in the background to get it.

3 Use the default login method of the website with caution

It is also a good practice to keep the website or software logged law of attraction revenge out most of the time. You have to carefully consider whether you really need to log on to the website. Because logging in to this website means that you directly tell this website that you are browsing it, Then all the privacy protection techniques in the world will become useless.

Also use trumpets more, At least half of the information leakage can be avoided.
