A confidential approach (preventing hacker intrusion and then obtaining your information)

What are your biggest concerns if your machine is intruded?

In the face of this problem, I think most people will say the following keywords:
Secret leakage caused by theft of tools, source code, and files.

So how can we protect ourselves?
At this time, I beg for anti-virus software and firewall. I am afraid it will be ineffective. Based on the above concerns, I have come up with a solution that is not omnipotent :)

1. Write a program to infect all files in the Local Machine except the system directory or the specified confidential files.
2. The program automatically inserts a specific code function into all source code files.
3. Multiple tags are created at the startup of the current level. If the program finds that the tag does not attack, you can set different features based on different tags, such as-= MO =-mark to determine whether to carry macro code, infect the Office document.

4. The program itself accepts an uninstallation and restoration parameter. When the program is started with the specified parameter, the original program before infection is restored.
5. If no flag is found, there are two main options for program onset and Attack:
1) connect back to the host using a firewall, and provide a simple SHELL for searching, listing, uploading, and downloading files.
2) immediately delete the disk file, overwrite the junk data, and write the BIOS by Directly Reading and Writing the physical memory.
3) if the source code is compiled and run, the attack occurs the same as above.

Protection effect:

1. In this way, you don't have to worry about the secret tools and source code leakage, and give it to people who need it. If beibeibeigo uses exploit.exe, it will be a disaster on their computers.

2. The reconnect function provided by the program will allow you to further trace the other party and reverse the other party.

Friend communication questions:

If I want to send an infected rootkit to someone, I just need to execute this rk with the parameter. The program will automatically restore the original file and send it to someone.

This method can only protect programs and code, but it is not very effective for the documentation. This is also a typical virus. It is not a new era of virus technology :)
