🦑What is Shell? Understand the concept of Shell in 1 minute! #ForBeginers

> The operating systems we use now (Windows, Mac OS, Android , iOS, etc.) are all with a graphical interface, simple and intuitive, easy to use, for professional users (programmers, network managers, etc.) and ordinary users (housewives, elderly, etc.) ) Are very applicable; the popularity of computers is inseparable from the graphical interface.

> However, in the early days of computers, there was no graphical interface. We could only control the computer through commands one by one. There are hundreds of these commands, not to mention that it is very difficult to remember these commands. "Black screen" itself is a boring thing; computers at this time are far from being cool and popular, and only professionals can use it.

> the only thing that can control the computer hardware (CPU, memory, display, etc.) is the kernel of the operating system. The graphical interface and the command line are just a bridge between the user and the kernel.
If you do not understand the role of the operating system, please go to " What is an operating system ".
Due to security, complexity, cumbersome and other reasons, users cannot directly access the kernel (not necessary), and need to develop another program to allow users to directly use this program; the function of the program is to receive user operations (click on the icon, enter commands) , And perform simple processing, and then pass to the kernel, so that users can indirectly use the operating system kernel. You see, adding a layer of "agent" between the user and the kernel can not only simplify the user's operation, but also ensure the security of the kernel. Why not?

> The user interface and command line are this separately developed program, which is the "agent". Under Linux, this command line program is called Shell .

🦑Streamer scanner tutorial :

"Streamer" software can detect various vulnerabilities such as POP3, FTP, HTTP, SQL, SMTP, and IPC$, and design different cracking schemes for various vulnerabilities, and can easily obtain the detected user password on a vulnerable system. Today I will explore the mystery of "Streamer" software with everyone.

1) First, install the streamer scanner on the computer, and pay attention to the decompression password when decompressing

download : http://prog3.com/sbdm/download/tag/%E6%B5%81%E5%85%89 (chineese hacking)

2) After the installation is complete, we follow its prompts to enter the main program page, where we can see many services in the taskbar. At the beginning, we can see many weak SA passwords by entering the scanned network segment , Or a weak FTP password, or an empty connection for IPC

3) We can see the FTP server used by the other party's machine, so we can provide us with host analysis

4) When scanning, we can add a dictionary to decipher weak passwords,

5) In the options, we will see a lot of services including connection options, system settings, we can perform the services we need

🦑What is a Trojan horse and its 6 characteristics :


1) Does not generate icons.
Although the Trojan will run automatically when your system starts, it will not generate an icon in the "task bar". This is easy to understand, otherwise If you see an icon of unknown origin in the taskbar, you can’t be suspicious!

2) Trojan horse programs are automatically hidden in the task manager and deceive the operating system by means of "system services".

3) Has automatic operation.
The Trojan is in order to control the server. It must follow the startup when the system starts, so it must be embedded in your startup configuration files, such as win.ini, system.ini, winstart.bat, and startup groups.

4) Contains programs with undisclosed functions that may have dangerous consequences.

5) With automatic recovery function.
Nowadays, the function modules in many Trojan horse programs are no longer composed of a single file, but have multiple backups that can be mutually restored. When you delete one of them, thinking that everything is fine and running other programs, who knows it appears quietly again. Like a ghost, it's impossible to guard against.

6) Can automatically open special ports.
The purpose of the Trojan horse program in your computer is not to destroy your system, but to obtain useful information in your system. When you are online, you can communicate with remote clients, so that the Trojan horse program will use the server The communication method of the corpse client informs the hackers so that the hackers can control your machine or carry out further invasion attempts. Do you know how many ports your computer has? Don't you know? Tell you not to be scared: According to the TCP/IP protocol, each computer can have 256 times 256 ports, that is, "doors" from 0 to 65535, but There are only a few that we commonly use. Trojans often use these ports that we don't use much to connect to, opening the door to convenience.

7) The particularity of function.
Common Trojan horse functions are very special. In addition to ordinary file operations, some Trojan horses have the ability to search for passwords in the cache, set passwords, scan the IP address of the target robot, perform keyboard recording, remote registry operations, and lock the mouse, etc. Features. Of course, the remote control software mentioned above will not have these functions. After all, the remote control software is used to control the remote machine for easy operation, not to hack the other party's machine.

🦑Analysis of the OpenSSL program concept and the "heart bleeding" vulnerability that shocked the industry

Public key/private key/signature/verify signature/encryption/decryption/asymmetric encryption

1) Our general encryption is to use a password to encrypt a file, and then decrypt it with the same password. This is easy to understand, this is a symmetric encryption.

2) In some encryption, one password is used for encryption, and another set of passwords is used for decryption. This is called Asymmetric encryption means that the encryption and decryption passwords are not the same.

3) People who are in contact for the first time may not understand it anyway. In fact, this is an application of the principle of mathematics for the product of prime numbers. If you must understand, Baidu has a big You can see a lot of data, and the result is to use one of this set of keys to encrypt data, and you can use the other to unlock it.

4) Yes, yes, both public and private keys can be used to encrypt data. The other is to unlock, the public key encrypts the data, and then the private key decrypts it is called encryption and decryption, the private key encrypts the data, and the public key decryption is generally called signature and verification signature.

5) Because the data encrypted by the public key can only be unlocked by its corresponding private key, you can give the public key to the person and the person, and let him encrypt the data he wants to send to you. This data can only reach you with the private key. , It can be unlocked into useful data. Others get it and understand the content. Similarly, if you sign the data with your private key, then this data can only be unlocked by the paired public key. There is this private key. The key is only you, so if the paired public key unlocks the data, it means that the data was sent by you, on the contrary, it is not. This is called a signature.

🦑FOR ANY REAL WIFI HACKING -TERMUX
HOW TTO Acquiring monitor mode on device?

Running command "airodump-ng mon0" (SSIDs/MACs are censored).
You will need an utility "iw" to be installed which lately will be used to modify Wi-Fi module configuration:

1) pkg upgrade

2) pkg install root-repo

3) pkg install iw

4) Plug in the Wi-Fi USB stick and execute next command:

5) iw phy phy1 interface add mon0 type monitor

6) There shouldn't be any error if kernel is properly configured and drivers support monitor mode.

7) To check whether monitor mode is active, use iw dev.
