 13 | 
 14 | <b>TCP reverse shell</b> is a type of shell in which the attacker creates a connection from the target machine back to the attacker's machine, rather than the attacker connecting directly to the target. In this script, the attacker typically sets up a listener on a specified port on their own machine, and the victim machine is then compromised with malware that establishes a connection to the attacker's listener. Once the connection is established, the attacker has access to a command prompt on the victim machine, and can execute commands and interact with the system as if they were sitting at the machine itself. This technique is commonly used in cyber attacks and penetration testing
 15 | <h2 align="center">Installation</h2>
 16 | 
 17 | <p align="center">Installing and using program process:</p>
 18 | 
 19 | <p align="center">Execute all commands on behalf of the superuser and set your machine ip and port in files</p>
 20 | 
 21 | 1. Download or clone this repository.
 22 | ```
 23 | git clone https://github.com/Untouchable17/Reverse-TCP-Shell
 24 | ```
 25 | 2. Make the file executable with the chmod +x command
 26 | ```
 27 | chmod +x install.sh
 28 | ```
 29 | <br/>
 30 | 3. Run the bash script `install.sh`
 31 | 
 32 | <br>This script will automatically download and install all the necessary dependencies, compile the programs, and then offer you to choose 1 of 3 start options
 33 | 
 34 | 
 35 | > Other Method: Manual Installation
 36 | 1. Downloading or cloning this GitHub repository.
 37 | ```
 38 | git clone https://github.com/Untouchable17/TCP-Reverse-Shell
 39 | ```
 40 | 2. Update system packages and install libpcap
 41 | ```
 42 | apt-get update && apt-get upgrade -y
 43 | apt-get install libpcap-dev -y
 44 | ```
 45 | 3. Compile files
 46 | ```
 47 | g++ ReverseShell.cpp -o ReverseShell.o
 48 | g++ SecureTCPConnection.cpp -o SecureTCPConnection.o
 49 | ```
 50 | 4. Run one of the program
 51 | ```
 52 | ./ReverseShell.o or ./SecureTCPConnection.o
 53 | ```
 54 | <br>You can add the correct path to global like this: `export PATH="$PATH:$(pwd)"` and then you can run the program by just entering their name ReverseShell.o or SecureTCPConnection.o
 55 | 
 56 | 
 57 | > For Windows
 58 | 1. Compile the program using the flag -lws2_32
 59 | ```
 60 | g++ winshell.cpp -o winshell.exe -lws2_32
 61 | ```
 62 | 2. Start the event listener and run the compiled program
 63 | 
 64 | <br>
 65 | <h2 align="center">Install and build the apk file for Android</h2>
 66 | <b>Method 1:</b> To build, use the `gradle build` command in the `Android Studio` terminal. This command will compile the source code and create an `APK file` that can be installed on an Android device
 67 | <br>
 68 | <br>
 69 | 
 70 | <b>Method 2:</b>Install `Android SDK` (Native Development Kit) and compile the program code in C++ with the command `ndk-build` and then assemble the APK file using `ant release` command
 71 | 
 72 | <br>
 73 | <h2 align="center">How to use</h2>
 74 | <p>At first, start listening on the hacker's computer (or on your own) to the port you specified in the file (by default, port 4444), and then run the compiled infected file on the victim's computer</p>
 75 | 
 76 | 1. Starting port listening
 77 | ```

 95 | <h2 align="center">A little explanation of the code and a teaser</h2>
 96 | 
 97 | - This program is a type of software that allows an attacker to gain remote access to a computer or network without the knowledge or permission of the system owner.
 98 | 
 99 | - This code creates a TCP socket that connects to the specified server and port. Then the child process is created using the fork() call. The child process runs the /bin/bash shell, which allows an attacker to execute arbitrary commands on a remote system.
100 | 
101 | - In the parent process, commands are read from a remote client via a socket. The received commands are passed to the child process for execution using the open() call, and the results of executing commands are sent back to the client via the socket. The parent process constantly waits for commands from the client and executes them until the client closes the connection.
102 | 
103 | - In general, this code can be used for illegal access to a computer or network, so its use for illegal purposes is prohibited.

 34 | 
 35 |       "Work" shall mean the work of authorship, whether in Source or

 39 | 
 40 |       "Derivative Works" shall mean any work, whether in Source or Object
 41 |       form, that is based on (or derived from) the Work and for which the
 42 |       editorial revisions, annotations, elaborations, or other modifications
 43 |       represent, as a whole, an original work of authorship. For the purposes
 44 |       of this License, Derivative Works shall not include works that remain
 45 |       separable from, or merely link (or bind by name) to the interfaces of,
 46 |       the Work and Derivative Works thereof.
 47 | 
 48 |       "Contribution" shall mean any work of authorship, including
 49 |       the original version of the Work and any modifications or additions
 50 |       to that Work or Derivative Works thereof, that is intentionally
 51 |       submitted to Licensor for inclusion in the Work by the copyright owner
 52 |       or by an individual or Legal Entity authorized to submit on behalf of
 53 |       the copyright owner. For the purposes of this definition, "submitted"
 54 |       means any form of electronic, verbal, or written communication sent
 55 |       to the Licensor or its representatives, including but not limited to
 56 |       communication on electronic mailing lists, source code control systems,
 57 |       and issue tracking systems that are managed by, or on behalf of, the
 58 |       Licensor for the purpose of discussing and improving the Work, but
 59 |       excluding communication that is conspicuously marked or otherwise
 60 |       designated in writing by the copyright owner as "Not a Contribution."
 61 | 
 62 |       "Contributor" shall mean Licensor and any individual or Legal Entity
 63 |       on behalf of whom a Contribution has been received by Licensor and

 66 |    2. Grant of Copyright License. Subject to the terms and conditions of
 67 |       this License, each Contributor hereby grants to You a perpetual,
 68 |       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
 69 |       copyright license to reproduce, prepare Derivative Works of,
 70 |       publicly display, publicly perform, sublicense, and distribute the
 71 |       Work and such Derivative Works in Source or Object form.
 72 | 
 73 |    3. Grant of Patent License. Subject to the terms and conditions of
 74 |       this License, each Contributor hereby grants to You a perpetual,
 75 |       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
 76 |       (except as stated in this section) patent license to make, have made,
 77 |       use, offer to sell, sell, import, and otherwise transfer the Work,
 78 |       where such license applies only to those patent claims licensable
 79 |       by such Contributor that are necessarily infringed by their
 80 |       Contribution(s) alone or by combination of their Contribution(s)
 81 |       with the Work to which such Contribution(s) was submitted. If You
 82 |       institute patent litigation against any entity (including a
 83 |       cross-claim or counterclaim in a lawsuit) alleging that the Work
 84 |       or a Contribution incorporated within the Work constitutes direct
 85 |       or contributory patent infringement, then any patent licenses
 86 |       granted to You under this License for that Work shall terminate
 87 |       as of the date such litigation is filed.
 88 | 
 89 |    4. Redistribution. You may reproduce and distribute copies of the
 90 |       Work or Derivative Works thereof in any medium, with or without
 91 |       modifications, and in Source or Object form, provided that You
 92 |       meet the following conditions:
 93 | 
 94 |       (a) You must give any other recipients of the Work or
 95 |           Derivative Works a copy of this License; and
 96 | 
 97 |       (b) You must cause any modified files to carry prominent notices
 98 |           stating that You changed the files; and
 99 | 
100 |       (c) You must retain, in the Source form of any Derivative Works
101 |           that You distribute, all copyright, patent, trademark, and
102 |           attribution notices from the Source form of the Work,
103 |           excluding those notices that do not pertain to any part of
104 |           the Derivative Works; and
105 | 
106 |       (d) If the Work includes a "NOTICE" text file as part of its
107 |           distribution, then any Derivative Works that You distribute must
108 |           include a readable copy of the attribution notices contained
109 |           within such NOTICE file, excluding those notices that do not
110 |           pertain to any part of the Derivative Works, in at least one
111 |           of the following places: within a NOTICE text file distributed
112 |           as part of the Derivative Works; within the Source form or
113 |           documentation, if provided along with the Derivative Works; or,
114 |           within a display generated by the Derivative Works, if and
115 |           wherever such third-party notices normally appear. The contents
116 |           of the NOTICE file are for informational purposes only and
117 |           do not modify the License. You may add Your own attribution
118 |           notices within Derivative Works that You distribute, alongside
119 |           or as an addendum to the NOTICE text from the Work, provided
120 |           that such additional attribution notices cannot be construed
121 |           as modifying the License.
122 | 
123 |       You may add Your own copyright statement to Your modifications and
124 |       may provide additional or different license terms and conditions
125 |       for use, reproduction, or distribution of Your modifications, or
126 |       for any such Derivative Works as a whole, provided Your use,
127 |       reproduction, and distribution of the Work otherwise complies with
128 |       the conditions stated in this License.
129 | 
130 |    5. Submission of Contributions. Unless You explicitly state otherwise,
131 |       any Contribution intentionally submitted for inclusion in the Work
132 |       by You to the Licensor shall be under the terms and conditions of
133 |       this License, without any additional terms or conditions.
134 |       Notwithstanding the above, nothing herein shall supersede or modify
135 |       the terms of any separate license agreement you may have executed
136 |       with Licensor regarding such Contributions.
137 | 
138 |    6. Trademarks. This License does not grant permission to use the trade
139 |       names, trademarks, service marks, or product names of the Licensor,
140 |       except as required for reasonable and customary use in describing the
141 |       origin of the Work and reproducing the content of the NOTICE file.
142 | 
143 |    7. Disclaimer of Warranty. Unless required by applicable law or
144 |       agreed to in writing, Licensor provides the Work (and each
145 |       Contributor provides its Contributions) on an "AS IS" BASIS,
146 |       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
147 |       implied, including, without limitation, any warranties or conditions
148 |       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
149 |       PARTICULAR PURPOSE. You are solely responsible for determining the
150 |       appropriateness of using or redistributing the Work and assume any
151 |       risks associated with Your exercise of permissions under this License.
152 | 
153 |    8. Limitation of Liability. In no event and under no legal theory,
154 |       whether in tort (including negligence), contract, or otherwise,
155 |       unless required by applicable law (such as deliberate and grossly
156 |       negligent acts) or agreed to in writing, shall any Contributor be
157 |       liable to You for damages, including any direct, indirect, special,
158 |       incidental, or consequential damages of any character arising as a
159 |       result of this License or out of the use or inability to use the
160 |       Work (including but not limited to damages for loss of goodwill,
161 |       work stoppage, computer failure or malfunction, or any and all
162 |       other commercial damages or losses), even if such Contributor
163 |       has been advised of the possibility of such damages.
164 | 
165 |    9. Accepting Warranty or Additional Liability. While redistributing
166 |       the Work or Derivative Works thereof, You may choose to offer,
167 |       and charge a fee for, acceptance of support, warranty, indemnity,
168 |       or other liability obligations and/or rights consistent with this
169 |       License. However, in accepting such obligations, You may act only
170 |       on Your own behalf and on Your sole responsibility, not on behalf
171 |       of any other Contributor, and only if You agree to indemnify,
172 |       defend, and hold each Contributor harmless for any liability
173 |       incurred by, or claims asserted against, such Contributor by reason
174 |       of your accepting any such warranty or additional liability.
175 | 
176 |    END OF TERMS AND CONDITIONS
177 | 
178 |    APPENDIX: How to apply the Apache License to your work.
