Native client-server architecture for remote system administration.
This is a native Delphi 12 implementation of a TCP-based remote administration system that can gather system information, manage processes, and execute commands on a target machine.
This project is only intended to be a base for beginners to build on top of. It is not production ready, not feature rich, not secure.

The tool establishes a persistent connection between a client process and a server interface.
If a client connects to the server:
- Client attempts connection to server IP/Port
- Client sends system info (JSON)
- Server displays client in ListView
- Server processes commands
- Client executes commands remotely
- Updates UI with results
This allows remote monitoring and control of a Windows machine via TCP sockets.
- Native Win32 / Win64 Delphi implementation
- Uses TIdTCPClient and TIdTCPServer (Indy components)
- Multi-threaded command processing
- JSON data exchange format
- Single instance enforcement (Mutex)
- System hardware info extraction (HWID, CPU, RAM, Disk)
- Process management (Kill, List)
- UAC Bypass capability (FodHelper)
- Delphi 12 (or compatible version with VCL)
- Windows OS

Client Console Executing Commands:
[2026-01-01 12:00:00] [INFO] Attempting connection to 127.0.0.1:9000...
[2026-01-01 12:00:00] [SUCCESS] Connected to 127.0.0.1:9000
[2026-01-01 12:00:00] [SUCCESS] System info sent.
[2026-01-01 12:00:01] [INFO] Executing FodHelper UAC Bypass...
Client Console Successful Connection:
[2026-01-01 12:00:00] [INFO] Connected to 127.0.0.1:9000
[2026-01-01 12:00:00] [SUCCESS] System info written to system_info.json
The communication protocol is plaintext based:
| Prefix | Meaning |
|---|---|
| INFO | [SysInfoJsonData] |
| OUT | [ExfilResponseData] |
| CommandName | Execute function of same name |
The algorithm handles connection attempts:
Connected → Send INFO|JSON
Loop → Wait for command
Execute → Send OUT|Result
When a command is received, the client:
- Maps command string to procedure
- Executes locally on remote client machine
- Sends result back via socket

- Network programming study
- TCP protocol implementation
- System interop (Registry, Processes)
- Lab environments
This tool is intended for educational purposes and controlled environments only.
- Requires network connectivity
- Dependent on VCL/Indy components
- Not optimized for high-latency networks
