Windows Forms App for Network Packet Manipulation
Budget: $10 – $30 USD
I need a simple Windows Forms application that captures and manipulates network packets. The application should:
- Detect any incoming network packet on port 12400 of exactly 70 bytes that begins with the following hexadecimal sequence: 46 00 00 00 10 13.
- Upon detecting it, the application should intercept and discard that packet.
- Instead, it should send a new byte sequence.
The new byte sequence is a pre-defined fixed byte sequence that will be sent as a hexadecimal string. The exact string will be provided in a document attached to this project.
Ideal candidates for this project should have:
- Strong experience in C# and Windows Forms.
- Solid understanding of networking principles and packet manipulation.
- Ability to work with hexadecimal strings and fixed byte sequences.
