Packet Sender is a must have in every security researchers tool kit. It allows easily recording and sending UDP and TCP packets. It is a great help when analyzing malware communication and reversing their protocols.- Peter Kleissner, CEO of Kleissner & Associates

- In the bottom right, there are UDP server and TCP server status and port. You can click to activate or deactivate these.
- During packet resending, there will be a button to cancel all resends.
- Please check your firewall. Windows aggressively blocks TCP-based servers. Packet Sender will still work if the firewall blocks it, but it can't receive unsolicited TCP-based packets.
- In the table, there is a list of saved packets. You can double-click to directly edit fields in this table.
- Fields can be rearranged by drag-and-drop in the settings tab.
- A resend value of "0" means it is a single-shot packet.
- A packet has a name, destination address (domains will trigger an IP lookup), port, and data associated with it.
- Click "Test" to immediately send. Click "Save" to send later.
- Packet Sender supports mixed ASCII and HEX notation:
- \XX gets translated to XX in hex
- \n and \r will get translated to 0A and 0D
- HEX numbers are space delimited
- Example ASCII:
68 65 6c 6c 6f 20 77 6f 72 6c 64 0d
- You may save a packet directly from the traffic log. You will be prompted for a name, and the source address and port will be switched for your convenience.
- An optional response can be sent. The same response is used for TCP and UDP.
