Best Free Packet Crafting Tools. Packet crafting is the process of manually creating or editing the existing data packets on a network to test network devices. Hackers and network admins use this process to test a network, check firewall rules, find entry points and test network devices behaviors. Network data packets contain various information include data, source address, destination address, version, length, protocol, and few other things depending on the protocol. In packet crafting, one creates a completely new packet or edits the existing packet to change the information packet contains. Then, this packet is sent to the network to see the response of network firewall. By changing values in packet, attackers try to find the entry point in the network to intrude. I also want to point out that packet crafting and packet spoofing are not the same thing. Packet crafting is not a simple task for beginners.
