Winsock Packet Editor (WPE Pro 0.9a) Pro is a packet sniffing/editing tool which is generally used to hack multiplayer games. WPE Pro allows modification of data at TCP level. Using WPE Pro one can select a running process from the memory and modify the data sent by it before it reaches the destination.
It can record packets from specific processes, then analyze the information. You can setup filters to modify the packets or even send them when you want in different intervals.
WPE Pro could also be a useful tool for testing thick client applications or web applications which use applets to establish socket connections on non http ports.
•Analyze network problems.
•Detect network intrusion attempts.
•Gain information for effecting a network intrusion.
•Monitor network usage.
•Gather and report network statistics.
•Filter suspect content from network traffic.
•Spy on other network users and collect sensitive information such as passwords (depending on any content encryption methods which may be in use)
•Reverse engineer protocols used over the network.
•Debug client/server communications.
•A packet sniffer for a token ring network could detect that the token has been lost or the presence of too many tokens (verifying the protocol).
•A packet sniffer could detect that messages are being sent to a network adapter; if the network adapter did not report receiving the messages then this would localize the failure to the adapter.
•A packet sniffer could detect excessive messages being sent by a port, detecting an error in the implementation.
•A packet sniffer could collect statistics on the amount of traffic (number of messages) from a process detecting the need for more bandwidth or a better method.
•A packet sniffer could be used to extract messages and reassemble into a complete form the traffic from a process, allowing it to be reverse engineered.
