WPE PRO was one powerful tool being used by a lot of players. Just like any packet editors, this was often used to for spamming which, in turn, termed as “speed hack” by many players. However, the timeouts in the server has been fixed long time ago so it doesn’t work nowadays.

This software are used to be interpreted as a Trojan or some type of virus by many antivirus softwares that, at many times, this was often deleted right after download. The software tries to inject packets within the network which may cause your antivirus to run haywire. So if you are really interested to have a copy, you may need to turn off your antivirus first before downloading and even during usage. In a statement from the website itself, it has been stated that:

Many anti-virus programs detect WPE Pro as a Virus or Trojan, however it is not. Some anti-virus programs will even go so far as deleting the file from your computer when you extract or, not let you run the program. To get past this, you’ll simply need to disable your anti-virus program when you plan to use WPE Pro.

I take no responsibility for your actions with WPE pro. By downloading WPE pro you hereby take all responsibility for your actions. If you have several computers on a LAN, you must make sure that you have permission from everyone on the LAN before running WPE Pro. If you do not, the program will capture all data sent on the network, breaching other’s privacy, and the law.

According to the site, this was recently updated (11 May 2011). Updates are as follows:

*UPDATE 5/22/11: New version doesn’t require use of PermEdit. Thanks goes to Devalina. *
Winsock Packet Editor (WPE) 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.

My own copy of the software can be downloaded from the link below:

(You may need to unzip the downloaded file before using.)
Here is the product description of the software taken from the website (http://wpepro.net/index.php?categoryid=2): (You may also download the copy of the software from there if you are not confident with mine):

WPE Pro Latest Version: 0.9a
Operating System: Microsoft Windows XP, Windows Vista, Windows 7

Uses

  • 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.

Example uses

  • 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.
