WebCookiesSniffer is a packet sniffer tool that captures all Web site cookies sent between the Web browser and the Web server and displays them in a simple cookies table.
The upper pane of WebCookiesSniffer displays the cookie string and the Web site/host name that sent or received this cookie.
When selecting a cookie string in the upper pane, WebCookiesSniffer parses the cookie string and
displays the cookies as name-value format in the lower pane.
- This utility works on any version of Windows, starting from Windows 2000 and up to Windows 10, including 64-bit systems.
- One of the following capture drivers is required to use WebCookiesSniffer:
- WinPcap Capture Driver:
WinPcap is an open source capture driver that allows you to capture network packets on any version of Windows.
You can download and install the WinPcap driver from this Web page.
- Microsoft Network Monitor Driver version 2.x (Only for Windows 2000/XP/2003):
Microsoft provides a free capture driver under Windows 2000/XP/2003 that can be used by WebCookiesSniffer,
but this driver is not installed by default, and you have to manually install it, by using one of the following options:
- Microsoft Network Monitor Driver version 3.x:
Microsoft provides a new version of Microsoft Network Monitor driver (3.x) that is also supported under Windows 7/Vista/2008.
The new version of Microsoft Network Monitor (3.x) is available to download from Microsoft Web site.
- You can also try to use WebCookiesSniffer without installing any driver, by using the 'Raw Sockets'
method. Unfortunately, Raw Sockets method has many problems:
- It doesn't work in all Windows systems, depending on Windows version, service pack, and the updates installed on your system.
- On Windows 7 with UAC turned on, 'Raw Sockets' method only works when you run WebCookiesSniffer with 'Run As Administrator'.
- Version 1.30:
- Added 'Auto Size Columns+Headers' option.
- Fixed bug: WebCookiesSniffer failed to remember the last size/position of the main window if it was not located in the primary monitor.
- The information of the selected network adapter is now displayed in the window title.
- Version 1.27:
- WebCookiesSniffer now automatically loads the new version of WinPCap driver from https://nmap.org/npcap/ if it's installed on your system.
- Version 1.26:
- Added 4 columns to the adapters list in the 'Capture Options' window: 'Connection Name', 'MAC Address', 'Instance ID', 'Interface Guid'.
- When using WinPCap driver , WebCookiesSniffer now displays more accurate information in the adapters list of the 'Capture Options' window.
- WebCookiesSniffer now tries to load the dll of Network Monitor Driver 3.x (NmApi.dll) according to the installation path specified in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Netmon3.
This change should solve the problem with loading the Network Monitor Driver 3.x on some systems.
- Version 1.25:
- Added 'Copy As Cookies.txt Format' option.
- Version 1.21:
- Added columns names ('IP Address' and 'Adapter Name') to the adapters list on the 'Capture Options' window.
- Version 1.20:
- WebCookiesSniffer now allows you to automatically add it to the allowed programs list of Windows firewall when starting to capture and remove it when you stop capturing. This option is needed when using the 'Raw Socket' capture method while Windows firewall is turned on, because if WebCookiesSniffer is not added to Windows firewall, the incoming traffic is not captured at all.
- WebCookiesSniffer now offers you to run it as administrator (Under Windows Vista/7/8 with UAC) if you start to capture using Raw Sockets method.
- Version 1.17:
- Added 'Copy Cookies String' option.
- Version 1.16:
- Fixed the flickering problem on Windows 7.
- Version 1.15:
- Added 'Load From Capture File' option. Allows you to load a capture file created by WinPcap/Wireshark (Requires the WinPcap driver) or a capture file created by Microsoft Network Monitor driver (Requires the Network Monitor driver 3.x) and displays the captured data in the format of WebCookiesSniffer.
- Added /load_file_pcap and /load_file_netmon command-line options.
- Fixed issue: The properties dialog-box and other windows opened in the wrong monitor, on multi-monitors system.
- Version 1.12:
- Fixed bug: When opening the 'Capture Options' dialog-box after Network Monitor Driver 3.x was previously selected, WebCookiesSniffer switched back to Raw Sockets mode.
- Version 1.11:
- Fixed the accelerator key of 'Stop Capture' (F6)
- Version 1.10:
- Added 'Start As Hidden' option. When this option and 'Put Icon On Tray' option are turned on, the main window of WebCookiesSniffer will be invisible on start.
- Version 1.07:
- Fixed bug: The check status of 'Capture On Program Start' menu item was not displayed.
- Version 1.06:
- Fixed a crash problem occurred while browsing into some Web pages.
- Version 1.05:
- Added 'Put Icon On Tray' option.
- Version 1.00 - First release.
- WebCookiesSniffer cannot capture files of a secured Web site (HTTPS)
