WindowSpy is a Cobalt Strike Beacon Object File specifically designed for targeted user surveillance. Its primary objective is to enhance stealth during user surveillance by only triggering surveillance capabilities on specific targets such as confidential documents, browser login pages, VPN logins, among others. This not only saves time but also prevents detection of repeated use of surveillance capabilities, like screenshots. With WindowSpy, you can easily customize the list of strings to match your requirements, and the “spy()” function is highly adaptable to your preferences, allowing you to tailor your surveillance strategy as you see fit.
WindowSpy is a revolutionary tool designed to increase stealth during user surveillance by triggering surveillance capabilities only on certain targets, such as browser login pages, confidential documents, VPN logins, and more. This prevents detection of repeated use of surveillance capabilities like screenshots, and saves red teams time in sifting through excessive amounts of surveillance data produced by keylogging/screenwatch running at all times.
So how does WindowSpy work? Each time a beacon checks in, the BOF runs on the target. The BOF comes with a hardcoded list of strings that are common in useful window titles, such as “login,” “administrator,” “control panel,” “VPN,” and more. You can even customize this list and recompile the tool yourself to match your specific needs.
WindowSpy enumerates the visible windows and compares the titles to the list of strings. If any of these are detected, it triggers a local aggressorscript function defined in WindowSpy.cna named spy(). By default, it takes a screenshot, but you can customize this function to perform keylogging, WireTap, webcam access, and more.
Installation of WindowSpy is a breeze. Simply load the WindowSpy.cna script into Cobalt Strike and build from the source code, which can be easily accessed through the WindowSpy.sln solution file in Visual Studio. Then, leave it to run and it will automatically run on each beacon check-in and trigger accordingly.
WindowSpy was built by a developer who was bored and wanted to experiment with user surveillance. But don’t let its lighthearted origins fool you – this tool is incredibly powerful and highly effective. If you encounter any bugs or have any issues with the design, the developer encourages you to open an issue and they will work to resolve it.
