Since Wikileaks began releasing classified CIA documents back in March as part of its “Vault 7” series of leaks, purportedly the largest document dump in the agency’s history, it has publicly unveiled programs with innocent sounding names like “Marble”, “Scribbles” and “Archimedes” that the agency employs to help execute its operations, or to cover its tracks.
On Thursday, the group released the 19th installment in its series by publishing a series of documents detailing how the agency uses a custom-designed hacking exploit called “Dumbo” to destroy, or manufacture, evidence during field operations, according to a Wikileaks press release.
The CIA filed a request that such a tool back in 2012, according to a powerpoint presentations describing what capabilities it would need.
“Dumbo works by discovering which processes have access to the physical camera device and uses that information to corrupt video files. In some instances, programs emulate a camera input to other programs; such is the case with Fujitsu’s YouCam.exe. When this occurs, YouCam.exe will have control of the actual webcam, and feed input to other processes that record images to files as needed. In this scenario, Dumbo will suspend YouCam.exe but will not be able to detect the other processes to which YouCam.exe is feeding images. Although the camera will not be able to record additional frames, Dumbo will not be able to corrupt files that were written to prior, as it is unaware of the processes writing the video files. If the operator sees a process using the camera device, but Dumbo detects no files being written, the operator should manually search for video files.
In some instances, video recording software has the ability to detect it is not responding, and will restart itself; such is the case with iSpy.exe. When Dumbo detects a process using a camera device, it also claims control of the device. If the recording software were to restart itself, it would no longer be able to access the camera until Dumbo exits. In the case of iSpy,although the program may restart, it will be unable to record any additional frames; it will appear as if it was unable to access the camera, due to it already being in use.”

Realist - Everybody in America is soft, and hates conflict. The cure for this, both in politics and social life, is the same -- hardihood. Give them raw truth.
