The latest release consists of 27 documents WikiLeaks claims come from the CIA’s ‘Grasshopper framework’, a platform for building malware for use on Microsoft Windows operating systems.

In a statement from WikiLeaks, ‘Grasshopper’ was described as providing the CIA with the ability to build a customized implant which will behave differently, depending on the security capabilities of a computer.

According to WikiLeaks, Grasshopper performs “a pre-installation survey of the target device, assuring that the payload will only [be] installed if the target has the right configuration."

This allows CIA operators to detect if a target device is running a specific version of Microsoft Windows or if an antivirus is running, according to the statement.
