Wikileaks released Friday a Vault 7 document dump containing 27 documents from CIA’s Grasshopper network, a platform used to build malware payloads aimed at attacking Windows operating system devices.
“Grasshopper is provided with a variety of modules that can be used by a CIA operator as blocks to construct a customized implant that will behave differently, for example maintaining persistence on the computer differently, depending on what particular features or capabilities are selected in the process of building the bundle.
