One of the persistence mechanisms used by the CIA here is ‘Stolen Goods’ – whose “components were taken from malware known as Carberp, a suspected Russian organized crime rootkit.” confirming the recycling of malware found on the Internet by the CIA. “The source of Carberp was published online, and has allowed AED/RDB to easily steal components as needed from the malware.”. While the CIA claims that “[most] of Carberp was not used in Stolen Goods” they do acknowledge that “[the] persistence method, and parts of the installer, were taken and modified to fit our needs”, providing a further example of reuse of portions of publicly available malware by the CIA, as observed in their analysis of leaked material from the italian company “HackingTeam”.
The documents WikiLeaks publishes today provide an insights into the process of building modern espionage tools and insights into how the CIA maintains persistence over infected Microsoft Windows computers, providing directions for those seeking to defend their systems to identify any existing compromise.
