Today, May 19th 2017, WikiLeaks publishes documents from the "Athena" project of the CIA. "Athena" - like the related "Hera" system - provides remote beacon and loader capabilities on target computers running the Microsoft Windows operating system (from Windows XP to Windows 10). Once installed, the malware provides a beaconing capability (including configuration and task handling), the memory loading/unloading of malicious payloads for specific tasks and the delivery and retrieval of files to/from a specified directory on the target system. It allows the operator to configure settings during runtime (while the implant is on target) to customize it to an operation.
According to the documentation (see Athena Technology Overview), the malware was developed by the CIA in cooperation with Siege Technologies, a self-proclaimed cyber security company based in New Hampshire, US. On their website, Siege Technologies states that the company "... focuses on leveraging offensive cyberwar technologies and methodologies to develop predictive cyber security solutions for insurance, government and other targeted markets.". On November 15th, 2016 Nehemiah Security announced the acquisition of Siege Technologies.
