Today, May 5th 2017, WikiLeaks publishes "Archimedes", a tool used by the CIA to attack a computer inside a Local Area Network (LAN), usually used in offices. It allows the re-directing of traffic from the target computer inside the LAN through a computer infected with this malware and controlled by the CIA. This technique is used by the CIA to redirect the target's computers web browser to an exploitation server while appearing as a normal browsing session.
The document illustrates a type of attack within a "protected environment" as the the tool is deployed into an existing local network abusing existing machines to bring targeted computers under control and allowing further exploitation and abuse.

The RT provided more details:
Archimedes is an update to a tool called ‘Fulcrum’ and it offers several improvements on the previous system, including providing a method of "gracefully shutting down the tool on demand.”The Archimedes tool enables traffic from one computer inside the LAN to be redirected through a computer infected with this malware and controlled by the CIA, according to WikiLeaks.
The technique is used to redirect the target’s computer web browser to an exploitation server while appearing as a normal browsing session, the whistleblowing site said. In this way, the hackers gain an entry point that allows them access to other machines on that network.
The tool's user guide, which is dated December 2012, explains that it’s used to re-direct traffic in a Local Area network (LAN) from a "target's computer through an attacker controlled computer before it is passed to the gateway.”
This allows it to insert a false web-server response that redirects the target's web browser to a server that will exploit their system all the while appearing as if it’s a normal browsing session.
