WikiLeaks has published a new batch of documents detailing an alleged CIA project that allowed the agency to turn Windows file servers into covert attack machines that can silently infect other computers of interest inside a targeted network. Codenamed Pandemic, the tool is a persistent implant for Microsoft Windows machines that share files with remote users on a local network. Pandemic takes only 15 seconds to be installed on a target machine and can replace up to 20 legitimate files (both 32-bit and 64-bit files) at a time with a maximum file size of 800MB.
