The latest round of documents published by WikiLeaks as part of a leak dubbed by the organization “Vault 7” describes several tools allegedly used by the U.S. Central Intelligence Agency (CIA) to target Mac OS X and other POSIX systems.

The tools, said to be part of a CIA project named “Imperial,” are called Achilles, Aeris and SeaPea.

A “secret” document dated July 2011 reveals that Achilles is a tool that can be used to create trojanized OS X disk image installers (.dmg).
