“Keystone is part of the Wolfcreek implant and responsible for starting malicious user applications. Loaded implants never touch the file system, so there is very little forensic evidence that the process was ever ran.”

This link by "Q" suggests to me that this now top dog for "keystone" ... I still like others considered but this is a significant indicator IMO.

Agree, except that if Q and his team are using that “keystone” to keep track of the deep state, you would think it would be far above top secret, not something to talk about on 8 Chan.
