EASYNIGHT Propose Change

Actor(s): APT41

FireEye describes EASYNIGHT is a loader observed used with several malware families, including HIGHNOON and HIGHNOON.LITE. The loader often acts as a persistence mechanism via search order hijacking.

Examples include a patched bcrypt.dll with no other modification than an additional import entry, in the observed case "printwin.dll!gzwrite64" (breaking the file signature).
