Summary

ReadDirectoryChanges accepts an lpCompletionRoutine which triggers the specified routine when the targeted directory content has been modified in some way (i.e., a file has been created, renamed, deleted, etc.). This can be abused to trigger a shellcode execution similar to other existing callback-based shellcode execution methods.

Either a new rule needs to be written, or a rule can be added in place of load-code/shellcode/execute-shellcode-via-windows-callback-function.yml if it is still considered within the same scope of the rule.
