# R-EXEC (Foreign Execution Recording Rule)

Global mapping rule: Whenever Foreign Executable Content (FEC) is interpreted, loaded, or executed, a `#7 Malware` step MUST be recorded at the moment of execution, independent of how execution was enabled. `#7` is additive (does not replace the enabling cluster).
