Add new rule for detecting MMC spawning a shell
...
Add (analog to win_mshta_spawn_shell.yml) a dedicated rule for dedecting MMC spawning a shell. See https://github.com/Neo23x0/sigma/blob/master/rules/windows/process_creation/win_mshta_spawn_shell.yml . And it should cover the (removed) cmd part from the existing rule https://github.com/Neo23x0/sigma/blob/master/rules/windows/process_creation/win_susp_mmc_source.yml .
