Definition of Module Reliability, Side Effects, and Stability

Stability

Constant	Description
CRASH_SAFE	Module should not crash the service or OS
CRASH_SERVICE_RESTARTS	Module may crash the service, but it will restart
CRASH_SERVICE_DOWN	Module may crash the service, and remain down
CRASH_OS_RESTARTS	Module may crash the OS, but it will restart
CRASH_OS_DOWN	Module may crash the OS, and remain down
SERVICE_RESOURCE_LOSS	Module causes a resource to be unavailable for the service
OS_RESOURCE_LOSS	Module causes a resource to be unavailable for the OS

Side Effects

Constant	Description
ARTIFACTS_ON_DISK	Module leaves a payload, a dropper, etc, on the target machine
CONFIG_CHANGES	Module modifies some config file
IOC_IN_LOGS	Module leaves an indicator of compromise in the log(s)
ACCOUNT_LOCKOUTS	Modules may cause an account to lock out
SCREEN_EFFECTS	Module shows something on the screen that a human may notice
PHYSICAL_EFFECTS	Module may produce physical effects in hardware (Examples: light, sound, or heat)
AUDIO_EFFECTS	Module may cause a noise (Examples: Audio output from the speakers or hardware beeps)

Reliability

Constant	Description
FIRST_ATTEMPT_FAIL	The module may fail for the first attempt
REPEATABLE_SESSION	The module is expected to get a session every time it runs
UNRELIABLE_SESSION	The module isn't expected to get a shell reliably (such as only once)
