What it detects
This rule detects an HTTP PUT to the vCenter VAMI endpoint /rest/appliance/access/ssh on management port 5480, matching BRICKSTORM activity that re-enables SSH on the appliance to gain shell access. Turning on this remote-access channel supports stealthy lateral movement and backdoor deployment across the virtualization estate.
