What it detects
This rule detects the Action1 RMM agent spawning a ScreenConnect client process. Threat actors daisy-chain remote management tools by using one deployed RMM to install and launch a second, giving them redundant remote access, so an Action1 process launching ScreenConnect indicates chained rogue RMM deployment rather than normal single-vendor management.
