What it detects

This rule detects conhost.exe launched in headless mode to run a bundled Node.js bootstrap script from the LogicOptimizer application directory, the execution pattern used by a ClickFix-delivered modular Windows RAT to start its gRPC-over-Tor loader. Adversaries hide the Node.js runtime behind conhost headless invocation to run attacker JavaScript without a visible console, making this a strong signal of the RAT before command-and-control is established.
