ClickFix chokepoint: shell spawn from explorer/wt/SearchHost then egress
Detects instances where a shell process (powershell, cmd, mshta, or wscript) is spawned by a browser-related process (explorer, wt, or SearchHost) shortly after a user focuses on a web browser, followed by a network connection from that shell within a short time window. This pattern is indicative of potential web-based exploitation or file download and execution chains.
