SystemBC process injection into svchost/explorer via OpenProcess+WriteProcessMemory+CreateRemoteThread
Detects cross-process activity (OpenProcess or CreateRemoteThread) targeting critical system processes (svchost.exe, explorer.exe, or rundll32.exe) from suspicious or unexpected parent processes. The rule aggregates multiple events over a short time window to reduce noise and applies a risk-based scoring system based on the injector file location.
