Suspicious DLL Injection from Temporary or AppData Folders
This rule detects suspicious DLL injection activity by identifying multiple DLL loads from unusual folders such as 'Temp', 'AppData', or 'Windows\Temp'. Adversaries often drop malicious DLLs into these directories and then inject them into legitimate processes to achieve persistence, privilege escalation, or defense evasion. The rule counts the number of DLL loads from these suspicious locations by the same initiating process on the same device, triggering an alert if five or more such loads occur, indicating a concerted malicious effort.
