What it detects
This rule detects a remote thread being created inside a notepad process which is the CreateRemoteThread injection step described in the WithSecure Windows lab where shellcode was written into a suspended notepad and executed. Notepad is rarely a legitimate target of cross process thread creation so this pattern is a reliable process injection indicator.
Reporting behind it
