This query hunts for the specific "reconnaissance batch" behavior observed in this campaign: a process piping netstat, systeminfo, or tasklist output into a text file (specifically a.txt as seen in the report, though looking for any single-letter text file is a good heuristic).

Detects potential exploitation of CVE-2025-49144, a local privilege escalation vulnerability in Notepad++ installers (v8.8.1 and prior) where the installer calls regsvr32.exe without specifying the full path. This allows an attacker to execute arbitrary code with elevated privileges by placing a malicious regsvr32.exe alongside this legitimate Notepad++ installer. The vulnerability is triggered when the installer attempts to register the NppShell.dll file, which is a component of Notepad++.
