Description

The following analytic detects modifications to the Windows Registry specifically targeting `.pwn` file associations related to the ValleyRAT malware. ValleyRAT may create or alter registry entries to associate `.pwn` files with malicious processes, allowing it to execute harmful scripts or commands when these files are opened. By monitoring for unusual changes in registry keys linked to `.pwn` extensions, this detection enables security analysts to identify potential ValleyRAT infection attempts. Early detection of these modifications helps mitigate unauthorized execution and prevents further exploitation of the system.
