Summary of the Pull Request

Adds missing 7zr.exe coverage to the OriginalFileName selection in the 7Zip Compressing Dump Files rule.

The rule already lists 7zr.exe under Image|endswith, but the OriginalFileName selection only included 7z.exe and 7za.exe. This creates inconsistent coverage across the executable identity fields. The change aligns OriginalFileName with the existing image-name coverage.

SigmaHQ Rule Creation Conventions

  • If your PR adds new rules, please consider following and applying these conventions

The rule work on 3 exes and has a strict OFN selection but only for 2/3, this creates a detection gap as 7zr OFN=7zr.exe.
