is an encrypted archive file that serves as a cornerstone of the North Wind challenge within the SANS Holiday Hack Challenge 2023 (KringleCon). It is a forensics-focused puzzle that requires participants to extract and analyze artifacts from a compromised workstation. Overview of the Challenge

To properly "write up" or solve this artifact, the following workflow is typically used: : Inside the archive, investigators usually find: Analysis

In the "North Wind" scenario, players must investigate a suspected security breach. The .7z file is an encrypted container that holds the key to understanding the attacker's actions. The primary goal is to find the password for this archive and analyze its contents to complete the mission objectives.

: The actual payload used to establish persistence on the system. Key Findings from the Archive Forensic Tools Used 7-Zip/WinRAR : For archive extraction

: Once the password (often discovered to be NorthWind! ) is obtained, the archive can be extracted using tools like 7-Zip or p7zip .
