title: Potential RipZip Attack on Startup Folder
id: a6976974-ea6f-4e97-818e-ea08625c52cb
status: test
description: |
Detects a phishing attack which expands a ZIP file containing a malicious shortcut.
If the victim expands the ZIP file via the explorer process, then the explorer process expands the malicious ZIP file and drops a malicious shortcut redirected to a backdoor into the Startup folder.
Additionally, the file name of the malicious shortcut in Startup folder contains {0AFACED1-E828-11D1-9187-B532F1E9575D} meaning the folder shortcut operation.
