[Vulnerability Type] XML External Entity Injection [ZDI Reference] ZDI-CAN-6307 [Security Issue] Microsoft Baseline Security Analyzer allows local files to be exfiltrated to a remote attacker controlled server if a user opens a specially crafted „.mbsa“ file.

CVE-2025-24054, NTLM Exploit in the Wild

NTLM hashes dumped from Active Directory are cracked at a rate of over 715 Billion guesses per second. For comparison’s sake, the laptop I am writing this from has a single Nvidia Quadro M1000M GPU, that cracks hashes at a rate approximately 150 times slower than Cthulhu.

Technical Explanation of NTLM Hash Leak The .library-ms file format is XML-based and trusted by Windows Explorer to define search and library locations. When a specially crafted .library-ms file containing an SMB path is extracted from a compressed archive, Windows Explorer attempts to resolve this path automatically to gather metadata and index file [Vulnerability Type] XML External Entity Injection [ZDI Reference] ZDI-CAN-6307 [Security Issue] Microsoft Baseline Security Analyzer allows local files to be exfiltrated to a remote attacker controlled server if a user opens a specially crafted The NTLM system takes your actual password, processes it into a “hash”—sort of like putting your lunch in a blender—and then uses that hash to verify your identity.

Before we can extract anything from the SAM database, we have to consider what we’re looking for. Windows stores passwords as an MD4 hash of the plaintext password, called the NT hash. During the login process, the LSA hashes the provided password and compares it to the NT hash stored in the SAM database.

Extracting hashes from Windows systems is a critical skill for cybersecurity professionals, penetration testers, and digital forensic analysts. Hashes such as NTLM and Kerberos play a central role in Windows authentication mechanisms, and understanding how to extract and analyze them is essential for both offensive and defensive security operations.

This website allows you to decrypt, if you’re lucky, your ntlm hashes, and give you the corresponding plaintext, you can also encrypt any word using the NTLM hash generator. Updated on April 22, 2025 NT LAN Manager (NTLM) is a Microsoft authentication protocol used to verify user identities in Windows networks. While it was once a key part of Windows authentication, NTLM is now outdated due to security weaknesses and the availability of stronger options like Kerberos. However, it’s still important for IT professionals to understand NTLM This Tech Tip outlines what enterprise defenders need to do to protect their enterprise environment from the new NTLM vulnerability.

XXE（XML External Entity）攻撃とは、XMLパーサが外部エンティティの参照を許可している場合に発生する脆弱性を悪用した攻撃です。 Windows Credential Harvesting Quick Guide December 11, 2022 This post will cover some common scenarios on how to collect, dump and decrypt windows credentials – specifcally NTLM and MsCacheV2. Targeted to be a non-exhaustive cheat sheet. Well, the NTLM Hashing Algorithm produces the NT Hash/NTLM Hash and the NTLM Authentication Protocol also produces a hash but this one is referred to as the Net-NTLMv1/v2 Hash.

Online hash tools is a collection of useful utilities for cryptographically hashing data. All hash tools are simple, free and easy to use. There are no ads, popups or other garbage, just hash functions that work right in your browser. And all utilities work exactly the same way — load data, get a hash. Created by team Browserling. Mimikatz is a tool that can allow you to extract all kinds of Windows secrets. In this post I will show you how to dump password hashes from a SAM database. ntlm_theft A tool for generating multiple types of NTLMv2 hash theft files. ntlm_theft is an Open Source Python3 Tool that generates 21 different types of hash theft documents. These can be used for phishing when either the target allows smb traffic outside their network, or if you are already inside the internal network.

In this guide on NTLM, Microsoft’s authentication protocol, we explore its three-step process and delve into various attacks like ‚Pass the Hash‘ and NTLM Relay. Techniques like reconnaissance, credential validation, and hash retrieval are examined, highlighting NTLM’s role in network security. Preface: If you want to decrypt a writeup for an active windows box on HTB or from other plattforms using the NTLM hash of the administartor user, you are on the right place. In this How-To post I will show you how you can extract the NTLM hash of the administrator user (probably for any user) on windows machines.

CVE-2025-24054 is a vulnerability related to NTLM hash disclosure via spoofing, which can be exploited using a maliciously crafted .library-ms file. Active exploitation in the wild has been observed since March 19, 2025, potentially allowing attackers to leak NTLM hashes or user passwords and compromise systems. XML external entity (XXE) injection In this section, we’ll explain what XML external entity injection is, describe some common examples, explain how to find and exploit various kinds of XXE injection, and summarize how to prevent XXE injection attacks.
