CSI Linux: A New Linux Distribution For Cyber and OSINT Investigation
A new cyber investigation platform has been released which is called CSI Linux.
⭕️دوستانی که با تکنیک های افزایش سطح دسترسی از نوع Potato آشنایی دارند خواهند دانست که این نوع تکنیک ها از سری تکنیک های تبدیل دسترسی سرویس به ارتقای سطح دسترسی لوکال هستند.
در هر سناریویی که یک ماشین به یک دامنه متصل میشود، تا زمانی که بتوانید کد را تحت یک حساب سرویس Windows یا یک حساب مجازی مایکروسافت اجرا کنید، میتوانید از تکنیکهای فوقالذکر برای افزایش امتیاز محلی استفاده کنید، مشروط بر اینکه اکتیو دایرکتوری امن سازی نشده باشد.
در ساختار دامین، حسابهای SYSTEM، NT AUTHORITY\NETWORK SERVICE و مایکروسافت مجازی برای احراز هویت توسط system computer account ها که به دامنه متصل شدهاند استفاده میشوند. درک این موضوع بسیار مهم است زیرا در نسخه های مدرن ویندوز، اکثر سرویس های ویندوز به طور پیش فرض با استفاده از حساب های مجازی مایکروسافت اجرا می شوند. قابل ذکر است، IIS و MSSQL از این حسابهای مجازی استفاده میکنند.
بنابراین، ما می توانیم از ابزار S4U برای دریافت TGS برای ادمین دامین یوزر"Administrator" در لوکال سیستم سوء استفاده کنیم.
که با این کار از طریق ایجاد یک سیستم سرویس، دسترسی سیستم را خواهیم داشت.
که البته قبل از این، باید یک TGT برای local machine account دریافت کنیم. به دلیل محدودیتهای اعمال شده توسط مجوزهای service account، این کار آسانی نیست، و ما را از دریافت کلید بلندمدت رایانه باز میدارد و بنابراین نمیتوانیم درخواست KRB_AS_REQ ایجاد کنیم. برای دستیابی به هدف فوق، از سه تکنیک این ابزار استفاده خواهد کرد:
Resource-based Constrained Delegation, Shadow Credentials, and Tgtdeleg

KILLER TOOL (EDR Evasion)
Features:
+ Module Stomping for Memory scanning evasion
+ DLL Unhooking by fresh ntdll copy
+ IAT Hiding and Obfuscation & API Unhooking
+ ETW Patchnig for bypassing some security controls
+ Included sandbox evasion techniques & Basic Anti-Debugging
+ Fully obfuscated (Functions - Keys - Shellcode) by XOR-ing
+ Shellcode reversed and Encrypted
+ Moving payload into hallowed memory without using APIs
+ GetProcAddress & GetModuleHandle Implementation
+ Runs without creating new thread & Suppoers x64 and x86 arch
It's a AV/EDR Evasion tool created to bypass security tools for learning, until now the tool is FUD.

Microsoft 365 MSO 2305 Build 16.0.16501.20074 Remote Code Execution (CVE-2023-28285)
The attack itself is carried out locally by a user with authentication to the targeted system. An attacker could exploit the vulnerability by convincing a victim, through social engineering, to download and open a specially crafted file from a website which could lead to a local attack on the victim's computer. The attacker can trick the victim to open a malicious web page by using a malicious Word file for Office-365 API. After the user will open the file to read it, from the API of Office-365, without being asked what it wants to activate, etc, he will activate the code of the malicious server, which he will inject himself, from this malicious server. Emedietly after this click, the attacker can receive very sensitive information!

5. Error Handling ❌ - Manages responses when things go wrong, avoiding revealing sensitive info.
6. Input Validation & Data Sanitization 🧹 - Checks input data and removes harmful parts.
7. Intrusion Detection Systems 👀 - Monitor networks for suspicious activities.
8. IP Whitelisting 📝 - Permits API access only from trusted IP addresses.
9. Logging and Monitoring 🖥 - Keeps detailed logs and regularly monitors APIs.
10. Rate Limiting ⏱ - Limits user requests to prevent overload.
11. Secure Dependencies 📦 - Ensures third-party code is free from vulnerabilities.
12. Security Headers 📋 - Enhances site security against types of attacks like XSS.
13. Token Expiry ⏳ - Regularly expiring and renewing tokens prevents unauthorized access.
14. Use of Security Standards and Frameworks 📘 - Guides your API security strategy.
15. Web Application Firewall 🔥 - Protects your site from HTTP-specific attacks.
16. API Versioning 🔄 - Maintains different versions of your API for seamless updates.
