✨ Completed "Blue" & "Ice" Rooms on TryHackMe 🔒 TryHackMe windows rooms: Blue and Ice! These warm-up challenges were perfect for practicing Windows exploitation and web misconfigurations. 🔵 Blue Exploited the infamous MS17-010 EternalBlue vulnerability. Gained a multi-managed Meterpreter shell for post-exploitation. Elevated privileges by migrating processes to NT AUTHORITY\SYSTEM. Cracked password hashes of non-default Windows users. ❄️ Ice Enumerated a poorly configured IceCast Media Server for vulnerabilities. Bypassed User Account Control UAC by exploiting Windows event viewer to take advantage of the eventvwr.exe, and the Windows registry to execute a malicious payload with elevated privileges. Leveraged Mimikatz to extract sensitive credentials from a DARK Windows user account. #CyberSecurity #TryHackMe #Pentesting #EternalBlue #PrivilegeEscalation

🔐 Understanding ZeroLogon Vulnerability: A Step-by-Step Tutorial Definition: ZeroLogon is a critical security vulnerability (CVE-2020-1472) that affects the Netlogon Remote Protocol (MS-NRPC) in Microsoft Windows. It allows an attacker to gain administrative access to a Windows domain controller and take control of the entire domain. This vulnerability was discovered and patched by Microsoft in August 2020.

#Using_Environment_Variables_for_Stealthy_Command_Execution Attackers can leverage #environment_variables to hide malicious commands and trick users or administrators. Windows environment variables, like %APPDATA% or %SYSTEMROOT%, are placeholders that point to #key_system_directories, and they’re often used in scripts and shortcuts. For example, an attacker can hide a command within an environment variable by setting it like this: set MYPATH=%APPDATA%\evil.exe %MYPATH% When run, this will execute #evil.exe from the #AppData directory without revealing the full path, making it harder to spot as malicious. Be cautious with unfamiliar environment variables in scripts or shortcuts and regularly audit custom environment variables on your system. #Cybersecurity #Windows #WindowsTips #WindowsTricks

Day 60 🔐 Active Directory Attacks & Remote Code Execution 🔐 Today's focus was on advancing lateral movement techniques and exploiting Windows systems within Active Directory environments. 🚩 Key Concepts Covered: 🔸 Active Directory Attacks - Pass The Hash (PTH): Leveraging NTLM hashes to authenticate across systems without cracking passwords. 🔸Windows RCE with psexec and wmic: Gaining remote control of systems using psexec and wmic for executing commands and achieving Remote Code Execution (RCE). 🔸 Introduction to Lateral Movement:Hands-on practice navigating and exploiting AD environments through lateral movement techniques. These practical labs are a step closer to understanding real-world attack vectors and how to defend against them! 🛡️💻 #CyberSecurity #PenTesting #ActiveDirectory #RCE #LateralMovement #EthicalHacking #OSCP #CyberAwareness

Critical Windows Security Update: 18-Month-Old Zero-Day Vulnerability Patched! 🚨 Microsoft has finally patched a high-severity Windows zero-day vulnerability (CVE-2024-38112) that cybercriminals have been exploiting for over 18 months. This MSHTML spoofing flaw allowed attackers to bypass security features and execute malicious scripts on target systems. 🔑 Key Points: This vulnerability has been actively exploited since January 2023. Attackers used specially crafted .url files to trick users into opening malicious HTA files. The flaw leveraged Internet Explorer components still present in Windows 10/11. It was used to distribute password-stealing malware like Atlantida Stealer. Microsoft's July 2024 Patch Tuesday addresses this issue by unregistering the mhtml: URI from Internet Explorer. IT administrators and Windows users should apply this critical update immediately to protect their systems from ongoing attacks. #CyberSecurity #WindowsUpdate #ZeroDay #InfoSec #Windows10 #Windows11 #Microsoft #PatchTuesday #SecurityUpdate #CyberAttack #DataProtection #Aabgm #cyberalert

🚨🚨🚨Windows Zero-Day Exploit: NTLM Credential Vulnerability via Malicious Theme Files🚨🚨 A newly discovered Windows zero-day vulnerability exploits Windows theme files to steal NTLM credentials, posing a significant security risk. Malicious theme files can force Windows to send NTLM authentication requests to remote servers when these files are previewed or copied. Attackers can use this method to execute NTLM relay or pass-the-hash attacks, potentially compromising network security and enabling lateral movement across systems . The vulnerability affects multiple Windows versions, including Windows 7 through Windows 11 24H2. ACROS Security has developed a temporary micropatch to mitigate the risk by blocking the network paths embedded in these theme files, ensuring that NTLM credentials are not leaked. Microsoft has yet to release an official patch, so users and organizations are urged to apply the available micropatch and adopt additional safeguards . To reduce exposure, consider disabling NTLM where feasible, enforcing stronger authentication mechanisms, and staying vigilant about unexpected theme files or downloads. For organizations, tools like vulnerability management platforms can assist in prioritizing and addressing such threats proactively. #CyberSecurity #ZeroDay #Windows #NTLM

🔒 Exploring the Core of Windows File Systems: NTFS 🔍 Since its debut alongside Windows NT 3.1 in 1993, the New Technology File System (NTFS) has been the backbone of Windows operating systems. With its advanced features, NTFS swiftly replaced the older FAT file system, paving the way for enhanced data management and security. Understanding NTFS is paramount for Security Operations Center (SOC) analysts, given its pervasive use in Windows environments. Delving into the intricacies of this file system not only strengthens host analysis but also empowers analysts to draw more robust security inferences. In the realm of #FilesystemForensics, delving deeper into NTFS sheds light on its structure, functionalities, and potential vulnerabilities. This knowledge equips analysts with sharper tools to safeguard systems and data against evolving threats. Let's defend our systems with knowledge! 💪 #LetsDefend #NTFS #SecurityAnalysis #CyberSecurity #Forensics #WindowsFileSystem

Part 1: Endpoint Security …………………………………......... In todays ever evolving technology, It is essential for us to understand how well we can safeguard our IT devices. Attackers can exploit vulnerabilities in an endpoint to attack an entire network. As a result, Administrators should configure endpoint operating systems to meet organisational security requiurements by: 1. limiting administrative access to system 2. Patch management (corrects security issues)- use config mgt tools to patch o/s & apps 3. System Hardening >remove unnecessary software & o/s components (reducing attack surface) > lock down the host firewall config to only allow access to those open ports & services that are intended for use. > disable default accounts & passwords that came with the software you installed > confirm windows registry & linux config settings match industry best practices. #cybersecurity #informationsecurity #infosec #networksecurity
