DDoS attacks often originate externally, with bad actors looking to intentionally take your systems down. But that isn’t always the case. A poorly managed network, left unchecked, can have the same effect: preventing legitimate use of your services. Let's talk about what we mean, how to look for signs you might have unintentionally created a denial of service attack, and how to resolve the situation with OptigoVN, our free OT network monitoring and troubleshooting software. #networkmonitoring #BACnet #DDoS

At White Knight Labs, we're constantly exploring innovative techniques to enhance cybersecurity and provide top-notch training. We're excited to share a new blog post by our own Shawn Edwards titled "Sleeping Safely in Thread Pools." This post delves into an advanced use of thread pools beyond the typical process injection, focusing on their application as a safer alternative to sleeping main threads in command and control (C2) agents. This method not only mirrors tactics used by real-world adversaries but also promotes a deeper understanding of stealth operations in red team exercises. Why is this important? Despite its effectiveness and real-world application, this technique has seen limited discussion within the red team community. Our blog aims to bridge this gap, fostering greater awareness and understanding among cybersecurity professionals. Check out the blog for a comprehensive comparison between the traditional sleeping thread technique and the innovative use of thread pools. Whether you're a seasoned red teamer or just interested on the latest in cybersecurity, this piece has something for you. https://lnkd.in/eMyHj4uE #WhiteKnightLabs #CyberSecurity #RedTeam #ThreadPools #InfoSec #CyberDefense #Training

A new Denial-of-Service (DoS) attack targets application-layer protocols that draw on the User Datagram Protocol (UDP) for end-to-end communication. The newly discovered DoS loop attack is self-perpetuating and targets application-layer messages. It pairs two network services in such a way that they keep responding to one another’s messages indefinitely. In doing so, they create large volumes of traffic that result in a denial of service for involved systems or networks. Once a trigger is injected and the loop set in motion, even the attackers are unable to stop the attack. Previously known loop attacks occurred on the routing layer of a single network and were limited to a finite number of loop iterations. #DoS #network #routing

Successfully completed another lab on Partial Construction Race Condition as part of my learning journey in identifying and exploiting race condition vulnerabilities. 🚀 These scenarios highlight how simultaneous requests can expose flaws in application logic, potentially leading to critical security breaches. Always exciting to learn and stay ahead in the cybersecurity domain! 🔐 #CyberSecurity #RaceCondition #WebSecurity #Learning

I tackled the "Blind OS Command Injection with Output Redirection" lab. This exercise was an excellent deep dive into output redirection techniques and reinforced the importance of handling user inputs securely to prevent exploitation. Each new lab hones my skills in identifying and mitigating security vulnerabilities, which is crucial for keeping networks safe. Looking forward to applying these insights to real-world scenarios and exploring more advanced labs! #CyberSecurity #PortSwigger #OSCommandInjection #WebSecurity #ContinuousLearning #EthicalHacking #InfoSec

The Capture The Flag (CTF) exercise focuses on exploiting a vulnerable Domain Controller within a corporate network environment, primarily running on Active Directory (AD). Key techniques include enumerating domain users and information from Windows and Samba systems, exploiting network protocols, and understanding privilege relationships within AD environments. The exercise also highlights the importance of securing passwords and shares within the network. Privilege escalation and domain control are also highlighted, with attackers gaining access to higher-priority user accounts. The use of secretsdump.py to dump password hashes from the domain controller underscores the risk of having privileged accounts compromised. Pass the hash attacks demonstrate how attackers can authenticate as other users without knowing their actual passwords. Real-world implications of the exercise include maintaining a strong security posture, strict privilege management, strong password policies and hash security, and network segmentation and monitoring. This exercise provides valuable insights into vulnerabilities and exploitation techniques that can compromise AD environments, emphasizing the critical importance of cybersecurity measures in protecting corporate networks. Regular updates, patches, and monitoring for unusual activities are essential to prevent exploitation.
