#Absoute #Security #is #a #myth ##CODESYS Admin panel compromised on One major clients during random Pentest. Sector- Satellite Communications :xOxO #ExploitTTP: Uploaded malicious firmware over CodeSYS firmware and gained RCE with Root privileges ! This object is used to configure the web-based display variant for remote display of the visualization of the controller in a web browser. If the CODESYS WebVisu is implemented in the ctrlX PLC app runtime environment of ctrlX CORE, the device can display graphical user interfaces on connected HTML5-capable web browsers. This can help control all functions at operator level. Security Recommendation: Protecting Your CODESYS WebVisu Panel from Exposure Here are essential security recommendations to protect your CODESYS WebVisu Panel from potential threats: 1. Network Segmentation Ensure that your CODESYS WebVisu Panel is part of a segmented network. This means separating your industrial control systems (ICS) from corporate and public networks. Use firewalls to enforce strict access controls between these segments. 2. Use VPNs for Remote Access When remote access is necessary, utilize Virtual Private Networks (VPNs) to securely connect to the internal network. This adds a layer of encryption and authentication, preventing unauthorized access. 3. Implement Strong Authentication Use strong, unique passwords for all accounts associated with the CODESYS WebVisu Panel. Enable multi-factor authentication (MFA) where possible to provide an additional layer of security. 4. Disable Unused Services Minimize the attack surface by disabling any services or features of the CODESYS WebVisu Panel that are not actively in use. This reduces the number of potential entry points for attackers. 5. Restrict IP Addresses Limit access to the CODESYS WebVisu Panel to a specific range of IP addresses. This can prevent unauthorized users from attempting to connect from unknown or unexpected locations. Conclusion The CODESYS WebVisu Panel is a powerful tool that, if left exposed, can become a target for cyberattacks. By implementing these security recommendations, you can significantly reduce the risk of unauthorized access and ensure the integrity and reliability of your industrial control systems. Stay vigilant and proactive in securing your ICS environments. 🔒 Stay Secure. Stay Vigilant. 🔒 cc Ravindra Gotavade Pascal Ackerman ..

Creating Buzz Around OSINT vs. HUMINT 🚀 OSINT vs. HUMINT: The Ultimate Intelligence Showdown! 🚀 In today's rapidly evolving digital landscape, intelligence gathering is more critical than ever. But which approach reigns supreme? 🤔 🔍 Open Source Intelligence (OSINT): Harnesses the power of publicly available information—from social media and news outlets to public records and geospatial data. It's accessible, broad, and cost-effective, but how do you sift through the noise to find the truth? 🕵️♂️ Human Intelligence (HUMINT): Relies on the age-old art of human interaction, gathering information through interviews, interrogations, and covert operations. It's deep, contextual, and adaptable, but what about the risks and costs involved? Join the conversation as we dive into the strengths and challenges of these two powerhouse methodologies! 🧠✨ cc Open Source Intelligence (OSINT.com) The OSINT Curious Project Nico Dekens (Dutch_OsintGuy) Feedbacks appreciated !
