The most dangerous vulnerability you've never heard of. In the world of cybersecurity, vulnerabilities are discovered so often, and at such a high rate, that it can be very difficult to keep up with. Some vulnerabilities will start ringing alarm bells within your security tooling, while others are far more nuanced, but still pose an equally dangerous threat. Today, we want to discuss one of these more nuanced vulnerabilities as it is likely lurking in your environment waiting to be exploited: Active Directory Certificate Services vulnerabilities.  vPenTest by Vonahi Security recently implemented an attack vector specifically designed to identify and mitigate these hidden AD CS threats. But first, let's explore why AD CS vulnerabilities are so dangerous and how they work. What is Active Directory Certificate Services? Active Directory Certificate Services ("AD CS"), as defined by Microsoft is, "a Windows Server role for issuing and managing public key infrastructure (PKI) certific

Network penetration testing plays a crucial role in protecting businesses in the ever-evolving world of cybersecurity. Yet, business leaders and IT pros have misconceptions about this process, which impacts their security posture and decision-making.  This blog acts as a quick guide on network penetration testing, explaining what it is, debunking common myths and reimagining its role in today's security landscape.  What is network penetration testing? Network penetration testing  is a proactive approach to cybersecurity in which security experts simulate cyberattacks to identify gaps in an organization's cyberdefense. The key objective of this process is to identify and rectify weaknesses before hackers can exploit them. This process is sometimes called "pentesting" or "ethical hacking."  Network pentesting checks for chinks in an organization's armor to help mitigate cyber-risks and protect against data, financial and reputational losses.  Differe

For years, securing a company's systems was synonymous with securing its "perimeter." There was what was safe "inside" and the unsafe outside world. We built sturdy firewalls and deployed sophisticated detection systems, confident that keeping the barbarians outside the walls kept our data and systems safe. The problem is that we no longer operate within the confines of physical on-prem installations and controlled networks. Data and applications now reside in distributed cloud environments and data centers, accessed by users and devices connecting from anywhere on the planet. The walls have crumbled, and the perimeter has dissolved, opening the door to a new battlefield: identity . Identity is at the center of what the industry has praised as the new gold standard of enterprise security: "zero trust." In this paradigm, explicit trust becomes mandatory for any interactions between systems, and no implicit trust shall subsist. Every access request, regardless of its origin,
