Lateral Movement Techniques and How to Detect Them

Introduction Lateral movement is a crucial phase in a cyberattack. After gaining initial access, attackers rarely stop there. Instead, they move sideways across the network — accessing additional systems, escalating privileges, and looking for valuable data or critical infrastructure to compromise. Understanding the techniques used for lateral movement, and knowing how to detect them, is essential for containing threats before they cause major damage. What Is Lateral

Payload Obfuscation and Evasion Techniques Used by Modern Malware

Introduction Modern malware doesn’t just infect — it deceives. As security solutions grow more advanced, so do the techniques used by attackers to evade them. Payload obfuscation and evasion are essential tools in the malware author’s arsenal, allowing malicious code to bypass antivirus, EDR, sandboxes, and even human analysis. In this article, we explore the most common and advanced techniques malware uses to stay hidden — and

Deep Analysis of a Real-World Cyberattack – How It Happened and Key Takeaways

Introduction Cyberattacks are no longer rare events—they’re a daily reality. Behind every headline is a story filled with missed warnings, clever attackers, and valuable lessons. In this article, we break down a real-world cyberattack step by step to understand exactly how it unfolded and what could have been done to stop it. Case Study: The Attack on a Mid-Sized Financial Firm Industry: FinanceEmployees: ~250Impact: Data breach, operational

Privilege Escalation Methods in Modern Attacks

Introduction Privilege escalation is one of the most critical steps in the cyber kill chain. Once attackers gain initial access—often through phishing, social engineering, or exploiting vulnerabilities—they typically have limited permissions. To cause real damage, move laterally, or access sensitive data, they need more power. That’s where privilege escalation comes into play. Understanding how attackers escalate privileges helps defenders detect suspicious behavior, block techniques, and minimize the

First Steps to Harden Your Organization’s Environment

Introduction In today’s threat landscape, small oversights can lead to massive breaches. Whether you’re a growing startup or a large enterprise, hardening your environment is one of the most effective ways to reduce your attack surface and strengthen your overall security posture. Hardening means securing systems by minimizing vulnerabilities, disabling unnecessary features, and enforcing strong controls. This guide outlines the first, most important steps any organization should

Living off the Land Attacks: What Are They and How to Defend Against Them

Introduction Cyberattacks are evolving. Rather than relying on flashy malware or easily detectable exploits, modern attackers often choose a stealthier path: using the tools already installed in your systems against you. These are known as Living off the Land attacks. In a Living off the Land attack, adversaries utilize legitimate system tools—such as PowerShell, Windows Management Instrumentation (WMI), or PsExec—to carry out malicious actions. Because these tools

EDR, XDR, and SIEM – When to Choose What

Introduction As cyber threats continue to grow in complexity and frequency, security teams are increasingly relying on advanced tools to detect, investigate, and respond to incidents. Three of the most commonly discussed solutions are EDR (Endpoint Detection and Response), XDR (Extended Detection and Response), and SIEM (Security Information and Event Management). While these technologies are often mentioned in the same breath, they serve different purposes and are

5 Signs Your Employees May Fall Victim to a Cyberattack

Introduction In today’s digital world, human error remains one of the most exploited vulnerabilities in cybersecurity. While firewalls and antivirus software are essential, the weakest link in most organizations is often the people behind the screens. Recognizing the signs that your employees may be susceptible to a cyberattack can help you take action before it’s too late. Here are five warning signs to look out for: 1.

Chasing Ghosts: How Domain Generation Algorithms Empower Stealthy Malware

Introduction What Is a DGA? In today’s threat landscape, adversaries continually refine their tactics to evade detection and maintain persistence. One such technique is the use of Domain Generation Algorithms (DGAs). By programmatically creating large numbers of pseudo-random domain names, malware can dynamically locate its command‑and‑control (C2) servers even if defenders manage to take down some of them. This article provides a concise, educational overview of DGAs:
