If you have ever used a GPS to avoid traffic, you already intuitively understand the fundamental problem of computer networks. When you send a message, it needs to traverse a “web” of routers to reach its destination. But how do these devices decide where to go? Do they choose the path with the fewest cables? […]

Do you need your virtual machines (VMs) in VirtualBox to communicate with each other in isolation from your network and also isolated from the Internet? The “Internal Network” mode is the ideal solution for this scenario. Using VirtualBox in Internal Network mode is quite different from other network configuration forms in VirtualBox. For example, the

Text documents are extremely common attack vectors. Often, we receive a file that seems harmless but can hide malicious scripts (macros) or phishing links. In this tutorial, I will show how I performed a forensic analysis on an .odt (LibreOffice) file using only the Linux terminal. We will discover if the file has hidden macros,

Today, we’re going to dive into an attack tactic that, despite its simplicity and reliance on social engineering, has proven incredibly effective at bypassing defenses and achieving remote code execution (RCE): ClickFix. Popularized by researchers like John Hammond and documented in the ClickGrab project, ClickFix is a stark reminder that “layer 8” (the user) remains
