A long time ago, in the early days of my journey to Linux kernel rootkits, I came across a Phrack article describing a rootkit detection technique implemented for i386. The article wasn’t new and referred to a vintage Linux kernel dated 2003. Something in that paper caught my attention, although much remained unclear… Ultimately, I decided to implement the anti-rootkit concept described in it for modern systems.

This article discusses Threadless Injection: a technique making it possible to make injections into third-party processes. At the time of writing, it effectively worked on Windows 11 23H2 x64 running on a virtual machine isolated from the network with OS security features enabled.

Kali Linux is extremely popular among pentesters. However, if you penetrate into a network using default settings of this distribution, it would create much noise on the air, which won’t go unnoticed. This article discusses Kali hardening and explains how to make Linux as silent as possible.

One of the main priorities for hackers is to hide the execution of their malicious code. This article explains how to start processes using the Process Ghosting technique and discusses operation principles of malware detection systems.

The modern TCP/IP protocol stack includes plenty of tunneling protocols. Normally, they are used to expand production networks and build infrastructure. But in this research, I will use them as pentesting tools.

In the course of a pentesting audit, you often have to simulate phishing attacks. This article provides a step-by-step guide to deploying infrastructure for such simulation. You will learn how to create a mail server from scratch, install and configure the Evilginx reverse proxy, and then integrate it with the Gophish phishing framework. At the end, a practical example of phishing attack is presented: you will intercept login, password, and session cookies and consequently bypass two-factor authentication.

MikroTik devices are widely used in corporate networks, but in most cases they aren’t properly configured, which opens the door to various attacks. This article discusses basic RouterOS security concepts, including protection against spoofing, traffic handling, and attacks on control panels.
