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.

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.

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.

This article discusses the security of MikroTik equipment from the attacker’s perspective. Being very popular, MikroTik products are often attacked by hackers. The primary focus of this research is post-exploitation. Also, I will touch on issues plaguing RouterOS defense mechanisms that are exploited by malefactors.

Spoofing attacks are simple to deliver, and their impact is gross. This article discusses such attacks from the security perspective. The main challenge is to intelligently integrate network security solutions with production without disrupting business processes. Such integration requires a good understanding of the network and equipment specifics. In fact, this is the cornerstone of success.

Recently I discovered a new way to implement L2 tunneling against Windows networks. Inspired by the spying penguin concept, I am going to demonstrate a fresh approach to Windows post-exploitation involving a MikroTik Cloud Hosted Router (CHR) that enables you to perform pivoting and provides L2 access to the target network.

Attacks on dynamic routing domains can wreak havoc on the network since they disrupt the routing process. In this article, I am going to present my own modification of the Evil Twin attack designed to intercept data in OSPF-based networks. I will also demonstrate how to connect to an offline system, bypass authentication, and perform a malicious LSU injection.
