Firmware of popular routers often contains errors identified by security researchers on a regular basis. However, it is not enough just to find a bug – it must be neutralized. Today, I will explain how to protect your network against known and yet-unknown vulnerabilities in RouterOS.
The deplorable four. Testing free antiviruses: Huorong, Preventon, Zoner, and FS Protection
Today, I am going to battle-test four antivirus programs: a British one, a Chinese one (featuring an original engine), a Finnish one, and an exciting Czech project at the beta-version stage.

Diabolically reddish pentest. Building tunneling chains through docker containers on a Hack the Box virtual machine
How to seize control over a host located in a different subnetwork? The right answer is: build numerous intricate tunnels. This article addresses tunneling techniques and their application in pentesting using as an example Reddish, a hardcore virtual machine (insane difficulty level: 8 out of 10) available on Hack The Box training grounds.
Hack the web! Checking web sites for vulnerabilities and exploiting them
Hacking web sites is one of the most common attack types. This article is dedicated to such attacks and protection against them. I will address the pentesting basics for web applications and explain how to deal with popular web engines using real-life examples.
DDoS attacks on Bluetooth. How to disable annoying portable speakers
Gangs of teenagers with portable Bluetooth speakers playing loud music drive me nuts. Today, I will explain how to neutralize this ‘natural disaster’ without (OK, almost without) committing a criminal offense.
