Improvements for users with disabilities: The list of handler applications in the browser settings has become accessible for screen readers. Issues have been fixed with […
It has been barely 10 years since the RoS developers (in stable 6.47) added functionality that allows DNS requests to be redirected according to specific rules. Previously, one had to convolute with Layer-7 rules in the firewall, but now it's done simply and elegantly: /ip dns static add forward-to=192.168.88.3 regexp=».*\.test1\.localdomain» type=FWD add forward-to=192.168.88.56 regexp=».*\.test2\.localdomain» type=FWD My happiness knows no bounds!

In this article, we will explore the progression not just of a machine, but of an entire mini-laboratory from the HackTheBox platform. As stated in the description, P.O.O. is designed to test skills at all stages of attacks within a small Active Directory environment. The goal is to compromise the available host, escalate privileges, and ultimately compromise the entire domain while collecting 5 flags. Connection […]

Remote learning is becoming increasingly popular for all the reasons we understand. While many Habr readers are familiar with various courses in digital specialties – software development, design, product management, etc. – the situation with lessons for the younger generation is somewhat different. There are many services for online lessons, but which one to choose? In February, I evaluated different platforms, and […]
Kubernetes is an excellent tool for running Docker containers in a clustered production environment. However, there are tasks that Kubernetes cannot address. With frequent deployment in a working environment, we need fully automated Blue/Green deployment to avoid downtime in this process, which also requires handling external HTTP requests and performing SSL offloading. This necessitates integration […]
When creating my own backup management methodology across multiple MS-SQL servers, I spent a lot of time learning the mechanism for passing values in PowerShell during remote calls, so I'm writing this reminder for myself in case it might be useful to someone else. So, let's start with a simple script and run it locally: $exitcode = $args[0] Write-Host 'Out to host.' Write-Output 'Out to […]
