In a revealing publication from early September 2021, QRATOR Labs has shone a spotlight on a concerning trend: a new onslaught of DDoS (Distributed Denial of Service) attacks originating from a network of compromised MikroTik routers. This development is particularly alarming as it leverages vulnerabilities from a past security breach in 2018, which many believed had been conclusively addressed.
The complexities of MikroTik's wireless configuration can be a daunting task, especially when tasked with diagnosing and rectifying poor performing wireless networks. MikroTik RouterOS offers a plethora of configuration options, each with its own impact on network performance, reliability, and functionality. This blog post aims to demystify these settings, providing a detailed overview of the key configuration parameters within the RouterOS wireless interface menu, as outlined in the official documentation. By understanding these parameters, network administrators can fine-tune their wireless networks, ensuring optimal performance and robust connectivity.
In an unprecedented cybersecurity event, Cloudflare, a leading internet infrastructure and website security company, faced a colossal DDoS (Distributed Denial of Service) attack. This assault, known as the MikroTik Meris attack, was notable not only for its sheer volume but also for the sophistication and the type of devices exploited. In this post, we delve into the technical intricacies of the attack, the role of MikroTik devices, and the implications for cybersecurity practices moving forward.
Building reliable, high-speed wireless links is the cornerstone of delivering exceptional service to customers. This involves meticulous planning and precise execution, starting with a thorough wireless link survey. This guide will delve into the critical aspects of conducting a wireless link survey, focusing on line of sight (LoS), Fresnel zones, distance calculation, Backhaul Design Indicator (BDI), antenna selection, and the mathematics behind signal strength and potential throughput. We will use MikroTik NetMetal 5 GHz radios as our example hardware to illustrate these concepts.
A recent spotlight has been cast on MikroTik, due to its susceptibility to a series of vulnerabilities collectively known as FragAttacks. This post aims to dissect the intricacies of these vulnerabilities, delineate the affected MikroTik versions, providing insights into what these vulnerabilities expose and how users can safeguard their devices.
When utilizing MikroTik RouterBOARD wireless equipment, the choice of coaxial cable—LMR400 or LMR195—is pivotal in optimizing network performance and equipment efficiency. Given MikroTik's typically low radio power output, understanding the practical lengths for these cables, their loss per meter, and when amplification might be necessary is crucial for maintaining signal integrity and network reliability. This guide will navigate the practical applications of LMR400 and LMR195 cables in MikroTik wireless setups, focusing on optimizing your network's performance.
