In Macedonia, Strengthening IXP.mk’s Peering Infrastructure
The Internet Society has been supporting the development of the Internet in Macedonia by collaborating with the Faculty of Computer Science and Engineering (FCSE) of the Saints Cyril and Methodius University in Macedonia on its IXP.mk project. IXPs play a critical role in bringing faster and more affordable Internet, and the Macedonian IXP (IXP.mk) had been established in June 2018 with technical support from a number of stakeholders.
Switch and MUX to Strengthen Infrastructure
As traffic grew, IXP.mk needed to increase its peering capacity with improved switching capabilities and space for data racks that would allow it to attract new participants to the exchange. In 2020, the Internet Society provided IXP.mk with a switch and two Fiber Optic Multiplexers (Fiber Mux) that enabled an additional peering location to be established in the Telesmart Telekom data center, thereby making it easier for other major networks and Content Distribution Networks to peer with each other. The Fiber Muxes support the transmission of multiple data channels over a single fiber that has been donated by an existing member of IXP.mk.
Critical Service Provider
With a strong peering infrastructure, IXP.mk is now a critical service provider to Continue reading
Lessons Learned from Scaling Up Cloudflare’s Anomaly Detection Platform
Introduction to Anomaly Detection for Bot Management
Cloudflare’s Bot Management platform follows a “defense in depth” model. Although each layer of Bot Management has its own strengths and weaknesses, the combination of many different detection systems — including Machine Learning, rule-based heuristics, JavaScript challenges, and more — makes for a robust platform in which different detection systems compensate for each other’s weaknesses.
One of these systems is Anomaly Detection, a platform motivated by a simple idea: because bots are made to accomplish specific goals, such as credential stuffing or content scraping, they interact with websites in distinct and difficult-to-disguise ways. Over time, the actions of a bot are likely to differ from those of a real user. Anomaly detection aims to model the characteristics of legitimate user traffic as a healthy baseline. Then, when automated bot traffic is set against this baseline, the bots appear as outlying anomalies that can be targeted for mitigation.
An anomaly detection approach is:
- Resilient against bots that try to circumvent protections by spoofing request metadata (e.g., user agents)
- Able to catch previously unseen bots without being explicitly trained against them.
So, how well does this work?
Today, Anomaly Detection processes more than Continue reading
Video: Cisco SD-WAN Routing Design
After reviewing Cisco SD-WAN policies, it’s time to dig into the routing design. In this section, David Penaloza enumerated several possible topologies, types of transport, their advantages and drawbacks, considerations for tunnel count and regional presence, and what you should consider beforehand when designing the solution from the control plane’s perspective.

The Hedge #74: Brian Keys and the Complexity of User Interfaces
Crossing from the domain of test pilots to the domain of network engineering might seem like a large leap indeed—but user interfaces and their tradeoffs are common across physical and virtual spaces. Brian Keys, Eyvonne Sharp, Tom Ammon, and Russ White as we start with user interfaces and move into a wider discussion around attitudes and beliefs in the network engineering world.
Deconstructing Defray777 Ransomware
Contributors: Sebastiano Mariani • Stefano Ortolani • Baibhav Singh • Giovanni Vigna • Jason Zhang • Brian Baskin • George Allen • Scott Knight
Recently, reports surfaced describing ransomware attacks targeting VMware ESXi servers. While many of these attacks were initially based upon credential theft, the goal was to unleash one of a series of ransomware families, including Defray777 and Darkside, to encrypt the files associated with virtualized hosts.
These families of ransomware are related to examples that the VMware Threat Research teams had seen previously in the wild. Specifically, based upon their ransom notes and file extensions, they appeared to be variants of the RansomEXX ransomware family. In the second half of 2020 these variants of ransomware, including Defray777, have been witnessed targeting both Windows and Linux systems.
These attacks also leveraged several ancillary tools such as downloaders, RATs, and exploitation tools to obtain initial access to a system and spread within the target network.
In the following, we provide a technical description of the Defray777 ransomware and a brief discussion of the other components that have been observed in combination with this malware sample.
What is Defray777?
The version of Defray777 analyzed here is a Linux-based, command-line driven ransomware attack that employs Continue reading
