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
SuzieQ with Dinesh Dutt and Justin Pietsch
In this episode, we talk with Dinesh Dutt, former Cisco Fellow & Cumulus Chief Scientist, and Justin Pietsch, former AWS veteran, about SuzieQ. SuzieQ is an open source network observability platform they launched last year. We talk about the general problem space of network monitoring and how the industry needs better tools to understand operational state data.

ARMs Race: Ampere Altra takes on the AWS Graviton2
Over three years ago, we embraced the ARM ecosystem after evaluating the Qualcomm Centriq. The Centriq and its Falkor cores delivered a significant reduction in power consumption while maintaining a comparable performance against the processor that was powering our server fleet at the time. By the time we completed porting our software stack to be compatible with ARM, Qualcomm decided to exit the server business. Since then, we have been waiting for another server-grade ARM processor with hopes to improve our power efficiencies across our global network, which now spans more than 200 cities in over 100 countries.
ARM has introduced the Neoverse N1 platform, the blueprint for creating power-efficient processors licensed to institutions that can customize the original design to meet their specific requirements. Ampere licensed the Neoverse N1 platform to create the Ampere Altra, a processor that allows companies that own and manage their own fleet of servers, like ourselves, to take advantage of the expanding ARM ecosystem. We have been working with Ampere to determine whether Altra is the right processor to power our first generation of ARM edge servers.
The AWS Graviton2 is the only other Neoverse N1-based processor publicly accessible, but only made Continue reading
