On 27 February 2020, MalwareMustDie (MMD), a workgroup focused on the research and study of Linux malware, analysed and shared a new type of malware they called RHOMBUS. This malware was compiled for different architectures, had persistence mechanisms and dropped a second-stage payload. —Lisandro Ubiedo

Security researchers witnessed the deployment of PonyFinal ransomware at the end of extended human-operated attack campaigns. In a series of tweets, Microsoft Security Intelligence revealed it had observed human-operated campaigns laying in wait for the right moment to deploy PonyFinal ransomware as their final payload. —David Bisson

NetWalker (also known as Mailto) is the name given to a sophisticated family of Windows ransomware that has targeted corporate computer networks, encrypting the files it finds, and demanding that a cryptocurrency payment is made for the safe recovery of the encrypted data. —Graham Cluley

Memory isolation is a cornerstone security feature in the construction of every modern computer system. Allowing the simultaneous execution of multiple mutually distrusting applications at the same time on the same hardware, it is the basis of enabling secure execution of multiple processes on the same machine or in the cloud. The operating system is in charge of enforcing this isolation, as well Continue reading

Attention Resource Deficit

How much did your last laptop cost? You probably know down to the penny. How much time did it take for you to put together your last Powerpoint deck or fix an issue for a customer? You can probably track that time in the hours you recorded on your timesheet. What about the last big meeting you had of the department? Can you figure out how many hours combined of time that it took to get the business discussed? Pretty easy to calculate when you know how many people and how long it took.

All of these examples are ways that we track resources in the workplace. We want to know how many dollars were invested in a particular tool. We want to figure out how many hours someone has worked on a project or a proposal. We want to know how much of the company’s resources are being invested so we can track it and understand productivity and such. But when’s the last time you tracked your personal resources? I’m not talking about work you do or money you spend. I’m talking about something more personal than that. Because one of the things that I’ve seen recently that is Continue reading

How we use HashiCorp Nomad

In this blog post, we will walk you through the reliability model of services running in our more than 200 edge cities worldwide. Then, we will go over how deploying a new dynamic task scheduling system, HashiCorp Nomad, helped us improve the availability of services in each of those data centers, covering how we deployed Nomad and the challenges we overcame along the way. Finally, we will show you both how we currently use Nomad and how we are planning on using it in the future.

Reliability model of services running in each data center

For this blog post, we will distinguish between two different categories of services running in each data center:

Customer-facing services: all of our stack of products that our customers use, such as caching, WAF, DDoS protection, rate-limiting, load-balancing, etc.
Management services: software required to operate the data center, that is not in the direct request path of customer traffic.

Customer-facing services

The reliability model of our customer-facing services is to run them on all machines in each data center. This works well as it allows each data center’s capacity to scale dynamically by adding more machines.

Scaling is especially made easy thanks to Continue reading

Video: Public Cloud Networking Overview

Donal O Duibhir was trying to get me to present at INOG for ages, and as much as I’d love to get to Ireland we always had a scheduling conflict.

Last week we finally made it work - unfortunately only in a virtual event, so I got none of the famous Irish beer - and the video about alternate universes of public cloud networking is already online.

Maximilian Wilhelm had great fun turning my usual black-and-white statements into tweets, here’s a selection of them:

DevAsc – Introduction to JSON

Introduction

JSON, JavaScript Object Notation, is one of the usual suspects when it comes to network automation. YAML and XML being the other two. It’s easy for machines to parse and generate and the readability is good, better than XML, although YAML is easier for humans to read.

JSON is based on a subset of the JavaScript programming language, as the name implies.

JSON, just like YAML, supports single values, lists, and key/value pairs.

JSON is commonly used to interchange between different formats.

Syntax

JSON has no requirement for indentation or white space, which YAML has. That said, to make it human readable, it still makes sense to use white space and spaces, most likely either two or four.

Strings MUST use double quotes
Object literal names MUST be lowercase (null, false, true etc)
Special characters need to be escaped
{ says “begin object”
} says “end object”
[ says “begin array”
] says “end array”
: separates key and value in key/value pair
, separates key/value pair in an object or separates values in an array, think of it as “expect another one”

Data Types

JSON supports the following data types:

Object
String
Number
Boolean
Null
Array

We’ll Continue reading

Cisco issues fixes for numerous iOS XE, industrial router vulnerabilities

Cisco has unleashed an extensive new round of security warnings – three of them “critical” – mostly for users of its iOS XE software and industrial router family.In total, Cisco issued 23 Security Advisories that describe 25 exposures in its IOS and IOS XE systems. Network pros react to new Cisco certification curriculum Beyond the three critical advisories, 20 have a “High” impact rating. Cisco said that one vulnerability affects Cisco IOS, IOS XE, IOS XR, and NX-OS Software. Five vulnerabilities affect both Cisco IOS and IOS XE Software. Six vulnerabilities affect Cisco IOS Software and 10 affect Cisco IOS XE Software. Three vulnerabilities affect the Cisco IOx application environment.To read this article in full, please click here

Startup lands $100 million to build floating data centers

Data centers and water seem to go together, despite the fact water is bad for electronics. Many hyperscale data centers are built near rivers for use as hydroelectric power sources, liquid cooling is growing in popularity, and in one extreme case, Microsoft sunk a mini data center off the coast of northern England.The next step, it seems, is the floating data center, one on the water and easily accessible but also mobile. A startup called Nautilus Data Technologies has lined up $100 million in funding to build a six-megawatt floating colocation facility that it says will be cheaper and more efficient than traditional facilities.To read this article in full, please click here

Making Intermediaries Liable for Encrypted Content Breaks Trust and Security

In December 2018, the Indian Ministry of Electronics & Information Technology (MeitY) proposed a significant change to its intermediary rules. The draft Information Technology [Intermediaries Guidelines (Amendment) Rules] 2018 seeks to tie tech platforms’ (e.g., social media) protections from liability to an obligation to monitor and filter their users’ content. One of the proposed obligations is to ensure the traceability of messages, even if a service is end-to-end encrypted.

India is just one of many countries around the world experimenting with the idea that Internet intermediaries – specifically social media companies, like Facebook and Twitter – should no longer have immunity from liability for the content shared by their users. Other examples include the U.S. Eliminating Abusive and Rampant Neglect of Interactive Technologies Act of 2020 (the EARN IT Act), and the recent U.S. Executive Order on Preventing Online Censorship.

The motivation for changing the status quo varies, from wanting traceability of messages to counter the spread of disinformation or CSEM, to stopping objectionable content from being spread on social media, to preventing political messages from being labeled (e.g., as “misleading information”). Similarly, the approaches being considered to achieve this vary, ranging from Continue reading
