December has been a rough month for Amazon—at least for Amazon Web Services. The massively popular cloud computing platform suffered its third outage of the month Wednesday, affecting Slack, the Epic Games Store, and several other services.

The AWS Service Health Dashboard shows the problem lies within a data center in northern Virginia and affects customers in the US-EAST-1 Availability Zone. The first outage was reported at 7:35 am EST.

Slack users began seeing problems shortly after the outage, and the Epic Games Store noted that the AWS outage was causing problems "affecting logins, library, purchases, etc."

    Nebula is an open source cross-platform scalable overlay networking tool with a focus on performance, simplicity and security

    Danie van der Merwe · / gadgeteerza-tech-blog · Monday, 30 August - 12:19

It lets you seamlessly connect computers anywhere in the world. Nebula is portable, and runs on Linux, OSX, Windows, iOS, and Android. It can be used to connect a small number of computers, but is also able to connect tens of thousands of computers.

Nebula incorporates a number of existing concepts like encryption, security groups, certificates, and tunneling, and each of those individual pieces existed before Nebula in various forms. What makes Nebula different to existing offerings is that it brings all of these ideas together, resulting in a sum that is greater than its individual parts.

Nebula is a mutually authenticated peer-to-peer software defined network based on the Noise Protocol Framework. Nebula uses elliptic curve Diffie-Hellman key exchange, and AES-256-GCM in its default configuration. Nebula was created to provide a mechanism for groups hosts to communicate securely, even across the internet, while enabling expressive firewall definitions similar in style to cloud security groups.

It was developed by Slack and powers their networking worldwide.

    Helpful advisory in job description

    debacle · Thursday, 27 May, 2021 - 08:00 edit

In some work environments it is - unfortunately - not yet possible to avoid the use of certain shady, non-free services. Even in the area of #freesoftware. Of course, many of us would prefer not to use #Zoom or #Slack etc.

Still, many #job description do not contain any hint, that such tools are used at work. (I'm not looking for a job, so I might have missed a new trend here.) Therefore kudos to #OTS (Open Tech Strategies) for including this warning in their job posting on the #Debian jobs mailing list:

Please note that some of our clients use proprietary communications tools, e.g., Zoom, Google Docs, Slack, etc, and therefore applicants need to be willing to use such tools when interacting with those clients.

    Slack corrige immédiatement ses Connect DM afin d’éviter le harcèlement / JournalDuGeek · Thursday, 25 March, 2021 - 11:30 · 1 minute

Crédits Slack

Il y a quelques jours, Slack déployait une série de fonctionnalités destinées à ouvrir sa messagerie intra-entreprises aux salariés travaillant pour des organisations différentes. Annoncée l’année dernière, cette nouveauté était censée permettre à n’importe qui de prendre contact avec vous directement par message direct , même sans appartenir à la même entreprise.

Des cas de cyberharcèlement rapportés

Grâce à Connect DM , l’une des nouvelles fonctionnalités déployées par Slack depuis quelques jours, il est désormais possible d’envoyer des invitations personnalisées à n’importe quel autre utilisateur de la plateforme. Seul problème, certains internautes ont rapidement rapporté des cas de cyberharcèlement via l’outil en question. En effet, les DM Connect n’intégraient aucune limite du nombre d’invitations qu’il était possible d’envoyer. De plus, le fait de personnaliser ces messages auraient conduit à quelques débordements. Une situation assez problématique, surtout qu’il n’était jusqu’alors pas possible pour l’utilisateur de filtrer ou de bloquer ces invitations, ces dernières étant envoyées via une adresse générale de Slack.

Face aux critiques des internautes, Slack a finalement décidé de prendre les devants, en modifiant rapidement la fonctionnalité DM Connect. Interrogée par The Verge, l’entreprise a ainsi expliqué par le biais de son vice-président Jonathan Prince : “Nous prenons des mesures immédiates pour empêcher ce type d’abus, à partir d’aujourd’hui. (…) Nous avons commis une erreur lors de ce déploiement initial qui est incompatible avec nos objectifs. Comme toujours, nous sommes reconnaissants à tous ceux qui ont pris la parole et nous nous engageons à résoudre ce problème”. Désormais, il n’est donc plus possible de personnaliser les messages d’invitations , et les administrateurs peuvent choisir de désactiver automatiquement les DM pour l’ensemble de leur entreprise. Un premier pas vers des conditions de travail plus apaisées.

    Slack promises to update easy-to-abuse “Connect DM” feature / ArsTechnica · Wednesday, 24 March, 2021 - 18:35 · 1 minute

Ubiquitous work-chat platform Slack this morning rolled out a new feature, Connect DM, that allows users to send direct messages to people they don't work with. Hours later, the company is already saying "our bad" and promising an update, after users demonstrated almost immediately how easy it is to use Connect DM to abuse or harass others.

Slack first rolled out Slack Connect last year, which allowed for companies to create channels shared between multiple Slack servers to facilitate business operations. Basically, if you work for Widget Film Production Inc. and you are collaborating on a project with Venue Studio Corp., Widget employees and Venue employees can both join a shared Slack channel to discuss location scouting for their upcoming project.

Today, however, Slack added a feature that allows anyone in the world with a paid account to send a direct message request to any other Slack user in the world (even if they do not have a paid account). Ilan Frank, Slack's VP of product, told tech news site Protocol that Slack is deliberately positioning itself to become the chat platform of choice for the business world. "When someone opens up their phone, if they're connecting with their friends, they click on Facebook or WhatsApp," Frank said. "If they're connecting with someone they work with, regardless of where that person works, they should be clicking on Slack."

    Update Your Slack Passwords Now, Android Users / LifehackerAustralia · Tuesday, 9 February, 2021 - 20:37 · 1 minute

Over the weekend, some Slack Android users received a seemingly random email urging them to update their passwords. The email claims a bug in the Android app incorrectly logged password data as plaintext that could be easily scooped up by hackers.

I don’t blame you if you ignored the email — it has many signs of a phishing scam — but it’s legit. Android Police confirmed with multiple Slack representatives that the emails originated from Slack, the security issues are real, and the links within the message are safe to click. While there’s no evidence passwords have been stolen or accounts hacked, Slack is proactively asking users to update their passwords.

Slack’s email includes instructions for changing your password and clearing your app cache, but it’s unclear if all affected users were alerted, so it’s wise for anyone using Slack on Android to follow the company’s suggestions, even if they didn’t get the email. Here’s what you need to do:

First, update your password with the link in Slack’s email, or under your account settings on Slack’s website.

Next, make sure you have the right version of Slack installed. This part is simple: If Slack works on your phone, you have the right version; if not, you can safely download the latest build from Google Play. Google removed the bugged version of the app from Google Play, which also disabled it on devices that had previously downloaded it, so there’s no risk in using the app anymore.

With the correct version of Slack installed on your device, the last step is to clear the app’s data cache to ensure the improperly-stored password data is removed. There are two ways to do this:

( Note: Clearing the app cache logs you out of Slack, so make sure you sign back in afterward.)

  1. In your Android settings, g o to Settings > Apps > Slack > Storage and select “ Clear Data or Storage .
  2. Long-press the Slack icon from your app launcher. Tap App Info , then Storage , then select “Clear Data or Storage.”
