Helping the WayBack ArchiveTeam team: running their Warrior virtual appliance on ESXi

Posted by jpluimers on 2021/03/19

The [WayBack] Archiveteam helps the WayBack machine with feeding new content.

You can help that team by running one or more “warrior” virtual machine instances. The VM is distributed as a virtual appliance in an ova file according to the Open Virtualization Format.

That format sounds more generic than it actually is, so the (at the time of writing) archiveteam-warrior-v3-20171013.ova file at [WayBack] Index of /downloads/warrior3/ was created for VirtualBox.X

This meant running it on VMware ESXi or VMware vSphere takes a few steps for patching it, then uploading it to your VMware host.

Since I might want to run the appliance on multiple places or multiple instances, I wanted to have a ready-to-go solution, I created a git repository with both the patch instructions and the update at [WayBack] wiert.me / public / ova / archiveteam-warrior-v3-20171013.ESXi · GitLab.

Update NOW! CVE-2018-1002105, with root access. ​Kubernetes’ first major security hole discovered | ZDNet

Posted by jpluimers on 2018/12/04

From [WayBack] ​Kubernetes’ first major security hole discovered | ZDNet in reverse order:

Fortunately, there is a fix, but some of you aren’t going to like it. You must upgrade Kubernetes. Now. Specifically, there are patched version of Kubernetes [WayBackv1.10.11,  [WayBack] v1.11.5, [WayBackv1.12.3, and [WayBackv1.13.0-rc.1.

[WayBack] Red Hat said, “The privilege escalation flaw makes it possible for any user to gain full administrator privileges on any compute node being run in a Kubernetes pod. [WayBackThis is a big deal. Not only can this actor steal sensitive data or inject malicious code, but they can also bring down production applications and services from within an organization’s firewall.”

And the bug, [WayBackCVE-2018-1002105, aka the Kubernetes privilege escalation flaw, is a doozy. It’s a [WayBackCVSS 9.8 critical security hole.

Scott Hanselman on Witter: “Why should I care about Kubernetes, Docker, and Container Orchestration?”

Posted by jpluimers on 2018/02/08

An important question for many people, so if you want to know more or get started: [WayBack] Scott Hanselman on Twitter: “Why should I care about Kubernetes, Docker, and Container Orchestration?” followed by:

Yes, AKS is Azure Container Services (go figure!).

Notes

  • For burning, Scott recommends [WayBack] Etcher: Burn images to SD cards & USB drives, safely and easily (which is now also available as experimental [WayBackEtcher CLI), I tended to use a script like below since I’m a command-line person, but since Etcher does write and verify in one run, I’m considering switching:
    1. find where the SD card is mounted on your Mac: diskutil list
    2. sudo su -
    3. execute this from the directory where you downloaded filling in targetDevice with the value from diskutil list

    targetDevice="disk9"
    imageName="2017-11-29-raspbian-stretch-lite"
    unzip -o ${imageName}.zip
    diskutil umount "/dev/${targetDevice}s1"; \
    dd bs=1m of="/dev/r${targetDevice}" if=${imageName}; \
    sync; \
    diskutil list; \
    diskutil eject "/dev/${targetDevice}"
