xz-utils backdoor situation (CVE-2024-3094)

FAQ on the xz-utils backdoor (CVE-2024-3094)

This is a living document. Everything in this document is made in good faith of being accurate, but like I just said; we don't yet know everything about what's going on.

Update: I've disabled comments as of 2025-01-26 to avoid everyone having notifications for something a year on if someone wants to suggest a correction. Folks are free to email to suggest corrections still, of course.

Creating an SSH key with PuTTYgen for use on webOS TVs

How to Create an SSH Key for webOS with PuTTYgen

Introduction

This is a guide aimed at Windows users who want to set up public key SSH authentication for their webOS TVs. It is assumed that your TV is rooted.

This guide does not cover the Developer Mode SSH server on port 9922, although much of it still applies to that.

The SSH key that will be created can be used in applications such as PuTTY, WinSCP, and Filezilla. You'll be able to connect to your TV without having to type a password. You can even set the username in advance for one-click connections.

On other platforms (e.g., Linux), you're probably going to want to use ssh-keygen.
