Episode 452 - All about Meshtastic

Josh and Kurt talk about the FBI telling everyone to use end to end encrypted messengers. This is a pretty drastic deviation from messages in the past. The reason for this is it appears the US telephone networks are pwnt beyond repair at this point, which is concerning. The only real solution now is to treat the phone network as untrusted and encrypt all the traffic.

Josh and Kurt talk about a serious D-Link security vulnerability in a bunch of end of life products. The crux of the discussion focuses on D-Link, but the reality is almost all consumer gear you plug into the internet is terrible. And there's little hope it will get better anytime soon.

Josh and Kurt embark on a thought experiment to discuss how a commercial entity would handle something like the xz incident. It was very specific and difficult to understand. It's easy to claim just because source code being available doesn't matter. But the reality is when source code is needed, it can make a huge difference for everyone working together, just like we saw with xz.

Josh and Kurt talk about three government activities happening around security. CISA has a request for comment, and an international strategic plan around cybersecurity. These are both good ideas, and hopefully will help drive change. But we also discuss an EU proposal that brings liability rules to software which sounds like a great way to force change to happen.

Josh and Kurt talk about the Meshtastic open source project. It's a really slick mesh radio system that runs on very cheap radio equipment.

Josh and Kurt talk about the current Wordpress / WP Engine mess. In what is certainly a supply chain attack, the Advanced Custom Fields forking.

Josh and Kurt talk about the recent CUPS issue. The vulnerability itself wasn't all that exciting, but the whole disclosure process was wild.
