About this episode

This episode discusses recent vulnerabilities found in the BEAM ecosystem and the evolving landscape of security research.

The BEAM ecosystem spent decades flying under the radar - too niche to attract serious attackers. That era is over. In this episode, we sit down with Peter Ullrich, the developer who ran a $10 experiment at ElixirConf EU in Málaga and discovered a vulnerability that could crash the BEAM with a 13-character string - with zero prior security experience. Then we hear from Jonathan Machen, CISO of the Erlang Ecosystem Foundation, whose job is to catch and coordinate everything Peter finds. We cover: How Peter built a simple bash script that scanned the most-downloaded Hex packages - and what he found Why LLMs have changed the cost and skill floor for vulnerability research forever The CVE disclosure process: what happens from the moment a bug is found to the moment it's published How the EEF's CNA went from 9 CVEs in a year to more in a single week What library maintainers should do right now (spoiler: it's three clicks on GitHub) The AGES initiative, supply chain security, and the gap between what's been built and what the moment demands Why paying a vendor like Trivy isn't enough - and what actually needs to happen If you run Phoenix in production, this episode is required…
