Researching and Remediating RCEs via GitHub Actions - Bar Kaduri, Roi Nisimi - ASW #355
Pull requests are a core part of collaboration, whether in open or closed source. GitHub has documented some of the security consequences of misconfiguring how PRs can trigger actions. But what happens when repo owners don't read the docs? Bar Kaduri and Roi Nisimi walk through their experience in reading docs, finding vulns, demonstrating exploits, and working with repo owners to improve their security. Their work highlights the challenges in maintaining good security guidance, figuring out secure defaults, and how so many orgs still struggle with triaging external security reports -- something that's becoming even more challenging when orgs are being flooded with low-quality reports from LLMs. Segment Resources: https://orca.security/resources/blog/pull-request-nightmare-github-actions-rce/ https://orca.security/resources/blog/pull-request-nightmare-part-2-exploits/ Visit https://www.securityweekly.com/asw for all the latest episodes!

Quantum Computing Isn't A Threat To Blockchains - Yet - Martha Bennett, Sandy Carielli - ASW #354
The post quantum encryption migration is going to be a challenge, but how much of a challenge? There are several reasons why it is different from every other protocol and cypher iteration in the past. Is today's hardware up to the task? Is it just swapping out a library, or is there more to it? What is the extent of software, systems, and architecture that have to be updated or replaced to complete the migration? Can we get it all done by 2030? Sandy Carielli and Martha Bennett join us to answer these questions and dive into one area of tech that hasn't been discussed much when it comes to post-quantum encryption: blockchain.

Reacting to Ransomware and Setting Secure Defaults - Rob Allen - ASW #353
Ransomware attacks typically don't care about memory safety and dependency scanning, they often target old, unpatched vulns and too often they succeed. Rob Allen shares some of the biggest cases he's seen, what they have in common, and what appsec teams could do better to help them. Too much software still requires custom configuration to make it more secure. And too few software makers are embracing secure by default, let alone secure by design. In the news, passively monitoring geosynchronous satellite communications on the cheap, successful LLM poisoning of any size model with a single size dose, security engineering lessons from Signal's post-quantum crypto work, improving security for JavaScript in the browser, and more!

Inside the OWASP GenAI Security Project - Steve Wilson - ASW #352
Interest and participation in the OWASP GenAI Security Project has exploded over the last two years. Steve Wilson explains why it was important for the project to grow beyond just a Top Ten list and address more audiences than just developers. He also talks about how the growth of AI Agents influences the areas that appsec teams need to focus on. Whether apps are created by genAI or directly use genAI, the future of securing software is going to be busy.

Finding Large Bounties with Large Language Models - Nico Waisman - ASW #351
Software has forever had flaws and humans have forever been finding and fixing them. With LLMs generating code, appsec has also been trying to determine how well LLMs can find flaws. Nico Waisman talks about XBOW's LLM-based pentesting, how it climbed a bug bounty leaderboard, how it uses feedback loops for better pentests, and how they handle (and even welcome!) hallucinations. In the news, using LLMs to find flaws, directory traversal in an MCP, another resource for learning cloud and AI security, spreadsheets and appsec, and more!
