Segment 1: Interview with Rob Allen It’s the Year of the (Clandestine) Linux Desktop! As if EDR evasions weren’t enough, attackers are now employing yet another method to hide their presence on enterprise systems: deploying tiny Linux VMs. Attackers are using Hyper-V and/or WSL to deploy tiny (120MB disk space and 256MB memory) Linux VMs to host a custom reverse shell and reverse proxy. In this segment, we’ll discuss strategies and mitigations to battle this novel technique with Rob Allen from Threatlocker. Segment Resources: This segment is sponsored by ThreatLocker. Visit to...

Segment 1: OT Security Doesn’t Have to be a Struggle OT/ICS/SCADA systems are often off limits to cybersecurity folks, and exempt from many controls.

In this interview, we discuss the challenge of securing OT systems with Todd Peterson and Joshua Hay from Junto Security. This segment is sponsored by Junto Security. Visit to learn more!

Segment 1: David Brauchler on AI attacks and stopping them David Brauchler says AI red teaming has proven that eliminating prompt injection is a lost cause.

NCC Group’s AI security team has surveyed dozens of AI applications, exploited their most common risks, and discovered a set of practical architectural patterns and input validation strategies that completely mitigate natural language injection attacks....

info_outlineInterview Segment - Lessons Learned from the tj-actions GitHub Action Supply Chain Attack with Dimitri Stiliadis
Breach analysis is one of my favorite topics to dive into and I’m thrilled Dimitri is joining us today to reveal some of the insights he’s pulled out of this GitHub Actions incident. It isn’t an overstatement to say that some of the lessons to be learned from this incident represent fundamental changes to how we architect development environments.
Why are we talking about it now, 4 months after it occurred? In the case of the Equifax breach, the most useful details about the breach didn’t get released to the public until 18 months after the incident. It takes time for details to come out, but in my experience, the learning opportunities are worth the wait.
Topic Segment - Should the US Go on the Cyber Offensive?
Triggered by an op-ed from Dave Kennedy, the discussion of whether the US should launch more visible offensive cyber operations starts up again. There are a lot of factors and nuances to discuss here, and a lot of us have opinions here. We'll see if we can do any of it justice in 15 minutes.
