Thu, 26 Oct 2023 13:20:49 -0700

When we think of massive compute power, we think of the Cloud when we really should consider the millions of unprotected OT devices with even greater slack computer power than all our current Cloud services combined. Sonu Shankar, Vice President of Product at Phosphorus Cybersecurity, talks about the challenge of communicating with PLCs and other devices, the risks from newer OT devices, and how all password-less OT devices really need to be protected. He says attacks aren’t just DDoS; today OT attacks can exfiltrate data as well.

EP 23: Hacking Wireless

Tue, 26 Sep 2023 15:31:58 -0700

There’s much of the electromagnetic spectrum that we cannot see. Like how LED wristbands are triggered at concerts or how to identify someone at DEF CON in a crowd of cellphones and electrical devices. Eric Escobar of SecureWorks provides some really clear analogies to help anyone visualize the differences between NFC, Bluetooth, and Wi Fi such as how your router and your microwave are both 2.4GHz - the difference is the number of watts behind each signal.

EP 22: Applying Zero Trust to OT Systems

Tue, 12 Sep 2023 12:58:09 -0700

How might we mitigate the risk to millions of unauthenticated devices already out in the field? Ron Fabela, Field CTO at XONA Systems, has some ideas about how to achieve zero trust in either legacy or new OT systems. Really, it’s just a matter of reducing the attack surface.

EP 11: Window Snyder Is Building A Secure IoT and OT Framework

Tue, 14 Mar 2023 16:36:18 -0700

We’ve already seen botnets composed of compromised devices like routers and security cameras. So how do we secure them and our smart lightbulbs too? Window Snyder, CEO of Thistle Technologies, explains how new devices can be partitioned with failovers and then serviced with regular updates all monitored from a central dashboard. Even devices already in the field today can also be upgraded and secured in some cases.

EP 10: The L0pht, According to Space Rogue

Tue, 28 Feb 2023 16:53:17 -0800

This is the story of Cris Thomas aka Space Rogue, who’s written perhaps the best book about the early days of hacking, Space Rogue: How the Hackers Known as the Loft Changed The World. Unlike a journalist merely chronicling events in Boston in the 1990s from the outside, Cris was on the inside. This is not only the story of the L0pht but it's also the story of his life, so he seamlessly provides the often missing context of the time with countless asides and anecdotes woven in instead of tacked on. In this episode of Error Code, Cris also drops a lot of names.

EP 09: Zhadnost

Tue, 14 Feb 2023 16:39:51 -0800

This is the story of Zhadnost, of how an IoT-based botnet was conscripted into an online war in the days immediately before the kinetic Ukraine invasion.
