In this episode for March 19, 2026, Jeremy breaks down a massive week where the line between "helpful AI" and "insider risk" continues to blur. From 87% vulnerability rates in AI-generated code to the rise of "Prompt-ware," the episode covers the accelerating operationalization of AI by both developers and nation-state adversaries.

Key Stories & Developments:

The 87% Failure Rate: Research from Dry Run Security reveals that AI agents (Claude Code, Codex, Gemini) introduce at least one security vulnerability in 87% of pull requests. Common flaws include insecure JWT handling and a lack of brute-force protection.
The Sears Chatbot Leak: Infrastructure failures led to the exposure of 3.7 million chat logs and 1.4 million audio files from Sears’ AI assistant, Samantha.
"Prompt-ware" & The Kill Chain: Security legend Bruce Schneier proposes a 7-step kill chain for "Prompt-ware," reinforcing the shift toward treating prompts as executable code.
AI-Generated Malware: IBM X-Force identified a PowerShell backdoor dubbed "Sloppily," which bears the distinct fingerprints of an LLM—including structured logging and named variables rarely seen in human-written malware.
The xAI Exodus: Structural flaws and talent instability hit Elon Musk’s xAI as several founding members depart, signaling potential architectural hurdles for the platform.
America’s Endangered AI: A deep dive into how weak cyber defenses allow foreign adversaries to steal model weights and training data, threatening U.S. tech dominance.
