Competent walkthrough of supply chain attack mechanics using XZ, 3CX, and VS Code extensions as anchors, with a live demo that actually lands a point. The speaker knows the material and the talk is honestly constructed, but it's fundamentally a synthesis talk — nothing here is original research, and anyone who's been paying attention since 2023 has seen these case studies dissected more deeply elsewhere.
