Episode notes
Edge Targets Demand Site Knowledge
- The adversary targeted RTUs and distributed edge devices rather than centralized choke points.
- Site-specific commands require time, testing, and detailed knowledge to succeed at many distributed locations.
Rushed Preparation Reduced Impact
- Dragos judged limited impact came from incomplete preparation rather than lack of capability.
- Timing constraints likely forced a rushed operation that could not customize site commands fully.
Timing May Follow Internal Cycles
- Several past disruptive attacks clustered in December, hinting at internal timing patterns.
- Year-end reporting cycles may incentivize operations before financial or political cut-offs.
