About this episode

The episode examines “Fuxnet,” destructive malware reportedly deployed against Russian industrial sensor gateways. It remotely deletes files, disables access services, wipes routing data, rewrites flash and NAND, and floods RS485/MBUS channels with random data, bricking gateways rather than end sensors. Claroty concluded it caused widespread disruption, not true hardware destruction.
