• Latest Volt Typhoon attack discovery raises concerns about OT security culture

Volt Typhoon, a threat group with links to China, had access to Massachusetts’ Littleton Electric Light and Water Departments (LELWD)’s operational technology (OT) network for ten months in 2023.

The intrusion lasted from February to November 2023, yet security researchers at Dragos, who discovered it, moved quickly once it was known; identifying the group’s activities on the server and containing the threat without customer data being compromised.
