US government and security officials have confirmed that China is actively conducting cyber operations against American electrical infrastructure, including backdoor implantation in power grid control systems and infiltration of the electrical supply chain. This activity represents strategic positioning to enable coercion, deterrence, or signaling during potential conflict, particularly around Taiwan contingencies. The threat is not theoretical—public reporting and government advisories document active pre-positioning of access points that could enable temporary disruption in gray-zone scenarios or larger-scale attacks during major conflict.
Defenders in the power sector should treat Chinese cyber and supply-chain exposure as a standing threat requiring integration into strategic planning. Key mitigation steps include: hardening control system equipment and network pathways, particularly for China-sourced devices; implementing rigorous vendor remote-access controls; diversifying suppliers and maintaining critical spares; and requiring security and transparency clauses in vendor contracts. The electricity sector should also conduct regular leadership-level tabletop exercises to build decision-making discipline under crisis conditions, monitor for geopolitical indicators that signal rising risk (military exercises, official narratives, vendor pressure, export controls), and share resilience best practices across the sector.

Free public brief. Slack alerts on the vendors you run come with the paid plans, and a new account gets three days of them, no card.
What this brief leaves out
This page is the free tier: the write-up, the severity, the names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,436 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
