The Salt Typhoon Playbook: China’s Cyber Campaign Against Global Infrastructure

Bottom Line Up Front (BLUF)

A new CommandEleven series tracing China's cyber campaign against global infrastructure — from Salt Typhoon's firmware implants to the executive order it helped provoke.

On August 26, 2026, the White House declared a national emergency over foreign-sourced bulk-power equipment , explicitly naming China among the adversary nations barred from supplying transformers, inverters, and industrial control systems to the US grid. CommandEleven had already been tracking the threat pattern the order was built to address.

This series traces that pattern from the ground up: how Salt Typhoon compromised enterprise routing hardware with firmware-level implants engineered to survive reboots and administrative resets; how Mustang Panda’s evasion tooling and Operational Relay Box networks turned compromised edge devices into disposable infrastructure; and how the resulting APT ecosystem , spanning telecom networks well beyond Southeast Asia , became the evidentiary basis for a US policy response months later.
