This is your Dragon's Code: America Under Cyber Siege podcast.
Name’s Ting, and Dragon’s Code is running hot, so let’s jack straight into this week’s Chinese cyber ops against America’s backbone.
Over the past few days, US officials and private threat intel teams from places like Mandiant, CrowdStrike, and Recorded Future have been tracking coordinated intrusions into power grid control vendors, regional water utilities, and at least one West Coast port logistics operator. According to analysts at Mandiant, the tradecraft lines up with familiar Chinese state-linked groups like Volt Typhoon and APT41, who specialize in long‑term, low‑noise persistence inside critical infrastructure.
Here’s how they did it. First wave: classic but polished spear‑phishing, using lures spoofing Department of Energy RFP documents and Port of Los Angeles vendor contracts. The payloads dropped living‑off‑the‑land toolchains, abusing PowerShell, WMI, and signed administrative binaries, so almost no traditional malware signatures fired. Parallel to that, CrowdStrike reports a supply‑chain style compromise of a minor but widely used remote monitoring tool for industrial controllers, giving the attackers pivot points into SCADA and OT networks without touching the front door.
Once inside, they went quiet. Volt Typhoon‑style operators relied heavily on stolen credentials and VPN appliances, routing command‑and‑control traffic through compromised small business routers across the US and Europe. CISA officials say this made malicious traffic almost indistinguishable from normal admin activity. On the OT side, investigators found careful reconnaissance of IEC‑104 and Modbus devices, with read‑only access at first, suggesting pre‑positioning for future disruption rather than immediate sabotage.
Attribution hinges on a mix of infrastructure overlap, malware code reuse, and tasking patterns. According to Microsoft’s threat intel team, several command servers reused TLS certificates previously tied to Chinese state operators, and the same custom exfiltration format seen in earlier campaigns against Guam telecoms popped up again here. NSA cyber director Rob Joyce has publicly noted that the timing and target set align with Beijing’s long‑term interest in gaining leverage over US critical infrastructure during a crisis in the Pacific.
Defensively, it hasn’t been a quiet week. CISA, NSA, and FBI pushed out joint advisories, emergency directives to federal agencies to hunt for specific command‑line patterns, and new YARA rules for OT monitoring vendors. Utilities have been segmenting networks more aggressively, rolling out just‑in‑time admin credentials, and turning on deep packet inspection for those industrial protocols that used to be blindly trusted on internal links. Several ports temporarily shifted to manual fail‑safes while they validated their systems.
Lessons learned? First, in 2026 the real cyber battlefield is the boring stuff: routers in strip malls, forgotten vendor accounts, and unmanaged OT gateways. Second, attribution is getting faster, which shrinks the window for quiet persistence but escalates diplomatic tension. And third, as Jen Easterly at CISA keeps reminding everyone, defense is now a team sport: if a small water authority in Indiana doesn’t patch its remote access box, it becomes Beijing’s free pivot into the national grid.
