Picture this.
A House Appropriations hearing room.
DHS Secretary Markwayne Mullin — yes, the same Mullin who was a Senator from Oklahoma just months ago — sitting in the hot seat.
Rep. Dan Newhouse leans into the mic.
The question is simple.
How exactly are we stopping China and Iran from walking through the back door of America's power grids, water systems, and government networks?
Mullin didn't sugarcoat it.
👉 Foreign cyber intrusions are no longer occasional.
They're constant. Coordinated. And getting smarter.
China's playbook has a name now: Volt Typhoon.
A state-sponsored group that doesn't just spy.
It pre-positions — quietly burrowing into U.S. critical infrastructure so it can flip a switch if tensions ever boil over.
Think less "hacker stealing data."
Think more sleeper cell inside the power grid.
Mullin is barely 3 months into the job.
He replaced Kristi Noem in March 2026 after a rocky stretch at DHS.
And he inherited a cyber landscape that looks like this:
🇨🇳 China — embedded in pipelines, ports, telecoms
🇮🇷 Iran — probing water utilities and financial systems
🏚️ Aging infrastructure — much of it running software older than the interns defending it
💸 Budget fights — every dollar for cyber competes with border, disaster, and immigration
Newhouse's question was really a budget question dressed up as a security question.
Are you spending enough? In the right places? Fast enough?
The old model of cybersecurity was a wall.
Build it tall. Keep bad guys out.
That model is dead.
Because the adversaries are already inside.
Living off the land. Using your own tools against you. Hiding inside routine network traffic.
Mullin's pitch to the committee was less about new walls.
More about detection, resilience, and speed of response.
Assume breach. Hunt constantly. Recover faster than they can disrupt.
This hearing won't make front-page news.
But it's the kind of moment that quietly shapes the next decade.
Because the next major conflict won't start with a missile.
It'll start with a blackout in three cities.
A water plant going offline.
A 911 system that suddenly can't answer.
And by the time anyone says the word war…
the first battle will already be over.
Mullin knows it.
Newhouse knows it.
The only question left is whether the budget — and the urgency — finally catches up to the threat.
That's all for now!
