This is your US-China CyberPulse: Defense Updates podcast.

Listeners, Ting here with your US-China CyberPulse: Defense Updates—a whirlwind tour through the digital chessboard where the stakes are national security and the new pieces are AI, quantum, and a dash of government drama. Buckle up, because Washington’s been as busy as a script kiddie at DEF CON.

First off, if you thought China’s cyber-hustle was cooling off, think again. Sean Cairncross, the Trump administration’s national cyber director, threw down the gauntlet at the Billington Cybersecurity Summit this week. He declared China “the most aggressive” cyber adversary currently hammering away at our technology infrastructure, with attacks like the infamous Salt Typhoon and Volt proving Beijing’s capabilities are leveling up every quarter. Remember that Salt Typhoon breach? Initially eight US firms were hit, but the count keeps growing like bad source code in a legacy server.

What’s Uncle Sam doing about it? Cairncross is pushing for a whole-of-nation defense posture—and not just the usual trench-digging. Think modernizing government networks, updating the arsenal with quantum-resistant encryption, and reauthorizing the Cybersecurity and Infrastructure Security Agency Act to fast-track intelligence sharing with the private sector. If Cairncross gets his way, coordination won’t just rival China’s centralized playbook; it’ll leave Silicon Valley types feeling right at home.

But it’s not all defense—offensive hacks are getting some high-level love, too. Alexei Bulazel, a senior director at the National Security Council, says the US is “unapologetically unafraid” to go on the attack. The idea isn’t to DDoS for the headlines, but to use surgical offensive actions alongside world-class defensive tactics. Bulazel gave a shoutout to AI-powered vulnerability patching—last month, the Defense Advanced Research Projects Agency ran a competition, and the winning models patched code flaws in just 45 minutes. Not too shabby when milliseconds count.

Let’s talk about the private sector. Hanwha Systems teamed up with the American Bureau of Shipping, signing a joint research deal at Gastech 2025 in Milan to nail down US maritime cybersecurity standards. Their mission? Real-time threat detection and resilient systems for shipowners—a big leap for smart shipping when you know China’s got cyber crews probing the waves.

Meanwhile, a groundbreaking federal rule is landing October 1st. The Office of Management and Budget’s update puts most defense contractors under the Cybersecurity Maturity Model Certification microscope. If you’re not CMMC certified, you can pretty much kiss those DoD contracts goodbye—and it won’t just stop at Defense. Expect DHS and GSA to get in the game. Defense Secretary Pete Hegseth says, align your digital shields now or expect to get benched.

Internationally, the US is doubling down on trilateral defense info-sharing with Australia and Japan, aiming for seamless ISR—intelligence, surveillance, reconnaissance—and a networked, air/missile defense grid that’s harder to breach, no matter how many hackers China throws at it.

And yes, the attacks keep coming: APT41, China’s favorite state-sponsored hacking group, just targeted US trade officials with the kind of spearfishing that would make a cyber-whale jealous. Expect more targeted espionage and attempts to flip American strategy for Beijing’s gain.
