This is your Cyber Sentinel: Beijing Watch podcast.

Hey, folks! Ting here, your sharp-witted cyber sleuth, ready to unpack the wild world of digital espionage in this week’s Cyber Sentinel: Beijing Watch. If you’ve ever wondered what Beijing’s cyber warriors have been up to lately, buckle up. The past several days have been a whirlwind of attacks, geopolitical jabs, and shifting strategies—so let’s cut straight to it.

First, let’s talk new tricks and attack methodologies. The Chinese-linked APTs—think Volt Typhoon and Salt Typhoon—are not just ghosting through email inboxes anymore. They’ve been burrowing into U.S. critical infrastructure networks, especially energy and water, not for a quick smash-and-grab but to build persistence, perhaps quietly setting the chessboard for more disruptive attacks down the line. Security folks have noted these groups employing “living off the land” tactics, blending into normal system operations to evade alarms. It’s less Mission Impossible lasers-and-rope and more like your nemesis quietly moving furniture at night so you trip in the morning.

Industries in the crosshairs? Think broad: utilities, shipping, logistics (where there’s already been a spike in invoice fraud), and defense supply chains. With the recent U.S. tariff hikes, cyber advisors like Tom Kellermann are warning that China is likely to escalate attacks as an asymmetrical response. So if you’re running SCADA systems or handling sensitive trade data, this is not the time to ignore those system alerts.

How do we know these are Beijing’s fingerprints? Apart from the technical signatures pointing squarely to Volt Typhoon and Salt Typhoon, Chinese officials reportedly told the Biden administration back in December 2024 that they were behind some of these intrusions. That’s attribution with a side of bravado. And let’s not forget the 12 Chinese contract hackers and law enforcement officers charged by the DOJ in March—another breadcrumb trail leading to state-sponsored hacking campaigns.

International responses are heating up. The White House, with Alexei Bulazel leading cyber policy, has signaled readiness for retaliatory cyber strikes if China crosses certain lines. The “Strengthening Cyber Resilience Against State-Sponsored Threats Act” is back on the legislative docket, aiming to harden critical infrastructure and track Chinese infiltration. Meanwhile, Republican lawmakers are pushing for more federal resources and sharper oversight.

So, what’s a sensible defender to do? Tactically: monitor for unusual lateral movement, double-check remote access credentials, and tighten up on phishing susceptibility. Strategically: map your supply chain dependencies and assume your critical infrastructure partners are being probed as well. The game is about resilience, not just defense—detect, recover, and disrupt adversary footholds before they escalate.

Looking forward, China’s cyber posture is shifting from pure espionage to potential pre-positioning for sabotage. As trade and Taiwan tensions rise, expect Beijing’s digital claws to get sharper—and keep your playbooks ready to adapt. That’s it for this week; this is Ting, signing off but never offline!
