This is your Tech Shield: US vs China Updates podcast.

Buckle up, listeners—it’s Ting here, your trusted expert on all things China, hacking, and cyber defense. October has been wild in the world of Tech Shield: US vs China. If you’re wondering what’s cooking in cybersecurity this week, the answer is: a potent blend of new defenses, frantic patching, and a never-ending chess match with Beijing’s hackers.

Let’s get right to it. The sheer scale of Chinese cyber activity recently came into sharp relief thanks to Trellix’s October report. Chinese threat actors lit up the boards in April, coinciding with muscle-flexing military drills near Taiwan. So, yes, folks, Beijing’s cyber muscle is flexed right in tandem with its navy—multi-domain strategy in action. Trellix saw a spike in Chinese group activity, then a dip and leveling out, but the message is clear: US infrastructure—especially industrial and telecom—remains a prime target.

Now, what’s Team America doing in response? This week saw the Cybersecurity and Infrastructure Security Agency (CISA) work with NSA, FBI, and the Department of Defense Cyber Crime Center to push out fresh advisories warning about PRC-affiliated threat groups refining stealthy tactics. The focus: critical infrastructure hardening and urgent vulnerability scanning. They want everyone from water utilities to Silicon Valley to know—if you haven’t patched, you’re toast.

And speaking of patches, Microsoft’s update in July for the nasty ToolShell vulnerability (CVE-2025-53770) saw Chinese actors like Glowworm and UNC5221 launch attacks within two days—two days!—proving that Chinese APTs scan, adapt, and strike with breakneck efficiency. Their MO is all about stealth: using legit security tools as camouflage, slipping past industry safeguards, and sticking around for the long haul. The technical sophistication has industry CISOs sweating.

A new threat on the block is the AI-powered infostealer LameHug, attributed to APT28. It doesn’t just harvest—you guessed it—this bad boy integrates large language models to customize its intrusion on-the-fly. The US is responding with rapid innovation: quantum computing investments are ramping up, with $2.7 billion through the National Quantum Initiative Reauthorization Act and a mandate to switch to post-quantum cryptography by 2030. Startups like SEALSQ and defense giants like IBM are racing to bake quantum resilience into everything.

On the policy front, National Cyber Director Sean Cairncross says it’s time to push for a ‘clean American tech stack’ globally—to counter China’s ‘surveillance state export.’ Washington is moving past vague warnings and getting explicit. The tech industry has hopped in with regular threat simulations and resilience-by-design strategies, urged by CISA and the New York Department of Financial Services. Nobody wants to be the next headline.

But are we winning? Experts say the rush in US innovation—quantum, AI security, cross-sector drills—is promising. Yet gaps remain. Patching speed is still lagging behind adversary agility, and the sheer fragmentation of ransomware groups complicates response. The most successful strategies are those treating advanced, persistent threats as not just technical worries but strategic, ongoing business risks.
