This is your China Hack Report: Daily US Tech Defense podcast.

I'm Ting, your daily byte-sized guide to the whirlwind of China-linked cyber intrigue, where every sunrise brings another volley of hacks, patches, and eyebrow-raising headlines. So, July 3, 2025—strap in, because the last 24 hours have been wild.

First, big news in broadband: Salt Typhoon—the latest name to haunt the dreams of CISOs—is still making headlines. Yesterday, investigators sounded the alarm after discovering that Chinese state-backed hackers had compromised networks at Verizon, AT&T, and Lumen Technologies. These weren’t just any networks: they’re the backbone for federal court data and the systems used to facilitate court-ordered wiretaps. That means sensitive law enforcement communications may have waltzed straight into Beijing’s arms, and other slices of internet traffic, too. How long were they in? Investigators say possibly months. China, for its part, denies everything, with their foreign ministry accusing the US of “concocting a false narrative.” Classic[2].

Meanwhile, CISA has gone full DEFCON mode. Their emergency advisory late last night urges all telecom and critical infrastructure providers to scour network logs for indicators of compromise tied to Salt Typhoon’s toolkit and to apply the latest firmware and software patches ASAP. They’re mandating password resets for privileged accounts and recommending full review of any system connected to law enforcement workflows.

Now, on the malware front, fresh reverse engineering from multiple security firms has unearthed a Volt Typhoon variant. This malware leverages zero-day flaws to bypass traditional security and is built for silent persistence inside US infrastructure. If Volt Typhoon sounds familiar, it should—China admitted last year at a hush-hush Geneva summit that they conducted these attacks, which targeted energy, communications, manufacturing, and transportation sectors. Back in 2023, they lurked in the US electric grid for a jaw-dropping 300 days. Their purpose? US officials believe it was to spook Washington away from supporting Taiwan by showing just how deeply they could burrow into critical systems[1].

And it isn’t just power grids and telecoms in the crosshairs. A recent state-sponsored attack on the US Treasury Department—especially the Office of Foreign Assets Control—marks an escalation in China’s hybrid warfare toolkit, mixing cyber espionage with economic pressure. The Department of Defense’s latest threat assessment makes it clear: China is pre-positioning itself to take down or disrupt US critical infrastructure if a major conflict looms, especially over Taiwan[3][4].

So, here’s Ting’s cheat sheet:
- Patch now—especially if you’re in telecom, government, or energy.
- Audit privileged accounts and law enforcement-related systems for signs of intrusion.
- Watch for new CISA bulletins—this is a rapidly evolving threat.

Stay sharp, folks. The firewall is only as strong as the sysadmin behind it. I’ll be back tomorrow with more cyber drama—same time, same tunnel.
