Chinese Hackers Gone Wild: Infrastructure Under Siege as Beijing's Cyber Goons Run Amok

This is your Digital Frontline: Daily China Cyber Intel podcast.

Ting here, your guide on the wild ride that is the Digital Frontline. The last 24 hours have been a cyber-action movie, with Chinese state-sponsored hackers starring as the villains and nearly every major US sector popping up in their crosshairs. Let’s plug in.

First up: an intelligence thunderclap hit yesterday. The National Security Agency, CISA, and the FBI—plus cyber agencies across eleven countries—put out a massive Joint Cybersecurity Advisory. The main plot twist? They’re all focused on a sprawling Chinese espionage operation using groups like Salt Typhoon, RedMike, UNC5807, OPERATOR PANDA, and GhostEmperor. They’re not being subtle; telecommunications, government networks, even infrastructure like transportation, hotels, and lodging have all taken direct hits. If you’re in utilities or critical infrastructure, especially water or energy—think Volt Typhoon and their ten-month-long joy ride inside a Massachusetts utility—they want your data and they want in for the long haul.

Salt Typhoon and crew are all about hijacking edge devices—those routers and gateways sitting right on your network’s doorstep. They exploit vulnerabilities like CVE-2024-21887 and CVE-2023-20198. According to the CISA advisory, once they’re in, they work overtime modifying routers for persistent access and pivoting into supposedly safe inner networks. Talk about commitment issues.

The scale of the challenge? According to Infosecurity Magazine, over half of all exploited vulnerabilities this year came from state-backed gangs—most of them Chinese—with a juicy focus on easy-to-hit edge infrastructure. Oh, and here’s a kicker: 69% of those vulnerabilities didn’t even need credentials. Meaning, “hi, I’m the Internet” was enough to stroll right in and hijack your systems.

It’s not just the tech. There’s an economic subplot brewing. Security Magazine highlighted that these attacks aren’t purely technical mischief—they’re supporting larger geostrategic goals, including tracking movements, intercepting communications, and, yes, espionage at scale. FBI cyber chief Jason Bilnoski said China’s big weakness is its reliance on domestic hacking firms—like Sichuan Juxinhe Network Technology and Beijing Huanyu Tianqiong—which have made enough mistakes that US investigators are catching up. That’s a rare silver lining.

Glitches in big tech are not helping. Microsoft faced major scrutiny after possible leaks related to its bug disclosure program involving Chinese engineers—especially on products like SharePoint that have already been used in attacks. As Lawfare points out, America’s overtrust in offshore personnel is now biting back, with defense cloud systems potentially exposed.

So what should listeners actually do? First, actually read the Joint Cybersecurity Advisory if you manage mission-critical networks or infrastructure—yes, you, I’m talking to that overworked sysadmin nuking old printer drivers at 3 AM. The advisory is packed with technical indicators of compromise, advanced threat hunting guidance, and prioritized patch lists. Patch those edge devices now; don’t let legacy routers be your downfall. Segment networks aggressively, set up continuous monitoring, and log everything. Enable multifactor authentication, and—please—don’t ignore those out-of-cycle security bulletins.

For small and medium businesses, industry expert advice is clear: information sharing works. The pending sunset of the Cybersecurity Information Sharing Act could be a disaster, so support reauthorization efforts and plug into trusted threat-sharing programs.
