Cyber Ninjas Unleashed: Inside the US-China Hacker Showdown

This is your Dragon's Code: America Under Cyber Siege podcast.

I'm Ting and the dragons are circling, folks! Welcome to Dragon’s Code: America Under Cyber Siege. You want the inside scoop on this week’s wild cyber cat-and-mouse between the US and China? Strap in.

Over the past few days, the US cyber landscape has been a live-action thriller. Most of the excitement centered around a wave of attacks exploiting *not one, not two, but three brand-new Cisco zero-day vulnerabilities*. The threat actors? All reputable sources are pointing at sophisticated China-linked collectives, notably the group Cisco dubs ArcaneDoor. For those of you tracking names, Microsoft tracks these actors as Storm-2077, and Google Threat Intelligence calls one campaign Brickstorm.

It went down like this: Chinese-aligned hackers zeroed in on perimeter appliances—think the Cisco firewalls guarding hundreds of federal agency networks. The attack methodology? Pure cyber ninja stuff. First, they slipped in using the zero-days, then escalated privileges and planted Go-based backdoors. These backdoors were especially devious, persisting through system reboots and upgrades. Once inside, the hackers could override security protections, move laterally, collect data, or even deploy additional malware. BitSight’s analysis highlighted that this kind of persistence means even a patched device can remain compromised if not thoroughly scrubbed.

The impact? CISA chief Chris Butera said the directive was “emergency mode”—the threat was so severe that agencies had just 48 hours to hunt down evidence of compromise on every Cisco ASA device. CISA ordered step-by-step forensics, including dump reviews and hunting for specific indicators of compromise. No agency was named, but you can bet your bottom bitcoin the whole federal stack was sweating. Internationally, the UK’s National Cyber Security Centre also set off their alarms, seeing implant code and command execution targeting critical infrastructure systems.

Cybersecurity titan Sam Rubin from Palo Alto Networks noted the attackers had matured their tactics, pivoting from global espionage to a US-specific focus—defense contractors were on the menu. Google’s Threat Intelligence Group highlighted the scale: the campaign ran for nearly 400 days, showing crazy patience and resource allocation.

Attribution-wise, Cisco Talos, Google, and the US government agree it’s overwhelmingly likely these campaigns source back to Chinese state-aligned groups. They point to shared toolkits—like PlugX and RainyDay malware—same RC4 keys, and similar loader techniques. The attackers even leveraged legitimate Windows applications for sideloadings, such as DLL injection, making detection that much harder.

What did we learn? Experts across the board stress, patch fast and patch everything. But that’s not enough. You need in-depth forensics, continuous monitoring, and, as the Navy’s cyber chief pointed out, an all-hands culture. And as Michael Hiatt from Epirus warned at the Air, Space & Cyber Conference, don’t get caught flat-footed: the adversary’s drone and cyber arsenals are massive, and the US must innovate and outmaneuver, not just outnumber.

So, listeners, if you think the cyber headlines were wild last week, buckle up—there’s no sign the siege is letting up soon.
