Volt Typhoon Ninjas Pwn VMware: CISOs Panic as Chinese APTs Go Ham on US Infrastructure

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

Today on Digital Frontline: Daily China Cyber Intel, it’s Ting buzzing in, and trust me, caffeine isn’t enough to keep up with the pace of things when Chinese advanced persistent threat actors are moving faster than a mid-level manager on project deadline day. So, let’s jump right in—no fluff, just cyberstuff.

First, the splashiest headline in the last 24 hours: Microsoft’s SharePoint Server is once more at the center of the cyber hurricane, thanks to brand-new vulnerabilities—CVE-2025-49704, 49706, and 53771—being exploited at scale. This isn’t your usual script kiddo attack, either. Security teams at Check Point and Microsoft confirm that Chinese-backed actors are leveraging these flaws for privilege escalation and authentication bypass, targeting US government agencies and sensitive sectors like energy, telecoms, and, yes, water. That means both your hospital’s data and the city’s hydration could be on the table.

Now, let’s talk tactics. Volt Typhoon, operating with a level of stealth best described as “ninja but with a PhD,” continues its living-off-the-land approach. These crews don’t drop malware bombs, they blend in—using built-in tools to snoop around undetected, sometimes for months. Ciaran Martin, ex-chief over at UK's National Cyber Security Centre, pegged it as “everything, everywhere, all at once.” It’s not just espionage anymore but active shaping of future disruptions, from power grids to transportation[Telegraph]. According to Google’s Threat Intelligence Group, this isn’t theory; these guys have started jumping straight past endpoint security tools, hitting VMware vSphere and ESXi hosts right at the virtualization layer. They’re compromising hypervisors, rebooting them into single-user mode, and deploying legit tools like Teleport for persistent, under-the-radar access. Then they’re off to the races: pivoting into backups, exfiltrating data, and delivering ransomware payloads. Retail, airlines, insurance—no US sector is off limits.

What do defenders do when the perimeter is basically Swiss cheese? Experts urge architectural defenses: proactive configuration, strict network segmentation, disabling ESXi shell access, and isolating backups entirely. Google’s team practically begged organizations to ditch single-factor logins—if your IT desk still resets passwords on faith after a “lost badge” call, it’s game over. Switch to phishing-resistant multi-factor authentication yesterday.

CISOs, take note: detection and hunting must pivot away from endpoint to infrastructure. SIEMs and NDRs should be tuned to spot lateral movement, privilege escalation, and shell-level activity on virtualization stacks.

For businesses: Assume breach, monitor identity and infrastructure ruthlessly, and run DR tabletop exercises regularly. If your backups aren’t air-gapped, your recovery plan is fiction. At least you’ll have a good cyberwar story to tell.
