China's Hack-a-thon: Ivanti's Java Jive, Google Sheets' Covert Comms, and PyPI's Pen Test Pandemonium!

This is your China Hack Report: Daily US Tech Defense podcast.This is Ting, your cyber-savvy, slightly caffeinated guide to the wild world of China-linked hacking shenanigans. Today’s China Hack Report comes in blazing, because the last 24 hours have given us a front-row seat to a China-nexus cyber offensive that is part Mission Impossible, part If Java Had Feelings.First up, the show-stealer today has to be the explosive CISA analysis on the Ivanti Endpoint Manager Mobile—EPMM for those in the know. We're talking about two freshly disclosed vulnerabilities—CVE-2025-4427, an authentication bypass, and CVE-2025-4428, which lets hackers execute pretty much whatever code their hearts desire. Now, picture patient zero: some unlucky org gets hit almost immediately after word gets out about a proof-of-concept exploit. Enter a China-linked threat group, according to the smart folks over at EclecticIQ, leveraging their suspiciously deep understanding of Ivanti’s guts. They were in, out, and siphoning off whatever savory LDAP credentials and network details they could get, fast as you please.Let’s take a closer look at the evil payload. We’re dealing with not one but two bespoke malware kits, each dropped onto the victim’s on-premise Ivanti systems. Both sets have their own loaders, all disguised as web-install.jar (because why get creative?). Set one comes with a little Java trickster called ReflectUtil.class and a sneaky listener called SecurityHandlerWanListener.class, which is used to siphon data and keep the door open. Set two swaps in the WebAndroidAppInstaller.class, but the game’s the same—code execution, persistence, and data exfil galore. The drop-off? Delivered via segmented Base64 chunks through special HTTP GET requests. You have to almost admire the craftsmanship, but no—they’re definitely on the naughty list.CISA’s biggest headline is the call for immediate action. If you run Ivanti EPMM, patch NOW—yes, like, open another tab and patch—and treat your mobile device management tools as high-value assets. We're talking about tightening access, continuous logging, and immediate network segmentation if you discover these indicator files. CISA’s also dropped some killer YARA and SIGMA rules if you're in need of detection ammo.A bit of whiplash? The threat landscape is accelerating. TA415, a China-aligned adversary, is now abusing Google Sheets and Calendar for covert command-and-control—think exfil and instructions hidden in your manager’s next meeting invite. They’re targeting U.S. government, think tanks, and the academic sector, so be especially wary if your inbox includes both state secrets and Google Calendar reminders about the office bagel inventory.One more curveball: last night, an AI-driven pen test tool dubbed Villager—think ChatGPT for hackers—clocked 11,000 downloads from PyPI, with Cyberspike, a suspected China-based crew, behind the curtain. CISA’s warning is clear: red-team frameworks are great for defenders, but today’s pen test tool is tomorrow’s attack kit, so scrutinize your network for unusual outbound connections, introduce stricter egress rules, and get those threat hunts rolling ASAP.Thanks for tuning in, listeners.
