This is your China Hack Report: Daily US Tech Defense podcast.
Hey tech guardians! Ting here with your China Hack Report for June 3rd, 2025. Grab your coffee and let's dive into the digital battlefield where things have been absolutely wild in the last 24 hours.
So yesterday, Defense Secretary Pete Hegseth practically set the Shangri-La Dialogue on fire with his blistering assessment of China's cyber operations. He didn't mince words, folks – he explicitly called out Beijing for preparing what he termed "hybrid warfare" against American infrastructure. This comes just two days after Senate Democrats formally urged Homeland Security to revive the Cyber Safety Review Board to investigate that massive China-linked telecommunications hack that's been making headlines.
The Treasury Department is still dealing with aftershocks from that December breach where Chinese state actors targeted the Office of Foreign Assets Control. CISA just issued an emergency directive last night requiring federal agencies to implement their new patch for the "Salt Serpent" vulnerability within 48 hours – not days, HOURS people! This exploit bears striking similarities to the Salt campaign identified earlier by the House Committee on Homeland Security.
Banking and energy sectors are taking the brunt of it today. Three major financial institutions reported unusual network activity matching the Flax Typhoon signature, while two Midwest power distribution companies detected intrusion attempts that CISA attributes to the same actors behind the "Volt" campaign mentioned in congressional testimony.
The most concerning development? A new strain of malware dubbed "Jade Viper" discovered by Mandiant researchers late yesterday. This nasty piece of work specifically targets industrial control systems and has already been detected in water treatment facilities in Nevada and Arizona. CISA's immediate recommendation is to air-gap critical operational technology networks and implement their newly released detection rules.
For immediate defensive actions, CISA Director Jen Easterly released an advisory at 0600 this morning recommending:
- Immediate password rotation for all admin accounts
- Disabling of all Chinese-manufactured IoT devices in sensitive networks
- Implementation of the "Shield-25" detection ruleset
- Blocking all traffic to the newly identified command and control servers in the APAC region
Look, I don't want to sound alarmist, but this coordinated activity suggests Beijing is positioning for something bigger. The targeting of water systems alongside financial institutions follows the exact playbook outlined in that January Soufan Center intelligence brief on China's critical infrastructure infiltration strategy.
Stay vigilant, patch fast, and keep your detection tools updated. This is Ting, signing off until tomorrow's China Hack Report. Remember: in cyberspace, paranoia is just good planning!
