This is your Red Alert: China's Daily Cyber Moves podcast.

Name’s Ting. If you’re hearing this, it means you’re on high cyber alert—and you’d better stay caffeinated, because the past 72 hours in cyberland have been pure adrenaline. Let’s cut the fluff and jump right into the digital trenches.

July 3, 2025, kicked off with a blaring advisory from CISA and the FBI after China-linked groups—Salt Typhoon and PurpleHaze—upped their game targeting US networks. Salt Typhoon, hot off exploiting Cisco IOS XE software vulnerabilities (CVE-2023-20198, CVSS score: a perfect 10 out of 10, nothing less for these folks), started with Canadian telcos but quickly set their sights on US systems. Their method? Slip in, snatch configuration files, then set up GRE tunnels: that’s cyber jargon for building secret passageways to siphon data out undetected. Can you say “cyber-espionage deluxe”? These tunnels aren’t just for eavesdropping—they’re persistent, designed for long-haul operations and even leverage compromised networks to expand their footprint further into US targets.

Flash forward: July 4, while you’re lighting fireworks, these actors are mapping the who’s who of US critical infrastructure. Industry sources confirm that over 70 organizations across manufacturing, finance, research, and particularly telecommunications have seen reconnaissance and low-key breaches since at least July of last year. Take SentinelOne: this cybersecurity giant found itself in Salt Typhoon’s crosshairs, along with their IT logistics partner. The attackers’ strategy is classic: map exposed servers, plan their next moves, and slip quietly back into the shadows, prepping for future ops.

By late afternoon today, July 5, emergency alerts from CISA and FBI have started pinging inboxes nationwide. Key targets now include Comcast—the titan of US mass media—and Digital Realty, a cornerstone of America’s data center infrastructure. These are not random strikes; attackers are burrowing into providers that underpin everything from banking to healthcare. The goal? Monitor the deepest layers of internet traffic, and if escalation comes, disrupt or control the digital arteries of the United States.

Timeline, rapid-fire:
- July 3: CISA/FBI joint advisory on new GRE tunneling by Salt Typhoon.
- July 4: Reconnaissance spikes on SentinelOne, IT logistics firms, and US telcos.
- July 5: Emergency alerts warn that Comcast and Digital Realty may be compromised; potential for attackers to deepen control over national data flows.

Required defensive actions? If you’re running Cisco IOS XE, patch that vulnerability yesterday. Monitor for unexpected GRE tunnels—if you see one and you didn’t order it, you’ve got company. Lock down exposed servers and double-check your data center connections. Expect attackers to escalate: they’ll shift quickly from espionage to active disruption if provoked.

So, what’s next? If these actors get comfortable, don’t be surprised if they leverage this access for kinetic impact—think data destruction or mass outages. Stay sharp, keep logs tight, and make sure your incident response team has a direct line to CISA.
