China's Cyber Smackdown: Phantom Taurus Gets Saucy, Cisco Catches Heat, and Uncle Sam Sweats

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

Listeners, it’s Ting, your cyber oracle with a dash of sass and a terabyte of news. Let’s skip the pleasantries because today’s Red Alert is as urgent as caffeine on a Monday morning: China’s cyber operations have sprinted from stealth to sledgehammer in the span of 48 hours, and the US digital front lines are crackling louder than my firewall’s fan.

Let’s kick off with the beef: as of late last night, the Cybersecurity and Infrastructure Security Agency, or CISA, rang the digital alarm bells on a pair of Cisco ASA and Firepower Threat Defense vulnerabilities being exploited at scale. According to CISA’s Emergency Directive 25-03, Chinese state hackers have hopped onto two fresh exploits—CVE-2025-20333, a critical buffer overflow, and 20362, a pesky missing authorization flaw. Picture this: nearly 50,000 Cisco firewalls sitting online, half asleep, and 19,610 of those are US-based. Cisco’s own threat advisory says patches are out and workarounds are effectively imaginary, so agencies—if you can hear me, patch like your network’s life depends on it, because frankly, it does.

But here comes the drama. Reports confirm Shadowserver lit up the socials with evidence of daily scanning for these unpatched appliances, a red flag that Salt Typhoon—China’s infamous cyber outfit—might not be lurking but actively prowling. Salt Typhoon has a track record from last November’s election shenanigans, right up through a Treasury Department intrusion just months ago. They love a good US telecom breach; Viasat and some nine other companies found that out the hard way.

As if that weren’t enough, enter Phantom Taurus, the new heavyweight division of Chinese espionage. Palo Alto Networks’ latest report dropped just 24 hours ago and it’s a doozy: Phantom Taurus has moved from hitting embassies and foreign ministries abroad to leveraging their custom NET-STAR malware against U.S. government and telecom systems. Think fileless IIS backdoors, memory-resident payloads, and so much AMSI evasion code that it makes Windows security teams want to cry into their Red Bull.

Timeline-wise, it’s been relentless: Sunday saw the mass Cisco scans, Tuesday came the first confirmed exploitations, and by this morning, CISA and FBI teams are working through the night issuing emergency bulletins, coordinating takedowns, and bolstering logging and detection at the nation’s biggest agency perimeters. Threat researchers warn the pattern matches previous election-cycle intrusions, with the added spice that Phantom Taurus’ tools now automate lateral movement and data exfiltration of diplomatic comms at a scale we’ve only theorized about.

What’s next? If agencies miss the narrow patch window, escalation scenarios start to look ugly: mass data theft, shut-downs of telecom and transport, even manipulation of official communications. The US government and the private sector need to: patch immediately, segment traffic, limit external access to admin panels, and triple check logs for the NET-STAR and Specter malware signatures.

Listeners, that’s it for today’s frontline dispatch. China’s cyber moves are getting bolder, slipperier, and, dare I say, strangely elegant—a classic mix of brute force and stealth. So double-check your updates, watch those logs, and don’t let Phantom Taurus ghost your network. Thanks for tuning in to Red Alert. Don’t forget to subscribe, and stay witty, stay vigilant.
