This is your Cyber Sentinel: Beijing Watch podcast.

This is Ting, and you’ve tuned in to Cyber Sentinel: Beijing Watch. The cyber skies were especially stormy this week, so let’s jump right into the latest—and yes, listeners, there’s a lot to break down.

First, if you thought Beijing was taking a cyber summer vacation, forget it. CrowdStrike says Chinese state-linked cyberattacks on the US doubled in the last year, pushing past 330 incidents and continuing to rise. The folks over at SentinelOne are calling it China’s “golden age of hacking,” and there’s broad agreement in DC and in Silicon Valley. China’s not only hitting more targets, it’s getting much better at hiding inside networks once it’s in. We’re seeing campaign structures shift: instead of just government agencies like the Ministry of State Security, Beijing now licenses private contractors to hack away, outsourcing their cyberoffense at industrial scale. That means more attacks, more creativity, and honestly, more headaches for defenders.

Now, these attackers are lasering in on *strategic industries*, especially telecommunications and, gold-standard of all, semiconductors. In the last few months, Salt Typhoon (sometimes called RedMike, and yes, hackers love their code names) ramped up attacks on global telecom providers. Their signature move? Exploiting unpatched Cisco devices, slipping in through known CVEs like CVE-2023-20198 to install persistent shells and GRE tunnels. This gives them not just a foothold, but long-term, almost invisible access. Targets included US firms, big names like Comcast, and global carriers from South Africa to Korea. The broader goal? Tap lines, harvest strategic intelligence, and lie low for political leverage.

Taiwan’s semiconductor sector is still at ground zero for Beijing’s ambitions. Proofpoint and Reuters both report at least three new, previously unknown China-backed groups—UNK_FistBump, UNK_DropPitch, and UNK_SparkyCarp—using ultra-targeted spear-phishing, custom malware, and even building trust with insiders before launching remote access trojans. Taiwanese giants like TSMC declined to comment, but Proofpoint estimates at least 15 major firms, AND US financial analysts tracking the chip sector, were targeted.

Attack patterns run from surgical—single, well-crafted phish—to massive shotgun blasts of up to 80 malware-laced emails. The campaign’s all about stealth: compromised university accounts, fake job offers, customized malware with codenames like Voldemort. Their motive? Espionage supporting Beijing’s semiconductor self-sufficiency push and helping dodge US export restrictions. National Guard networks weren’t spared either—Salt Typhoon spent nine months undetected in one state’s Army National Guard, pulling sensitive data that could be used for military targeting later.

The tactical implication: Chinese cyber teams are leveraging supply-chain risk by infiltrating security vendors and telecom infrastructure. By hiding in routers and edge devices, they sidestep traditional perimeter-based defenses and, crucially, evade NSA detection due to domestic network traffic. That means CISOs need to step up segmentation, persistently patch, and monitor network edge devices—especially anything remotely connected to Cisco’s IOS XE platform.

Strategically, it’s clear that China views cyberspace as its main stage for creative risk-taking with the US. With major staffing cuts at CISA and the White House busy on other fronts, now’s the time to double down. All American companies in telecom, defense, and especially semiconductors should adopt proactive threat hunting, red team across supply-chain links, and lock admin privileges.

On the global stage, international response is growing: January’s US Treasury sanctions on Sichuan Juxinhe Network Technology are proof. But sanctions alone can’t outpace Beijing’s decentralized cyber machine. The pressure is on for tighter global info sharing and private-sector collaboration.

Hey listeners, Ting here with your Cyber Sentinel: Beijing Watch, and if you thought last week’s fireworks were over, think again. Let’s dive right into what’s been lighting up the U.S. cyber radar—spoiler alert: Salt Typhoon is not your average summer storm.

Salt Typhoon, one of Beijing’s recurring heavyweights, just finished a nine-month joyride through a U.S. state’s Army National Guard network. I know, “only state level,” right? But here’s the punchline: this gave them a backstage pass to sensitive comms between Guard units across all 50 states plus four U.S. territories. Imagine the access—admin credentials, network diagrams, even personally identifiable info for state cybersecurity folks. As the Department of Defense revealed, the haul included network configs and cross-state data streams. That’s not just insider info; that’s a skeleton key for targeting other state-level cyber defenses if future conflict heats up. When Guard units in 14 states are integrated with fusion centers tied into critical infrastructure, that breach isn’t just a line on a chart—it’s a full-blown escalation.

Tactically, Salt Typhoon stuck to the classics: exploiting old vulnerabilities in Cisco and Palo Alto edge devices. Listen up: we’re talking CVEs from as far back as 2018. They rented IPs to mask their tracks, swiped over 1,400 config files from more than 70 U.S. government and infrastructure outfits—energy, water, transport, you name it. The strategy is classic Beijing—collect, map defenses, pre-position for disruption down the road. The personal data lift gives them a playbook for future targeting, even retaliation campaigns against frontline cyber defenders themselves.

Strategically, we saw fallout echoing across telecoms and critical infrastructure. The DHS memo and experts agree: at this point, U.S. forces—state level or not—are working under the assumption their networks are compromised or degraded. It’s like playing chess where every move is already on WeChat in Beijing. And Salt Typhoon didn’t stop at Guard networks; over the past 18 months, they targeted leading telecoms (think AT&T and Verizon), wiretap systems, and government agencies, with recent attempts extending to Canada’s own providers. Meanwhile, the FBI and Canadian Centre for Cyber Security dropped joint warnings after Chinese actors siphoned call records and private comms.

Internationally, the pressure’s ratcheting up. Congress is pushing the Chip Security Act, which would force U.S. chipmakers to add geolocation “kill switch” tech. Problem? Those same switches could become new attack surfaces—giving Beijing or literally anyone with the keys the power to brick chips around the globe. Allies relying on U.S. tech aren’t loving it; it’s a digital game of hot potato.

Security pros—your action items this week: Patch those legacy edge devices immediately, especially if you’re running unsegmented Cisco or Palo Alto gear. Strengthen least privilege access, lock down SMB/CIFS, and encrypt traffic between states and critical infrastructure. The threat is persistent, stealthy, and working off an enormous trove of valid American credentials and diagrams. Assume compromise, double-check segmentation, and get your detection rules ready for weird edge-device chatter.

This is your Cyber Sentinel: Beijing Watch podcast.

Hey listeners, Ting here with your Monday circuit-surge of Cyber Sentinel: Beijing Watch. Let’s dive right into what’s been lighting up the cyber wires between China and the U.S. since last week.

Chinese cyber operatives have been working overtime, with fresh attack methodologies popping up like dubious pop-ups on a sketchy hotel WiFi. According to the Irregular Warfare Center, Chinese-backed crews, especially the infamous Volt Typhoon and the newly spotlighted Salt Typhoon, have been embedding sophisticated malware directly into our critical infrastructure—think power grids, water treatment facilities, and the networks that keep planes from crashing into each other. They don't just steal data; they pre-position code for potential sabotage. This is SCADA targeting 2.0, and the FBI warns it’s well beyond anything the West has dealt with before. The goal? To create a digital powder keg Beijing can set off if tensions ever snap over Taiwan or elsewhere.

The range of industries under siege is eye-watering: agriculture, biotech, aviation, energy, and academic R&D. The FBI has over 2,000 open PRC-related investigations right now, which tells you all you need to know about the scale. It’s not just broad; it’s deep. We’re seeing economic espionage that lets Chinese firms leapfrog costly R&D, undermining U.S. market positions and, ultimately, our ability to out-innovate in strategic sectors. Case in point: Yanjun Xu, the first Chinese intelligence official extradited and convicted in the U.S. for lifting aviation secrets, providing a rare, unvarnished look at how the Ministry of State Security organizes these efforts.

Tactically, China is mixing up its toolset. DDoS attacks tied to the “Great Cannon,” supply chain malware, and even AI-fueled tricks like deepfake campaigns have been reported. Just this week, the State Department scrambled after an AI-generated voice deepfake impersonated Secretary Marco Rubio, nearly triggering a diplomatic incident. According to the New York Times, these deepfakes are getting so realistic, U.S. officials are pushing for urgent content authentication protocols.

Internationally, pressure is mounting. The U.S. Senate is not just grilling Defense nominees but also warning corporate leaders—like Nvidia’s Jensen Huang—against dealings that could educate or equip Chinese military-linked chip buyers. Meanwhile, the DOJ’s new Data Security Program is now fully in force, prohibiting sensitive data transactions involving China and five other “countries of concern.” And in the Pacific, countries like Palau and the Marshall Islands are shoring up cyber and physical defense against hybrid Chinese pressure, sometimes with U.S. and Taiwanese help—though, as Asia Times highlights, digital resilience remains a work in progress.

So, what can you do beyond crossing your fingers and updating your antivirus? At the tactical level, double down on zero-trust architecture, segment your networks, and assume that anything with a login is a target. Strategically, public-private threat intelligence sharing is more important than ever and regular cyber resilience drills for critical operations are a must. And maybe…just maybe…think twice before clicking on that email from “Rubio at State dot gov.”

This is your Cyber Sentinel: Beijing Watch podcast.

Welcome back listeners, this is Ting, your cyber sage with a side of sass, reporting on Cyber Sentinel: Beijing Watch, and frankly, you’d need a quantum computer just to keep pace with the cyber drama out of China this week. Let’s jump right into the mayhem.

First up, criminal intrigue at 35,000 feet: Zewei Xu, the alleged Chinese cyber-espionage mastermind from Silk Typhoon—also known as Hafnium—was nabbed in Milan while changing planes, thanks to a U.S.-Italy sting. Xu is accused of spearheading attacks on the University of Texas’s COVID-19 research and running mass phishing campaigns that compromised thousands of American email accounts. He wasn’t just after health data—according to Italian authorities and the FBI, his haul included confidential U.S. government policy briefs and high-value intellectual property. If extradited, Xu could face decades in an American prison, and his arrest sent an unmistakable message to state-backed hackers everywhere: the net is tightening.

Meanwhile, back in Beijing, the Chinese Ministry of Foreign Affairs is publicly fuming, demanding that Italy guarantee Xu’s rights and blasting what they call “political repression under the guise of cyber law.” The diplomatic fallout is just getting warmed up.

On the tactical front, attack methodologies keep mutating. Chinese operators are increasingly targeting soft underbellies—think boutique law firms in D.C., where last week, suspected Chinese hackers breached top legal advisories for insider intel. The focus is no longer just government agencies and defense contractors; soft targets like financial consultancies and smaller manufacturers are firmly in Beijing’s crosshairs.

Let’s talk tech. China’s access to Electronic Design Automation, or EDA, software is back on. U.S. restrictions have eased, letting giants like Cadence and Synopsys deal freely with Chinese chipmakers. Experts from Forrester and the India Electronics & Semiconductor Association warn this could turbocharge Chinese R&D, but it also creates a wider playing field for IP theft campaigns—a gift to China’s cyber operators who specialize in siphoning chip design secrets.

Critical infrastructure is glowing red on every dashboard this week. Reports from security leaders at Dragos and Palo Alto Networks underscore a surge in attacks against OT—operational technology—particularly in energy and utilities. Chinese groups are using sophisticated, multi-stage exploits to pivot from IT networks to the operational core, sometimes leveraging the same techniques seen in the Colonial Pipeline attack. Legacy reporting structures and poor IT-OT integration remain major weaknesses; when a water plant or energy grid is hit, delays in reporting and fragmented crisis teams give adversaries way too much of a head start.

On the international stage, Washington, Brussels, and Canberra are all pushing for stricter cybersecurity standards and faster information sharing. The U.S. Secret Service’s own stumbles have fueled bipartisan support for better infrastructure security—meaning more funding and regulatory tailwinds are on the way.

So what’s my advice, both tactical and strategic? Patch fast, especially for Citrix Netscaler gateways, and pay attention to CPU vulnerabilities like Zenbleed found in AMD chips—these are being weaponized for lateral movement. Segment your networks, practice joint IT/OT incident response, and put real money into upskilling your staff. If you haven’t banned sketchy browser extensions organization-wide, you’re basically leaving the back door unlocked.

Strategically, this is a long game. China’s cyber initiatives are relentless, professional, and integrated with their broader geopolitical ambitions. Prepare for blended attacks that combine espionage, sabotage, and influence ops. As always, vigilance isn’t optional—it’s existential.

This is your Cyber Sentinel: Beijing Watch podcast.

Hey listeners, Ting here—your no-nonsense source for all things China, hacks, and cyber-power plays. Let’s jump right into the week’s headline: Beijing’s cyber operators have kicked things up a notch, and the impact on US security is grabbing everyone’s attention from Congress to container ports.

First up, Chinese-backed groups like Volt Typhoon are adopting so-called “living off the land” methodologies. That means instead of flashy malware, they’re blending in by exploiting everyday admin tools already present in systems. This week, Volt Typhoon and the lesser-known Salt Typhoon were specifically cited in Senate Armed Services Committee hearings. Their favorite targets? Utilities, defense contractors, and logistics hubs—think ports like Savannah and Houston, which have battled sophisticated AI-backed intrusions in just the past few days. CISA has ramped up seaport cyber drills as a direct response, urging more public-private cooperation since most port infrastructure is privately owned.

Meanwhile, Chinese-linked attacks aren’t just about disruption anymore—they’re about control and strategic leverage. The 2025 threat trend is moving fast from simple IP theft to the risk of holding infrastructure hostage. Evidence piles up from ports to power grids, as AI-generated phishing and malware campaigns surge. After all, Check Point Research reported a whopping 70% year-on-year rise in US utility attacks. Siemens and Ponemon Institute highlight that over 75% of energy and manufacturing firms faced incidents last year, but half admit their defenses are lacking—yikes.

On the regulatory front, FCC chair Jessica Rosenworcel is pushing reforms, and the Department of Justice just finalized rules that restrict how US entities can share sensitive data with China, Russia, and Iran. And yes, enforcement started July 8, so the clock is ticking for compliance. Over at the USDA, Secretary Tom Vilsack isn’t sleeping on the agri-sector either. The new National Farm Security Action Plan aims not just to block Chinese land deals near US bases but to harden the cyber backbone of America’s food supply. Why? Because so many farms now run on smart tech—GPS, IoT sensors, drone swarms—and one breach could cause nationwide shortages, as proven by the United Natural Foods hack last month.

Internationally, there’s a rising chorus for deterrence. The Senate wants the Pentagon to roll out full-spectrum military options to stop Beijing from attacking US critical infrastructure in a crisis. Deterrence has been tricky—historically, adversaries just don’t fear US retaliation in cyberspace the way they do with conventional force. But now, with China testing boundaries by burrowing into places like Guam’s networks, policymakers are under pressure to get serious about response strategies.

What can listeners do? For US critical industries: embrace robust segmentation, relentless red teaming, and supply chain vetting. Ports, utilities, and farms need to treat “who manages your tech” as a strategic question. At the tactical level, AI-enabled intrusion detection, least-privilege access, and investing in cyber workforce skills are all non-negotiable. Public-private threat sharing and rapid incident reporting can make or break resilience when seconds count. And if you’re in charge—never assume your legacy systems are too boring to target; China’s playbook is proof that every corner of the network matters.

This is your Cyber Sentinel: Beijing Watch podcast.

You’re tuned in to Cyber Sentinel: Beijing Watch, and I’m Ting, your lively, all-things-China-and-cyber whisperer. Let’s dive straight into this week’s digital crossfire, making waves from Beijing to the Beltway.

Right at the top of the headlines is the arrest of Xu Zewei in Milan—yes, Milan, where the pasta is hot and apparently so are the extraditable cyber operatives. Xu, a 33-year-old Chinese national, is now facing a nine-count indictment in Texas for hacking, wire fraud, and aggravated identity theft. His cyber fingerprints? All over the Silk Typhoon and Hafnium campaigns. Both are marquee operations favored by Beijing’s Ministry of State Security, especially the Shanghai State Security Bureau. Xu didn’t act alone—there’s a co-defendant, Zhang Yu, still at large and probably looking over his shoulder right now.

Let’s talk attack methodologies, because Silk Typhoon and its Hafnium alter ego are ground zero for China’s current tactics. Zero-days? Oh, they love them. Xu and his pals exploited vulnerabilities in Microsoft Exchange Server, specifically CVE-2021-26855, to break into over 60,000 U.S. entities, from universities to government agencies. Once inside, they deployed web shells for long-term access, going after intellectual property, critical infrastructure, and—most notably—COVID-19 research. Imagine hacking UT’s vaccine labs while the world desperately needs answers. It’s as aggressive as it is strategic.

But why is this week different? Xu’s arrest is a big exclamation mark in cyber diplomacy. The Justice Department, working with Italian law enforcement and the FBI, managed a rare public collar. It’s significant because, let’s be honest, most indicted APT actors never see a courtroom, let alone Milan’s airport. This arrest signals a hardening stance—Washington is pushing hard on international partners to tighten extradition processes for cyber suspects connected to state-affiliated campaigns. And China’s response? Predictable silence. But for Beijing, this exposes an uncomfortable truth: relying on contractors like Shanghai Powerock Network Co. Ltd. to launder state direction isn’t as opaque as they’d hoped.

Zoom out and you’ll see Silk Typhoon isn’t alone. Salt Typhoon, another PRC hacking crew, was recently discovered prying open telecom giants like Rogers Communications in Canada and potentially partners in the U.S. and global markets. These campaigns often target communications infrastructure, seeking not just raw data but strategic insight into government and contractor communications. The goal? Worldwide communications supremacy, according to those tracking their moves.

So, what’s the tactical and strategic takeaway for defenders? Tactically, patch zero-day vulnerabilities immediately—especially on Exchange Servers and Cisco gear. Monitor for web shell activity and enforce least privilege models in your organization. Strategically, treat third-party contractors with a higher level of skepticism—these proxies aren’t just a threat to immediate targets, but serve as force multipliers for intelligence collection across whole industries.

That’s the front line for this week. Subscribe for deep dives, digital dramas, and a touch of my techie sass every week. Thanks for tuning in—stay safe out there. This has been a quiet please production, for more check out quiet please dot ai.

This is your Cyber Sentinel: Beijing Watch podcast.

Listeners, it’s Ting, your favorite cyber sleuth, here on Cyber Sentinel: Beijing Watch, and the digital drama has been absolutely turbocharged this week. Let’s get right to the code!

In a plot twist worthy of a spy novel, Xu Zewei, an alleged contract hacker for China’s Ministry of State Security, was nabbed by Italian authorities in Milan after years on the most-wanted cyber list. Xu and his co-conspirator Zhang Yu—who, by the way, is still at large—were indicted for swiping critical COVID-19 research from U.S. universities back in those early pandemic months. The arrest, announced by the U.S. Justice Department, sends a bold message: no more safe havens for cyber mercenaries, regardless of which flag they wave.

But let’s talk methodology. Xu, working through Shanghai Powerock Network, targeted American immunologists and virologists by exploiting Microsoft Exchange Server vulnerabilities. This was part of the infamous HAFNIUM campaign—also called Silk Typhoon by some in the biz—which compromised over 60,000 U.S. entities. That’s not just hospitals and labs, folks; think small businesses, government agencies, and any organization too slow to patch. Once inside, Xu’s crew quietly exfiltrated sensitive mailbox data and address books, giving Beijing’s cyber intelligence machine a real-time feed on U.S. research and corporate secrets.

What’s new is how these actors, under direction from the Shanghai State Security Bureau, have refined their operational security. They leveraged zero-day exploits and living-off-the-land techniques to blend with legitimate network traffic. This week’s arrest confirms they’re also expanding into drone-based and social media-enabled reconnaissance, literally flying over targets to grab physical imagery or digitally manipulating content to sow confusion. In Taiwan, for instance, authorities scrambled after a Rednote post allegedly showed Chinese-controlled drone footage of an air base, only to discover it was a digital fake designed to undermine trust in Taiwan’s defenses.

Attribution, as always, is tricky. While Xu’s capture is a coup, analysts like John Hultquist from Google’s Threat Intelligence warn the impact may be short-lived. Beijing’s cyber apparatus isn’t just one guy in a hoodie; it’s dozens of rotating teams, each learning from every takedown. It’s fueled by state funding, companies like Powerock, and a culture that rewards digital espionage. Beijing officially condemned the arrest, saying it was “firmly opposed,” but let’s be real—the denials ring hollow when the evidence is all over seized servers.

The international response? The U.S. is doubling down with indictments, extraditions, and a hardening of its cyber defenses. But it’s not just about playing defense. Taiwan’s Defense Minister Wellington Koo emphasized increased military and cyber budgets, and civil society groups in the Pacific are spotlighting Beijing’s use of media manipulation to sway lawmakers—especially in places like the Solomon Islands.

Tactically, we’re seeing more attacks on critical research, more economic espionage, and a blending of cyber and information warfare. Strategically, the implication is clear: This is not just about stealing secrets; it’s about shifting global power balances, especially as the U.S. and its allies rethink their cyber and industrial policies.

Your next steps? Patch fast, monitor for living-off-the-land behaviors, and double-check the authenticity of any imagery or media files—especially those originating on Chinese-owned platforms. And if you spot Zhang Yu, maybe give the FBI a buzz.

This is your Cyber Sentinel: Beijing Watch podcast.

Welcome back to Cyber Sentinel: Beijing Watch! I’m Ting, your go-to guide for all things China, cyber, and a dash of digital drama. Let’s rip the Band-Aid off—if you thought last week’s headlines were wild, you haven’t seen anything yet.

The past few days have given us a masterclass in Beijing’s cyber maneuvering. First up, the U.S. Treasury Department found itself at the business end of a sophisticated cyber assault clearly linked to the Chinese Communist Party. The primary targets? The Office of Foreign Assets Control and the Treasury Secretary’s own circle. Why them? They’re the folks who hit Chinese companies with sanctions, especially those linked to supplying Russia’s war machine or orchestrating earlier cyber campaigns. This wasn’t just a smash-and-grab—think reconnaissance and access laying, almost certainly prepping for bigger moves if push comes to shove over Taiwan or supply chain disruption.

Meanwhile, at the policy level, Representative Moolenaar and the House Homeland Security Committee rolled out the Strengthening Cyber Resilience Against State-Sponsored Threats Act. They’re not mincing words. According to Moolenaar, the likes of Volt Typhoon and Salt Typhoon have already compromised multiple U.S. systems, and the time for hand-wringing is over. The bill basically mandates sweeping risk assessments of Chinese cyber threats, handing federal agencies more funding, more authority, and a clear directive: stop Chinese infiltration before it threatens markets or—worse—military logistics.

On the hacking front, SentinelOne, a global security heavyweight, narrowly sidestepped a breach by threat actors linked to China’s PurpleHaze crew. Their subsequent investigation, however, uncovered much broader carnage. These attackers aren’t picky—everyone from government, to energy, to food and agriculture is in their crosshairs. Most chilling? It’s not just the U.S. They’ve hit more than 70 organizations worldwide in under a year.

We’ve got attribution evidence stacking up, too. The U.S. Treasury, in tandem with the U.K., has sanctioned Wuhan XRZ, a Ministry of State Security (MSS) front, plus notorious individuals Zhao Guangzong and Ni Gaobin. These aren’t shadowy figures anymore—they’re named, shamed, and cut off from Western finance.

So what do you do? First, get granular with endpoint monitoring—these attacks almost always start with phishing and escalate using sophisticated malware like ShadowPad. Isolate critical infrastructure with network segmentation. Invest, like yesterday, in threat intelligence partnerships—no more siloed defenses. And, strategically, stay vocal in international forums. Only a coalition approach—U.S., EU, and allies—can box in Beijing’s cyber operatives.

The big picture? Chinese cyber campaigns are about more than stealing blueprints; they’re setting the stage to undermine responses in a crisis, especially over Taiwan. The tactical fixes buy us time, but strategically, we’re playing a long game. Make no mistake: In cyber, as in chess, Beijing is thinking at least three moves ahead.

That’s your download from the cyber trenches. Ting, signing out—until the next breach breaks. Stay sharp.

Evening, cyber sleuths—Ting here, bringing you another brisk but bristling update from Cyber Sentinel: Beijing Watch! Let’s toss the intros aside and get right into this week’s charged game of digital cat and mouse between the US and China.

If you thought July would offer a midsummer lull, think again. Over the past few days, Chinese cyber operations have redoubled their focus on *critical U.S. infrastructure*—and not with your garden-variety phishing. We’re talking about advanced persistent threat groups like PurpleHaze (hello, APT15 and UNC5174) leveraging *multi-stage reconnaissance* and *malware implants* to quietly burrow into networks across manufacturing, finance, logistics, and yes, even cybersecurity firms like SentinelOne. That’s right: the watchdogs themselves have been watched, poked, and prodded, as public disclosures show that “internet-exposed servers” became ground zero for these probes as recently as March. PurpleHaze and allied clusters tracked over 70 entities in the past nine months alone, spanning not only private industry but also government, telecoms, and research facilities.

Out in the wild, the tech behind these attacks is evolving. Besides the usual credential theft and lateral movement, analysts have flagged *rogue communication modules* hidden in Chinese-manufactured solar inverters—a nightmare for grid operators. These covert channels could let attackers bypass firewalls and command infrastructure from afar. Mike Rogers—yep, the former NSA chief—has even warned publicly that Beijing’s strategy seems to involve keeping the West’s core systems perpetually at risk, using everyday tech as a digital Trojan Horse.

Attribution has sharpened as well. The finger points unambiguously at Chinese state-directed actors, especially the CCP’s cyber apparatus. The U.S. Treasury breach in December—targeting the Office of Foreign Assets Control after it hit back with sanctions—was a political and intelligence-gathering move. Beyond espionage, such operations are aimed at disrupting military supply chains and, should tensions escalate over Taiwan, blunt America’s rapid response capability. Taiwan itself, meanwhile, is fending off a nearly unfathomable 2.4 million cyberattacks per day.

International response? Washington’s political gears are in motion. The House Homeland Security Committee just grilled experts about Beijing’s tactics, while lawmakers like Chairman Moolenaar are pushing the Strengthening Cyber Resilience Act to harden defenses and hold Chinese actors accountable. There’s particular concern about Volt Typhoon and Salt Typhoon, persistent groups already embedded deep in U.S. systems.

Tactically, defenders need to double down on network segmentation, ironclad supply chain vetting, and continuous threat hunting—especially on internet-facing assets. Strategically, the U.S. must build resilience not just with regulations but also public-private partnership, and, frankly, a little good old-fashioned paranoia. Supply chain security audits, zero-trust architectures, and threat intelligence sharing are not optional—they’re survival mechanisms.

That’s a wrap for now—keep your ports closed, your firmware patched, and your humor sharp. This is Ting, signing off until the next byte.

Hey cyber sleuths, Ting here for your weekly download on all things China and cyber. Let’s zip straight into the thick of it—because if you haven’t noticed, Beijing’s cyberspace playbook is evolving faster than my VPN can keep up. This week, the U.S. faced another round from China’s heavy hitters, Salt Typhoon and Volt Typhoon, and the tactics are anything but old school.

Let’s start with the big breach: Salt Typhoon reportedly wormed its way into the backbone of US broadband—think Verizon, AT&T, Lumen Technologies. This wasn’t just about swiping your grandma’s Netflix password. These hackers may have accessed sensitive networks used for federal court-authorized wiretaps, which could potentially expose how U.S. law enforcement monitors communications. And for months, Salt Typhoon’s operatives moved through infrastructure handling huge swaths of internet traffic, fishing for intel while barely leaving a ripple. Chinese officials, of course, claim ignorance and accuse Washington of “framing” them, but nobody’s buying those fortune cookies lately.

Zooming out, strategic intent is crystal clear. The Chinese Communist Party is not just poking at economic interests—they’re directly undermining critical infrastructure. Recent operations have targeted the Treasury’s Office of Foreign Assets Control and even the Secretary’s office itself, clearly retaliation for sanctions on Chinese companies. These aren’t just isolated attacks; they’re part of a coordinated effort to surveil, disrupt military supply lines, and weaken U.S. readiness for any Pacific dust-up—especially as Taiwan remains a flashpoint.

What’s new on the technical front? Attackers are stacking zero-day exploits alongside living-off-the-land techniques, allowing them to quietly dwell undetected—take Volt Typhoon’s 300-day staycation inside the US electric grid last year. This isn’t brute-force or smash-and-grab hacking—it’s stealth, persistence, and an appetite for long-term access across communications, utilities, manufacturing, even maritime and transportation sectors.

How’s Washington responding? The legislative gears are grinding faster. House Republicans dusted off and reintroduced the Strengthening Cyber Resilience Against State-Sponsored Threats Act, aiming to amp up resources and authority for the feds to outpace Beijing’s cyber game. Security agencies are doubling down on threat modeling, segmenting networks, enforcing strict patch cycles, and mandating cyber hygiene at every level.

What should defenders do now, tactically and strategically? In the short term: hunt for anomalous traffic, audit privileged access, and beef up endpoint detection. Strategically, critical infrastructure operators must assume persistent compromise and plan for resilient operations. Every org needs a rapid incident response plan, regular red teaming, and close coordination with CISA and sector-specific ISACs.

Bottom line—this week’s barrage hammers home that cyber defense isn't a technical problem alone; it's a national security imperative. Stay curious, stay cautious, and—seriously—patch everything. This is Ting, signing off until the next byte.
