If you’re a TikTok user who has ever worried, even a tiny bit, that the People’s Republic of China might have an interest in your behavior, preferences, movements, or social graph, take heart. A newly released Joint Cybersecurity Advisory from intelligence agencies in the United States, Canada, the U.K., Australia, New Zealand, and a long list of allied intelligence agencies proves beyond any shadow of a doubt that the PRC is far too busy compromising the world’s telecommunications infrastructure to care about your TikTok “For You Page.”

Nothing to see here. Scroll on.

For those who like their reassurance with a side of evidence, the advisory—titled “Countering Chinese State Actors’ Compromise of Networks Worldwide to Feed Global Espionage System”—is one of the clearest, broadest warnings ever issued about a Chinese state-sponsored intrusion campaign. And, because the agencies involved designated it as not sensitive and may be shared publicly without restriction (TLP:CLEAR), you can read it yourself.

The World’s Telecom Backbones: Now Featuring Uninvited Guests

The intel agency advisory describes a “Typhoon class” global espionage ecosystem run through persistent compromises of backbone routers, provider-edge and customer-edge routers, ISP and telecom infrastructure, transportation networks, lodging and hospitality systems, government and military-adjacent networks.

This is not hypothetical. The advisory includes extremely detailed penetration chains: attackers exploit widely known “Common Vulnerabilities and Exposures” (CVEs) in routers, firewalls, VPNs, and management interfaces, then establish persistence through configuration modifications, traffic mirroring, injected services, and encrypted tunnels. This lets them monitor, redirect, copy, or exfiltrate traffic across entire service regions.

Put plainly: if your internet service provider has a heartbeat and publicly routable equipment, the attackers have probably knocked on the door. And for a depressingly large number of large-scale network operators, they got in.

This is classical intelligence tradecraft. The PRC’s immediate goal isn’t ransomware. It’s not crypto mining. It’s not vandalism. It’s good old-fashioned espionage: long-term access, silent monitoring, and selective exploitation.

What They’re Collecting: Clues About Intent

The advisory makes the overall aim explicit: to give PRC intelligence the ability to identify and track targets’ communications and movements worldwide.

That includes metadata on calls, enterprise-internal communications, hotel and travel itineraries, traffic patterns for government and defense systems, persistent vantage points on global networks.

This is signals intelligence (SIGINT), not smash-and-grab.

And importantly: this kind of operation requires enormous intelligence-analytic processing, not a general-purpose “LLM training dataset.” These are targeted, high-value accesses, not indiscriminate web scrapes. The attackers are going after specific information—strategic, diplomatic, military, infrastructure, and political—not broad consumer content.

So no, this advisory is not about “AI training.” It is about access, exfiltration, and situational awareness across vital global communications arteries.

Does This Tell Us Anything About TikTok?

Officially, no. The advisory never mentions TikTok, ByteDance, or consumer social media apps. It is focused squarely on infrastructure.

But from a strategic-intent standpoint, it absolutely matters. Because when you combine:

1. Global telecom-layer access
2. Persistent long-term SIGINT footholds
3. The PRC’s demonstrated appetite for foreign behavioral data
4. The existence of the richest behavioral dataset on Earth—TikTok’s U.S. user base

—you get a coherent picture of the intelligence ecosystem the Chinese Communist Party is building on…I guess you’d have to say “the world”.

If a nation-state is willing to invest years compromising backbone routers, it is not a stretch to imagine what they could do with a mobile app installed on the phones of oh say 170 million Americans to pick a random number that conveniently collects social graphs, location traces, contact patterns, engagement preferences, political and commercial interests that are visible in the PRC.

But again, don’t worry. The advisory suggests only that Chinese state actors have global access to the infrastructure over which your TikTok traffic travels—not that they would dare take an interest in the app itself. And besides, the TikTok executives swore under oath to the U.S. Congress that it didn’t happen that way so it must be true.

After all, why would a government running a worldwide intrusion program want access to the largest behavioral-data sensor array outside the NSA?

If you still believe the PRC is nowhere near TikTok’s data, then this advisory will reassure you: it’s just a gentle reminder that Chinese state actors are burrowed into global telecom backbones, hotel networks, transportation systems, and military-adjacent infrastructure—pure souls simply striving to make sure your “For You” page loads quickly.

After all, why would a government running a worldwide network-intrusion program have any interest in the richest behavioral dataset on Earth?
