Salt Typhoon, a Chinese state-backed hacking group, breached global telecom networks, including in Canada. The Salt Typhoon cyber-espionage activities shook the industry and exposed deep security flaws.
Opening Summary
Salt Typhoon, a cyber-espionage group linked to China, broke into telecom networks across the world. Canada was among the victims. Hackers used router flaws to sneak inside and stay there. This gave them long-term access to sensitive data and everyday communications.
Why It Matters
Salt Typhoon’s campaign did not just target one country. Instead, it spread across more than 80 nations. The group focused on telecom firms, but they also looked at governments, militaries, and critical infrastructure (SecurityWeek).
In Canada, attackers used a router flaw in early 2025 to break into a provider’s network (Industrial Cyber). This let them watch traffic or launch more attacks. The FBI later confirmed that hackers hit more than 600 organizations, including lawful wiretap systems in the U.S. (Nextgov).

A Closer Look at How It Unfolded
Behind the Devices—What Made This Possible
Salt Typhoon exploited well-known vulnerabilities in routers and edge-network devices—from Cisco to Ivanti and Palo Alto Networks. These date back years, allowing them to embed themselves in telecom infrastructure and evade detection. They modified firmware, altered access control lists, opened covert ports, and created GRE tunnels. These were all strategies that helped them stay hidden and anchored in the systems.
Beyond Canada, U.S. telecoms like Verizon, AT&T, Lumen, and T-Mobile were among the reported victims. Sensitive communications—including those of high-profile political figures—were likely compromised (Reuters).
Voices and Context—Why This Story Deserves a Fresh Perspective
- Expert insight: Marc Rogers, a telecom cybersecurity veteran, praised the joint advisory for leveling the playing field for defenders overwhelmed by this stealthy adversary.
- Analyst notes: John Hultquist from Google’s Threat Intelligence Group pointed out Salt Typhoon’s “deep familiarity” with telecom tech. This gives them a significant edge in evading defenses.
- Public sentiment: The idea that “nearly every American” may have been swept up in the breach struck a nerve. It was a digital surveillance nightmare made real (El País).
What’s missing from coverage so far? The human toll. Infrastructure engineers race to undo stealthy code changes. Infosec teams are haunted by uncertainty, and civilians communications, however mundane, might have been exposed.

Impacts—Now and Later
Short-Term:
- Urgent efforts to deploy patches and hunt down intrusions across telecom providers.
- Government sanctions: The U.S. Treasury sanctioned implicated entities like Sichuan Juxinhe Network Technology Co. and a hacker named Yin Kecheng for their role in the campaign (AP News).
- Public outrage and erosion of trust in communications security.
Long-Term:
- A heightened focus on hardening edge devices and demanding stronger vendor accountability.
- Expanded intelligence sharing and joint alerts among allies (Canada, U.S., U.K., Germany, Japan, and more).
- A rethinking of global telecom standards: from design to oversight to resilience.
Final Takeaway
Salt Typhoon isn’t just a headline. It’s a wake-up call. This stealthy, long-running espionage campaign exploited foundational trust—our telecom systems—and slipped through the gaps. But the response is evolving. With scrutiny, action, and transparency, we can move toward a more resilient communications future.
