How Salt Typhoon & Volt Typhoon Forced a U.S. Critical Infrastructure Cybersecurity Rethink
Between 2021 and 2023, advanced Chinese threat actors known as Salt Typhoon and Volt Typhoon conducted highly covert cyber intrusions targeting U.S. telecommunications networks and critical infrastructure sectors. These groups utilized advanced tactics such as "living off the land," abusing legitimate administrative tools, and blending into east-west network traffic, making detection and remediation extremely challenging for defenders. Their primary objectives ranged from long-term espionage and persistent access to prepositioning for potential disruptive attacks in the event of geopolitical conflict. The hacks led federal agencies like the FBI and CISA to revise investigative methods, shifting to assume attackers may already be inside the network and forcing collaboration to uncover subtle anomalies rather than clear indicators.
This incident is indicative of a broader industry trend: state-backed actors increasingly focus on stealth, cloud environments, and edge devices, targeting managed service providers and exploiting blind spots in monitoring. Their evolving tactics closely align with growing regulatory and CISO concern for stronger east-west visibility, zero trust controls, and continuous threat hunting across hybrid cloud infrastructure.

TP-Link Routers Hit by 2025 Zero-Day: What You Need to Know About the CWMP Exploit
In September 2025, TP-Link confirmed a critical zero-day vulnerability impacting multiple router models, including Archer AX10 and AX1500. Discovered by independent researcher Mehrun (ByteRay), the stack-based buffer overflow exists within the routers' CWMP (CPE WAN Management Protocol) implementation, specifically in handling SOAP messages due to improper validation in 'strncpy' calls. Attackers can exploit this flaw to achieve remote code execution by redirecting devices to malicious CWMP servers or leveraging unchanged default credentials, leading to device compromise. Once compromised, adversaries can reroute DNS queries, intercept traffic, and inject malicious payloads, raising severe risks for users and organizations relying on affected devices.
The continued exploitation of similar router vulnerabilities by groups like Quad7 botnet highlights a shift in attacker TTPs towards leveraging consumer and SOHO networking devices as entry points and persistence mechanisms. The prevalence of these attacks underscores the urgent need for robust patch management and secure configuration in edge infrastructure.
