International cyber agencies share fresh advice to defend against China-linked covert networks Executive Summary: Defending against China-nexus covert networks of compromised devices China-nexus threat actors are increasingly leveraging compromised SOHO and edge devices to form dynamic covert networks. These botnets facilitate various stages of cyber attacks while rendering traditional static indicators of compromise obsolete, necessitating adaptive defense strategies like traffic baselining and zero trust architecture.
M-Trends 2026: Data, Insights, and Strategies From the Frontlines Mandiant's M-Trends 2026 report highlights a severe divergence in adversary tactics. Cybercriminals are optimizing for speed, with initial access hand-offs collapsing to 22 seconds, and focusing on recovery denial by targeting hypervisors and backup infrastructure. Conversely, espionage groups are prioritizing extreme persistence by exploiting zero-days and deploying in-memory malware on unmonitored edge devices, while voice phishing has emerged as a primary vector for bypassing MFA and compromising SaaS environments.
