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.

CanisterWorm: npm Publisher Compromise Deploys Backdoor Across 29+ Packages

CanisterWorm is a worm-enabled supply chain attack that compromises legitimate npm publisher accounts to distribute a Python backdoor. The malware establishes user-level Linux persistence via systemd and utilizes an Internet Computer Protocol (ICP) canister as a dead-drop C2 to continuously fetch and execute secondary payloads, while simultaneously harvesting npm tokens to propagate itself to other packages.
