Trellix’s October 2025 CyberThreat Report describes a Q2–Q3 2025 threat landscape shaped by rising detections, advanced threats, AI-powered malware, supply-chain exploitation, and attacks on developed economies and critical infrastructure. The excerpt highlights ToolShell SharePoint zero-day exploitation, AI-driven phishing, disruptive ransomware against manufacturers and airlines, and broader convergence between nation-state operations and financially motivated cybercrime. Russian-aligned activity is described as increasing alongside military escalation in May and June 2025 before declining by 48% between August and September in Trellix telemetry. Iran-aligned activity is also covered, with a June 2025 shift toward Israeli targets during the Israel–Iran conflict and later resumed operations against global energy, oil and gas, and government targets. The provided excerpt does not include a North Korea-specific section, so the supported value is contextual threat-landscape framing rather than actor-specific DPRK tradecraft.
