The June 25, 2026 threat landscape is dominated by three converging attack classes: active exploitation of network edge and OT devices with CISA-mandated remediation deadlines (Lantronix EDS5000, Ubiquiti UniFi OS, and Cisco Catalyst SD-WAN zero-days), a credential and session theft supply chain exposed by the StealC/Amadey MaaS takedown, and a new generation of living-off-trusted-frameworks attacks weaponizing ClickOnce and browser Native Messaging APIs for privilegeless ransomware staging. Immediate attention is required for the Lantronix KEV (CISA deadline June 26, 2026) and Cisco SD-WAN zero-day chain (EPSS 94.98th percentile, APT-confirmed exploitation). The underlying thread connecting all scenarios is identity: harvested credentials, stolen tokens, orphaned AI agent identities, and authentication bypasses are the common currency enabling initial access, persistence, and impact across every active campaign.
