🚨 HEADLINE ALERTSAsahi Group OT/Supply-Chain Disruption Triggers National Shortages (Japan) A sustained cyberattack halted Asahi’s order processing, shipping, and call center systems, cascading into production shutdowns across domestic breweries and visible retail shortages. OT dependencies, vendor connectivity, and manual workarounds expose critical gaps in operational resilience and incident playbooks. Immediate actions: segment OT networks, validate vendor access, and rehearse manual recovery. More info: Reuters 2025-10-03reuters+2
AI Is Now the Prime Vector for Data Exfiltration Risk New analysis indicates the majority of sensitive data exfiltration events now leverage AI-assisted automation for harvesting, staging, and exfil—accelerating dwell time-to-impact and increasing the difficulty of traditional DLP. Revisit insider risk, prompt injection exposure in SaaS, and telemetry capture from AI tooling. More info: The Hacker News 2025-10-06cyware
