• Incident Details: Microsoft Defender for Endpoint experienced a 10-hour portal outage, affecting XDR (Extended Detection and Response) features like advanced threat hunting, alerts, and device visibility.
• Root Cause: Microsoft blamed the disruption on a CPU spike due to high portal component traffic.
• Impact & Recovery:
  • Most customers' portal access restored after mitigation steps.
  • Some organizations still face ongoing issues.
  • Microsoft is collecting more diagnostics and monitoring system performance.
• Notable Quote:
  • "Microsoft attributed the disruption to a CPU spike from high traffic on portal components." (Sara Lane, 00:17)
  • "Mitigation steps have restored access for most customers, though some organizations still face issues." (Sara Lane, 00:25)

2. Apple Resists India’s State-Run App Order

Timestamps: 01:11–02:04

• Background: India orders phone manufacturers to preload a state-run cyber safety app (Sanchar Saathi) on all smartphones to track and block stolen devices.
• Apple’s Response:
  • Apple refuses to comply, citing privacy and security concerns.
  • Plans to escalate the issue with the Indian government.
• Industry Reactions:
  • Other major manufacturers (Samsung, Xiaomi) are reviewing the directive.
