Notes
- Observed events reflect monitored leak-site and extortion activity, not independent confirmation of every intrusion.
- Data-leak indicators reflect visible public leak evidence or escalation, which is stronger than a fresh listing alone.
- Country, sector, and company-size metadata can be incomplete. Unknown values are excluded from the public mix views.
- The goal is to explain concentration, escalation, churn, and patterns — not to build a wall of named victims.
Method
- The page uses a fixed seven-day window based on the selected date.
- Only public-facing actor and event records are included.
- Counts and breakdowns are designed for trend review, not incident confirmation.
