Spin the wheel, land on a real company, and face its biggest data breach: how many records, how it happened, what it cost. Data breach news usually arrives as abstract millions; the roulette makes it concrete — every spin is a real incident with a real cause, and the patterns repeat embarrassingly often.
Scale without context: five hundred million records is too large to visualize, so readers shrug. The roulette fixes this by attaching each number to a company you know and a cause you can understand — an unpatched server, a phished employee, a misconfigured bucket. Once breaches have faces, the lesson lands: most mega-breaches trace back to basic hygiene failures, not exotic zero-days.
A data breach is an incident where confidential information is accessed, stolen, or exposed without authorization — from customer records to credentials. Breach-notification laws in most jurisdictions require companies to disclose significant breaches.
Spin the wheel. Land on a real company. See its real, publicly reported data breach — how many records, what it cost them, with source links to the reporting. Every entry is documented. The lesson: this happens to the biggest companies on earth. Don't let it happen to you.
