Virgin Media 2020: 900,000 People in an Unsecured Marketing Database
On 28 February 2020, Virgin Media confirmed that a marketing database containing the personal details of around 900,000 people had been left insecure and accessible online, discovered not by criminals but by a researcher during unrelated work. The dataset, stored on an unsecured cloud instance, included names, home and email addresses, and phone numbers, and had been reachable for at least ten months. This post explains exactly what was exposed, how the misconfiguration happened, how Virgin Media responded, and what happened next: a textbook non-hack data breach that still required full disclosure, notification, and regulatory scrutiny.
