Data breach
A security incident where personal data is lost, stolen, destroyed or seen by someone who shouldn't see it. Serious ones must be reported to the ICO within 72 hours.

Why it matters to you.
The 72-hour clock starts when you become aware of it, so report suspicions to the right people at once rather than investigating quietly first.
