If you've ever had an account or relationship with DailyMotion, it's worth checking whether your personal data was exposed in this incident. Here's what happened, what data was involved, and what to do about it.
What Happened
DailyMotion, the video-sharing platform, disclosed a data breach in December 2016 after discovering unauthorized access to a database of user account information. The breach was estimated to affect around 85 million user accounts.
What Data Was Exposed
The exposed data included usernames, email addresses, and for approximately 18 million of the affected accounts, bcrypt-hashed passwords. DailyMotion stated no financial information was involved, as it does not store payment data directly.
Why This Still Matters
Exposed data doesn't expire. It's sold, traded, and reused for years, fueling credential stuffing attacks — automated attempts to reuse your email and password combination across other sites. If you reused a password anywhere, one old exposure can compromise several current accounts.
