The Breach Risk Index (BRI) is a proprietary 0–100 score rating how dangerous a breach is right now, based on how recently the data has been circulating on the dark web and how valuable it is to attackers.
Breach Summary
In October 2016, Dailymotion suffered a data breach exposing about 85.2 million unique email addresses and usernames. Roughly 18.3 million of the accounts also had passwords, stored as bcrypt hashes with 10 rounds, making them difficult to crack. The attacker was not identified.

About Dailymotion
Dailymotion is a large video-sharing platform where users upload, watch, and share video content to a global audience.
Why They Hold Your Data
Video-hosting platforms collect user accounts, emails, uploads, viewing history, social activity, and ad-linked behavioral data across content-distribution workflows.
Recent Developments
Dailymotion continued operating after the incident. Only a minority of the exposed accounts carried passwords, and those were protected with a strong bcrypt hash.

Username
Breach Impact
Bcrypt hashing substantially limited password recovery, so the primary exposure is the email/username set, useful for spam, phishing, and account enumeration.
Exploitation & Downstream Threats
• Credential stuffing against reused passwords across other platforms | • Targeted phishing campaigns using exposed email addresses
Principal Risk Advisory
What this means for a principal
A consumer-service breach: contact and account data supports phishing, account takeover and profile enrichment. For a high-profile principal the main risk is credible impersonation and enrichment of existing exposure.
What You Should Do
- Reset any reused passwords and enable MFA on email first, then financial accounts.
- Do not use unofficial 'am I affected' lookups; several are themselves harvesting operations.
How ObscureIQ Can Help
- Corpus confirmation: determine whether and where the principal (plus household and staff) appear in this dataset and which specific fields are exposed for them.
- Exposure mapping: cross-reference the exposed identifiers against broker-available data to size and prioritize the principal's wider footprint.
- ThreatWatch tuned to this incident's identifiers and misuse pattern (impersonation and targeting patterns, not generic credential monitoring).
