Security Experts:

Millions of User Accounts Allegedly Stolen From Dailymotion

Data breach notification service LeakedSource has obtained a database containing the details of roughly 85 million Dailymotion users, including usernames, email addresses and, in many cases, passwords.

According to LeakedSource, the database stores 87 million records with 85 million unique email addresses. More than 18 million of the entries also include password hashes. LeakedSource said the hackers claimed to have stolen the data on around October 20.

SecurityWeek has analyzed a sample of nearly 10,000 entries and determined, based on LeakedSource and Have I Been Pwned searches, that many of the accounts had not been compromised in previous breaches.

It’s also worth noting that tens of usernames and email addresses in the sample reference Dailymotion, which could indicate that the data comes from the systems of the video-sharing service.

The passwords have been hashed using the bcrypt algorithm, which makes mass cracking a difficult task. However, if attackers want to target a specific user, they may be able to crack the password.

SecurityWeek has reached out to Dailymotion for comment and will update this article if the company responds.

LeakedSource has already disclosed many important breaches and it plans on sharing information on 20-30 more by the end of the year. In some cases, the data was obtained by hackers several years ago, but many of the affected companies never notified their customers and they may have not even known about the breach.

One of the recently disclosed incidents involves six websites operated by FriendFinder Networks and its subsidiaries. Hackers managed to steal more than 400 million accounts belonging to users of Adult Friend Finder, Cams.com and various other adult sites.
