The usernames and emails of more than 85 million users of the video sharing site Dailymotion have been stolen in a data breach, Leakedsource reported.
The leak also reportedly contained 18m passwords protected by the Bcrypt hashing algorithm, meaning they should be difficult to crack.
Nevertheless, Dailymotion “strongly advises” that all users change their passwords in light of the breach.
Users are also advised to change the password on any other sites where it was used, and to use a password manager.
In a statement, the site said the hack appears to be limited, and no personal data has been compromised.
Dailymotion added: “It has come to our attention that a potential security risk, coming from outside Dailymotion may have comprised the passwords for a certain number of accounts.”
Leakedsource, a breach detection company, said that the details were stolen on 20 October, the BBC reported.
The Daily Motion hack is just the latest in a long line of breaches revealed in 2016.
In September, Yahoo confirmed that more half a billion users’ data had been compromised in a breach.
More than 1.5 billion stolen credentials are now believed to be available to hackers online.
