Security News > 2022 > January > Have I Been Pwned warns of DatPiff data breach impacting millions
The cracked passwords for almost 7.5 million DatPiff members are being sold online, and users can check if they are part of the data breach through the Have I Been Pwned notification service.
It is unclear when the data breach occurred, but the DatPiff database was first sold privately and then publicly on hacking forums in July 2020.
The passwords in the database could be cracked because DatPiff hashed them with the MD5 algorithm, an old cryptographic hash function that is considered obsolete and insecure, especially for securing passwords.
It is believed that the threat actor did not breach the actual DatPiff website but rather a server with old database backup.
DatPiff members can search for their email addresses on the Have I Been Pwned data breach notification services to see if they are one of the over 7 million users impacted by this breach.
At the time of writing this, DatPiff hasn't published a statement on this data breach incident, hasn't sent any notices to users, and hasn't forced a password reset.
