What happened
In late 2022, the music streaming service Deezer disclosed a data breach that impacted over 240M customers. The breach dated back to a mid-2019 backup exposed by a 3rd party partner which was subsequently sold and then broadly redistributed on a popular hacking forum. Impacted data included 229M unique email addresses, IP addresses, names, usernames, genders, DoBs and the geographic location of the customer.

What to do if you were affected
These steps are ordered for this specific breach — the most urgent action given what leaked comes first.
- Dates of birth
Never confirm your date of birth to an inbound caller — hang up and dial the organisation back on a published number. - Location data
Review location sharing on the accounts you still hold with this service. - Names and usernames
Search your usual username to see what else it exposes, and use distinct handles for sensitive accounts. - Email addresses
Treat any message referencing this service with suspicion, and never act on links in unexpected emails. - IP addresses
No direct action needed, but be wary of anyone quoting your location as “proof” of identity. - Confirm you were actually in it
Run a free scan before you spend time on the steps above.
How urgent is this now?
This breach is over 7 years old. Old credentials still cause harm — leaked passwords from a decade ago are still tried against new accounts every day.
Remember: a breach can’t be “un-leaked” — once a database is out, it exists in countless copies. The goal is to make the leaked data useless: change what can be changed, lock down what can’t, and remove what has been republished.
