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 was exposed, and why it matters

Not all breaches carry the same risk — what matters is which fields leaked. Here is what the Deezer breach exposed and what each item actually enables:

Dates of birth

Date of birth is a permanent identifier used to verify identity by phone. Combined with a name and address it is often enough to impersonate you.

Location data

Reveals where you live, work or travel, which supports both targeted scams and physical-safety risks.

Names and usernames

Links this leak to your other accounts — a reused username lets anyone build a profile of you across platforms.

Email addresses

Puts you on spam and phishing lists, and confirms to attackers that you hold an account with this service — which makes impersonation emails more believable.

IP addresses

Reveals your approximate location and internet provider, which adds credibility to targeted scams.

Also listed in this breach: Dates of birth, Email addresses, Genders, Geographic locations, IP addresses, Names, Spoken languages, Usernames.

What to do if you were affected

These steps are ordered for this specific breach — the most urgent action given what leaked comes first.

  1. Dates of birth: Never confirm your date of birth to an inbound caller — hang up and dial the organisation back on a published number.
  2. Location data: Review location sharing on the accounts you still hold with this service.
  3. Names and usernames: Search your usual username to see what else it exposes, and use distinct handles for sensitive accounts.
  4. Email addresses: Treat any message referencing this service with suspicion, and never act on links in unexpected emails.
  5. IP addresses: No direct action needed, but be wary of anyone quoting your location as “proof” of identity.
  6. Check whether your own email appears in this breach — run a free scan to confirm 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.
