What happened

In 2024, data relating to an unknown service referred to as "Hopamedia" and dating back to 2020 appeared in a publicly exposed database. The data included almost 24M records of email address, name, phone number, the country of the individual and their telecommunications carrier.

What was exposed, and why it matters

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

Phone numbers

Enables SIM-swap attacks (hijacking your number to intercept SMS codes), smishing, and voice scams that appear to come from your bank.

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.

Also listed in this breach: Email addresses, Geographic locations, Names, Phone numbers, Telecommunications carrier.

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. Phone numbers: Move two-factor authentication off SMS to an authenticator app or passkey, and add a port-out PIN with your mobile provider.
  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. 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 6 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.
