Data breach — High

In August 2024, MC2 Data suffered a data breach. 2.1 million accounts were affected. The exposed data includes email addresses, names and passwords.

| Fact | Value |
| --- | --- |
| Disclosed on | December 15, 2024 |
| Incident dated | August 18, 2024 |
| Accounts affected | 2.1M |
| Sector | Digital services |
| Country | International or undetermined |
| Cause | Undisclosed |
| Severity | High |
| Status | Confirmed |

## Exposed data

- Email address
- Full name
- Password (hashed)

## What you can do

- Change that password — and everywhere you reused it. That is how a leak spreads to your other accounts.
- Turn on two-factor authentication on the affected accounts: a stolen password is then no longer enough.
- Expect phishing attempts quoting your name and this company. A message that knows your details is not legitimate for that reason.
- You can ask the organisation exactly what was exposed about you (right of access), and complain to the DPA if no answer comes within a month.
