Data breach — Moderate

In October 2023, Facebook Marketplace suffered a data breach. 77,267 accounts were affected. The exposed data includes email addresses, postal addresses, names, passwords and phone numbers.

| Fact | Value |
| --- | --- |
| Disclosed on | February 22, 2024 |
| Incident dated | October 1, 2023 |
| Accounts affected | 77,267 |
| Sector | Retail |
| Country | International or undetermined |
| Cause | Undisclosed |
| Severity | Moderate |
| Status | Confirmed |

## Exposed data

- Email address
- Postal address
- Full name
- Password (hashed)
- Phone number

## 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.
