Data breach — Critical

In July 2015, Ashley Madison suffered a data breach. 31 million accounts were affected. The exposed data includes dates of birth, email addresses, names, passwords, banking data, phone numbers, postal addresses, account identifiers and connection data.

| Fact | Value |

| Disclosed on | August 18, 2015 |
| Incident dated | July 19, 2015 |
| Accounts affected | 31M |
| Sector | Digital services |
| Country | International or undetermined |
| Cause | Undisclosed |
| Severity | Critical |
| Status | Confirmed |

## Exposed data

- Date of birth
- Email address
- Full name
- Password (hashed)
- Banking data (IBAN, card)
- Phone number
- Postal address
- Customer ID
- Connection data (IP, logs)

## 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.
- Watch your statements. On any unknown debit, block the card and request a refund — French law (art. L133-18) entitles you to it.
- 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.
