What happened in the Trello breach?

Trello (trello.com) was hit by a data breach dated January 2024, exposing around 15 million accounts. Incidents like this happen when attackers break into a company’s user database, or when a misconfigured server or third-party partner leaks it — and the stolen records then spread among other criminals.

The exposed records included email addresses, names and usernames. Leaked data doesn’t simply disappear: it gets copied, sold and re-posted across breach forums and dark-web markets for years. That’s why your information from the Trello breach can still be abused long after the original incident — and why checking your exposure and locking down your accounts matters even now.

What data was exposed in the Trello breach?

The Trello breach exposed email addresses, names and usernames. The more of these are tied to you, the more ways an attacker can impersonate you or break into your other accounts.

How the leaked Trello data can be used against you

Because the Trello breach exposed email addresses, names and usernames, your email address becomes a target for convincing phishing, often referencing this very breach to look legitimate.

How to check if you were affected

The leaked records themselves aren’t published openly, so the way to know is to check your email against known breach and dark-web databases. Our free tool does exactly that in a few seconds — no account needed.

What to do if your Trello account was breached

These steps are prioritized for exactly the kind of data the Trello breach exposed.

1
Turn on two-factor authentication

Add 2FA — ideally an authenticator app or a passkey rather than SMS — to your email, banking and other important accounts, so a stolen password alone can’t get in.

2
Watch for targeted phishing

Scammers reference real breaches to sound credible, so treat any email mentioning Trello with suspicion, and never use a password-reset link you didn’t request — go to the site directly instead.

3
Monitor whether your data resurfaces

Leaked data is resold for years, so a one-time clean-up isn’t enough. Ongoing breach and dark-web monitoring tells you the moment your details reappear, so you can act before an account is misused.
