Breach Database / Trello

Yes — Trello was breached.

What happened

In January 2024, data was scraped from Trello and posted for sale on a popular hacking forum. Containing over 15M email addresses, names and usernames, the data was obtained by enumerating a publicly accessible resource using email addresses from previous breach corpuses. Trello advised that no unauthorised access had occurred.

What data was exposed

What to do right now

  1. Expect convincing phishing emails. Attackers use breached details to write personalized emails. Be suspicious of any message referencing this service.
  2. Check your other accounts on Have I Been Pwned. Your email address may appear in other breaches you don't know about yet.
  3. Monitor the apps you use going forward. Clearly watches the breach record for the companies behind your apps and alerts you the moment one appears.
