Trello data breach — are you affected?

In January 2024 data scraped from Trello was offered for sale on a hacking forum. It holds over 15 million email addresses with names and usernames, collected by enumerating a publicly reachable resource with addresses taken from earlier breaches. Trello stated that no unauthorised access to its systems took place; no passwords are involved.

What this means for you

Based on the types of data in this breach, in order of importance.

  • Expect more targeted phishing

    Your email address ties you to this service, which is enough for a believable message such as a fake account warning. Check the sender and the web address before you sign in, and go to the site directly instead of using links in email.

  • Limit what attackers can personalise

    Names, employers, job titles and social profiles make impersonation and spear-phishing easier. Check what your public profiles reveal, and be careful with unexpected requests that use your real name or workplace.
