Twitter (200M) Data Breach

What happened?

In early 2023, over 200M records scraped from Twitter appeared on a popular hacking forum . The data was obtained sometime in 2021 by abusing an API that enabled email addresses to be resolved to Twitter profiles. The subsequent results were then composed into a corpus of data containing email addresses alongside public Twitter profile information including names, usernames and follower counts.

When did it happen?

The breach date in the public record is January 1, 2021. The record was added to the catalogue on January 5, 2023 and last updated there on January 5, 2023.

What information was reported as exposed?

• Email addresses
• Names
• Social media profiles
• Usernames

These are incident-level categories. The record does not prove that every category was exposed for every affected person.

Who may be affected?

This record may be relevant to people who had an account or other relationship with Twitter (200M) or used twitter.com around January 1, 2021. A catalogue entry does not establish that every customer was affected or that every listed data category applied to each person. Compare the record with an official notice addressed to you.

What should you do?
