What happened
In January 2022, a vulnerability in Twitter's platform allowed an attacker to build a database of the email addresses and phone numbers of millions of users of the social platform. In a disclosure notice later shared in August 2022, Twitter advised that the vulnerability was related to a bug introduced in June 2021 and that they are directly notifying impacted customers. The impacted data included either email address or phone number alongside other public information including the username, display name, bio, location and profile photo. The data included 6.7M unique email addresses across both active and suspended accounts, the latter appearing in a separate list of 1.4M addresses.
What data leaked

What to do if you had an account
- Turn on two-step sign-in. Enable two-factor authentication where the service offers it, preferably with an authenticator app or a passkey. A leaked password alone is then not enough to get in.
- Expect targeted phishing. Leaked contact details are used to write convincing fake messages that mention the breached company or your real name. Do not click links in unexpected emails or texts about this account; go to the site by typing its address.
- Watch for scam calls and SIM swaps. Be suspicious of calls and texts that claim to be from your bank or a courier. Ask your mobile operator for a port-out or SIM-change PIN if it offers one.
