Breach Database / Twitter

Yes — Twitter was breached.

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 was exposed

What to do right now

  1. Be alert for smishing and SIM-swap attempts. Treat unexpected texts and "carrier" calls with suspicion; add a PIN/port-freeze with your mobile carrier.
  2. Expect convincing phishing emails. Attackers use breached details to write personalized emails. Be suspicious of any message referencing this service.
  3. Check your other accounts on Have I Been Pwned. Your email address may appear in other breaches you don't know about yet.
  4. 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.
