Twitter (200M) data breach — are you affected?
In early 2023 a collection of over 200 million records appeared on a hacking forum. It had been assembled in 2021 by abusing an API that resolved email addresses to Twitter profiles, and pairs each email address with public profile information such as name, username and follower count. No passwords are involved, but the link between an email address and a social identity is valuable for phishing.

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.
Check your own email address
Run a free self-assessment for an email address you own. VINDICIS checks it against infostealer logs and several public breach sources and shows a summary in seconds.
