What this means for you
Based on the types of data in this breach, in order of importance.
Change the password and turn on two-factor authentication
Passwords or password hashes were part of this breach. Change the password on this service and on every site where you reused it, use a unique password for each account from a password manager, and enable two-factor authentication. You can test a password without sending it anywhere with the password checker.
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.

Is it safe to check my email address on VINDICIS?
