Internet Archive data breach — are you affected?

In September 2024 the Internet Archive suffered a breach that exposed about 31 million user records. They hold email addresses, screen names and bcrypt password hashes. Bcrypt makes mass cracking slow, but a reused or weak password is still a risk.

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.
