Breach Database / Mac Forums

Yes — Mac Forums was breached.

What happened

In July 2016, the self-proclaimed "Ultimate Source For Your Mac" website Mac Forums suffered a data breach. The vBulletin-based system exposed over 326k usernames, email and IP addresses, dates of birth and passwords stored as salted MD5 hashes. The data was later discovered being traded on a popular hacking forum. Mac Forums did not respond when contacted about the incident via their contact us form.

What data was exposed

What to do right now

  1. Change your password for this service now. And change it anywhere you reused the same password — attackers try leaked passwords on other sites within hours ("credential stuffing").
  2. Turn on two-factor authentication. Even a leaked password is useless against an account protected by a second factor. Prefer an authenticator app over SMS.
  3. Expect convincing phishing emails. Attackers use breached details to write personalized emails. Be suspicious of any message referencing this service.
  4. Check your other accounts on Have I Been Pwned. Your email address may appear in other breaches you don't know about yet.
  5. 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.
