The "Mother of All Breaches" (MOAB)

1. What happened?

Security researchers discovered a massive, 12-terabyte database floating openly on the internet. This database, dubbed the “Mother of All Breaches” (MOAB), contains over 26 billion leaked records. It is not a “new” hack of a single company, but rather a master compilation of thousands of past data breaches (like LinkedIn, Twitter, Dropbox, and Adobe) all merged into one giant, searchable file.

2. Am I affected?

Almost certainly, yes. Given the sheer size of the database (26 billion records), if you have been using the internet for more than a few years, it is highly likely that your email address and an old password are in this file.

3. Do I need to worry? (Risk Level: Medium)

You only need to worry if you reuse the same password across multiple websites.

Because this database makes it incredibly easy for hackers to search for your email, they can take an old password you used for a random forum in 2018 and try to use it to log into your bank account or Amazon today.

4. What should I do right now?

Follow these three steps to secure yourself immediately:

1. Check your exposure: Go to HaveIBeenPwned.com (a safe, free tool run by security researchers) and type in your email address. It will tell you exactly which companies lost your data in the past.
2. Change reused passwords: If you have been using the exact same password for multiple websites, you must change it immediately on your most important accounts (Email, Banking, Amazon, Social Media).
3. Turn on MFA: Enable Multi-Factor Authentication (MFA) on your primary email account (like Gmail or Outlook). If your email account is safe, hackers cannot reset passwords for your other accounts.

💡 The Permanent Fix: Start using a Password Manager to generate and remember unique passwords for every single website. Check out our Zero to Hero guide on Password Managers to get started!
