Massive Data Breach in Mexico: What the 2.3 TB Hack Means for You and How to Protect Yourself Today

In recent days, Mexico has awakened to news that seems straight out of a spy movie, but whose consequences are very real: the hacker group Chronus managed to breach the security of over 25 government agencies (including IMSS-Bienestar and SEP).

‍

The figure? 2.3 Terabytes of information. To give you an idea, this is not just "files"; it is the digital life of approximately 36 million Mexicans (or even more) circulating in the darkest corners of the Deep Web. CURPs, INE data, biometrics, and passwords are now in the hands of those looking to profit from your identity.

From Phishing to "Spear Phishing": When the Attack Has Your Name

What makes this hack particularly dangerous is not just the theft, but how they will use that data. With your real information, attackers now practice Spear Phishing: personalized attacks where the scammer knows who you are, where you live, and what pending transactions you have.

‍

Additionally, techniques like Spoofing allow that, when they call you, the legitimate name of your bank or an official institution appears on your screen.

5 Golden Recommendations to Protect Yourself Today

Digital security no longer depends solely on company filters, but on our judgment as users. Here are the steps you should take immediately:

‍

1. Apply the Golden Rule: "If you didn't initiate it, it's a scam"
If you receive a call from the SAT, your bank, or Meta, hang up immediately. No matter how real the voice or number seems. Hang up and contact the official numbers that appear on the back of your card or on legitimate websites.

‍

2. Enable Two-Factor Authentication (2FA)
If you receive a call from the SAT, your bank, or Meta, hang up immediately. No matter how real the voice or number seems. Hang up and contact the official numbers that appear on the back of your card or on legitimate websites.

‍

3. Beware of links in SMS and WhatsApp
After a massive breach, messages like "Your package is on hold" or "Suspicious login" multiply. Never click on the links. Access directly from the official app or browser by typing the address yourself.

‍

4. Change your passwords (especially if you reuse them)
If you use the same password for the government portal and your personal email, you are at risk. Use password managers to create unique, long, and complex passwords that have no relation to your personal data (like birth dates).

‍

5. Beware of "urgency"
Cybercriminals play with your emotions. If a message pressures you to act "within the next 5 minutes" to avoid a charge or a fine, take a breath. That urgency is the clearest sign that they are trying to prevent you from thinking clearly.
