Descomplica data breach

What happened

In March 2021, the Brazilian EdTech company Descomplica suffered a data breach which was subsequently posted to a popular hacking forum. The data included almost 5 million email addresses, names, the first 6 and last 4 digits and the expiry date of credit cards, purchase histories and password hashes.

What data leaked

• Email addresses
• Names
• Partial credit card data
• Passwords
• Purchases

What to do if you had an account

1. Change the password. Change your password on this service. If you used the same password anywhere else, change it there too: attackers try leaked email and password pairs on other sites automatically. A password manager makes one unique password per site practical.
2. Turn on two-step sign-in. Enable two-factor authentication where the service offers it, preferably with an authenticator app or a passkey. A leaked password alone is then not enough to get in.
3. Expect targeted phishing. Leaked contact details are used to write convincing fake messages that mention the breached company or your real name. Do not click links in unexpected emails or texts about this account; go to the site by typing its address.
4. Check your bank statements. Review recent card and account transactions and report anything you do not recognise. If full card numbers were exposed, ask your bank to replace the card.
