A bank account hack requires immediate action
If you noticed suspicious activity, transfers you do not recognize, or lost access to the app, your account may have been compromised.
In situations like this, every minute matters.
1. Block access as quickly as possible
Your first action should be to stop further transactions.
Use another device if necessary and contact support immediately.
Request:
- • Account blocking
- • Transaction suspension
- • Investigation of suspicious activity
2. Check what was done in the account
Review your recent account history.
Look for:
- • Pix transfers
- • Unknown payments
- • Changes to account information
Take screenshots and document everything.
3. Change your passwords immediately
Do not change only your banking password.
Also update:
- • Social media accounts
- • Other financial apps
Many account breaches start with leaked passwords.
4. Check if your phone number was compromised
In many cases, the attack involves SIM swapping or phone number cloning.
If you lost signal or stopped receiving SMS messages, contact your mobile carrier immediately.
5. File a police report
This is important to formally document the case.
It may also help during refund investigations.
How to avoid future attacks
Most attacks happen because of simple security failures:
- • Weak passwords
- • Password reuse
- • Using SMS as the main security method
Using a password manager greatly reduces these risks.

- • Create strong and unique passwords
- • Generate 2FA authentication codes

- • Monitor data breaches
- • Receive security alerts

Having your Nubank account hacked is a serious situation, but acting fast makes a huge difference.
Blocking access, changing passwords, and reviewing your digital security are essential steps.
