How to protect yourself from malware?

Once on the device, the virus monitors its activity until it detects that a bill is about to be paid. It then alters the bill's code, switching the issuer's account to the hackers'.

Unlike other viruses that are detected quickly, malware takes time to leave traces. Only when the company notifies the customer that the bill is outstanding does the problem occur. Therefore, it becomes difficult to recover the lost amount.


The best way is to anticipate the scam. How? Well, a few basic tips can increase your protection and prevent malware from harming you.

Overall, invest in a good antivirus. We know that paid shop ones are good options, but not just any paid antivirus will protect you well. Get good reviews before installing a program on your computer, even if it's just for protection purposes.

Avoid opening any links from unknown sender, whether by email, WhatsApp, or social media.

Regarding the bill, pay attention to the following points:

First, observe the general information on the bill;
If you suspect something, access the FEBRABAN search;
check the name of the issuing bank and compare it with the logo on the bill;
the bank number must be at the beginning of the boleto code;
Regardless of the bank, the bill code must include the branch, payer and amount.

After all this, if you still have questions, it's worth contacting the issuing bank and making sure the bill is correct.
If you have computers on a shared network, consider leaving at least one computer off the network exclusively for payments. This way, you prevent a breach on one PC from affecting all the other devices.
